Want to know how to measure your head for a wig? We’ve got all the tips, tricks, and steps you need to make sure you find the perfect fit for your new wig.


It’s not a tricky or complicated process, but it’s super important to get it right.


A wig that’s too big can slip around and feel uncomfortable, while a wig that’s too small can cause headaches and discomfort. Not to mention, a properly fitted wig will look and feel more natural.


Scroll down for our step-by-step guide on how to measure your head for a wig and find your perfect wig cap size.

How to Measure Your Head for a Wig Properly

Measuring your head for a wig needs to be done properly to ensure a snug but comfortable fit for your head. We've broken down the process into step-by-step instructions to help you get your measurements right.


We'd recommend taking two sets of measurements to get the most accurate results, especially when buying wigs online.

Step One: Take the Circumference

Stand in front of a mirror with a flexible measuring tape.


Start at the centre of your forehead above your eyebrows. Wrap the tape around your head, over your ears, and back to your forehead, keeping it level and snug.


Note the measurement in inches or centimetres. This helps you find the right wig cap size. A friend’s help can make it even easier and more accurate!

Step Two: Measure Front to Nape

Hold the flexible measuring tape and place one end at the centre of your forehead where your natural hairline begins. Gently pull the tape over the top of your head and down to the nape of your neck.


Make sure the tape lays flat against your scalp for an accurate reading. This front-to-nape measurement is essential for finding a comfortable and well-fitting wig cap.

Step Three: Go Ear to Ear Across Your Forehead

Using your flexible measuring tape, start by placing one end at the top of your ear.


Gently stretch the tape across your forehead to the top of your other ear, making sure it follows a straight path just above your eyebrows.


This "ear to ear across forehead" measurement ensures your wig cap fits perfectly across your forehead and temples.

Step Four: Go Ear to Ear Over Your Head

Start by placing one end of the tape at the top of one ear and gently pull it across the crown of your head to the top of the other ear. 


Make sure the tape lays flat and follows a straight path over the highest point of your head.


This step is key to ensuring your wig cap fits securely and comfortably across the crown of your head, giving your natural hair room to breathe.

Step Five: Measure Temple to Temple Around the Back

For an accurate temple-to-temple measurement, place one end of the tape at your temple, near the natural hairline.


Gently pull it around the back of your head, just above the nape, to the opposite temple. Keep the tape flat against your scalp for a precise reading.


This helps ensure your wig cap blends with your natural hairline perfectly and provides a snug, comfortable fit.

Step Six: Measure the Nape of Your Neck

To measure the nape of your neck, place one end of the measuring tape at the base of your ear on one side.


Then, gently pull the tape across the back of your neck to the base of your other ear. Ensure the tape is snug but not too tight for an accurate measurement and a comfortable fit.

RiRi’s Top Tip: Measuring your head on your own is certainly doable, but having a friend assist you can make the process smoother and more precise. 


With an extra set of hands, you can ensure the measuring tape stays level and snug, reducing the chances of any miscalculations. A friend can help read the tape more easily and adjust its position as needed, ensuring that every measurement is as accurate as possible.

How to Adjust a "One Size" Wig to Your Perfect Wig Size

Wigs labelled as "one size" might not fit everyone perfectly right out of the box, but don't worry! Many wigs come with adjustable features, allowing you to fine-tune the fit for maximum comfort and security.


Wondering how to make your wig larger or smaller? Here's a simple guide to help you match your wig to your own measurements.

Making a Wig Smaller:

Tip Description
Tighten the Adjustable Straps Pull straps tighter, adjusting hooks or Velcro tabs. Try on the wig for proper fit, adjusting incrementally for a snug but comfortable fit.
Use Wig Clips (if straps aren't enough) Sew wig clips inside the cap. Fasten clips to your natural hair for additional security.

Making a Wig Larger:

Tip Description
Release the Adjustable Straps Loosen the straps by moving the hooks or Velcro tabs to a looser setting. This increases the cap's circumference.
Stretch the Cap (for some wigs) Place the wig on a slightly larger wig stand or mannequin head for a day or two to gently stretch the cap.
Add Elastic Bands Sew in elastic bands around the edge of the wig cap for additional customisation and size increase.

Ensuring a proper fit for your "one size" wig can make a big difference in comfort and natural appearance.


It's important to take your time and make small adjustments to get it just right. Be patient, and you'll enjoy a wig that seamlessly complements your unique style.

FAQs

How Do I Know If a Wig Will Fit Me?

A wig will fit you if its cap size matches your head measurements. Key areas to measure include the circumference, front to nape, ear to ear, and nape of the neck. Use these measurements to compare with the wig's size chart for an accurate fit.

How Should a Wig Fit on Your Head?

A wig should fit snugly on your head without causing discomfort. It should sit securely, covering your natural hairline and aligning with your measurements. The wig shouldn't shift or move during daily activities, ensuring it stays in place and looks natural all day long.

What is the 4 Finger Rule for Wigs?

The 4 Finger Rule helps position your wig correctly. Place four fingers horizontally above your eyebrows to find where the wig’s hairline should start. This ensures your wig sits naturally, mimicking the placement of your natural hairline for a more realistic look.

Do Wigs Fit Everyone?

Yes, wigs can fit everyone with the right adjustments. It's essential to measure your head accurately and choose the appropriate wig size. Many wigs also come with adjustable straps and customisable features to ensure a comfortable and secure fit for all head sizes and shapes.
