What You Need
Use tape or a paper strip.
Use a flexible measuring tape. If you do not have one, place clear tape or a narrow paper strip across the nail, mark both sidewalls, then measure the marked width with a ruler.
Nail Guide
Measure every natural nail in millimetres, compare your numbers with S, M and L, then confirm all ten fits before adhesive.
Choose the Right Fit
SELViARE press-on nails are currently available in S, M and L. Use the chart as a natural-nail width reference, then dry-fit every press-on. The correct piece covers the nail from sidewall to sidewall without touching skin or creating pressure.
How to Measure
What You Need
Use a flexible measuring tape. If you do not have one, place clear tape or a narrow paper strip across the nail, mark both sidewalls, then measure the marked width with a ruler.
Measure Each Nail
Measure the widest part of the natural nail from sidewall to sidewall. Follow the visible width of the nail plate and do not include surrounding skin.
Both Hands
Repeat the process for every nail on the left and right hand. Corresponding fingers can differ, so do not assume both hands have identical measurements.
Fit Check
Place every press-on over the natural nail before using adhesive. Confirm sidewall coverage, comfort, and alignment for all ten nails.
SELViARE Size Chart
Compare your natural-nail widths with the closest row. Measurements are listed from Thumb to Pinky and refer to width, not press-on length.
| Size | Thumb | Index | Middle | Ring | Pinky |
|---|---|---|---|---|---|
| S | 15 mm | 11 mm | 12 mm | 11 mm | 9 mm |
| M | 16 mm | 12 mm | 13 mm | 12 mm | 10 mm |
| L | 17 mm | 13 mm | 14 mm | 13 mm | 11 mm |
Reference only: These are common S / M / L natural-nail width references compiled from public press-on sizing charts; press-on sizing is not universal across brands. Nail shape and C-curve also affect fit. Dry-fit all ten pieces before applying glue or adhesive tabs.
Fit Guidance
Between Sizes
If your measurements sit between two rows, compare the whole five-finger pattern. Choose the set that covers the nail plates without touching skin or creating pressure; only a slightly wider plain edge should be filed gently.
Comfort Check
The press-on should cover the nail plate without overlapping or pressing into the surrounding skin or cuticle.
Before Adhesive
Lay out the chosen sizes in order and perform a final alignment check before opening glue or adhesive tabs.
