Choosing the right size of press-on nails is the most important step for a natural result and optimal hold. At MB Beauty, you choose your size when ordering and receive a complete kit tailored to your hand. Here's how to find your perfect size in less than 5 minutes.
How does the MB Beauty sizing system work?
Unlike some brands that deliver several sizes in one kit, at MB Beauty each set is manufactured in a single size — XS, S, M, or L. You choose your size when ordering and receive 10 perfectly sized nails for each finger of your hand. That's why it's important to measure carefully before ordering.
How to measure your nails?
Use a small measuring tape or a millimeter ruler. Measure the width of each natural nail at its widest point, usually in the middle of the nail. Note the measurement in millimeters. That's it — no special equipment needed.
The MB Beauty size guide
Compare your measurements with this chart to find your size:
- Thumb: XS = 14 mm · S = 15 mm · M = 16 mm · L = 17 mm
- Index finger: XS = 10 mm · S = 11 mm · M = 12 mm · L = 13 mm
- Middle finger: XS = 11 mm · S = 12 mm · M = 13 mm · L = 14 mm
- Ring finger: XS = 10 mm · S = 11 mm · M = 12 mm · L = 13 mm
- Pinky finger: XS = 8 mm · S = 9 mm · M = 10 mm · L = 11 mm
A variation of 1 to 2 mm is possible depending on your morphology. If in doubt between two sizes, always choose the larger one for more comfort.
3 tips to find your size quickly
Tip 1 — The paper method (30 seconds)
No ruler handy? Place your finger on a sheet of paper and draw a line on each side of the nail at its widest point. Then measure the space between the two lines with any ruler. Simple, fast, and accurate.
Tip 2 — Trust your thumb
To choose a single size for the entire kit, prioritize measuring your thumb — it usually determines your overall size. If your thumb is 15 mm, choose S; 16 mm, choose M; 17 mm, choose L.
Tip 3 — When in doubt, go up a size
A slightly larger nail can be discreetly filed down on the sides to fit perfectly. Conversely, a nail that is too small will be uncomfortable and detach more quickly. When you hesitate between two sizes, always choose the larger one.
