How to Calculate an Elastic Waist Measurement
Use a tape measure to calculate elastic waist measurements. (NA/ Images)

Garments with an elasticated waist allow for more comfortable wearing as the elastic gives with movement without digging into the flesh. Making garments with an elasticated waist is also easier than making them with a fitted waist, as there is no need for buttons or zippers. The elastic in a waistband needs to fit correctly for maximum comfort, as well as to hold the garment in place without sagging or pulling.

  1. 1

    Measure around the waist holding the tape measure against the skin, not over clothing. Keep the tape measure snug against the skin, but don't pull it tight.

  2. 2

    Double the seam allowance and add to the measurement if the elastic will be sewn into a seam. If you intend threading the elastic through a waistband hem, add one inch to the waist measurement to allow you to overlap the elastic ends when you sew them together.

  3. 3

    Cut the elastic to this measurement, then try it around the waist for fit, remembering to pinch the seam allowance between your fingers to hold the elastic ends together, as this allowance will disappear when the elastic is attached to the garment. The elastic should feel snug around your waist, and tight enough to stay in place without digging in.
