Thigh

Thigh is the distance around the upper leg at its fullest, just below the crotch. On pants, it is the width of the leg at the same height, measured laid flat. It matters on slim and skinny cuts, where a pair can close at the waist and still be tight on the leg.

How to measure

On the body:

1. Stand straight, feet slightly apart, weight on both legs.
2. Wrap the tape around the fullest part of one thigh, just below the crotch, level.
3. Snug, not tight. Read and note the unit.

On pants laid flat:

1. Smooth one leg flat, front up.
2. Measure straight across it, just below the crotch seam, edge to edge.
3. Double it for the circumference: a 30 cm width is a 60 cm thigh.

On a size chart

Thigh is mostly a garment measurement, listed with the rise and the leg opening on pants specs. None of Ruban Size's 39 templates has a thigh row: the pants templates size by waist, hips and inseam. If a slim fit runs narrow in the leg, a thigh row in a garment tab is how a shopper with muscular legs finds out before ordering. Say whether it is laid flat or around.

In Ruban Size

Find my size doesn't ask for the thigh: on pants it weighs the waist and the hips. Add the row in a garment tab, with a caption that says how it was measured ("laid flat, just below the crotch"), and the cm/in switch converts it like every row that has a unit. In the size chart editor, you can paste the values straight from Excel, Numbers or Google Sheets.
