How to Measure for Press-On Nails: A Simple Size Guide

To measure for press-on nails, record the width of each natural nail at its widest point in millimetres. A careful measurement helps you choose a comfortable set and reduces the amount of filing needed before application.

Flechazo Nail Studio creates handmade press-on nail sets in small batches. Because each available set is listed individually, checking the size before ordering is the best way to find a design that works for your nails.

What you need to measure your nails

Use a soft measuring tape marked in millimetres. If you do not have one, place a small strip of clear tape across the widest part of your nail, mark both side edges, and measure the distance with a ruler.

How to measure your nails step by step

1. Start with clean, natural nails without polish or adhesive residue.
2. Measure across the widest part of each nail from sidewall to sidewall.
3. Write down the width in millimetres for your thumb, index finger, middle finger, ring finger, and pinky.
4. Repeat the process for your other hand if your nail widths differ.
5. Compare your measurements with the size information shown on the product page.

What if you are between press-on nail sizes?

If you are between sizes, choose the slightly larger nail. A press-on nail that is a little wider can usually be refined with gentle filing along the side edges. A nail that is too narrow may feel uncomfortable and may not sit naturally on the nail plate.

How should press-on nails fit?

A good fit should cover the natural nail from side to side without pressing into the skin. Before applying adhesive, lay out all ten nails in finger order and check that each piece sits comfortably at the cuticle line.
