Nail Sizing Guide

Getting the correct size is very important for the best fit.
All measurements are taken from the widest part of the nail in millimetres (mm).

You can choose from:

  • Pre-set sizes (XS–XL)
  • Custom measurements
  • Coin method sizing

Please follow the instructions carefully to avoid sizing issues.

Pre-set Sizes (XS–XL)

We offer pre-set sizes for convenience. These sizes are based on the width of each nail in millimetres.

Sizes are based on the widest part of each nail.
If you are between sizes, choose custom sizing or the coin method.

How to Measure Your Nails (Custom Sizes)

To get the most accurate fit, measure the widest part of each nail using a tape measure or ruler.

Instructions:

  • Measure the widest part of each nail
  • Write sizes in mm
  • Order format must be: Thumb – Index – Middle – Ring – Pinky

Coin Method Sizing (Recommended for Best Fit)

If you are unsure of your size, you can upload photos of your nails next to a coin or card. This allows us to measure your nails accurately.
