Measure the widest point of each nail with a soft measuring tape or a strip of paper, then compare that number to the sticker width before you peel anything off the sheet.
Nails are rarely uniform. Your thumb is usually the widest, your pinky the narrowest, and the same finger on your left and right hand can differ by a millimeter. Because of that, sizing should be done finger by finger rather than assuming one size fits all ten nails.
If you are between two sizes, always choose the larger one. You can trim excess material in seconds, but you cannot add width back to a sticker that is too small.
A sticker that is too big overlaps your cuticle and sidewalls, and that overlap is the number one cause of early lifting.
Nail stickers adhere to the nail plate, not to skin. When the edge sits on your cuticle or the skin beside your nail, natural oils and movement work under it, and the sticker starts peeling within a day or two — long before its normal wear time. Oversized stickers also wrinkle at the sides when you press them down, which traps air and looks uneven.
The fix is simple: place the sticker slightly off-center if needed, then trim the overhang with small curved scissors or a fine nail file held at a downward angle. Trim before you press the edges down firmly, so you get one clean seal instead of a lifted edge you have to re-smooth.
A sticker that is too small leaves bare nail visible at both sides, and no amount of pressing will fix it — you need to size up.
Undersized stickers expose the natural nail along the sidewalls, which looks like a gap and gives water and soap a path underneath. That gap also makes the sticker more likely to catch on things and lift from the corner. Since stickers do not stretch, the only real solution is to move up to the next width.
If the next size up is too wide, trim it down. This is why sizing up and cutting back is the safer direction: a trimmed sticker still has a clean, sealed edge, while an undersized one never will. For a wide range of widths and finishes to choose from, FingerFox nail art stickers come in 107 designs so you can match both the size and the look you want.
Stickers are more forgiving on size because you can trim them; press-on nails need a closer match because they are rigid and cannot be reshaped as easily.

| UV lamp needed | No | No |
| Drying time | None | None |

| Price range | $1.45–$15.95 USD | $1.45–$15.95 USD |
If your nails vary a lot in width from finger to finger, stickers give you more room for error. If you want a structured, salon-style shape, press-ons are the better pick — just measure carefully first. You can browse all 107 designs to see both formats side by side.
Clean, dry, oil-free nails plus a top coat are what turn a correctly sized sticker into a 7–14 day manicure.
The finished result is waterproof for hand washing and showers, and removal takes only warm water and cuticle oil — no acetone required. Orders over $25 ship free (otherwise $4.99) from an overseas warehouse with 7–14 business day delivery, so it helps to measure and order the right sizes in one go.
Always size to the widest part, which is usually just above the tip rather than at the cuticle. If you size to the narrowest point, the sticker will be too small at the sides and leave visible gaps.
Yes. Trim the sides with small curved scissors or a fine nail file before pressing the edges down firmly. Cut slightly outside your target line and file inward so you do not accidentally remove too much.
Move up to the next size and trim the excess, since stickers do not stretch and an undersized one leaves exposed nail at the sidewalls. Sizing up and cutting back always produces a cleaner seal than trying to stretch a small sticker.
With a clear top coat sealing the edges, FingerFox nail art stickers wear for 7–14 days and stay waterproof through hand washing and showers. Oversized stickers that touch skin typically lift much sooner, which is why the 0.5–1 mm margin matters.
