How to Measure Each Nail

Do this on both hands, all 10 nails β€” your nail beds are rarely identical side to side, and custom sizing only works if we have every measurement.

  1. Push back your cuticle gently so you can see the true base of the nail bed.
  2. Line up the 0cm mark of your tape with one edge of your nail bed (side wall to side wall, at the cuticle line β€” the widest part of the nail).

  3. Wrap the tape straight across to the opposite edge and read the number where the tape lands β€” that number, exactly as shown (including the decimal), is your measurement in centimeters. No subtracting, no counting individual markings. Example: if the tape reads 1.6cm at the far edge, your nail bed width is 1.6cm.
  4. Repeat for every nail β€” thumb, index, middle, ring, pinky β€” on both hands.

Tip: Measure at eye level and keep the tape flat against the nail bed, not angled or pulled tight β€” pulling too tight will give you a size that runs small.

Compare your measurements to the table in the product page, nail by nail. If each of your measurements isΒ within 0.1cm of the number listed, this set will fit you comfortably β€” go ahead and order as-is.

If one or more nails are off by more than 0.1cm, we can make you a set in your exact measurements β€” request a made-to-order set here.
