How to measure
The fastest honest method: take a t-shirt you already like the fit of, lay it flat, and measure it. Compare those numbers to the tables below rather than measuring your body — it removes the guesswork about how much room you like.
- Chest — measure straight across the garment from armpit to armpit, then double it for the full circumference.
- Length — from the highest point of the shoulder straight down to the hem.

Measured flat, tolerance about ±2cm — normal for heavyweight cotton. Everything is pre-shrunk, so a 30°C wash will not cost you a size.
