Custom sizing — the coin method

1. Prep: Clear your nails of all polish or extensions. 2. Position: Place your hand flat on a table with the coin flat right next to your fingers. 3. Thumb: Take a separate photo of your thumb flat on the table with the coin next to it. 4. Snap: Hold your phone directly overhead and photograph straight down. Do not tilt the camera. 5. Repeat: Take these photos for both hands (4 photos total). Make sure your photos are bright, in focus, and shot from a perfect bird's-eye view.

  1. Photo 1: your four fingers flat, side by side, with the coin next to them.
  2. Photo 2: your thumb flat, with the same coin next to it.
  3. Take both from directly above, in good light.
