How to Choose a T-Shirt Size Online

Choosing a T-shirt size online is easier when you start with a garment you already like wearing. Brand sizing can vary, so the label in your wardrobe is a useful starting point—but the measurements and fit notes on the product page are the details to trust.

Start with a T-shirt you already like

Lay a clean, dry T-shirt flat on a table. Smooth it gently rather than stretching it. Measure across the chest from underarm to underarm, then compare that measurement with the size information provided for the product you are considering. This gives you a useful reference for both width and the kind of fit you enjoy.

Decide how you want it to fit

Think about the shape you are looking for before choosing a size. For an easy everyday fit, compare with a T-shirt you already wear often. For a roomier feel, check the product page and choose according to the stated measurements rather than assuming every style fits the same way. A women’s cut, a unisex cut and a hoodie can each sit differently.

Use the product page as the final check

Before adding an item to your basket, check the listed size options, fit notes and product details. The individual product page is the most useful source because it relates to that exact garment. If you are between sizes or would like a second opinion before ordering, get in touch.
