Method 1 — Soft ruler
Use the millimeter side of a soft ruler or measuring tape. Measure the widest part of each nail, edge to edge, and note every finger separately.
Fit guide
A quiet reference for press-on fit—widths in millimeters, length families, and a calm apply / remove flow. Measure once; wear with confidence.
Short reads everyday. Medium balances canvas and wearability. Long is for statement silhouettes—coffin and stiletto especially.

Widths are in millimeters at the widest point of each nail. If you fall between sizes, size up for comfort or down for a snugger edge.

Measure every finger—the set is only as secure as the closest width match.

Use the millimeter side of a soft ruler or measuring tape. Measure the widest part of each nail, edge to edge, and note every finger separately.

Press a strip of paper or tape across the nail, mark both side edges, lay the strip flat, then measure the gap with a ruler in millimeters.

Gently file the natural nail surface and wipe with alcohol so adhesive grips cleanly.
Choose the closest size for each finger and place the adhesive sticker on the natural nail.
Press the press-on from the cuticle (root) toward the tip so it seats evenly with no air pockets.
Hold firmly for about 10 seconds. Avoid water for 3–4 hours while the bond sets.
Soak nails in warm water for 5–10 minutes to soften the adhesive.
Use a wooden stick to ease under the free edge and lift slowly—never force or pry hard.
If a nail still feels tight, soak again before continuing instead of pulling.
Clean the natural nails and finish with cuticle oil to restore moisture.
