Choose the pre-set size that fits most of your nail beds
Consider sizing up if you are between two sizes
If a size fits all fingers perfectly but is too small for your thumb, go up a size as it will provide a better overall fit
If none of the pre-options comes close to your nail size, select 'CUSTOM' and include your measurements from thumb to pinky in the 'special notes' during check out (e.g. 0, 4, 4, 5 8)
Method 1 | Measuring Tape
Find the widest part of your nail bed.
Using a flexible measuring tape (in millimeters), measure the widest part of each nail bed. Note down your measurement and repeat for each nail.
Compare your nail measurements to the sizing guide. For example, if your measurements are 1, 5, 4, 6, 8, you would select medium size since these measurements align most closely with the medium sizing guide.
Method 2 | Sticky Tape
Place a piece of sticky tape over your nail bed. If you don't have sticky tape, you can also use a piece of paper.
Mark the widest part of your nail bed with a pen or marker.
Remove the tape from your nail. Using a ruler (in millimeters), measure the widest distance between the two marked lines on the tape. Note down your measurement and repeat for each nail.
Compare your measurements to the sizing guide above. For example, if your measurements are 0, 4.5, 3, 4, 7, you would select large size since these measurements align most closely with the large sizing guide.
Method 3 | Sizing Kit
A sizing kit is the most accurate way to determine your nail size:
Order a sizing kit which includes clear plastic sizing nails
Try each nail tip on your natural nail bed
Select the size that covers your entire nail bed from side wall to side wall
Make note of the correct size number for each finger
Use these exact size numbers when ordering your press-on nails for a perfect fit!
The sizing kit allows you to physically test different sizes on your nails, ensuring the most accurate fit possible.
