Size Guide
Every AEGIDŌ item is made to order in the size you choose, so please measure before ordering rather than guessing. Measurements are in centimetres. Most are body measurements — measure yourself and match the closest size. Two are different, and say so in their own section: the youth tee chart measures the garment laid flat, and socks are matched to shoe size.
We cannot exchange an item for a different size if the one you received matches the measurements below. Please see our Refund and Returns Policy.
How to measure
- Chest — around the fullest part, under the arms, tape level and not pulled tight.
- Waist — around your natural waistline.
- Hips — around the fullest part.
- Length — from the highest point of the shoulder straight down.
Measure over light clothing. If you fall between two sizes, take the larger one. Compression garments such as rash guards are meant to fit close; tees are not.

Youth tees
Sizes XS to XL. For this garment the measurements are of the tee itself laid flat, not of the body. The easiest way to use them: take a tee that already fits your child well, lay it flat, and measure it the same way.
- Length — from the highest point of the shoulder straight down to the hem.
- Width — straight across the chest, armpit to armpit, with the tee lying flat.
| Size | Length (cm) | Width, flat (cm) |
|---|---|---|
| XS | 45.7 | 35.6 |
| S | 52 | 40.6 |
| M | 56 | 43.2 |
| L | 59.7 | 45.7 |
| XL | 63.5 | 48.3 |
Socks
Sizes M to XL, matched to shoe size. Find your size in whichever system you already know.
| Size | UK shoe | EU shoe | US men’s shoe | US women’s shoe |

| L | 8 – 10.5 | 42 – 45 | 9 – 11.5 | 10 – 12.5 |
| XL | 11 – 13.5 | 46 – 49 | 12 – 14.5 | 13 – 16 |
Sizes differ between garments
Our range uses different garment styles and their size runs are not identical. The swim trunks run 2XS to 6XL, the swimsuit stops at 3XL, adult tees run S to 5XL, youth tees run XS to XL, and socks are sized by shoe size. A size that fits you in one item will not always be the right size in another, so please check the chart for the specific item you are buying.
