Press-On Nail Size Guide: Fit, Glue & Wear

A set fits when three things line up: width, curve and length. Most size guides only cover the first one. This one covers all three.

Find your size: measure your nails and enter the widths ↓

1. Start with the width check

The best size covers your natural nail from side to side without touching the skin. If one size feels slightly wide and the next feels slightly narrow, start with the smaller size and lightly file the sides.

  • Measure every finger. Your left and right hands may need different sizes.
  • Dry-fit each nail before you reach for glue or tabs.
  • Starter kits and special packs vary, so check the product’s kit details before buying.

Find your size

Measure each nail in millimetres, enter the widths, and see the size number for every finger in each of our sets. The numbers come from the size tables on this page.

How to measure your nails

  1. Print the ruler. Print it at 100% scale (“Actual size”). Then hold a bank card over the card outline: they should match exactly (85.6 × 54 mm). If they don’t, your printer scaled the page. Change the setting and print again.
  2. Or use a strip of tape. Press a thin strip of clear tape across your nail, mark both side edges with a pen, peel it off and measure the distance between the marks on the ruler.
  3. Measure the widest part. Go straight across the nail at its widest point, from one side edge to the other, where the nail meets the skin.
  4. Measure every finger on both hands. Left and right hands often differ. Write each width down as you go.

Pick your shape, then the length, to see the tip measurements for that set. These are the mold specifications for our sets, grouped by shape. Use them to compare sizes within a set — then dry-fit before applying.

3. Check the curve

Width is only the first check. The curve across your nail decides whether a tip sits flat or rocks.

Dry-fit with no adhesive. Place the tip on your nail. If it rocks, lifts in the centre, or pinches at the edges, the curve is the mismatch — not the width. Keep the nail centred and press from cuticle to tip when you do apply it.

4. Shape, taper and length

Shapes differ in more than looks. Square and coffin tips keep close to their full width along the nail and finish with a flat tip. Almond and oval tips taper, so the widest point sits nearer your cuticle. Duck tips flare wider at the end.

Length varies too — and it varies within a shape. Two sets can share a shape, and nearly the same width, and still differ by several millimetres in length. That is why the charts above are per set rather than per shape.

If a tapered set feels wrong on your fingers even at the right width, a straighter-sided shape is worth trying. The reverse is equally true. Fit is personal, and the dry-fit is how you find yours.

If it doesn’t fit

What you notice Likely cause What to try
Presses into the skin at the sides Too wide Next size down, or file the sides
Visible gap at the sides Too narrow Next size up
Rocks, or lifts in the centre Curve mismatch Re-centre and press cuticle to tip. If it happens on most fingers, try another shape
Fine at the base, wrong past the fingertip Length Same shape, shorter set — or file the length
Good on some fingers, not others Normal variation Mix sizes across fingers. That is what the size range is for

Choose your wear mode

Adhesive tabs: best for quick changes, short wear, events, and easy removal.
Nail glue: best when you want a stronger hold and longer wear.

For the strongest hold, clean and dry each nail, avoid lotion before application, press each nail for about 30 seconds, and avoid soaking hands for the first 2 hours.

Light filing is normal

A light side file or length file can make the set feel more custom. File gently before application, then wipe away dust before applying tabs or glue.
