Size Guide
Our sets come in XS, S, M, and L — sized by nail bed width, not nail length. If you've worn press-ons before you may already have a feel for it; if not, a quick measure takes under a minute and the chart below will tell you exactly where you land.
How to measure
Measure each nail bed at its widest point — width, not length.
- 1
Cut a thin strip of clear sticky tape or use a soft measuring tape.
- 2
Press it flat across the widest part of each nail bed, from one side to the other. Mark both edges with a pen.
- 3
Peel the tape off and lay it flat on a table. Measure the distance between the marks in millimetres. Write down all five fingers.
Nail bed widths (mm)
Match each of your five fingers to the range that fits — the size where most fingers land is yours.
| Size | Thumb | Index | Middle | Ring | Pinky |
|---|---|---|---|---|---|
| XS | 13–14 | 9–10 | 10–11 | 9–10 | 6–7 |
| S | 14–15 | 10–11 | 11–12 | 10–11 | 7–8 |
| M | 15–16 | 11–12 | 12–13 | 11–12 | 8–9 |
| L | 16–17 | 12–13 | 13–14 | 12–13 | 9–10 |
All measurements in millimetres.
Which size am I?
Extra Small
Exceptionally narrow nail beds — less common, but real. If standard press-ons have always been a little wide for you, this is yours.
Small
Narrow nail beds or smaller hands. Usually the right fit if you've found standard sizing consistently too wide.
Medium
Fits most hands. If you're unsure and don't have a strong sense that your nails run narrow or wide, start here.
Large
Wider nail beds or broader hands. The right call if standard sizing has always felt slightly too snug across the nail.
Not sure which you are?
Medium fits the majority of hands. If you know your nail beds run noticeably narrow compared to most people you know, try Small — or Extra Small if they're very narrow. If they run wide, go Large.
Between two sizes?
Go smaller. A set that's very slightly narrow is barely noticeable and still adheres cleanly — one that's too large is far more likely to lift at the edges. When in doubt, size down.
