This is the full men’s size chart for shirts and knits, pants and shorts, jackets and outerwear on Christopher Modern. It does not cover women’s letter sizes or kids’ sizes. The sizes listed on each product page are the sizes we actually sell. Questions: [email protected].

Shirts, tees, polos, and knits

XXL 50–52 in 18–18.5 in 36–37 in

Between chests: stretch tees usually take the smaller size; oxfords and rigid weaves may need the larger. Hoodies follow the same chest chart.

Letter-size pants on this shop map roughly S=30–32, M=32–34, L=34–36, XL=36–38, XXL=38–40. Stretch cargo and golf pants often take the smaller waist; rigid chinos the larger. Inseam is crotch to hem — we ship a standard 30–32 unless the product page lists another length.

S 40–42 in S shirt
M 42–44 in M shirt
L 46–48 in L shirt

Waterproof shells are cut a little roomier through the chest and sleeve. If you wear a mid-layer, size up one from your tee size.
