How To Hem Slacks Without A Sewing Machine: Easy Steps

Need to shorten your pants? Don’t have a sewing machine? No problem! You can hem slacks easily using methods like iron-on hem tape, fabric glue, or by hand sewing. These ways offer a quick hem without sewing machine use, perfect for a temporary hem solution or even a lasting fix, depending on the method chosen.

Deciphering Your Options: No-Sew vs. Hand Sew

When your pants are too long, you have a few choices that don’t need a sewing machine. These choices fall into two main groups: methods that don’t use thread and needle at all (no-sew) and methods that use a needle and thread but are done by hand.

The no-sew ways often use special tapes or glues. They are fast and simple. Hand sewing takes more time and a little skill with a needle, but it can look very clean and can be quite strong. Knowing these choices helps you pick the best way for your pants and your needs.

No-Sew Pant Hemming Methods

These ways are great if you need a fast fix. They are easy to do, even if you have never sewn anything.

Iron-On Hem Tape: This tape has glue on it. You iron it to stick the fabric together.
Fabric Glue: Special glue made for cloth. You just press the fabric edges together with glue in between.

Hand Sewing a Hem Tutorial

This way needs a needle and thread. It takes longer but can be stronger and look nicer on some fabrics.

Basic Hand Stitching: Simple stitches you make with a needle and thread.
Blind Hem Stitch: A special stitch that hides the thread, making the hem look very neat.

We will look closely at each of these ways. This will help you learn how to hem trousers by hand step by step or using no-sew items.

Getting Ready: Steps Before You Start

Before you hem your slacks, you need to do a few things. These steps make sure your hem is straight and looks good. This part is key for any hemming job, no matter how you do it.

Measure the Right Length

Getting the length right is the most important step.

Put on the pants and the shoes you will wear with them most often.
Stand straight and relaxed.
Ask a friend to help you. If you are alone, stand near a mirror.
Have your friend mark the spot where you want the bottom of the pant leg to be. They can use a pin or chalk. Mark it on the outside of the pant leg.
Do this for both legs. Make sure the marks are at the same height on both sides and both legs.
Take the pants off carefully so you don’t move the marks.

Mark the New Hemline

Now you need to mark the line where the hem will fold up.

Lay the pants flat on a table. Make sure they are smooth.
Use a ruler or a measuring tape. Measure from the mark you made earlier.
Measure up 1/4 inch (about 0.5 cm) from your first mark. Make a new mark here. This is your finished hemline.
Draw a line across the pant leg at this new mark. Use tailor’s chalk or a fabric pen that washes away. Do this all the way around the leg. This line shows where the bottom edge of the pants will be after you fold it up.

Mark the Cut Line or Fold Line

You need extra fabric to make a hem. How much extra depends on the method you use.

For Iron-On Tape or Hand Sewing: You need fabric to fold up twice. This is usually 1.5 to 2 inches (about 4-5 cm) below your finished hemline. Measure this distance down from the hemline you just drew. Draw another line here. This is your cutting line if the pants are very long, or your main fold line if you have just enough fabric.
For Fabric Glue (sometimes): You might only fold up once. Then you might only need 1 inch (about 2.5 cm) below the finished hemline. Measure this down from the hemline and mark it. This is your fold line.

Make sure these lines are clear on both pant legs.

Trim Extra Fabric (If Needed)

If your pants are much too long, you will have a lot of fabric below your lower marked line. You should cut this extra fabric off.

Lay the pant leg flat again.
Find your lowest marked line (the cut line).
Use sharp scissors to cut along this line. Cut through both layers of fabric at the same time if possible, keeping them flat.
Be careful to cut straight and evenly.
Do this for both pant legs.

After these steps, you have the pants ready to hem. You have marked the length, where the hem will be, and cut off extra fabric if needed. Now you can choose your hemming method.

Method 1: Quick Hem Without Sewing Using Iron-On Tape

Using iron-on hem tape for pants is a very popular no-sew pant hemming method. It’s fast, easy, and needs only a few things. This is a great choice for a quick fix or for fabrics that are hard to sew by hand.

What Iron-On Hem Tape Is

Iron-on hem tape is a thin strip of material. It has heat-activated glue on one or both sides. When you heat it with an iron, the glue melts and sticks the fabrics together. It creates a bond that holds the hem in place.

Materials Needed

Iron-on hem tape (sometimes called fusible hem tape or wonder web)
Iron
Ironing board
Damp cloth or pressing cloth
Measuring tape or ruler
Pins or clips
Tailor’s chalk or fabric pen
Scissors

How to Use Hem Tape: Step-by-Step

This is a simple process, great for a quick hem without sewing.

Step 1: Get the Hem Ready

Lay the pant leg flat with the inside facing up.
Find the finished hemline you marked earlier.
Fold the fabric up along this line. Make sure the line is right at the fold.
Press this fold with your iron to make a sharp crease. Let it cool.
Unfold the fabric.

Step 2: Prepare the Double Fold

Measure down from the finished hemline the amount you planned for the hem allowance (usually 1.5 to 2 inches). This is your lower fold line or raw edge if you trimmed.
Fold the raw edge of the fabric up so that the raw edge meets the finished hemline you marked. This creates a double fold. The raw edge is now hidden inside the fold.
Pin or clip this double fold in place around the pant leg.

Step 3: Insert the Hem Tape

Open up the second fold you just made, but keep the first fold pressed. You will see the raw edge and the crease where you folded it up to the hemline.
Place the iron-on hem tape inside this fold. Put the tape along the edge that you folded up (the raw edge).
Make sure the tape is tucked inside the fold, close to the edge, but not sticking out.
Cut the tape to fit the length of the hem around the pant leg. You can overlap the ends a little bit.

Step 4: Iron the Hem

Carefully fold the fabric back down over the tape, lining up the first crease you made (the finished hemline). The tape is now sandwiched between the two layers of the hem.
Lay the pant leg flat on the ironing board.
Place a damp cloth or pressing cloth over the hem area. This protects your fabric and helps the tape stick better by creating steam.
Press down firmly with a hot iron (check the tape instructions for the right heat setting). Do not slide the iron. Hold it in place for about 10-15 seconds on each spot.
Move the iron along the hem, pressing firmly, until you have ironed all the way around the leg.
Repeat for the other pant leg.

Step 5: Let It Cool

Let the hem cool down completely before you touch it or move the pants. The glue needs time to set and become strong. This can take a few minutes.

Pros and Cons of Iron-On Hem Tape

Pros:

Very fast and easy.
No sewing skills needed.
Looks clean and smooth on the outside.
Good for simple, straight hems.

Cons:

Can come undone over time or after many washes, especially with heavy fabrics or hot water/dryer.
Might not work well on very thick, very thin, or stretchy fabrics.
Can make the hem stiff.
Can be hard to remove if you make a mistake.
May not look as professional close up as a sewn hem.

Best No-Sew Hem Tape

There are many types of iron-on hem tape. Some are stronger than others. Look for tapes labeled “heavy duty” for thicker fabrics or more permanent results. Some popular types are fusible web or specific hem tapes by brands like Dritz or Stitch Witchery. Read reviews and check the fabric type the tape is made for. Using a quality tape helps the hem last longer.

Method 2: Hemming Clothes Using Fabric Glue

Fabric glue for hemming clothes is another simple no-sew method. It’s good for quick fixes and small jobs. It can be less stiff than hem tape on some fabrics.

What Fabric Glue Is

Fabric glue is a strong adhesive made to bond fabric together. Some are permanent, some are washable, and some are meant to be temporary. Make sure you use a fabric glue designed for hemming and check if it’s washable if you need it to last through laundry.

Materials Needed

Fabric glue (make sure it’s suitable for clothing and washable)
Pins or clips
Measuring tape or ruler
Tailor’s chalk or fabric pen
Scissors
Iron (optional, for pressing folds)
Damp cloth (for wiping away extra glue)

Step-by-Step Guide Using Fabric Glue

This method is very easy, needing no sewing machine or iron (though ironing folds first helps).

Step 1: Prepare the Hem Area

Lay the pant leg flat with the inside up.
Find the finished hemline you marked.
Fold the fabric up along this line. Press the fold with your fingers or an iron to make a crease.
Unfold.
Measure down from the finished hemline the amount for the hem allowance (usually 1 inch for a single fold with glue, or 1.5-2 inches for a double fold). Mark this line.
Trim off any extra fabric below this lower line.

Step 2: Create the Fold(s)

Single Fold (easier, less neat edge): Fold the fabric up once along the lower line you just marked (1 inch below the hemline). The raw edge will be visible inside the hem.
Double Fold (cleaner edge): Fold the fabric up once so the raw edge meets the finished hemline you marked earlier. Then fold up a second time along the finished hemline. The raw edge is hidden inside. This is usually about 1.5-2 inches total fold. Use pins to hold the fold(s) in place.

Step 3: Apply the Fabric Glue

Open up the final fold slightly.
Apply a thin, even line of fabric glue inside the hem fold.
- For a single fold: Put glue along the raw edge on the inside of the fold.
- For a double fold: Put glue between the two layers of fabric in the double fold, right along the upper crease (where the raw edge is hidden).
Do not use too much glue. Too much glue can soak through the fabric and make it stiff or show on the outside.
Apply the glue section by section, about 6-8 inches at a time.

Step 4: Press and Secure

Carefully press the fold back down, making sure the edges line up correctly.
Press firmly with your fingers or use clips or pins to hold the glued area together.
Wipe away any glue that comes out the sides right away with a damp cloth.
Continue applying glue and pressing sections until you go all the way around the pant leg.
Repeat for the other pant leg.

Step 5: Let It Dry

Let the glue dry completely. Drying time can be different for each glue. Check the bottle for how long. This often takes several hours, or even 24 hours, before you can wear or wash the pants.

Pros and Cons of Fabric Glue

Pros:

Very simple and quick to apply.
No tools like an iron needed (usually).
Can be flexible depending on the glue type.
Good for small fixes or temporary hems.

Cons:

Can look messy if too much glue is used.
May not hold up well in the wash, even if labeled washable.
Can make the fabric stiff or hard.
Might not be strong enough for heavy fabrics or high-stress areas.
Hard to remove once dry if you make a mistake.
Not suitable for all fabric types.

Method 3: Hemming Trousers By Hand Step By Step

Hemming pants by hand using needle and thread takes more effort than no-sew methods, but it can give you the most professional and lasting result. It’s a classic method and gives you control over the stitch type and look. This hand sewing a hem tutorial will show you how.

Why Choose Hand Sewing?

Hand sewing a hem is a good choice for:

A hem that looks neat and nearly invisible from the outside (like a blind hem).
Fabrics where tape or glue might show or not stick well.
A hem that needs to be strong and last a long time through washing and wearing.
When you want a more traditional finish.
If you enjoy hand crafts.

Materials Needed: Hemming Pants By Hand Needle Thread

Sewing needle (choose a size that is right for your fabric and thread)
Thread (match the color of your pants as closely as possible)
Scissors (fabric scissors and small thread scissors)
Measuring tape or ruler
Pins
Tailor’s chalk or fabric pen
Thimble (helpful to push the needle)
Iron and ironing board (for pressing folds)

Hand Sewing Stitches for Hems

You can use a few different stitches.

Running Stitch: Simple, fast stitch. Good for temporary hems or inside folds. Not very strong or hidden on the outside.
Blind Hem Stitch: Designed to be nearly invisible on the outside. Takes practice but gives a clean finish.
Hemming Stitch (or Slip Stitch): Also designed to be mostly hidden. Stronger than a running stitch for hems.

Let’s focus on the Hemming Stitch as it’s good for durability and is fairly easy to learn for permanent hems. We will also briefly cover the Running Stitch for a temporary hem solution.

Step-by-Step: Hemming Stitch (Mostly Hidden)

This method shows you hemming pants by hand needle thread for a clean, lasting hem.

Step 1: Prepare the Hem

Lay the pant leg inside out.
Find your finished hemline you marked.
Fold the fabric up along this line. Press the fold well with an iron.
Unfold the fabric.
Measure down from the finished hemline your hem allowance (1.5 to 2 inches). Mark this lower line.
Trim excess fabric below this line if needed.

Step 2: Create the Double Fold

Fold the raw edge of the fabric up to meet the finished hemline you marked earlier. Press this fold with an iron.
Now, fold the hem up a second time along the original finished hemline. The raw edge is now hidden inside the double fold.
Pin this double fold in place all around the pant leg. Place pins going vertically into the fold so they are easy to remove as you sew.

Step 3: Thread the Needle

Cut a piece of thread. About 24-30 inches is a good length. Too long threads tangle easily.
Thread the needle.
Tie a knot at the end of the thread. You can tie a small knot or a double knot.

Step 4: Start Sewing

Hide your knot inside the hem fold. Insert the needle into the folded edge of the hem, inside the fold, about 1/4 inch from the start of the hem. Pull the thread through until the knot catches inside the fold.
Bring the needle out of the top edge of the folded hem.
Now, take a tiny stitch in the pant fabric just above the folded hem edge. Pick up only one or two threads of the main pant fabric. The goal is to grab just enough fabric to hold the hem, but not so much that the stitch shows clearly on the outside.
Pull the thread through.

Step 5: Make Stitches

Move along the folded hem about 1/4 to 1/2 inch (about 0.5 to 1 cm) to the side.
Insert the needle into the folded hem edge again, right next to where you made the tiny stitch in the pant fabric. Go into the fold, move the needle inside the fold about 1/4 inch, and bring it out again near the top edge of the fold.
Take another tiny stitch in the main pant fabric just above where the needle came out of the fold.
Pull the thread through gently. Do not pull too tight, or the hem will pucker (gather up).
Keep making these stitches: a stitch along the fold, then a tiny stitch catching the main fabric above.
Keep the stitches evenly spaced.

Step 6: Finish Sewing

Sew all the way around the pant leg.
When you reach where you started, sew a few stitches over your first stitches.
To end, make a knot. Push the needle through the folded hem edge. Before pulling the thread all the way, put the needle through the loop of thread near the fabric. Do this two times to make a secure knot. Pull tight.
Cut the thread close to the knot, hiding the end inside the hem fold.
Repeat for the other pant leg.

Step-by-Step: Running Stitch (Temporary Hem Solution)

This is the easiest hand stitch. Use it when you need a very quick fix, like for a party, or when you know you will change the hem length later.

Step 1: Prepare a Single Fold

Lay the pant leg inside out.
Find your finished hemline.
Fold the fabric up along this line. Press the fold. You will have the raw edge inside the fold.
Pin the fold in place.

Step 2: Thread Needle

Cut a piece of thread. Thread the needle. Tie a knot at the end. Choose a thread color that is easy to see if it’s just a temporary hem, or match the fabric if you want it to be less visible.

Step 3: Sew the Stitch

Start by hiding the knot inside the fold.
Make simple, straight stitches up and down through both the folded hem and the main pant fabric, close to the top edge of the fold.
Push the needle down through both layers, then bring it back up a short distance away.
Make the stitches about 1/4 to 1/2 inch long, with spaces of about the same size between them.
This stitch will show on the outside, so keep that in mind.

Step 4: Finish

Sew all the way around.
Tie off the thread with a knot inside the hem fold.
Cut the thread.

Pros and Cons of Hand Sewing

Pros:

Can create a very neat, almost invisible hem (blind stitch).
Strong and durable when done correctly.
Works on most fabric types.
Can be taken out if you need to change the hem length later.
Gives a professional finish.

Cons:

Takes more time than no-sew methods.
Needs basic needle and thread skills.
Can be tiring for your hands on thick fabrics or long hems.
Must keep stitches even to look good.

Choosing the Best Method for Your Slacks

Which method should you use? Think about these things:

Your Skill Level: Can you handle a needle and thread? Or do you need the simplest, no-sew way?
How Fast You Need It: Iron-on tape and glue are faster than hand sewing.
How Long It Needs to Last: Hand sewing is usually the most durable. Iron-on tape and glue can come undone, especially after washing.
The Fabric Type: Very thin, sheer, or stretchy fabrics are hard for tape or glue. Hand sewing works better. Very thick fabrics can be hard to hand sew, but tape might not stick well either.
How You Want It to Look: Do you want a nearly invisible hem (hand sewn blind stitch) or is a quick, simple hem okay (tape, glue, or hand running stitch)?
Washing: Will the pants be washed often? Check if the tape or glue is washable. Hand sewing is generally safe for washing.

Here is a simple table to help you compare:

Method Comparison Table

Feature	Iron-On Hem Tape	Fabric Glue	Hand Sewing (Hemming Stitch)
Speed	Fast	Fast	Slow
Ease	Very Easy	Very Easy	Needs basic sewing skill
Durability	Moderate (can weaken with washing)	Low to Moderate (varies by glue)	High (durable)
Look	Smooth, but can be stiff	Can be stiff, might show if messy	Clean, can be nearly invisible
Fabric Types	Works on many, not ideal for thin/thick/stretchy	Works on many, can be stiff or soak through on thin/thick	Works on most fabrics
Temporary?	No, hard to remove	Depends on glue type	Yes, can be easily removed (running stitch)
Best For	Quick fixes, simple straight hems	Quick fixes, small spots, temporary	Durable, professional-looking hems

Tips for a Great Hem

No matter which method you pick, here are some extra tips to help you get the best result:

Wash the Pants First: Always wash the pants before hemming. Fabrics can shrink, and you want the hem to be the right length after shrinking.
Press, Press, Press: Use an iron to make sharp folds before you glue, tape, or sew. Sharp folds make the hem much easier to work with and look neater.
Use the Right Tools: Make sure your scissors are sharp. Use a needle that is right for your fabric thickness if hand sewing. Use quality hem tape or fabric glue.
Test First: If you are using hem tape or glue for the first time, or on a new fabric, test a small piece on a scrap of the same fabric. See how well it sticks and if it shows or makes the fabric stiff.
Be Patient: Don’t rush. Take your time measuring, marking, folding, and applying tape/glue or sewing stitches.
Hide Knots and Ends: If hand sewing, make sure your starting and ending knots are hidden inside the hem fold. Trim threads closely.
Care After Hemming: Check the care instructions for your hem tape or glue before washing the pants. Some might need gentle washing or air drying.

Taking Out a Temporary Hem

Sometimes you just need pants shorter for a short time, like for an event. Hand sewing with a running stitch is a great temporary hem solution because it’s easy to take out.

To remove a hand-sewn temporary hem:

Find the thread on the inside of the pant leg.
Use small scissors or a seam ripper to cut a few stitches.
Gently pull the thread. You might need to cut stitches every few inches as you pull.
Keep pulling and cutting until all the thread is out.
The hem will unfold.
Iron the area flat to remove the old fold lines.

For iron-on tape or fabric glue, removing a hem is much harder and can damage the fabric. This is why they are not ideal temporary solutions. Some special removers exist for glue, but they might not work perfectly.

Fabric Types and Hemming Without a Machine

The type of fabric your slacks are made from can affect which method works best.

Cotton and Cotton Blends: These are usually easy to work with. Hand sewing, tape, or glue can work well. Pressing folds is easy.
Wool Trousers: Thicker fabrics like wool are durable. Hand sewing is often the best for a long-lasting, invisible hem on wool. Iron-on tape needs to be heavy-duty for wool. Glue might not be strong enough. Wool can also be tricky to iron without a pressing cloth.
Synthetics (Polyester, Rayon): These can sometimes be slippery. Pressing helps make folds. Tape and glue can work, but test first as some synthetics can melt or react to glue. Hand sewing is a safe bet.
Silky or Very Thin Fabrics: These are hard to hem without a machine. Hand sewing with very fine needle and thread (like a blind stitch) is usually the best way to avoid puckers or visible tape/glue. Tape and glue can show through thin fabrics or make them stiff.
Stretch Fabrics: Fabrics with spandex can be tricky. Tape and glue might not stretch with the fabric, causing the hem to break. Hand sewing with a slightly loose stitch or using a stretch-specific iron-on tape might work, but this is one of the hardest fabric types for hemming without a machine.

Always consider the fabric before you start. If you are unsure, testing on a hidden spot or scrap is a good idea.

Caring for Your Hemmed Slacks

How you care for your slacks after hemming helps the hem last.

Washing: If you used iron-on tape or fabric glue, check the product’s instructions. Some need cold water washes or should not go in the dryer. Hand-sewn hems are usually fine with normal washing, but gentle cycles can extend the life of any garment.
Drying: High heat from a dryer can weaken the glue in iron-on tape or fabric glue. It’s often best to air dry pants hemmed this way, or use a low heat setting.
Ironing: Be careful when ironing over taped or glued hems. The heat could reactivate the glue. Iron from the inside if possible, and use a pressing cloth. Ironing hand-sewn hems is fine and helps them lay flat.
Check the Hem: Look at your hem after washing and wearing. If you see edges lifting with tape or glue, you might need to re-apply or touch up small areas. Hand-sewn hems might need a loose thread snipped off now and then.

Proper care makes sure your easy, no-sew, or hand-sewn hem stays put and looks good.

Frequently Asked Questions (FAQ)

Q: Can I hem jeans without a sewing machine?
A: Yes, you can use the same methods. However, jeans are thicker fabric. Iron-on tape needs to be very strong (“heavy duty”). Fabric glue might not hold well on the thick seam areas. Hand sewing is possible but requires a strong needle and might be hard on your hands. A blind hem stitch is often used for jeans to keep the original look.

Q: How much hem tape do I need?
A: Measure the distance around the bottom of one pant leg. You need twice that length of tape, as you will use it on both legs. It’s wise to buy a little extra, maybe a yard or meter more than you think you need.

Q: How long does fabric glue hem last?
A: This varies a lot based on the glue quality, the fabric, and how often you wash the pants. Some glues are meant for only temporary fixes and might come undone in the first wash. Others might last for several washes but are unlikely to be as permanent as a sewn hem. Check the product details on the glue bottle.

Q: Is a blind hem stitch hard to do by hand?
A: It takes practice to make the stitches small and even so they don’t show much on the outside. But the basic idea is simple: you catch only one or two threads of the main fabric with each stitch. There are many good guides and videos online that can help you learn the technique step by step.

Q: Can I use super glue to hem pants?
A: No! Do not use super glue or craft glue. These glues are not made for fabric. They will make the fabric hard, can damage it, will not hold up in the wash, and might even be unsafe chemicals for clothing. Only use fabric glue specifically made for clothing and hemming.

Q: What if my pants are lined?
A: If your pants have a lining, you will need to hem the lining separately after you hem the outer fabric. The lining hem should be about 1/2 inch (1-2 cm) shorter than the outer fabric hem. You can hem the lining by hand or use a thin iron-on tape.

Q: My hem tape didn’t stick. Why?
A: Make sure you used the right heat setting on your iron for the tape and fabric. Check if the iron was hot enough. Make sure you held the iron down firmly and long enough on each spot (10-15 seconds). Using a damp pressing cloth helps create steam, which activates some tapes better. Also, ensure the fabric was clean and free of starch or sizing that could block the glue.

Hemming slacks without a sewing machine is totally possible! Whether you choose the speed of iron-on hem tape for pants, the ease of fabric glue for hemming clothes, or the strong finish of hemming trousers by hand step by step, you have good options. Pick the method that fits your needs, gather your materials, and take your time for a great result. You can easily give your pants a quick hem without sewing machine hassle.
