When investing in a high-quality human hair topper, the most critical decision isn't actually the color or the length—it’s the Base Size. A correctly sized base ensures that the topper covers your thinning areas seamlessly while remaining comfortable, secure, and undetectable all day long.
At ULOFEY, we often hear the question: "How do I actually measure for the right fit?" To help you find your perfect match, we’ve put together this professional, step-by-step guide on how to measure your human hair topper base size.
Step 1: Identify Your Stage of Hair Loss
Before you start measuring, take a moment to look at your hair under good lighting. Hair loss generally falls into three stages:
-
Beginning Stage: Small amount of thinning mainly at the part line.
-
Progressive Stage: The scalp becomes more visible at the crown or top.
-
Advanced Stage: Significant thinning or bald patches across the top of the head.
Step 2: How to Measure (The Practical Steps)
You will need a flexible measuring tape and a mirror.
1. Measure the Width (Side-to-Side)
-
Find the widest points of your thinning area.
-
Place the tape across the top of your head from one side to the other.
-
Expert Advice: Make sure the measurement reaches areas with healthy, strong hair. The clips of your topper need healthy hair to grip onto for a secure fit.
2. Measure the Length (Front-to-Back)
-
Start from your front hairline (or the very beginning of the thinning area).
-
Run the tape over the top of your head to where the thinning ends at the back.
Step 3: The "One-Inch" Golden Rule
This is the most important tip from the ULOFEY specialists:
Add at least 1 inch (2.5 cm) to both your width and length measurements.
-
Why add an inch? You should never clip a hair topper directly onto thinning or fragile hair, as the tension can cause further hair loss (traction alopecia). By adding an inch, you ensure the clips sit securely on your own strong, healthy hair, providing better comfort and protecting your natural follicles.
Step 4: Quick Reference Size Chart
| Base Size (Inches) | Coverage Area | Best For |
| 2" x 4" to 3" x 5" | Small/Parting | Beginning stage; perfect for adding volume to a flat part. |
| 5" x 6" to 6" x 7" | Medium/Crown | Progressive stage; the most popular sizes for top coverage. |
| 8" x 9" or larger | Full Top | Advanced stage; provides maximum coverage and volume. |
Final Tips from ULOFEY
-
Avoid "Oversizing": If your thinning area is small, an oversized base may feel unnecessarily heavy and less breathable. Choose the size that fits your specific needs.
-
Customization Matters: If your measurements fall between sizes, or if you need a specific density to match your extensions, we are here to help you customize the perfect piece.
Conclusion
Knowing how to measure your human hair topper base size is the foundation of a natural, confident look. Once you have your measurements, you are one step closer to your dream hair!
