Two minutes, one measurement
Size guide
Kigurumi sizing runs on height, not on chest or waist. Measure once, pick the band your height falls into, and you are done. Getting this right is the single biggest thing you can do to avoid sending something back.
How to measure
Stand barefoot with your back against a wall, heels touching it, standing up straight. Get someone to mark the wall level with the top of your head, then measure from the floor to the mark. That number is all you need.
If you land between two bands, size up. Onesies are cut loose on purpose, the extra length sits in the body and the sleeves, and the cuffs are ribbed so nothing trails. A onesie that is slightly big is comfortable. One that is slightly small pulls at the shoulders and stops getting worn.
The tables
Adults get letter sizes. Children and babies are numbered by height in centimetres, so a 120 fits a child of roughly 115cm to 125cm. Age labels are not used, because two children of the same age can be fifteen centimetres apart.

Measurements are approximate and can vary slightly between designs. Where a design has its own manufacturer table, that table is shown on the product page and it wins over the ones above.
What has no size at all
Lazy robes and hoodie blankets are made one size and are meant to be oversized. Your height changes where the hem falls, not whether it fits. If you are buying for someone else and you cannot ask how tall they are, those two are the safe choice.
If you still get it wrong
Size swaps are the most common reason anything comes back to us, and they are not a problem. You have thirty days to return an item on top of your statutory fourteen day right to cancel, both explained in full on the returns page.
