Inseam

Inseam is the length of the leg along its inside: on the body, from the crotch to the floor without shoes; on pants, from the crotch seam to the hem. In a pant size like "32/32" or "W32 L32", the second number is the inseam in inches.

How to measure

1. Take off your shoes and stand on a hard floor, feet slightly apart.
2. Hold a hardcover book level between your legs, spine up, touching the crotch.
3. Measure from the top of the spine straight down to the floor.
4. Or lay pants that fit flat and measure the inside seam, from where the four seams meet to the hem.

The template step: "from the crotch to the floor along the inside of the leg, without shoes."

On a size chart

Inseam is a length, one value per size, sometimes the same for all:

The tall scrubs inseam is 8 cm longer in every size: a length option, not another size. The outseam runs down the outside instead and includes the rise.

In Ruban Size

Find my size treats the inseam as a length. It picks the size by waist and hips, and the inseam counts for little and never pulls the answer far: short pants are short, not unwearable. When every size has the same inseam, it says so: on the Men's pants template, a shopper reads "Inseam 30 in: the same for every size". The Scrubs template puts its regular and tall inseams in a second tab, "Pants length".
