Step 1
Determine what type of fabric it is, so that you can determine how thick it is. The thickness of the fabric determines how to estimate the yardage. This is just an estimation process, but you won’t get an accurate estimation without knowing about how thick the fabric is.

Step 2
This will give you a good guide for determining the thickness of fabrics. Generally speaking chiffon, lace, and tulle will require 3 wraps around the bolt to equal one yard of fabric. Heavy weight fabrics such as velvet, cottons, satins, and jean fabrics will require just two wraps around the bolt.
So you’re ready to start estimating, eh? Start out by taking a bolt of fabric. Inspect the bolt, look how the fabric wraps around it several times. A fabric that is thin will require a bit more wraps or layers to equal one yard, and a fabric that is half an inch in thickness would require two wraps around the bolt to equal one yard of fabric. So the trick to this is to estimate how thick the fabric is, and always buy a little more than you need. It’s always best to overbuy than to not have enough, rush to the store and then find they’ve sold out. -
Step 3
Take a look at my photo # 2; the picture contains five yards of fabric, and pictures a thin and sheer fabric such as chiffon. The yardage was determined by counting a yard for every three layers of fabric because of thinness of the fabric. Notice my finger holding three layers? This signals one yard of fabric. You can see from the photo that I separated the layers so it is easier to see. For thicker fabrics such as velvet, jean materials, cottons, or satin it is best to stay with two wraps for every one yard of fabric.

Step 4
Try and do estimation by yourself. Take a bolt of fabric, determine the thickness of the fabric, and count the layers it holds. Remember that for thicker fabrics it’s every two wraps for one yard of fabric, and for thin fabrics it’s every three wraps for one yard of fabric.
