How to Measure Your Nails for Press-On Nails

How to Choose Your Press-On Nail Size
1. Measure Your Nails
Use a press-on nail size guide to record each finger’s width in millimetres.
2. Count Your Sizes
Note which nail size appears most often across your fingers.
3. Choose the Majority Size
Choose the most frequent size for a better overall fit. If you find yourself tied between two sizes, go with the larger one and file it down.
This simple method ensures that your handmade press-on nails will match your natural nail shape comfortably.

Main Size Chart
To select the correct size for your press-on nails, follow these simple steps:
- Measure your nails using a nail sizing chart to find the best fit for each finger.
- Count the number of nails that match each size. For example, if you have 4 size S and 6 size XS, choose the XS size since it’s the majority.
- If you have an equal number of two sizes, such as 5 XS and 5 S, choose the larger size (in this case, size S).
- If there’s an unequal number, pick the majority size.
This ensures a better fit and more comfortable wear!
