Fit guide
Learn how to size press-on nails from sidewall to sidewall, what to do when you sit between sizes, and how to recognise a fit that is too tight or too wide.
Quick answer
The best size covers the visible nail plate from sidewall to sidewall without pressing into skin. Compare neighbouring sizes before applying; a piece that sits flat is usually a better starting point than one that must be forced into place.
NAILINK EVERYDAY fit reference
Each EVERYDAY box contains 24 press-on nails across 12 numbered sizes, with two pieces of each size. The chart dimensions differ by shape, so use the row for the shape on the product rather than carrying one size number across every profile.
The ranges below summarise the smallest and largest pieces in each current chart. Width is a useful starting point, but curvature still decides whether a piece can rest evenly. Dry-fit the actual piece and compare its neighbour before applying adhesive.
| Shape | Included sizes | Chart width span | Chart length span |
|---|---|---|---|
| Short Almond | #0–#11 | 5–13.8 mm | 11–16.6 mm |
| Extra Short Oval | #0–#11 | 7.6–14 mm | 17–21.5 mm |
| Short Oval | #0–#11 | 6–13.2 mm | 14–20 mm |
| Short Square | #0–#11 | 6.2–14 mm | 13–17.4 mm |
If two pieces look close, compare both. Choose the piece that covers the visible nail plate, sits flat without rocking and does not press into skin. A slightly wider piece may be refined carefully at the side edge before application; a narrow piece cannot add missing coverage.
Press-on size numbers are useful for keeping a set organised, but the real test is how each piece meets your nail. Place an unglued press-on over the natural nail and look straight down. It should cover the visible nail plate from one sidewall to the other without resting on the surrounding skin.
Check every finger independently. The same numbered size may not suit the same finger on both hands, and thumbs often need the most careful comparison. Keep the pieces laid out in right-hand and left-hand order once you have chosen them.
Compare the neighbouring sizes before reaching for a file. If the smaller piece leaves a visible strip of natural nail or feels as though it is squeezing the sides, try the larger piece. A slightly wider piece can be refined carefully at the side edge, but a piece that is too narrow cannot make full, relaxed contact.
Make any adjustment before applying adhesive. Use a fine nail file at the side edge, take off very little at a time and keep checking the fit. Do not thin the centre of the press-on or file aggressively around the natural nail.
Shape and curvature matter as well as width. If several sizes all rock or pinch, that style may not match your nail curve. A shorter, softer-flex profile can reduce leverage in daily use, but it still needs a compatible fit.
Once all ten sizes are arranged, wash and dry your hands and remove surface oil with the supplied alcohol prep pad. Match each jelly tab to the natural nail, smooth it flat, then position the selected press-on close to—but not on—the cuticle.
Sizing first prevents a common problem: preparing one finger, applying immediately and discovering later that a neighbouring piece would have sat better. A few extra minutes of dry fitting usually makes the complete set easier to apply.
Frequently asked questions
Choose the piece that covers the nail from sidewall to sidewall without pressure. If the smaller size pinches or leaves the side exposed, use the next size and carefully refine its side edge before application if needed.
You can make a small adjustment at the side edge with a fine file before applying. Remove very little at a time and keep checking the fit rather than reshaping the whole piece.
A width or curvature mismatch, skin contact, surface oil or a folded adhesive tab can all interrupt contact. Recheck the dry fit and preparation instead of adding force.
