Size Guide

Real measurements from real ShirtBoom customers — use this to gauge how our sizes wear on different body types.

1. Chest

Measure the full circumference around the chest at the fullest part, just under the arms — keep the tape level all the way around.

2. Shoulder Width

Measure straight across the back, from one shoulder seam to the other shoulder seam.

3. Bottom Opening

Measure the full circumference around the bottom hem opening of the shirt — all the way around, not just edge to edge.

4. Shirt Length

Measure from the highest point of the shoulder seam straight down to the bottom hem.

5. Sleeve Length

Measure from the shoulder seam down the outside of the sleeve to the cuff edge.
