# Boxy isn't a bigger fitted tee

> It's a different pattern, not a larger one. The shoulder seam sits past the shoulder, the body doesn't taper, and sizing up in a standard tee gets you none of that.

Those two shirts are both black cotton t-shirts and they're built from different patterns. Not
different sizes of the same pattern — different shapes.

Knowing which one you're looking at explains most of the confusion people have about ordering
these.

## What actually makes a tee boxy?

Two things, and neither is "bigger".

**The shoulder seam is dropped.** On a fitted tee the seam sits on the point of your shoulder and
the sleeve is set into it. On a boxy cut the seam sits several centimetres out along your upper
arm, so the sleeve hangs from a lower, wider line.

**The body doesn't taper.** A fitted tee narrows at the waist. A boxy one runs straight down from
the chest to the hem, which is what gives it the square silhouette when it's laid flat and the
relaxed drape when it's on.

The numbers here make the difference concrete: at the same chest measurement, the boxy tee's
shoulder is **noticeably wider** than a straight cut's. Same body underneath, different
architecture over it.

## Why doesn't sizing up a normal tee do the same thing?

Because you get more of everything, including the parts that shouldn't grow.

Going up two sizes in a fitted tee gives you a longer body, a longer sleeve, a wider neck and a
shoulder seam that's now hanging in roughly the right place by accident — but the sleeve is
proportioned for a bigger person, so it's long and narrow instead of short and wide, and the
length past the hip makes it look borrowed rather than cut that way.

The boxy cut keeps a normal length and a short, wide sleeve while widening the body. That's the
combination people are actually after, and it can't be reached by sizing up.

## Does boxy mean it's huge on me?

No — and this is the most common ordering mistake in the category.

Because the pattern is already wide, you take your **normal size**. The relaxed look is built into
the cut. Sizing up from there gives you the length problem again, plus a shoulder seam somewhere
near your elbow.

If you want it dramatically oversized, one size up is the maximum that still hangs properly. Two
is a different garment.

## How do I know it'll fit before it arrives?

Measure a shirt you already like and compare, rather than measuring yourself.

A flat pit-to-pit measurement on a tee you own is the single number that predicts how a boxy tee
will feel, and it takes twenty seconds with a tape. Then check whether the chart you're comparing
it to gives the **full circumference** or the **flat width** — they differ by a factor of two, and
mixing them up is the most common sizing mistake there is.

[The full method is worth its own five minutes](/stories/how-to-pick-your-size), and it's
much more reliable than a size letter, which means different things at every brand.

## Does the cut change how a print looks?

Yes, and it's a real advantage of this shape.

A boxy tee has a wide, flat chest panel with no taper pulling at it, which means a chest print
sits square instead of curving away at the sides. Large type especially benefits — a word set
edge to edge stays straight rather than bending around the body.

That's why
[type big enough to run off the shirt](/stories/brutalist-type-poster-tee) works
better on this cut than on a fitted one.

## Who does it suit?

It's a shape rather than a size, so the honest answer is that it depends on what you want it to do.

The drape is the point: it skims rather than follows, which is why it reads as relaxed on
basically everyone and why it's become the default cut for graphic tees. If you want a garment
that shows your shape, this isn't it, and a fitted tee is a perfectly good object.

The heavier the cotton, the more the boxy cut behaves — weight is what stops a wide shirt looking
like a bag.
[That's the other half of the equation](/stories/heavyweight-cotton-explained).

## How do I get one made?

Describe the design at [JustOG](/), pick the garment and size, drag the crop frame, and see it
composited on the real thing before you order. It's made to order and shipped.

Designs other people have published are in the [shop](/shop).

It isn't a bigger shirt. It's a different one, cut to hang instead of to fit.
