Armhole length

measuring length of armhole

The armhole length is the total length of the front and back armholes. An easy way of taking this measurement, is to match your patterns at the side seam (or shoulder seam if you prefer), and then measure the total length of the armhole. If your pattern has seam allowance, be sure to match the two pattern pieces together as if they have already been sewn (by lining up 'stitch line' with 'stitch line').

If your pattern has seam allowance, be sure to measure along STITCH LINE and not along edge of the pattern, when determining the length of the armhole.
