What is standard sweater size?

Standard sweater sizes typically range from small (S) to extra-large (XL) and are often based on chest measurements. For men, sizes generally correspond to chest measurements of 34-36 inches for small, 38-40 inches for medium, 42-44 inches for large, and 46-48 inches for extra-large. For women, sizes usually range from 0-2 for small, 4-6 for medium, and 8-10 for large. However, sizing can vary by brand, so it's always best to check specific size charts.
