Step 1: Measure Your Nails
Use whichever method suits you. Measure 1 is recommended because it follows the natural curve of the nail bed.
Measure 1 — Recommended
Hold a measuring tape horizontally to measure the widest curvature of your nail bed. Record the sizes.
Measure 2 — Paper Method
Hold a piece of paper against your nail bed. Use a pen to mark the widest part of your nail, then use a ruler to measure the distance between the two marks.
Step 2: Choose Your Size
Compare your nail measurements to our size chart below.
Select the size that fits most of your fingers (measurements in mm).
Consider sizing up if you are between two sizes or have flatter nail beds.
