Cross-Brand Width Comparator
Enter a nail width in millimeters and inspect the nearest recorded references inside source snapshots we have actually verified. The tool compares measurements, not brand size labels, and keeps different manufacturer measurement bases plus system-level calculator ranges visibly separated.
Manufacturers do not always publish the same kind of width. Glamnetic and Olive & June Pressies publish dimensions of press-on sizes, while MOONLEE explicitly labels its values as nail-bed widths for preset finger sizes. Rows are therefore sorted only inside the same source-basis group. A smaller numeric delta across two different groups is not a cross-brand winner and is never a fit guarantee.
Enter a width to inspect source-dated references.
The tool never converts a Glamnetic size number into a MOONLEE or BTArtbox size number. It compares recorded millimeter references while keeping different manufacturer measurement conventions visibly separated.
How to use a result without over-trusting it
Use a nearby recorded number as a research shortlist, not as an automatic size assignment. A 10.2 mm natural nail, a manufacturer's 10.2 mm nail-bed target, and a press-on charted at 10.2 mm are not automatically equivalent. C-curve, sidewall geometry, cuticle shape, material flexibility, and the source measurement convention can all change the fit.
If two nearby candidates look plausible, open the official source and the brand sizing rule before choosing. The width comparator intentionally does not apply a universal “size up” or “size down” rule because current manufacturers publish different instructions.
