Measure a shirt that fits you well, laid flat. Chest is measured 1 inch below the armpits, side to side, then doubled. Length is from the highest point of the shoulder to the hem. These charts follow standard US athletic sizing. Adult sizes run men's/unisex XS-5XL and women's XS-3XL; youth sizes run YXS-YXL (jerseys and polos). Fabrics are 140-160 GSM polyester knits with little stretch, so follow the chart rather than sizing down.
