Size Guide
Use these measurements as a general guide. Exact sizing can vary by garment and brand.
How to find your size
The easiest way is to measure a shirt you already own and like.
- Chest: Lay the shirt flat and measure straight across from underarm to underarm. Double that number for the full chest measurement.
- Length: Measure from the highest point of the shoulder beside the collar down to the hem.
You can also measure around the fullest part of your chest and compare it with the table below.
Unisex sizes
“To fit chest” is your body measurement. “Garment chest” is the width of the shirt when it is laid flat.
| Size | To fit chest | Garment chest, flat | Body length |
|---|---|---|---|
| XS | 32–34" | 17" | 27" |
| S | 34–37" | 18" | 28" |
| M | 38–41" | 20" | 29" |
| L | 42–45" | 22" | 30" |
| XL | 46–49" | 24" | 31" |
| 2XL | 50–53" | 26" | 32" |
| 3XL | 54–57" | 28" | 33" |
| 4XL | 58–61" | 30" | 34" |
| 5XL | 62–65" | 32" | 35" |
Youth sizes
Youth sizing is available on many garments.
Because measurements can vary by brand and style, we will send the exact size chart for the garment you choose.
Fit can vary
Different garment brands fit differently. Some fitted or retail-style garments are slimmer than standard unisex styles.
If you are between sizes or choosing a fitted style, sizing up may be more comfortable.
Once you choose a garment, we can confirm its exact measurements before production.
