Perfect Fit Every Time: The Ultimate 2-Minute Guide to Measuring Your Nails

A common question we get is: "How do I know which size to order?" The difference between a press-on that looks "fake" and one that looks like an expensive salon gel set is the fit. At TsukiNails, we want you to have that flawless, seamless look. Here is the easiest way to measure your nails at home using items you already have.

What You’ll Need:

  • A piece of clear tape

  • A pen or marker

  • A ruler (with millimeter markings)

Step-by-Step Instructions:

  1. The Tape Method: Place a piece of clear tape across the widest part of your natural nail bed. Make sure it's flat and covers both side walls.

  2. Mark the Edges: Use your pen to mark the exact points where your nail meets the skin on both sides.

  3. Measure the Millimeters: Remove the tape and lay it flat against your ruler. Count the millimeters between the two marks.

    Pro Tip: When in Doubt, Size Up
    If you are between sizes, we always recommend sizing up. It is much easier to gently file down the edges of a slightly larger nail than to try and fit a nail that is too small!

    Conclusion
    Measuring only takes two minutes but ensures a lifetime of beautiful manicures. Now that you have your sizes, you’re ready to find your dream set.
