Nail Size Guide

Because fit matters — especially when it’s on your fingertips.

💡 How to Find Your Perfect Fit

No measuring tape? No problem.
Here is one easy way to make sure your LUNE nails fit like a dream:

✋ The Ruler Method (Quick & DIY)

1. Grab a millimeter ruler (the small kind — we believe in precision).

2. Measure the widest part of your natural nail bed — side to side.

3. Do it for all 10 fingers — yes, thumbs too.

4. Match your numbers with our sizing chart below.

✨ Pro Tip: If you're between sizes, go slightly bigger. Too big = use your nail file to make it small. Too small = awkward.

Measurements may vary slightly depending on nail shape. We’re not robots.

🧩 Can't Decide?

Email us your ruler pic at hello@lunenail.com and we’ll help match you.
Because the only thing worse than too-tight jeans is a too-big pinky nail.
