How to Make Press On Nails Last Longer – Pro Tips
On
How to Make Press On Nails Last Longer starts with the right preparation and care. Shopping for premium Kentrim handmade press-on nails? Getting incorrect sizing is the No.1 reason for returns, uncomfortable wear, and early nail lifting. Many shoppers blindly pick standard S/M/L sizes based on guesswork, only to receive press-ons that slide off, pinch cuticles, or leave exposed nail gaps after application.
As a handmade luxury press-on nail brand, Kentrim crafts every manicure set with precise sizing standards. Learning how to accurately measure your natural nail width at home takes less than 5 minutes, helps you match the ideal size from our official size chart, cut wrong-size returns drastically, and enjoy salon-perfect fit from your Kentrim press-on collection.
2 Easy DIY Measurement Methods at Home
Method 1: Transparent Tape Measuring（Most Recommended, No Ruler Needed）
Best for customers without a millimeter ruler, matches our step-by-step illustration.
- Lay a strip of clear adhesive tape flat across the widest horizontal spot of your natural nail, press smoothly against nail surface without stretching the tape.
- Use a fine-tip pen to mark the left and right edge of your nail directly onto the tape. Do not mark outside your actual nail borderline.
- Peel off the marked tape carefully and stick it on a flat table.
- Use a millimeter ruler to check the distance between two marks; this number is your nail width in mm.
- Repeat the same process for all 10 fingernails separately, record every size down.
Method 2: Direct Ruler Measuring（Fastest Option）
- Place a metric ruler (marked in mm) horizontally across the widest part of your bare natural nail.
- Align ruler zero mark with one nail edge, read the exact mm number at the opposite side.
- Note measurements for thumb, index, middle, ring and pinky finger one by one.
Core Tip: Always measure natural nails without existing nail polish or old fake nails on.

Common Sizing Mistakes to Avoid (Key to Reduce Returns)
- ❌ Measure near cuticle or nail tip: Only measure the widest middle part of natural nail, cuticle/tip measurement leads to undersized or oversized nails.
- ❌ Measure curved nail surface: Keep ruler/tape horizontal and flat, curved reading causes wrong mm data.
- ❌ Assume all fingers share same size: Most people have mismatched nail width between fingers; mixed-size selection is available for all Kentrim orders.
- ❌ Measure nails after hand swelling: Measure at room temperature when hands are in normal status, avoid measuring right after hot bath or exercise.
What If Your Nail Width Falls Between Two Sizes?
If your measurement sits between two listed sizes on Kentrim chart, always choose the smaller option:
- Oversized press-on nails will overlap your skin, lift easily during daily work and cause premature falling off;
- Slightly smaller Kentrim nails sit perfectly within your nail bed for stable, long-lasting wear.
