Shirt Size Chart

Match chest or bust in cm to letter sizes for t-shirts and casual shirts. Use youth sizes for kids tops, then confirm on the brand chart when you shop.

How to measure for shirts

  • Chest/Bust: Wrap the tape around the fullest part. Keep it level; breathe normally.
  • Waist (optional): Useful for fitted shirts—measure at the natural waistline.
  • Prefer a converter? Try the top size converter or clothing size converter.

Frequently asked questions

How do I find my shirt size?

Measure your chest (or bust) with a soft tape around the fullest part, then match the number in cm to the shirt size chart. When between sizes, choose the larger letter for a relaxed tee fit.

Is a t-shirt size the same as a dress shirt size?

Letter sizes (S, M, L) are common on t-shirts and casual tops. Dress shirts may also use neck and sleeve numbers. Use chest/bust from this chart as a starting point, then check the brand chart for the exact style.

What is a youth shirt size chart?

Youth shirts usually use letter sizes XS–XL keyed to height and chest, not adult letter sizes. Use the youth section below or our kids size chart hub for age and height guidance.
