Using Math: Generally, elastic is stretched between 3-8%, with 8% being used only in parts where you want the garment to “hug” the body (i.e. at the underarm near the armpit). So if you want to use math, then you can measure the length of what is being sewn and reduce it by 5%.
Do you stretch elastic when sewing?
Make sure to stretch the elastic out as you sew so that it will be the same length as the fabric. Sew all the way around the elastic and overlap the beginning of the stitching slightly when you have sewn all the way around the elastic.
How many inches does elastic stretch?
Although elastic comes in several widths, you’ll probably want the elastic to be between 3⁄4 to 1 inch (1.9 to 2.5 cm) wide. Keep in mind that the width will vary depending on whether you’re sewing it directly onto the fabric or into casing.
What tension should I use for elastic?
Generally elastic works best when stretched 3-8%, with 8% only being used on the smaller parts of the garment as it’s a bit extreme, as remember the more you stretch the elastic the more stitches you are putting on that space of elastic.
How is stretch of elastic measured?
You’d subtract 25 to 40 percent of what you want the finished area to measure, from the elastic. For example, if you have a stretch pant and want the waist to fit a 30″ waist, subtracting 25% from 30″ equals the length of your elastic (25% of 30″ = 7.5″.
Can you cut elastic in half lengthwise?
It is possible to cut woven elastic but it is not advisable to cut it lengthwise. When you cut this type of elastic in the normal way, it works well, is very firm, and maintains its width. But if you cut the material lengthwise you can expect fraying to take place.

How do you calculate elastic for a fitted sheet?
