How to Measure Your Nails at Home (Step-by-Step)
Finding the perfect fit is key to making your press-on nails look flawless and feel comfortable. At SirenShimmer, we offer a variety of sizes, but to get that custom-salon look at home, you need to know your exact nail measurements. Don’t worry—it’s super easy and takes just a few minutes. Here's a step-by-step guide to help you measure your nails accurately from the comfort of your home.
🌟 Why Nail Sizing Matters
Ill-fitting press-on nails can pop off too easily or feel uncomfortable. When you know your exact nail sizes, you’ll get:
-
A snug, natural fit
-
Longer-lasting wear
-
A more seamless, salon-quality finish
Let’s get started!
✂️ What You’ll Need:
-
A flexible measuring tape (tailor’s tape) or a strip of paper
-
A fine-tip pen or marker
-
A ruler (in millimeters)
-
A flat surface and good lighting
📏 Step-by-Step Guide
Step 1: Prep Your Nails
-
Make sure your natural nails are clean and dry.
-
Remove any nail polish or oils for the most accurate fit.
Step 2: Wrap and Mark
If using a tape measure:
-
Wrap the tape across the widest part of your natural nail (usually across the middle).
-
Record the width in millimeters (mm).
If using a strip of paper:
-
Cut a thin strip of paper (about 5mm wide).
-
Wrap it around the widest part of your nail.
-
Use a pen to mark where the paper overlaps.
-
Lay it flat next to a ruler to measure the distance in millimeters.
Step 3: Measure Each Finger
-
Measure all 10 nails—each one can be slightly different.
-
Note the measurements for both hands. (Some people have size differences between their left and right hands!)
✍️ Optional: Use a Sizing Kit
