Close, but not quite 36"

These are within 1.5" of 36". Worth a look if you like a slightly cropped or extra-long fit, or if the cut runs long.

Next — closest is 35". Next size guide: Long 31", Extra Long 33", Tall 35" (Tall range for 5'10"+, sizes 6–20). Individual styles can differ.
M&S — closest is 35". M&S chart: Extra Short 27" to Extra Long 35" (body inside leg). UK product page confirms styles in extra short to extra long; length chart read from M&S's India site, not the UK site. Example price: Embellished Straight Leg Jeans £55 (UK site).
Gap Tall — closest is 34.5". Gap Tall Atlantic straight leg: garment inner leg 34.5" (size 27). This is a garment measurement, not 'to fit'. Gap UK site blocked our check.

How to measure your inside leg

In bare feet, measure from the crotch down to the floor (some brands say to the ankle bone — Long Tall Sally and New Look use crotch-to-floor; ASOS and Gap use crotch-to-ankle). Use a pair that already fits as a sanity check: lay it flat and measure the inner seam.

"To fit" vs "garment" length. Most UK brands label trousers by the body inside leg they're made to fit (e.g. New Look's "to fit an inside leg of"). A few listings give the measured garment seam instead — we flag those in the notes. A 36" "to fit" and a 36" garment seam won't hang identically.

How we checked

Every length above comes from the brand's own size guide or product page, or a named UK retailer when the brand's site blocked us. Each row links to its source and shows the date checked. If you spot something out of date, tell us.
