Find Your Perfect Fit
Size charts for Sunniver adult T-shirts, hoodies, apparel, and shoes, with US and UK sizing in inches and centimeters.
How to Use This Guide
Every Sunniver item is made to order in the size you select, so choosing the right size before checkout matters. The charts below show our standard adult sizing. Each product page also includes its own size chart; if a product page chart differs from this guide, the product page chart applies to that item.
Compare a Favorite Item
Lay a shirt or hoodie that fits you well flat and compare it with the garment measurements.
Choose Your Size
If you are between two sizes, choose the larger size for a relaxed fit or the smaller size for a closer fit.
All apparel is adult unisex sizing. Women who prefer a closer fit usually order one size down from their usual unisex size. Measurements may vary by ±1 inch (±2.5 cm) because each item is printed to order and finished by hand.
Measuring Yourself
1
Chest
Measure around the fullest part of your chest, under your arms, keeping the tape level and snug but not tight.
2
Garment chest width
Lay a well-fitting shirt flat and measure straight across from armpit seam to armpit seam.
3
Garment length
Measure from the highest point of the shoulder, next to the collar, straight down to the bottom hem.
4
Sleeve length (hoodies)
Measure from the center back of the neck, across the shoulder, and down to the end of the cuff.
5
Foot length (shoes)
Stand on a sheet of paper, mark the back of your heel and the tip of your longest toe, and measure the distance. Measure both feet in the evening and use the longer one.

Our shoes run true to size. If your foot length falls between two sizes, or if you have wide feet, we recommend choosing the next half size up. Shoe sizes are selected using US Men's sizing at checkout unless the product page states otherwise.
Sizing for US and UK Customers
United States
US customers can use the inch measurements and US shoe sizes. Apparel sizes S–3XL are standard US adult sizes.
United Kingdom
UK customers can use the centimeter measurements and the UK shoe column. Apparel is labeled in the same S–3XL letter sizes, which match standard UK adult unisex sizing.
