How to measure boxers
Every point, drawn on the garment so there is no guessing where the tape goes.
Quick answer
Lay the boxers flat and measure five points in fit order: waist, rise, length, width and hem. The waistband is taken across one relaxed layer and doubles to the body waist, the number most sellers eyeball. Rise, length, width and hem are single runs you record as-is. Hover or tap each step on the diagram.
Anyone buying boxers checks the waist first, since the band is what holds them up and decides comfort all day. Rise then sets how high they sit and length sets how far down the leg they reach. Generic guides give you waist and call it done. This page draws all five points on the garment, so the leg fit is as clear as the band.
- A
Waist
Across the top of the relaxed waistband, edge to edge on one flat layer. Tap this step for the exact line. The band sets whether they stay up without digging in, so it leads the fit.Double it for the full waist circumference.
- B
Rise
A single vertical run from the top of the waistband down to the crotch seam at the front. The diagram shows the path. Rise decides how high the boxers sit and how much coverage you get above the leg.Recorded as-is. Do not double.
- C
Length
From the waistband down the outside of the leg to the bottom hem, following the side of the garment. Tap the step to see where it ends. Length is what separates a short boxer from a mid-thigh cut.Recorded as-is. Do not double.
- D
Width
Across the leg at the widest point of the thigh, taken flat. This sets how roomy the leg sits before it reaches the opening, which matters most on a fitted knit boxer.Recorded as-is across one layer. Do not double unless you want the full leg loop.
- E
Hem
Across the bottom leg opening, edge to edge. A wide hem hangs loose, a snug hem grips the thigh. Tap the step on the diagram to see the exact span.Double it for the full leg-opening circumference.
Measure flat and never stretched, which is the whole game with knit boxers because a tugged waistband can read four inches too big. Let the band relax fully on one layer before you read it. Of these five, only the waist is an across measurement that doubles to a body circumference. Rise, length, width and hem are linear runs you write down exactly as the tape reads them.

Frequently asked
Do I double the waist measurement on boxers?
Yes for the waist. It is taken flat across one relaxed layer, so the body waist is roughly double the flat number, meaning a 16 inch flat waistband is about a 32 inch waist. Rise, length, width and hem are single runs you do not double. Listing the flat waist lets a buyer compare it to boxers they already own.
What size boxers am I from a waist measurement?
Measure your own waist where the band sits, then match it to the body waist on the chart, not the flat number. Boxers run close to jeans waist sizing, so a 32 inch waist usually lands at a medium, though knit fabric and brand cut shift it. For a cross-brand US, UK and EU view, see our men's international size chart.
What is the difference between rise and length on boxers?
Rise is the vertical distance from the waistband to the crotch seam, so it sets how high the boxers sit on the body. Length is how far the leg runs down the thigh from the waist to the hem. A boxer can have a low rise with a long leg, or a high rise with a short leg, so both belong on the chart.
How do I measure boxers that have a stretchy waistband?
Lay them flat and let the elastic fully relax before reading, never pulling the band taut. A stretched reading overstates the size by inches. For resale, record the relaxed flat waist and mention the fabric has stretch, since a buyer needs the resting size, not the maximum the band can reach.
Should I measure boxers in inches or centimeters?
Either works as long as you label the unit and stay consistent across the listing. Sellers shipping abroad do best showing both, since one buyer thinks in inches and another in centimeters. Sizely lists both on every chart so no buyer has to convert the waist or rise in their head.
