Find your nail size

It only takes a couple of minutes.

How to measure

  1. Step 1: Grab a tape

    Use a soft measuring tape, or a strip of paper or tape and a ruler.

  2. Step 2: Measure each nail

    Measure the widest part of each nail from side to side, in millimetres.

  3. Step 3: Note them down

    Write down all 10 measurements — left and right hand. No decimals, round up.

  4. Step 4: Match your size

    Find the size where most of your nails match. If you're between sizes, or your fingers fall in different sizes, size up.
