How to Make a Pants Pattern

Updated February 21, 2017

Are you in the market for a new pair of trousers, but can't seem to find a pair that fits right and is affordable? Why not make your own trousers? Making a pair of trousers is easy. It all starts with having the right trousers pattern. If you already own a pair of trousers with the perfect fit, and you have some sewing skills, you can fabricate a trousers pattern that will produce the perfect pair of trousers for you.

Make your very own trousers pattern using an existing pair of trousers. If you have a pair of trousers that fit perfect, yet they are about to fall apart, take them apart and use the pieces for your trousers pattern.

Use a seam ripper to take apart the pair of trousers. Do not attempt to tear apart the seams on clothing without a seam ripper. It is a handy little tool that cuts right through the threads on any garment. Using your seam ripper, take your trousers apart at the seams.

Lay the parts on large sheets of paper. Attach the trousers parts to the paper using straight pins.

Trace the trousers parts onto the paper with a pencil. Once you have traced all the parts, cut out each part of the trousers using a sharp pair of scissors.

Remove the straight pins, putting them back into the pin cushion, and set the fabric trousers parts aside. The paper cutouts of your trousers parts is now your new trousers pattern. This is what you will use when creating your pair of trousers.


Because you are making your own trousers pattern, try adding a zipper to an elastic waisted pair of trousers, or hem the trousers legs up into a pair of knee trousers. You are creating your own pattern, so you can create your trousers to look any way you desire. The great thing about using an existing pair of trousers to create a trousers pattern is that you already know the trousers will fit.


When using a seam ripper, be careful not to cut away from the seam. If you are in a hurry, and you are cutting too fast, your seam ripper can slip and cut into the actual trousers. If you are not planning on sewing the trousers back together for reuse, it's probably OK to make a slip, but still try to be careful. If you take good care of the trousers you just disassembled, you can use them again in the future if need be.
