How to Measure for a Full Lace Wig That Fits Perfectly
A wig that doesn't fit is a wig that doesn't work. After 21 years fitting clients, I can tell you: most wig problems stem from incorrect sizing, not the wig itself. Too loose, it slips. Too tight, it causes headaches and scalp pain. This guide walks you through measuring yourself accurately so your full lace wig fits like it was custom-made for you.
PART ONE: WHY MEASUREMENT MATTERS
Before you buy, measure. Before you apply adhesive, measure again. Proper measurement prevents:
- Slipping during normal wear or activity
- Headaches and scalp pain from over-tightening
- Gapping along the hairline (visible construction)
- Discomfort after 2-3 hours of wear
- Lace tearing from struggling with bad fit
- Wasted money on returns
A wig is only as good as its fit. Quality hair and beautiful construction mean nothing if the wig won't stay on your head.
PART TWO: THE FOUR CRITICAL MEASUREMENTS
Measurement #1: Head Circumference
What it is: The distance around your head at the widest point.
Why it matters: Determines if the cap will be too loose or too tight.
How to measure:
- Use a soft measuring tape (not rigid)
- Place tape at your hairline (about 1 inch above your eyebrows)
- Wrap around back of head, returning to starting point
- Keep tape snug but not tight
- Take note of measurement in inches
Standard sizes:
- Small: 20-21 inches
- Medium: 21-23 inches
- Large: 23-24 inches
- Extra Large: 24+ inches
Most people are medium (21-23 inches). If you're between sizes, opt for the larger size—adjustable straps can make it tighter.
Measurement #2: Hairline to Nape
What it is: Distance from your hairline to the bottom of your neck.
Why it matters: Determines wig length and front-to-back sizing.
How to measure:
- Sit upright with posture straight
- Measure from hairline down to where wig should end at nape
- For most wigs, this is 14-16 inches
Measurement #3: Ear to Ear (Across Forehead)
What it is: Distance from ear to ear, across your forehead.
Why it matters: Determines front hairline placement width.
How to measure:
- Measure from point above one ear to above the other
- This is typically 11-13 inches
Measurement #4: Temple to Temple (Around Back)
What it is: Distance from temple area, around back of head.
Why it matters: Determines side and back fit.
How to measure:
- Measure from temple, around back of head to opposite temple
- This is typically 18-20 inches
PART THREE: WIG CAP SIZING OPTIONS
Adjustable Cap System
Most full lace wigs feature adjustable straps in the back that tighten or loosen. This allows one wig to fit head circumferences of 21-24 inches by adjusting straps.
Pros: Flexibility, one size fits multiple heads
Cons: Straps can be visible if worn in high buns
Custom-Sewn Cap
Some high-end wigs can be custom-sewn to exact specifications. Requires precise measurements and custom order process.
Pros: Perfect fit for your exact head
Cons: Expensive, takes 2-4 weeks, non-returnable
Standard Size
Choose small, medium, or large based on your head circumference. Works if you're clearly within one size range.
Pros: Affordable, immediate availability
Cons: Less flexibility if you're between sizes
PART FOUR: COMMON FIT PROBLEMS & SOLUTIONS
Problem: Wig slips even with straps tightened
- Solution: Wig is too large. Try smaller size or use wig grips/combs for security.
Problem: Headache after 1-2 hours
- Solution: Wig is too tight. Loosen straps, ensure you're not over-tightening glue adhesive.
Problem: Gaps along hairline
- Solution: Wig is too loose or not positioned correctly. Remeasure and reposition.
Problem: Uneven fit (higher on one side)
- Solution: Check if your head is symmetrical. Some people have naturally uneven head shapes. Use wig grips on the loose side.
Problem: Neck pain after wearing
- Solution: Back straps may be pulling too tight. Loosen slightly or adjust placement.
