# Size guide

Your size in thirty seconds: height, weight and, if you have a tape measure, chest. We also give you our error degree.

## The calculator

## The chart

| Size | Recommended chest | Flat width | Length |
| --- | --- | --- | --- |
| XS | 82–87 | 47 | 68 |
| S | 88–95 | 50 | 70 |
| M | 96–103 | 53 | 72 |
| L | 104–111 | 56 | 74 |
| XL | 112–119 | 59 | 76 |
| XXL | 120–127 | 62 | 78 |
| 3XL | 128–135 | 65 | 80 |

Width and length: garment laid flat, from the printer's sheet for this model. Between two sizes, go bigger. Too big gets worn, too small gets regretted.

## Four body types, zero judgement

***Slim** Good choice. Take your real size: an "just in case" XL is a dress.*

***In between** No risk. You are the average the size guides are built on.*

***A bit of a belly** Great choice. Just avoid the crop top: you have been warned.*

***Built** It holds. The shoulder seams told us it would.*

## How to measure

Measure your chest under the arms at the widest point, tape level, without squeezing or taking a deep breath. No tape measure? Lay a t-shirt that fits you well flat and measure it from armpit to armpit: compare with the “flat width” column.

## Between two sizes?

Go bigger. A slightly big t-shirt gets worn, a small one gets regretted. For a fitted look, keep your usual size.

## Products with no size

Caps, bucket hats, bags, mugs, posters and stickers have no size. They are the answer when you are buying for someone whose measurements you do not know.
