How to measure
Press-on numbers run 0–11, matching UNA GELLA gel tips. Zero is the widest tip in the box; eleven is the narrowest. Each set uses five of those numbers, thumb to pinky.
Step 1
This is the method other press-on studios use. Lay the finger flat on a table. Set a US quarter heads-up right beside it. Shoot straight down so the coin looks like a circle. Photo 1 thumb, photo 2 index/middle/ring, photo 3 pinky. Stretch the bar across the nail bed from above.
Step 2
Width is taken at the widest part of the pink nail bed — not the white free edge, and not the skin around it.
Step 3
A credit card’s short edge is about 54 mm. In Size, choose Screen and line the on-screen bar up with that edge, then match each nail.
Step 4
If you land between sizes, go down a number (wider) for a snug salon set, or up a number if you prefer a little breathing room.
Step 5
The thumb is the finger most likely to need a custom mix. If four fingers match a set and the thumb doesn’t, we can swap just that tip.
