How to Adjust Tension on Your Sewing Machine: a Step by Step Guide 2021

5 min

Classic sewing machines in many work situations, but they can go wrong. Sometimes they can be dangerous, sometimes they fit together perfectly, but finding the second option is sometimes quite difficult. Usually, sowers are relatively afraid to fix problems such as thread build-up or adjusting the tensions, because something can go very wrong even when they are at work. When the tensions , both sides of the stitching look the same with no differences. There are, of course, many other effects and if you are here to understand tension fixation, I recommend you read on to find out how to adjust the tension on the sewing machine.

What is the tension of a sewing machine?

The tension of a sewing machine is one of the most essential parts of the sewing machine. If we turned the sewing machine tension off, the thread will be wrong, whether it is part of the work procedure such as weaving, if the tension is wrong on both the top and bottom of the thread. There are many problems with the sewing machine tension, but knowing how to fix them is a must.

Basically the tension makes both sides of the thread equal to avoid extra spool or thread the side it should not be on. Tension works through pressure on the wire, which can work if the tension is correct for that length of wire. The tension can and when adjusting there is usually a dial that makes it easy to fix it.

Know if your tension is a problem:

Adjust the sewing machine tension should happen after a while with everyone’s beloved machines, but when is it time to adjust the setting? Good question, there are plenty of situations where stress is likely to be the problem which we will discuss below. Just remember, if nothing is wrong, don’t change it and also test a spare piece of fabric for the new tension, if you need one.

A situation of tension can be the problem is when the stitching is not equal on both sides. The height of the thread may differ on one side from the other or the pattern. You can easily tell if either side is uneven when you look at a piece of fabric, if not, it’s time for a unique setting. Also, the bobbin can on top of the side being sewn, showing an inconsistency in the tension. Also top thread can be visible on the underside of the visible side, the side is thread because all the bobbin thread is on the other side.

Check the following before changing the voltage:

What is a sewing machine tension?

  • The size of the needle, threads and fabric can all contribute to a tension change during bobbin winding, which can also result in loops of the thread. Needles that are too large or too small for the thread can affect total Peak tension used. I can notice this when creases appear when sewing thin fabrics. In this situation, try using a straight stitch presser foot and a needle plate as a replacement and as a last resort before changing the tension.
  • Make sure they connect the right presser foot to your machine, so the technique is correct too.
  • Dirty machines are one of the principal causes of power problems. Examples of dirty machines are wire trapped between tension discs and virtually anywhere that wire can get caught, such as under the throat plate, around the spool house and wherever. When this happens, it is best to use floss in the tension discs of the machine. I can do this with a thin lightweight object. If there is still a tension problem, I recommend you continue reading how to adjust the tension on the sewing machine.
  • Machine parts can become damaged over time, which is likely to affect the tension of the sewing machine. Anything from half-broken needles, broken bobbing, broken tension discs, anything on the machine can lead to a change in tension. It can lower easily metal bobbins and you don’t have to adjust them. Put the coil away immediately, as the smallest dent, bend or other damage can lead to a change in tension.
  • You may have threaded the machine incorrectly. Use different thread guides, as this can deform the tension or cause loops in the thread even after the slightest mistake. Also, make sure the bobbin has no chance of slipping by making sure they always lower the presser foot while sewing. Other threading mistakes include misplacing the bobbin, not using a bobbin spool, the thread keeps changing shape, or the thread remains on the spool bobbin.

Clamping Tools:

Tension tools:

The Three Main tensioning tools you will need are the tensioning mechanism, thread guide, and bobbin case spring. You need to know all three before learning how to adjust the tension on the sewing machine.

Voltage Assembly comprises both voltage disks and voltage regulators. Voltage regulators are important because they control the amount of pressure applied to the wire, which must if you need to change the setting. When the regulator is in the machine, there must be an electrical system that controls it. The tension disc pinches the thread so that it stays in a straight line. A control panel usually controlled the drive on the front of the machine; this means they can sometimes control 2 wires at the same time.

Wire guides are used to guide the wire in a particular direction. There are many thread guides in a sewing machine, and they exert resistance on the thread, which is besides the resistance exerted by the tension discs.

Finally, the bobbin case spring is used to apply pressure to the thread that soon as it comes loose from the bobbin case. A small screw controls the amount of pressure that is on the back of the spring. They need the screw to increase tension and decrease tension, by turning the screw left and right.

Adjust the tension:

Adjusting the tension:

Now what you probably need to know is how to adjust the tension on the sewing machine To adjust. This is actually very easy once you know it. Think of it like a tug of war, both sides should be even and the top should show only top thread, while the bottom should show only bobbing thread.

In case needle thread is visible at the bottom of the thread, you must raise the upper thread by tightening it. To do this, you need to find the tension change dial, which you can find in the sewing machine manual as it varies by model. Next, you need to increase the tension by tightening the thread, which you can do by increasing the number on the button. Keep testing it until both sides are equal again.

If bulge is visible in the top thread, it will need to be loosened. Find the control knob again and this time pull down the wire numbers. Continue to practice sewing until both sides are equal, at this point there is perfect tension.

If neither works resort to replacing the bobbin case spring. However, this should only be the case if using a heavier or lighter wire than what . If the thread is heavier than normal, it will require a higher tension. To do this, increase the number of the dial until both sides are equal. If the thread is lighter than usual, it will require a lower tension, so use a lower number on the dial and keep testing until both sides of the thread are even.


Even if you use the best sewing machine out there, eventually you will be voltage problem. It could just be a simple cause that is the problem, such as loops in the wire. Often, adjusting the tension can . But when it , we must do correctly it. Knowing when to turn the tension up or down is an important part of a big sower, so make sure you know how to do it. Otherwise, problems will arise with the clothing or fabric you make.
