Sizing Kits for each Length & Shape are available & are the best way to get a 100% perfect fit.
If your nails do not match the standard set sizes select "Custom" & enter your measurements in the notes section.
Once you select your nail bed measurements, you can pick your favorite length & shape in the drop down menu. You can check out the photo gallery for reference, where a penny is compared to the largest thumb size 0, with the length measured in millimeters next to each size. If you don't see the length or shape you're looking for, feel free to send me a message.
