What size t-shirt should I order?

Unisex sizing, what “between sizes” actually means, and how to work it out from a shirt you already own and like.

2026-11-11 · Obscene A-Tee sizinghow to

Nobody knows their t-shirt size. People know their size in one specific brand they bought in 2019. That is not the same thing, and it is why so much of this gets returned. Here is how to get it right first time.

Measure a shirt, not yourself

The single most reliable method: take a t-shirt you already own and like the fit of, lay it flat, and measure straight across from armpit to armpit. That number, doubled, is the chest measurement. Match that against the size guide on the product page and you will be right.

Measuring your own chest works too, but the shirt method accounts for how you like things to fit, which is the part a tape measure cannot tell you.

Ours are a classic unisex fit

Which means straight-cut, not fitted, and not oversized either. If you normally wear something tailored, they will feel a touch roomier. If you live in oversized tees, go up a size rather than expecting a boxy fit from your usual.

Between two sizes? Go up.

Almost always. A slightly loose tee reads as deliberate; a slightly tight one reads as a mistake, and cotton does not grow. The exception is crop tops, where the shorter body means a size up can end up longer than you wanted rather than wider.

Printing does not change the size

It is worth saying because people ask: the print sits on the fabric, it does not shrink it or stiffen the shape. A printed L fits exactly like an unprinted L.

Buying for somebody else

Ask. Genuinely - "what size t-shirt are you" is a much less awkward conversation than the one where they pretend to like a shirt that does not fit. If you cannot ask without ruining a surprise, look at what they wear: a size up on a guess is more wearable than a size down.

If it arrives wrong

If something turns up faulty or it is not what you ordered, tell us straight away and we will put it right. Because almost everything is printed to order, change-of-mind returns on personalised items are not something we can offer - which is exactly why this page exists. The full returns policy is here.
