Press-On Nail Sizing Guide
Finding the right fit is the key to comfortable, natural-looking press-on nails. Use our guide below to measure your nails and choose the best size and shape for you.
How to Measure Your Nails
For the most accurate fit, measure the widest part of each natural nail from sidewall to sidewall, following the curve of the nail.
Method 1 — Measuring Tape
Place a flexible measuring tape across the widest part of your nail, following the natural curve. Record the measurement in millimetres (mm).
Method 2 — Paper or Tape Method
If you don't have a flexible measuring tape:
- Place a small piece of paper or tape across the widest part of your nail.
- Mark where each side of your nail ends.
- Lay the paper flat against a ruler.
- Measure the distance between the two marks in millimetres.
Important: Measure along the curve of your nail, rather than measuring straight across the top.
Standard Nail Sizes
Choose the size that most closely matches your natural nail measurements.
Not sure which size to choose?
If your measurements fall between two sizes, we recommend choosing the slightly larger size. A press-on nail that is slightly wider can usually be gently filed along the sides for a more customised fit.
For the best possible fit, measure all five nails individually before ordering.

Please Note About Nail Length
The length measurements shown in our shape chart are based on the thumb nail.
The remaining nails in your set are proportionally adjusted to create a balanced and natural-looking set.
Because every nail size is different, the length of every finger will not be exactly the same.
Choosing Your Perfect Set
For the best result:
- Measure your nails in millimetres (mm).
- Measure the widest curved part of each nail.
- Compare your measurements with our size chart.
- Choose your preferred nail shape and length.
- If you're between sizes, choose the slightly larger option.
Every Nailamonni set is designed to give you a beautiful, comfortable fit while maintaining the proportions of your chosen nail shape.
