Women's Tee Size Guide

Fortem women's tees use a relaxed women's fit. Use the US Size range as your starting point, then compare Shirt Width and Shirt Length to a tee you already own. If you're between sizes or prefer additional room, size up.

Size US Size Shirt Width Shirt Length
S 2–6 18 ½ in 25 ¼ in
M 6–10 20 in 26 in
L 10–14 22 in 26 ¾ in
XL 14–18 24 in 27 ½ in
2XL 18–22 26 in 28 ¼ in
3XL 23–27 28 in 29 in

How to measure

  • Shirt Width: Lay a similar tee flat and measure straight across the chest.
  • Shirt Length: Measure from the highest point of the shoulder down to the hem.

Measurements may vary slightly.

Women's relaxed fit. True to size for an easy fit. Size up for additional room.
