THE QUARTER METHOD

The most accurate way to size your press-ons from home — no printer, no ruler, just your phone and a quarter.

WHAT YOU'LL NEED

BEFORE YOU START

One Quarter

Any US quarter, placed heads up

Your Phone Camera

Held directly overhead

Flat, Bright Surface

Even light, no harsh shadows

Bare, Flat Fingers

No rings, resting flat on the surface

THREE PHOTOS, PER HAND

WHAT TO SHOOT

Repeat all three for your other hand — six photos total. Upload them with your custom order.

Photo 1

INDEX, MIDDLE & RING

Together, flat, with the quarter placed beside them.

Photo 2

THUMB ALONE

Its own shot — thumbs sit at a different angle than the rest.

Photo 3

PINKY ALONE

Your smallest nail deserves its own clean shot too.

GETTING IT RIGHT

DO'S AND DON'TS

DO

  • Hold the camera directly overhead, straight down
  • Lay fingers completely flat on the surface
  • Place the quarter heads-up, right next to the nail
  • Shoot in even daylight or bright, shadow-free light

DON'T

  • Shoot at an angle — it distorts the sizing
  • Let fingers curl or lift off the surface
  • Rest the quarter on top of the nail
  • Use a blurry, dark, or shadowed photo
