Size Chart
All measurements are in millimetres (mm) and refer to the width of each nail. The thumb measurement is used as the base — all other fingers are scaled to fit proportionally.

How to Measure
Your Nails
Three simple steps to find your size before ordering — no guesswork needed.
01
Find a Ruler
Use a millimetre ruler or a flexible tape measure. Make sure your nails are clean and dry before measuring.
02
Measure the Width
Place the ruler at the widest point of each nail, from one edge to the other. Record the measurement in mm.
03
Match to Chart
Start with your thumb measurement and compare it to the size chart above. When between sizes, size up for a more comfortable fit.
04
Go Custom
If your measurements don’t match any standard size, select “Custom” and note all five finger widths in the order notes.

Common Questions
What if I'm between two sizes?
We recommend sizing up. A slightly larger nail can be gently filed to fit, while a nail that’s too small won’t cover your nail bed properly and may pop off sooner.
Are both hands measured the same?
Most people have slight differences between hands. We recommend measuring your dominant hand and noting any differences for a custom order. Standard sets are made for one hand size.
Can I choose a different shape for the same size?
Yes! Size refers to the width, and shape refers to the tip style. You can select any shape (square, almond, coffin, stiletto, etc.) independently of your size.
How long do press-on nails last?
With proper application and care, our press-ons last 1–3 weeks. Using nail glue (included) and avoiding prolonged water exposure will extend the wear time significantly.
What's included in a custom order?
A custom set includes 10 individually fitted nails (one full set), nail glue, a prep pad, and a mini file. Please allow 5–7 extra business days for custom production.
