You set the tension on a Brother sewing machine mainly by turning the thread tension dial on the front of the machine. This controls the tension of the upper thread. Getting the tension right is key to making good stitches. When the tension is right, the stitches look the same on the top and the bottom of the fabric. This guide will show you how to do this and fix common issues like Brother sewing machine thread tension problems.

Knowing About Sewing Machine Tension
Good sewing needs good tension. Tension is like a pull on the thread. Your machine has two threads working together. One comes from the needle (upper thread). The other comes from the bobbin (bobbin thread).
When the tension is right, the two threads lock together in the middle of the fabric layers. This makes stitches that look neat and strong on both sides. If the tension is off, the stitches look bad. They might loop, look loose, or pull the fabric.
Why Tension Matters for Your Sewing
The right tension makes your projects look nice and last longer.
– Strong stitches: Good tension makes stitches that hold fabric together well.
– Neat look: Stitches look flat and even. No loops or puckers.
– Fabric care: Correct tension does not pull or damage the fabric.
– Machine works well: Your machine runs smoother with the right tension.
Where to Find Tension Controls
Your Brother machine has places to change tension.
– The main one is the thread tension dial. This is usually a dial with numbers on the front of the machine. It changes the pull on the upper thread.
– The bobbin case also has a tension control. This is usually a small screw on the bobbin case itself. It changes the pull on the bobbin thread. You change this one less often.
Getting Ready to Check Tension
Before you change tension, do these simple checks. They can often fix Brother sewing machine thread tension problems without touching the dial.
– Is the machine threaded right? Make sure both the upper thread and the bobbin thread are put in the machine exactly as the manual says.
– Is the presser foot down? The upper tension only works when the presser foot is down.
– Is the right needle in? Use a needle that fits your fabric and thread size. A bent or wrong needle causes problems.
– Is the bobbin wound well? The bobbin thread should be smooth and even, not too tight or too loose.
– Is the machine clean? Lint and thread bits can get in the tension parts and mess things up. Clean your machine often.
– Are you using the right thread? Use good quality thread. Both the upper and bobbin thread should be the same kind and weight if possible.
Figuring Out What Good Tension Looks Like
You need to sew a test piece to see the tension.
1. Take two pieces of the fabric you plan to use.
2. Use the same thread you will use for your project.
3. Set your machine to a basic straight stitch.
4. Sew a line of stitches on the test fabric.
5. Look closely at the stitches on the top and bottom of the fabric.
What perfect tension looks like:
– On the top: Straight stitches, no loops. The bobbin thread is pulled slightly into the fabric.
– On the bottom: Straight stitches, no loops. The upper thread is pulled slightly into the fabric.
– In the middle: The threads meet and lock inside the fabric layers. They do not lie flat on top or bottom.
Solving Common Brother Sewing Machine Thread Tension Problems
Sewing machine tension issues on a Brother machine often look a certain way. Knowing these looks helps you figure out what to adjust.
Looping Stitches on Bottom of Fabric Brother Machine
This is a very common problem. It means the upper thread is too loose. It is not being pulled down enough to meet the bobbin thread inside the fabric. Instead, it forms loops on the underside.
What it looks like:
– Top side: Stitches might look fine or a bit tight.
– Bottom side: Big loops of thread sit on the fabric.
What is wrong: The upper thread tension is too low.
How to fix it: Increase the upper thread tension adjustment on your Brother machine. Turn the thread tension dial to a higher number. Go up one number at a time. Test after each change.
Possible other reasons:
– Upper thread not in the tension discs right. Re-thread the machine carefully with the presser foot up.
– Presser foot is up while sewing. Always sew with the presser foot down.
– Bobbin tension is too high. This pulls the loose upper thread into loops on the bottom. This is less common but can happen. Check bobbin tension if increasing upper tension does not work.
Looping Stitches on Top of Fabric Brother Machine
This is the opposite problem. It means the bobbin thread is too loose, or the upper thread is too tight. The upper thread pulls the loose bobbin thread up to the top.
What it looks like:
– Top side: Big loops of thread sit on the fabric.
– Bottom side: Stitches might look fine or a bit tight.
What is wrong: The bobbin tension is too low, or the upper tension is too high.
How to fix it:
1. First, try lowering the upper thread tension adjustment on your Brother machine. Turn the thread tension dial to a lower number. Go down one number at a time. Test after each change.
2. If that does not fix it, the bobbin tension might be too loose. You might need bobbin tension adjustment on your Brother sewing machine. This is trickier and explained later.
Possible other reasons:
– Bobbin wound too loosely. Rewind the bobbin tightly and evenly.
– Bobbin not put in the case or machine correctly. Check your manual.
Fixing Loose Stitches Brother Sewing Machine
Loose stitches happen when both threads are not pulling enough. The stitch looks flat on both sides of the fabric. The threads do not meet in the middle. The seam is weak.
What it looks like:
– Top side: Stitches look flat on the fabric.
– Bottom side: Stitches look flat on the fabric.
– You can easily pull the layers of fabric apart.
What is wrong: Both upper and bobbin tension are too low.
How to fix it: Increase both tensions a little bit. Start by increasing the upper thread tension adjustment on your Brother machine using the thread tension dial. If stitches are still loose, you might need to slightly increase bobbin tension (carefully!).
Possible other reasons:
– Using thread that is too thin for the fabric.
Correcting Uneven Tension Brother Machine
Uneven tension means the stitches look different along the seam or on different parts of your project. One side might look good, the other might loop or be loose.
What it looks like:
– Stitches change look as you sew.
– Stitches look different on curves than on straight lines.
What is wrong:
– Thread snagging somewhere.
– Lint or dirt in tension parts.
– Uneven bobbin winding.
– Machine needs cleaning or oiling.
How to fix it:
– Re-thread both upper and bobbin thread carefully. Make sure thread moves freely.
– Clean out the tension discs and bobbin area well. Use a brush or air.
– Rewind the bobbin carefully and evenly.
– Check thread path for any snags or twists.
– Clean and oil your machine according to the manual.
Adjusting Upper Thread Tension on Your Brother Machine
This is the first thing to adjust when you have tension problems. It is the most common fix.
h4 The Thread Tension Dial
Your Brother machine has a dial or buttons for upper thread tension.
– Dials: These have numbers, often from 0 to 9 or more. A lower number means less tension (looser thread). A higher number means more tension (tighter thread). The usual setting is around 3, 4, or 5. This is your “sew machine tension guide Brother” start point.
– Buttons (on some digital machines): You press plus (+) or minus (-) buttons to change the number on a screen. Higher number is more tension.
h4 Steps to Adjust Upper Tension
- Sew a test piece of fabric. Look at the stitches.
- Do you have looping on the bottom? This means upper tension is too loose. Turn the thread tension dial to a higher number.
- Do you have looping on the top? This means upper tension is too tight (or bobbin is too loose). Turn the thread tension dial to a lower number.
- Change the number by just one at a time.
- Sew another test piece after each change.
- Keep adjusting and testing until the stitches look right on both sides. The threads should meet in the middle of the fabric layers.
h4 Tips for Upper Tension Adjustment
- Always test on the fabric you are using for your project. Different fabrics need different tensions.
- Different threads also need different tensions. Thicker thread needs less tension.
- Make small changes. One number makes a difference.
- Write down the tension setting that works for certain fabrics and threads. This is a good sew machine tension guide Brother tip.
Bobbin Tension Adjustment Brother Sewing Machine
Adjusting bobbin tension is less common. Brother machines are made so you usually only need to change the upper tension. You should only adjust bobbin tension if:
– You have tried adjusting the upper tension fully and still have problems (especially looping on the top that lowering upper tension does not fix).
– You are using very special thread that needs it.
– Your machine manual tells you to.
Warning: The screw on the bobbin case is small. It is easy to over-adjust or lose the screw. Mark the starting position of the screw before you touch it. This way, you can always go back to the original setting.
h4 How to Check Bobbin Tension (The “Drop Test”)
This test helps you see the bobbin tension without sewing.
1. Take the bobbin case out of the machine.
2. Put the bobbin in the case. Let about 4-6 inches of thread hang out.
3. Hold the bobbin case by the thread. Just hold the thread end in your hand.
4. The bobbin case should hang from the thread.
5. Give the thread a small, gentle tug or jerk.
6. The bobbin case should slowly lower itself a little bit, maybe an inch or two. It should not drop freely.
7. If it drops freely, tension is too loose.
8. If it does not move at all, tension is too tight.
h4 Steps to Adjust Bobbin Tension
You need a small screwdriver that fits the tiny screw on the bobbin case.
1. Find the small screw on the side of the bobbin case. There is usually only one that changes tension.
2. Before you touch it, look closely at the screw slot. Use a marker or pen to draw a tiny line from the slot onto the bobbin case. This marks the starting point.
3. To increase bobbin tension (if tension is too loose): Turn the screw a very small amount clockwise. Think “righty tighty”. Start with turning just as much as a number on a clock face (like from 12 to 1).
4. To decrease bobbin tension (if tension is too tight): Turn the screw a very small amount counter-clockwise. Think “lefty loosey”. Again, turn just a tiny bit.
5. Put the bobbin case back in the machine. Thread the machine.
6. Sew a test piece.
7. Check the stitches. If needed, take the bobbin case out and adjust the screw another tiny amount.
8. Keep adjusting and testing until the stitches look right, or the drop test works well.
h4 When Bobbin Tension is Factory Set
Many newer Brother machines have a bobbin case that is set at the factory. The manual might tell you not to adjust it. If you have problems and the upper tension is right, it might be a problem with the bobbin case itself or lint inside it, not the setting. Try cleaning the bobbin case area well. If problems continue, you might need to see a repair person.
Troubleshooting Sewing Machine Tension Issues Brother
Sometimes, adjusting the tension dial is not enough. If you are still having Brother sewing machine thread tension problems, think through these steps.
h4 Common Causes Beyond the Dial
- Wrong threading: This is the #1 cause of tension problems. Take both threads out. Re-thread everything from the start, following your manual exactly. Make sure the presser foot is UP when threading the upper thread so the thread goes fully into the tension discs.
- Dirty machine: Lint, thread scraps, or oil buildup can block the thread path or tension discs.
- Clean the upper tension discs: Thread the machine with a piece of dental floss or strong thread. With the presser foot down, slide the floss back and forth in the tension slot. This pulls out lint.
- Clean the bobbin area: Remove the bobbin, bobbin case, and needle plate. Use a brush to remove all lint. Do not use canned air as it can push lint deeper.
- Damaged needle: A bent, dull, or wrong-size needle can mess up stitches and tension. Put in a brand new needle. Make sure it is put in the right way.
- Bad thread: Old thread, cheap thread, or thread with slubs (thicker spots) can cause tension issues. Use good quality thread. Check if the thread is getting caught on the spool.
- Wrong bobbin: Make sure you are using the right type of bobbin for your Brother machine. Using the wrong bobbin can cause many problems.
- Machine needs service: If you have tried everything and the tension is still bad, your machine might need cleaning, oiling, or repair by a professional.
h4 Step-by-Step Troubleshooting
If your stitches look bad:
1. Stop sewing. Do not keep going or it might make it worse.
2. Look at the stitches. Are the loops on the top or bottom? Are stitches loose? This tells you where to start. (Looping on bottom = upper tension too loose. Looping on top = upper tension too tight or bobbin too loose. Loose stitches = both tensions maybe too loose.)
3. Re-thread the entire machine. Both upper and bobbin. This fixes many problems. Make sure the presser foot is up when threading the upper thread.
4. Put in a new needle. Use the right type and size for your fabric.
5. Clean the machine, especially the upper tension area and the bobbin case area.
6. Sew a test piece on your project fabric.
7. If stitches are still bad, adjust the upper thread tension dial. Turn it one number up for loops on the bottom. Turn it one number down for loops on the top. Sew and test again.
8. Repeat step 7 until the stitches improve or the problem changes.
9. If upper tension changes do not fix looping on the top, and you are sure about steps 1-6, you might need to look at bobbin tension (carefully!). Mark the screw first!
10. If nothing works, check your manual for specific troubleshooting for your model. Or, take your machine to a repair shop.
h4 Using a Sew Machine Tension Guide Brother Chart
Some fabric and thread combinations work best with certain tension settings. Your manual might have a chart, or you can make your own.
| Fabric Type | Thread Type | Suggested Upper Tension Start (Example) | Notes |
|---|---|---|---|
| Quilting Cotton | All-purpose poly | 4 | Standard setting, usually works well. |
| Light Rayon | Fine poly/cotton | 3 | Lighter fabric needs less pull. |
| Denim | Strong poly | 5-6 | Thicker fabric needs more pull. |
| Knit Fabric | Poly or stretch | 3-4 | Need a little stretch in stitches. |
| Silk | Fine thread | 2-3 | Very light fabric needs very little pull. |
This table is just an example. You should always test on scraps of your actual fabric. Your best sew machine tension guide Brother is your test stitching.
Different Brother Machines and Tension
Brother makes many types of sewing machines.
– Simple mechanical machines have a clear tension dial you turn.
– Electronic machines might have a digital display and buttons for tension.
– More advanced machines might even have automatic tension settings. But even with auto tension, you might sometimes need to make small changes.
Always check your specific Brother machine manual. It will show you exactly where the tension controls are and how to use them.
Sew Machine Tension Guide Brother: Best Practices
- Always test: Never start sewing your project without testing tension on a scrap piece of the same fabric.
- Small changes: Adjust tension by just one number at a time.
- Know what to expect: Look at what good stitches should look like on your fabric.
- Re-thread first: When in doubt about tension, re-thread the whole machine.
- Clean often: Keep your machine free of lint and dirt.
- Use quality supplies: Good thread, needles, and bobbins prevent many problems.
Practicing Your Tension Adjustment Skills
Learning to set tension takes practice. Sew lines of stitches on different fabrics using different threads. Look closely at the stitches. Change the tension dial and see how it changes the stitches. This helps you learn how to set tension on your Brother sewing machine by eye.
Try these practice steps:
1. Take a piece of medium-weight cotton. Set upper tension to 4. Sew a line. Look at it.
2. Change tension to 2. Sew another line. How do the stitches look now? (Likely looping on the bottom).
3. Change tension to 6. Sew another line. How do the stitches look? (Likely pulling fabric or looping on top).
4. Now try to get back to the perfect tension by adjusting.
5. Do this with different fabrics (light cotton, denim, knit). See how the perfect setting changes.
This kind of practice builds your skill in correcting uneven tension Brother machines can sometimes have, or just getting perfect stitches every time.
When Bobbin Tension is NOT the Problem
Remember, most Brother sewing machine thread tension problems are fixed by adjusting the upper tension dial or re-threading correctly. Bobbin tension adjustment on a Brother sewing machine is rarely needed for basic sewing.
If you have looping on top even after lowering upper tension as much as possible, and you’ve re-threaded and cleaned, the issue could be:
– The bobbin case itself is damaged.
– There is lint packed under the tension spring on the bobbin case. This is hard to clean yourself without taking the screw off.
– The upper thread is catching somewhere before it gets to the tension discs. Check the thread path above the needle.
Summary: How to Set Tension on Brother Sewing Machine
- Thread machine correctly with presser foot up for upper thread.
- Sew test stitches on your project fabric.
- Look at the bottom stitches: Loops mean upper tension is too loose. Turn upper tension dial UP.
- Look at the top stitches: Loops mean upper tension is too tight (or bobbin is loose). Turn upper tension dial DOWN.
- Look at both sides: Stitches are flat and loose? Turn upper tension dial UP. (Maybe bobbin tension also needed, but try upper first).
- Make small adjustments (one number).
- Test again after each change.
- Only adjust bobbin tension carefully and as a last resort, marking the screw position first.
- Clean machine and re-thread if adjustments don’t fix the problem.
FAQ: Brother Sewing Machine Tension
h5 Q: What is the normal tension setting on a Brother sewing machine?
A: The most common setting is usually between 3 and 5 on the upper thread tension dial. However, the best setting depends on your fabric and thread. Always test to find the right one.
h5 Q: Why are my stitches looping on the bottom?
A: Looping stitches on bottom of fabric on a Brother machine almost always means your upper thread tension is too loose. Increase the upper thread tension number on the dial. Make sure you threaded the machine correctly with the presser foot up.
h5 Q: Why are my stitches looping on the top?
A: Looping stitches on top usually means the upper thread tension is too tight, or the bobbin thread tension is too loose. First, try decreasing the upper thread tension using the dial. If that doesn’t work after re-threading and cleaning, the bobbin tension might be too loose.
h5 Q: Should I adjust bobbin tension?
A: You usually do not need bobbin tension adjustment on a Brother sewing machine for normal sewing. Adjust the upper thread tension first. Only adjust bobbin tension if your manual says so or if you cannot fix severe looping on top after trying everything else. Adjust the bobbin screw very, very slightly and mark the original position first.
h5 Q: How do I know if my tension is perfect?
A: Sew a test seam on your project fabric. Stitches should look the same on the top and bottom, with no loops. The threads should lock together inside the fabric layers.
h5 Q: What if adjusting tension doesn’t fix my stitch problems?
A: If you are still having troubleshooting sewing machine tension issues Brother after adjusting, check other things. Re-thread the entire machine, put in a new needle, and clean out lint from the tension discs and bobbin area.
h5 Q: Can different types of thread cause tension problems?
A: Yes. Thicker or thinner threads, slippery threads, or old/poor quality threads can affect tension. Use good quality thread. You may need to adjust tension slightly for different threads.
h5 Q: Why is my fabric puckering?
A: Fabric puckering can be caused by tension that is too tight (usually upper tension). It pulls the fabric as you sew. Try lowering the upper tension. Using the right needle for your fabric also helps prevent puckering.
Adjusting the tension on your Brother sewing machine is a basic but very important skill. By understanding how the upper and bobbin tension work and following these steps for troubleshooting sewing machine tension issues Brother, you can fix most stitch problems and make your sewing look professional. Always test on scrap fabric and make small changes!
