Unisex T-Shirt Size Guide: How to Choose Between XS and 5XL

How unisex t-shirt sizing works, how it differs from men's and women's sizing, how to measure yourself accurately, and how to pick between sizes for the fit you want.

Unisex sizing trips people up because it is not the same as either men's or women's sizing. This guide explains how to pick the right size the first time.

What "unisex" actually means

A unisex t-shirt is cut on a men's block: straighter through the body, wider at the shoulder, with a slightly longer sleeve than a women's cut. It is not a neutral middle point between the two.

The practical rule: if you normally wear women's sizing, a unisex tee will fit roomier than the same nominal size. Many people who wear a women's medium prefer a unisex small.

How to measure yourself properly

Measurements beat guesswork. You need two numbers:

  1. Chest: measure around the fullest part of your chest, under the arms, keeping the tape level and snug but not tight.
  2. Length: measure from the highest point of the shoulder straight down to where you want the hem to sit.

Then compare those against the size chart on the product page rather than against your usual letter size. Sizing varies between garment styles, so check the chart for the specific item.

Choosing between two sizes

  • Want a relaxed or oversized look? Size up. This is also the right call if you plan to layer.
  • Want a fitted look? Stay true to size, or size down if you are between sizes.
  • Buying a hoodie or sweatshirt? Most people size up one from their t-shirt size, since these are worn over another layer.
  • Between sizes on chest but not length? Prioritise the chest measurement - length is far more forgiving.

Will it shrink?

Ring-spun cotton tees can shrink slightly in length on the first hot wash. Washing cold and tumble drying low essentially eliminates this. If you machine dry on high regularly, factor in a small amount of shrinkage when choosing between sizes.

Frequently asked questions

Do unisex t-shirts run big or small?

They run true to men's sizing, which means they feel large to anyone used to women's sizing. Compare chest measurements rather than letter sizes.

What size should I order for an oversized fit?

One or two sizes above your measured size. Two sizes up gives a noticeably boxy, streetwear-style drop shoulder.

How do I measure chest size without help?

Use a soft tape in front of a mirror, keeping it level under your arms. If you only have a rigid ruler, measure a t-shirt that already fits you well: lay it flat, measure armpit to armpit, and double that number.

Are sizes the same across t-shirts, hoodies and sweatshirts?

No. Each garment style has its own chart. A medium hoodie and a medium tee are not interchangeable.
