The secret to press-on nails that look natural and last all week? The right fit. A press-on that's too wide will lift at the edges; one that's too narrow leaves gaps. Getting your sizing right takes two minutes and makes all the difference. Here's exactly how to do it.

Why Sizing Matters

Unlike acrylic nails shaped to your nail bed, press-ons come in a fixed set of sizes. The goal is to find the press-on that covers your nail from sidewall to sidewall — edge to edge — without sitting on your skin. Skin contact breaks the adhesive bond and causes early lifting. A well-fitted nail will feel snug, lay flat, and look completely seamless.

Method 1: Measure with a Tape Measure or Ruler (Most Accurate)

1. Hold a flexible tape measure or a small ruler across the widest part of your nail, just above the cuticle.
2. Note the width in millimetres for each finger.
3. Write down all 10 measurements — your dominant and non-dominant hands are often slightly different.
4. Match each measurement to the closest size in your Faked It nail set. When in doubt, size down.

Method 2: Use Paper Strips (No Ruler Needed)

1. Cut a thin strip of paper and press it across the widest point of your nail.
2. Mark the width on the paper with a pen.
3. Lay the paper strip against a ruler and note the measurement in millimetres.
4. Repeat for each finger and match to your set's sizing guide.

Method 3: Test Fit the Press-Ons (Quick & Easy)

If you already have your Faked It set in hand, this is the fastest method. Before applying any glue or adhesive, hold each press-on over your natural nail. It should cover the full width of your nail without any skin showing under the sides. Work through your set for each finger, lay them out in order, and you're ready to apply. This method works well for most people and lets you account for any slight asymmetry between fingers.

Sizing Tips

• Always size down if between sizes. A slightly narrower nail sits flush; a slightly wider one will lift.
• Your thumb takes the largest size, your pinky the smallest — but middle fingers sometimes surprise you.
• Keep a record of your sizes. Once you know your sizing, reordering is effortless.
• Nail shape matters too. If your natural nails are very curved, a slightly narrower press-on will lay flatter and more comfortably.

Common Sizing Mistakes

• Measuring the cuticle instead of the nail plate — measure the exposed nail, not the skin
  
• Choosing a wider size to avoid filing — this always leads to lifting

What Happens If a Nail Doesn't Fit?

If none of the included sizes is quite right, you can gently file the sides of the press-on with a fine nail file to narrow it slightly. Work in small increments and test-fit frequently. Avoid filing too aggressively, as this can weaken the nail at the edges.
