About the T-Shirt Size Calculator
Buying a shirt online always comes with one nagging question: will it actually fit? This free calculator takes the guesswork out. Enter your height, weight, body build, and how you like your shirts to fit, and it recommends your best unisex tee size, then highlights it on the real size chart for our Gildan 5000 shirts. Sizing by height and weight alone isn't perfect — bodies vary — which is why we factor in build and fit preference too, and show you the chest and length measurements so you can double-check against a shirt you already own. The result: fewer returns, and a tee that fits the way you like it.
Frequently asked questions
How do I know my t-shirt size?
The most reliable way is to measure your chest at its fullest point and compare it to the size chart, then check shirt length against a tee you like. This calculator estimates your size from height, weight, build, and fit preference, and points you to the matching row on the chart so you can confirm.
Are unisex t-shirts true to size?
Unisex tees like the Gildan 5000 generally run true to size with a classic, slightly boxy fit. Women who prefer a closer cut often size down one, while anyone wanting a relaxed, oversized look should size up. Our calculator adjusts for your fit preference automatically.
Should I size up or down if I'm between sizes?
If you're right between two sizes, size up for comfort and a relaxed drape, or size down for a fitted look. Keep in mind 100% cotton tees can shrink slightly in a hot dryer, so sizing up is the safer choice if you machine dry.
