Elastic Length Calculator
Waistband elastic is a little shorter than the waist, so it holds the garment up. This gives the cut length, with an overlap for the join.

How it works
Subtract the amount you want the elastic to be shorter than the waist. That is the length the elastic should reach around.
Add the overlap for the join, so the elastic can be sewn into a loop.
Worked example
For a waist of 32 in, with the elastic 2 in shorter and an overlap of 1 in, cut the elastic to 31 in.
Questions
How much shorter than my waist?
Many sewing guides suggest about 2 inches, or 5 cm, but the right amount depends on how snug you want the waistband and on the type of elastic.
Should I measure the elastic stretched?
No. Cut it at its relaxed length, and keep the shorter amount in mind for comfort.
Why add an overlap?
The ends are sewn together, and the overlap keeps the join from coming loose. Use a little more for a wider elastic.
