There are several reasons fabric needs to be squared before cutting into it. When fabric is printed and placed on a bolt, it can become stretched. The ends may fray during shipping and handling. Staff at the fabric store may not cut it perfectly straight when measuring yardage off the bolt.

Materials to Square Up Fabric

How to Square Up Fabric Before Cutting

You will need the fabric of your choice, and a few basic sewing supplies: a rotary cutter, self healing cutting mat, and acrylic ruler.

If you don’t already have these supplies, go ahead and invest in them. You will use them in a myriad of ways for every future sewing project.

How to Square Up Fabric

First, wash, dry and press your fabric. This is important, as fabric can shrink and shift during the washing process. Pressing helps the fabric to lay flat so that your cut lines are precisely straight. Know what your fabric is going to do when laundered before using it in a project.

 Then pick up your fabric by one selvage edge. (See photo for raw edge and selvage examples.) The selvages are woven ends of the fabric created by the manufacturer. These lines are already straight and provide a good guideline to square up the fabric. *Selvage can become warped during washing.

The photo above shows the selvage edge. It typically has writing and information about the fabric on it.

Next bring the other selvage end up to the first edge. You can do the next part while holding the fabric in your hands – it’s easier than laying it flat.

Now slide the selvage ends along each other side to side until the rest of the fabric hanging below seems to be straight with no folds or bumps. You can lay the fabric flat to check this. You will end up with unevenly cut raw edges on the sides.

Once the fabric seems flat, slide a cutting mat underneath. Line the selvage ends up with a straight line on the cutting mat. The folded edge and the selvage edges should line up to parallel straight lines on the cutting mat. *Line up the folded edge with the mat. This is the true line, rather than selvage edge.

For this part, I am right handed, so this makes more sense to me. Left handed folks will do the opposite! Take the left side raw edges and fold carefully on top of the fabric so that all the raw edges are on the right side. The fold and selvage ends should stay lined up.

Now using a clear ruler, find the point in the fabric that is just past the raw edges to the left.

The bottom and right edge should form a 90 degree angle at the bottom right corner.

Cut a clean line using your rotary cutter and ruler.

Keep your fingers at least half an inch away from the edge of the ruler. Hold the ruler and fabric steady with consistent pressure while cutting. Make sure the blade in your rotary cutter is sharp.

  1. Hi Brenda! The selvage edge and the edge that runs parallel to it do not need to be cut. They are already straight.

  2. So glad someone has finally posted how to straighten your fabric (the correct way) before cutting. This is the method I was taught 25 years ago, but have never seen anyone who has done it this way on the internet. I do disagree about cutting on the right side. I teach it takes 2 rulers to make that straightening cut on the right side. I teach that the right handed cut from the left, and lefties cut on the right. I could send pictures if you want.

  3. Interesting! I’ll give your method a try and update the post. Thanks for commenting, Charlcie!

  4. You have “squared” the ends with the sides, which is okay for most small, flat projects. But it would be good if you clarified this, and included a link for straightening the grain, as this is necessary when making garments or anything that hangs such as draperies, tablecloths, etc.

  5. To put fabric on the grain I was taught to pull a thread in the fabric until a line gets all the way across. Then cut across that line. This is on raw edge of fabric. Pick it up and if not even, take opposite ends an stretch until it is. This how I square fabric up.

  6. How do you square up fabric that has no salvage? I have inherited a wide variety of smaller pieces which have been cut before I received them. Also is it important to square up fabric if you are cutting pieces for a small quilt project?

  7. I have read your article and comments. I, too, was taught to pull a thread on
    The raw side of the fabric back in home economics. Do they even teach sewing in high school anymore? My mother also taught me to snip a small cut on the raw edge (after washing) then rip the fabric from one raw edge to the other. This will give you a true 90 degree angle where the raw and selvage edges meet. Please let me know your thoughts.
