Sizing Guide
To order press-on set from @thatprettynail, you’ll need to know your nail measurements to ensure the perfect fit.
I recommend 2 options:
1. Purchase a Sizing Kit
The most accurate way to find your fit! You can order a sizing kit directly from my Etsy shop.
2. Measure Your Nails at Home
Don’t have a sizing kit yet? No problem! You can measure your nails using the tape method.
Here is how to determine your size:
You’ll need:
- A measuring tape, a piece of paper OR
- Clear tape
- Ruler (with millimeters)
- Pen or marker

Step 1: Using transparent tape, place it across the largest part of your nail pulling down tight to account for any curve of your nail.
*Note the width of each nail in milimeters for each finger, at the widest part.
Step 2: Mark the 2 sides of your nail on the tape with a pen.
Step 3: Remove the tape and measure it with a ruler.
Step 4: Measure each nail. Choose your the referable nail shape and compare with charts below to determine your individual nail numbers (00-9). Remember to use Inner Curvature (IC) size.
Once you’ve determined your nail size, you can:

TIPS:
*** Don’t forget to include your pen marks in your measurements (it will add an extra 2-3mm to your actual size).
*** It’s always better to size up than down so you can file away the edges for a better fit but can never add material back!
***Don’t forget to check both hands – lots of times nails on one hand may be different sizes!
