The NEEVANAILS size guide: measuring from XS to XL
A tape measure, two minutes and one rule about rounding up - everything that decides whether a set feels custom.
The short answer
To find your NEEVANAILS size, measure the widest point of each nail bed in millimetres and match it to the XS-XL range on the size card; when you fall between two sizes, choose the larger one and file the sidewalls.

Measure width, not length
Press-on fit is decided by the width of the nail bed at its widest point. Lay a flexible tape measure or a strip of paper across the nail, mark both sidewalls, and read the millimetres. Do this for all ten nails - most hands need three or four different sizes across one set.
Match, then round up
Compare each measurement to the size ranges printed on the NEEVANAILS card and in the product page size guide. If a nail sits between two sizes, take the larger tip: a wide tip can be filed down at the sidewalls, while a narrow tip lifts because it never bonds to the outer edges.
Let the studio guess for you
Uploading a hand photo to the NEEVANAILS AI Stylist returns a starting size alongside the shape scores. Treat it as a shortlist, then confirm against your own measurements before checkout - you select a size per set in the cart.
