Getting the right size makes all the difference — both for how your press-ons look and how well they stay on. 💕

Nori & Co. nail sets come in four pre-sized options: XS, S, M, and L. Follow the steps below to find the best fit for you.

Step 1: Measure Each Nail in Millimeters

For the most accurate sizing, measure the widest part of each natural nail from sidewall to sidewall.

You can use either of these methods:

Option 1 — Measuring Tape Method (Recommended)

1. Use the millimeter (mm) side of a soft measuring tape.
2. Place it across the widest part of your natural nail, following the natural curve of your nail.
3. Read and record the measurement in millimeters.
4. Repeat for all 10 nails.

Tip: Don't assume both hands are exactly the same! It's completely normal for the same finger on each hand to have slightly different measurements.

Option 2 — Sticky Tape + Ruler Method

1. Place a small piece of clear tape across the widest part of your nail.
2. Press it down so it follows the natural curve of your nail.
3. Mark both edges of your nail on the tape with a pen.
4. Peel off the tape and place it flat on a piece of paper.
5. Measure the distance between the two marks in millimeters using a ruler.
6. Repeat for all 10 nails and record your measurements.

Step 2: Match Your Measurements to Our Tip Number Guide

Each press-on nail tip has a small number underneath that corresponds to its width.

Once you've measured all 10 nails, compare your measurements with our Tip Number Guide below to find the closest matching tip for each finger.

Measure the widest part of each natural nail and compare it with the measurements shown in the chart.

All measurements are in millimeters (mm).

✨ A Few Important Sizing Tips

• Choose the pre-sized set that matches most of your fingers.
• If you're between two tip sizes, we generally recommend sizing up. A slightly larger nail can be gently filed along the sides for a more customized fit.
• Consider sizing up if you have flatter or wider nail beds, as nail curvature can affect how a press-on fits even when the width measurement appears correct.
• Never choose a nail that feels too small or needs to be forced onto your natural nail.
• Measure all 10 nails for the most accurate result.

Step 3: Double-Check Your Fit

A properly fitted press-on should cover your natural nail from sidewall to sidewall without sitting on or overlapping the surrounding skin.

The nail should feel comfortable and follow the natural shape of your nail bed.

If a press-on is slightly too wide, you can gently file the sides until it fits your natural nail more closely.

If it's too narrow and doesn't fully cover your natural nail from side to side, you'll need a larger tip.

Please Double-Check Your Size Before Ordering 🤍

Each Nori & Co. set is handcrafted and pre-sized according to our standard XS, S, M, and L size guides.

Everyone's natural nails are unique in width, shape, and curve, so even with careful measuring, slight variations in fit can happen.

We strongly recommend measuring your nails and checking our size chart carefully before placing your order.
