Your 60-second fit check
One measurement. One clear starting size.
Use soft tape or a ruler across the widest part of your natural thumbnail, from edge to edge, without including skin.
The fit test
Never force a smaller nail.
When you sit between two widths, begin with the larger size and refine the sidewall gently with the included mini file.

Your best starting size
S
For a 13 mm widest nail, start with S. This corresponds to our narrow fit family.
This is a starting recommendation. Confirm all ten nails because natural widths can differ between hands.
How to measure
Three steps. No guesswork.
Measure before application, on clean natural nails with nothing touching the sidewalls.
