How Columbia sizes really run
Every garment that passes through this shop is measured laid flat before it is listed. This page is what 138 real Columbia garments actually measured, grouped by the size on their labels — not the manufacturer's chart, the tape measure's verdict. The number to look at is the range: the same label size can vary by inches between eras and cuts, which is exactly why every listing here carries its own measurements.

How to use this: lay a garment that fits you flat, measure armpit to armpit and collar to hem, and compare against the listing's own measurements — every product page here carries them. The medians above say where a size usually lands; the ranges say how far it can wander.
