Place the tape
Place a strip of tape across the widest part of your natural nail. Follow its curve without stretching the tape.
YOUR FIRST SET STARTS HERE
Find your perfect fit.
Measure your nails, compare your measurements and choose your set with confidence.
BEFORE CHOOSING YOUR SET
Three steps to find your size.
You need clear adhesive tape, a pen and a ruler marked in millimetres.
Mark the edges
Mark both sides of the nail on the tape. Measure the width from side to side, not the nail length.
Read the millimetres
Remove the tape and lay it flat on the ruler. Record the distance between the marks and repeat for every finger.
FIND YOUR FIT
Find your KKB size.
Compare your measurements with the KNOCK KNOCK chart. Also check the size options for the design you want to buy.
| Size | Thumb | Index | Middle | Ring | Little |
|---|---|---|---|---|---|
| S | 15 | 11 | 12 | 11 | 9 |
| M | 16 | 12 | 13 | 12 | 10 |
| L | 17 | 13 | 14 | 13 | 11 |
This chart is for KNOCK KNOCK nails. Do not use another brand’s chart to choose your set.
A LITTLE EXTRA HELP
Before you buy.
A good fit starts with an accurate measurement.
Should I measure width or length?
Measure the width, from side to side across the widest part of the nail. The tape should follow its natural curve.
Do I need to measure every finger?
Yes. Measure all five fingers on both hands and record them separately. Do not assume both hands have the same measurements.
What if my measurements do not match a size?
Measure again and check the design’s chart. If you are still unsure, contact us with your measurements before ordering.
Where can I learn how to apply them?
