The perfect Karève set starts with the right fit.
Every natural nail is different. Measuring your nails correctly helps us create a comfortable, seamless fit for your Karève press-ons. Choose whichever method is easiest for you.
Measure your nails
What you'll need: a soft measuring tape, or a thin strip of paper with a ruler and a pen.


Find the widest point
Measure across the widest part of your natural nail, from one side to the other. Do not measure the length of your nail.
Measure in millimetres
If you are using paper, place the strip across your nail and mark where each side ends. Remove the paper and measure between the two marks with a ruler. Record your measurement in millimetres.
Measure all 10 nails
Measure each nail individually, and measure your left and right hand separately. The same finger can have a different measurement on each hand, and that is completely normal.
Find your size
Compare your measurements with the Karève size chart below. Pick your shape, then match your widest nails to the numbers in the table.
If your measurement falls between two sizes, choose the larger size. A slightly larger nail can be gently filed for a better fit, while a nail that is too small will not fully cover your natural nail.
No ruler? No problem.
Our 1-dirham photo method
All you need is a 1 UAE dirham coin and your phone. We'll help you find your size.

Four fingers
Place a 1 dirham coin beside your hand and take a clear photo of your four fingers, excluding your thumb. Keep your fingers straight and relaxed.
Your thumb
Take a separate photo of your thumb with the same coin beside it. Make sure your thumb is lying flat.
Send us your photos
Send them to us on WhatsApp or by Instagram DM. We'll use the coin as a reference to determine your measurements and recommend the best Karève size for you.
For the most accurate result
- Use good, natural lighting
- Keep your fingers straight
- Keep your hand flat
- Place the coin beside your nails
- Take the photo from directly above
- Make sure the image is clear and not blurry
- Remove nail polish first, if possible
The Karève size chart
Choose your shape first. Each chart shows every nail with its width in millimetres, and the table underneath tells you which nails make up each size. The number is the nail, the width is the widest point of your natural nail.
