T-Shirt Size Guide

Measure a T-shirt you love, laid flat. All sizes below are garment measurements.

Size Chest width
M 20″ / 50.8 cm
L 22″ / 55.9 cm
XL 24″ / 61 cm
XXL 25″ / 63.5 cm

Approximate garment width, measured flat. Full chest circumference = width × 2.

Measure in seconds

1. Lay your favorite tee flat. 2. Measure across the chest, 1″ (2.5 cm) below the armholes. 3. Match it to the chart.

How do you like it?

FITTED

Closer to the body. Choose your usual fitted-tee width.

RELAXED

More room, easy feel. Go roomier if you're between sizes.

Height & weight fit guide

Quick size estimate, not a guaranteed fit. Height in cm / weight in kg.

Height Weight Fitted Relaxed
160–170 50–60 M L
165–175 60–70 M L
170–180 70–80 L XL
175–185 80–90 L–XL XL–XXL
180–190 90–100 XL XXL

Example: 180 cm / 80 kg → L fitted, XL relaxed.

Guide only. Body shape and fit preference vary. For the best fit, measure your own T-shirt and match the Size Chart above. Chest measurements are more reliable than height and weight alone.
