Fit tips
- Pick the size that fits most of your fingers. Almost nobody matches one size on all ten.
- Between two sizes or flatter nail beds? Size up. A slightly wide tip sits flush, a narrow one lifts.
- Short almond tips run a little small, so size up for those.

Measure every finger. Your two hands are rarely the same.
- Lay the tape flat across the widest part of your nail bed, following its curve.
- Note the mm mark. Repeat for all ten nails.
- Lay a strip of paper or tape across the widest part of your nail.
- Mark a dot at each edge of the nail bed.
- Peel it off and lay it flat on a ruler.
- The gap between the dots is your width.
Measure your natural nails, not over acrylic or gel.
