How to Measure Your Nails
- 📏 Find the widest point. Look at the widest part of each nail, from one side to the other.
- 🧵 Use a flexible tape. Measure across the nail’s widest point, following its natural curve.
- 📝 No flexible tape? Wrap a strip of paper over the nail, mark both edges, then lay it flat and measure between the marks with a ruler.
- ✅ Match your measurements. Measure each finger in millimeters and compare the widths with the size chart below.
