Note: Men's big-and-tall letter sizes are not fully standardised: some makers shift the whole ladder up, labelling a 46 to 48 inch chest as 2XL instead of XL, so these are the most common convention rather than a fixed rule. Chest in centimetres continues the site's own chart at about 5 cm per two inches.
