Nail Size & Fit Guide
Finding Your Perfect Press-On Nail Size
Trilumity press-on nail sets typically include 10–24 tips per box, covering multiple sizes so you can find the closest match for each of your 10 nails. Getting the right fit is the key to a comfortable, long-lasting, salon-like manicure.
How to Measure Your Nails
- Measure the width of your natural nail bed (cuticle to cuticle) at its widest point, side to side.
- Compare your measurement to the size chart below for your closest match.
- If a tip is slightly too wide, gently file the sides down for a custom fit. Avoid sizes that are too narrow — they can pinch or lift.
| Size | Approx. Width | Typical Finger |
|---|---|---|
| 0 (XS) | 10mm | Pinky |
| 1 | 11mm | Pinky / Ring |
| 2 | 12mm | Ring |
| 3 | 13mm | Ring / Middle |
| 4 | 14mm | Middle |
| 5 | 15mm | Middle / Index |
| 6 | 16mm | Index |
| 7 (XL) | 17mm+ | Thumb |
Choosing a Length & Shape
- Short / Medium: Best for everyday wear, typing, and an easy first-time press-on experience.
- Long: A dramatic, glam look for special occasions.
- Shapes: Almond and coffin lengthen the fingers; square and round offer a natural, low-maintenance look.
Application Tips for the Best Fit
- Push back cuticles and gently buff the natural nail surface.
- Select the closest-size tip for each finger before applying adhesive.
- Apply the adhesive tab or glue, then press firmly for 10–20 seconds at a slight angle from cuticle to tip.
