How to Measure Wig Length Correctly
If you’ve ever ordered a wig online and felt it looked shorter or longer than expected, you’re not alone. Understanding how to measure wig length correctly is crucial to getting the perfect style and achieving the look you want. At TrendyHair Vietnam, we use precise industry standards when measuring our 100% Raw and Virgin Vietnamese Human Hair Wigs, ensuring every client gets what they expect — from root to tip.
1. Why Knowing How to Measure Wig Length Correctly Matters
Before we go into details, let’s understand why this matters so much.
Incorrect measurement can make your 24-inch wig look like an 18-inch one, especially for curly textures. Each curl pattern affects visual length, so using the right method helps you order confidently without surprises.
When you learn how to measure wig length correctly, you’ll always get the ideal balance between natural look, comfort, and styling freedom.

2. How to Measure Wig Length for Straight Hair
Measuring straight human hair wigs is simple:
- Place the wig on a mannequin head or lay it flat on a surface.
- Use a measuring tape to measure from the crown (top of the head) straight down to the ends of the hair.
- Make sure the hair is fully straightened and free of waves or tangles.
💡 Tip: For TrendyHair straight wigs, what you see is exactly the measured length — no shrinkage, no visual tricks.

3. How to Measure Wig Length for Wavy and Curly Hair
This is where most people make mistakes. Wavy and curly wigs look shorter than straight ones even when they are the same actual length.
To measure correctly:
- Stretch the hair gently until it’s straight.
- Measure from the crown to the end while the strand is stretched.
- Record that measurement as your wig length.
For example, a 20-inch curly wig might look like a 16-inch wig when it’s not stretched. That’s why TrendyHair Vietnam always provides the stretched length in every product listing — ensuring complete transparency.

4. How Wig Cap Type Affects Measurement
Your wig’s cap construction also impacts how length appears:
- 13×4 or 13×6 Lace Front Wigs: Measure from the front hairline over the top to the end.
- Full Lace Wigs: Measure from the crown straight down the back.
- Closure Wigs: Start from the closure seam, not from the lace edge.
This method ensures consistency no matter the lace type — Transparent Lace or HD Lace — both available in TrendyHair’s collections.
5. How to Choose the Right Wig Length for You
Once you know how to measure wig length correctly, choosing becomes easy. Here’s a quick guide:
- 12–14 inch: Shoulder length – perfect for daily or office looks.
- 16–20 inch: Mid-back – elegant and versatile for any occasion.
- 22–26 inch: Waist length – glamorous, ideal for events or photoshoots.
- 28 inch and above: Statement look – bold, luxurious, and powerful.
At TrendyHair Vietnam, every wig is available in lengths from 8 to 40 inches, made with 100% Vietnamese Raw or Virgin Hair, ensuring durability up to 10 years.
6. Pro Tips to Keep Wig Length Consistent
- Detangle before measuring.
- Always measure dry hair, not wet.
- Never pull too hard; light stretching is enough.
- Compare to your previous wigs for visual accuracy.
- Ask your supplier (like TrendyHair) to confirm the stretched length in videos or photos before ordering.
Conclusion: Measure Smart, Wear Confidently
Knowing how to measure wig length correctly helps you avoid confusion, get accurate results, and choose wigs that perfectly match your style. Remember that curly textures always appear shorter, and measuring from crown to tip while stretched gives the true length.
