Measure Your Nail Width
Use a soft ruler or paper strip to measure the widest part of your nail (near the base).
Check the Size Chart
XS:10-11
S: 11-12mm
M: 12-13mm
L: 13-14mm
XL: 14-15mm
Choose the Right Fit
If your nail width falls between two sizes, choose the larger one and file slightly for a perfect fit.
Tips
For short or curved nails, oval or square styles work best for a natural look.
