First Measure your nails.
Please be aware that there is more room for error when measuring your nails versus using the coin method or a sizing kit, and could lead to you ordering nails that do not fit correctly.
How to Measure your Nails in Millimeters:
Step 1
Lay a soft measuring tape over the widest part of your nail pulling down tight to account for any curve of your nail.
Note the width of each nail in millimeters for each finger, at the widest part.
OR
Stick a piece of tape across the widest part of your nail pressing down to account for any curvature.
Pull the tape off your nail and measure the distance between your marks of each nail (thumb, index, middle, ring and pinky) with a measuring tape or ruler in millimeters. You can even add your measurements to the form below as you measure! (recommend)
Step 2
Now that you've recorded the width (accounting for any curve) of your nails in millimeters, imput into the form your sizes in mm.
