Fit first
Find your size
Every set ships in a size range — ten nails sized for your hand, ready to fine-tune with the included file. Three minutes of measuring gives you weeks of perfect fit.
Step 01
Grab something to measure with
A soft measuring tape is ideal. No tape? Lay a thin strip of paper across your nail, mark both edges, and measure the strip against a ruler.
Step 02
Measure the widest part of each nail
Measure straight across the widest point of the nail bed, side to side, in millimetres. Don’t curve the tape over the nail — keep the measurement flat.
Step 03
Match your widths to the chart
Compare your thumb, index, middle, ring and pinky widths to the ranges below. Most people match one range across all five fingers.
Size ranges — nail width in mm
| Range | Thumb | Index | Middle | Ring | Pinky |
|---|---|---|---|---|---|
| XS | 15.5 | 11.5 | 12.5 | 11.0 | 8.5 |
| S | 16.5 | 12.0 | 13.0 | 11.5 | 9.0 |
| M | 17.5 | 13.0 | 14.0 | 12.5 | 10.0 |
| L | 18.5 | 14.0 | 15.0 | 13.5 | 11.0 |
Between two sizes?
Always size up. A slightly wide nail files down to a perfect fit in seconds — a nail that's too narrow can't be stretched.
Keep your numbers
Write your five widths down once and reordering takes seconds. Soon your account will remember them for you.
