Option 2: Measure at Home

If you'd like to measure yourself, here's how:

Place the tape across the widest part of your nail.
Mark where your nail bed starts and ends (corner to corner).
Remove the tape and measure the distance in millimeters with a ruler.
Match your measurements to our standard size chart below.
It is completely normal if your sizes do not perfectly match the standard sizes. In that case, instead of choosing a standard size; click "custom" and type in your mm measurements from Thumb to Pinky for each hand.
