How to choose your press-on nail size: the complete guide
Size is THE factor that makes the difference between press-on nails that last 14 days and nails that pop off on the first night. Here's how to find your perfect size—in-store or at home.

The golden rule: the nail must cover edge to edge
A well-sized press-on nail covers your natural nail from one edge to the other, without overlapping onto the skin, and without leaving any empty space. If you're hesitant between two sizes: choose the larger one and file the sides.
Method 1: In-store fitting (Geneva or Lausanne)
This is the most reliable method. Come without an appointment to Rue de la Cité 18 (Geneva) or Rue du Grand-Pont 4 (Lausanne):
- We'll help you find your size for each finger.
- You'll try on 3–4 pairs to compare the look.
- You'll leave confident you have the right size.
Method 2: Measure at home
- Take a flexible tape measure or a ruler.
- Measure the width of your nail at its widest point (in mm).
- Refer to the size guide below.

Special case: wide or flat nails
If you have naturally wide nails or a flat nail plate (not very curved): choose one size up and file the sides. MIBLAB press-on nails are thin enough to adapt to your nail's curvature without creating tension.
