Buying a shirt you can’t try on is a leap. This page is here to make it a short one.
The most reliable method isn’t measuring yourself — it’s measuring a shirt you already own and love. Bodies are three-dimensional and garments are flat; comparing flat-to-flat removes all the guesswork about how much room you like.
How to measure a shirt you already own
Lay it on a flat surface, smooth out the wrinkles, and don’t stretch it.
- Chest — measure straight across, seam to seam, one inch below the armhole. This is a flat measurement, so it’s roughly half the way around. Compare it to the chest column below as-is; don’t double it.
- Length — from the highest point of the shoulder straight down to the hem.
- Sleeve — from the centre back of the collar to the sleeve’s end.
Then find the row below with the closest chest number. Chest is what makes a shirt fit or not fit; length is a preference.
Between two sizes? Size up. Our tees are cut about an inch longer in the body with a regular fit — sizing up reads as relaxed, not oversized.
