1. Put tape on back of your neck to start measuring

Put the end of the tape at the base of the neck on your back where the top of your t-shirt would be.

2. For a tucked in shirt

Run the tape measure to the top of your crotch for a tucked-in shirt. You need the shirt to be a little longer if you plan to tuck it in all the time. Hold the tape measure straight down from your shoulders; don’t follow your spine. Mark the measurement that’s just below your butt.

3. For an un-tucked shirt

Take a slightly shorter measurement for an un-tucked shirt. Run the tape measure down from your shoulders without bending in for your spine. Find the spot where you want your shirt to fall, and write down that measurement.

  • It’s hard to do this measurement yourself, as it runs down your back. It will be easier to have someone else measure to get an accurate measurement.
  • If you’re wearing a collared shirt, start at the bottom of the collar instead.
  • Grab a friend to help.


The body length for a shirt is measure from the base of the neck (shirt neck line) down to where you want the shirt to end. Usually sitting between the top of your buttocks and the bottom of your cheeks, depending on the type of shirt and your style.

Your torso length is the length between the base of your neck and top of your hip bone. The length of your torso usually is the same as someone else the same height as you, worldwide.

Slide both of your hands down the ribcage to the top of your hip bones (aka the iliac crest). With index fingers pointing forward and thumbs pointing backward, draw an imaginary line between your thumbs. This spot on your lumbar is the bottom of your torso measurement.
