There are two different ways to find your perfect size.

For the most accurate fit, use a measuring tape.

Measure the curve of the widest part of each nail. Then, find your nail size on the chart below.

If your measurements fall predominantly into size M,

order size M (e.g., if 3 of your fingers are size M and 2 are size S).

Mobile Size Chart Comparison

You can also determine your size using the comparison images, which are located in the product gallery of every set

(select any nail pair and scroll through the pictures until you reach the Mobile Size Chart images).

Download the image to your phone and place a credit card over the screen. Scale the image until the on-screen card matches

the physical card's size, and then compare your nails to the sizes shown.

For the most accurate fit, use a measuring tape (instructions are provided below).

Wrap measurement tape around the nail and measure the curvature of the widest part of the nail. If most of your nails fall under size M, you are a size M.
