Find your size

Press-on size is the width of each nail plate in millimetres — measured for all 10 fingers and mapped to sizes 0–9. Shape and length do not matter here.

  1. Wrap a strip of paper or a flexible tape across the widest part of the nail.
  2. Mark where the strip meets the nail edges.
  3. Measure the distance in millimetres — with a ruler or the on-screen ruler below.

On-screen ruler

No ruler at hand? Calibrate your screen with a payment card and measure the strip right on your phone.

1. Hold any payment card against the screen and drag the slider until the frame matches the card width exactly.

2. Hold your marked strip against the ruler and read the millimetres.
