Choosing the right wig starts with one key step: getting the correct head measurement. A well-fitted wig looks more natural, feels more comfortable, and stays secure throughout the day. Whether you're shopping for your first wig or upgrading your collection, learning how to measure your head properly will help you avoid common sizing issues and find your perfect fit.

Why Wig Size Matters?

Wearing the wrong wig size can lead to slipping, tightness, headaches, or an unnatural look. A wig that fits correctly sits comfortably along your hairline, blends better with your natural features, and feels effortless to wear. Since not all head sizes are the same, taking a few minutes to measure can make a big difference in how confident you feel in your wig.

What You'll Need Before Measuring

Before you begin, make sure you have the following:

  • A soft measuring tape (cloth or flexible plastic works best)
  • A mirror to help guide placement
  • Your hair is styled the way you plan to wear it under the wig

If you don't have a measuring tape, you can use a piece of string and measure it later with a ruler.

How to Measure Your Head for a Wig?

There are three main measurements you'll need to determine your wig size. For the most accurate results, keep the tape snug but not tight.

1. Head Circumference

Place the measuring tape at the center of your forehead, just above your eyebrows. Wrap it around your head, following your natural hairline, behind your ears, and around the nape of your neck. Bring the tape back to the starting point and note the measurement.

2. Front to Nape

Start at the center of your hairline on your forehead. Run the tape straight over the top of your head to the nape of your neck. This measurement helps determine how well the wig will sit from front to back.

3. Ear to Ear (Across the Top)

Place the tape at the top of one ear, run it across the crown of your head, and bring it down to the top of the other ear. This measurement helps ensure the wig fits comfortably from side to side.

Understanding Wig Size Categories

Once you have your measurements, you can compare them to standard wig size charts. Most wigs fall into these general categories:

  • Small: Approximately 21 - 21.5 inches
  • Medium: Approximately 22 - 22.5 inches
  • Large: Approximately 23 - 23.5 inches

Medium is the most common wig size and fits the majority of people. Many wigs also include adjustable straps or elastic bands, allowing you to customize the fit for extra comfort.

Tips for Getting the Best Fit

For the most accurate results, measure your head more than once and take the average. If your measurements fall between two sizes, choosing the larger size is usually more comfortable, especially if the wig includes adjustable features.

Also, consider how you'll wear your hair underneath. Braids, twists, or thicker natural hair can slightly affect the fit, so measure with your intended base style in mind.

What If the Wig Doesn't Fit Perfectly?

If your wig feels slightly loose or tight, don't worry. UNice wigs can be adjusted using built-in drawstrings or elastic bands. Wig grips and caps can also help improve comfort and security without altering the wig itself.
