The width of your nail bed at its widest point, in millimetres.
| Size | Thumb | Index | Middle | Ring | Pinky |
|---|---|---|---|---|---|
| XS | 14 | 10 | 11 | 10 | 8 |
| S | 15 | 11 | 12 | 11 | 9 |
| M | 16 | 12 | 13 | 12 | 10 |
| L | 17 | 13 | 14 | 13 | 11 |
Either method works. Measure every finger — the two hands are rarely identical.
Size is the width across your nail bed. Length is how far the tip extends past it — a separate choice.

Tip length in millimetres, measured from the base of the nail. Not every design is made in every shape or length — the options on the product page are what that set actually comes in.
Measure the widest point of each nail bed in millimetres, then enter all ten. We size every finger separately, so the answer is closer than a single guess.
We cut every set to the numbers you send us, not to the size on the box. Save them to your order note and add the closest size to your cart.
