from the start

Most fit problems trace back to how the measurement was taken, not the number itself.

A soft fabric measuring tape. Metal tapes give inaccurate readings.
With or without a wig cap? If you plan to wear one under your wig, measure with it on. Be consistent either way. Measure your head as you would wear your hair under your wig.
Tape tension: snug, not tight. The tape should sit firmly but not indent your skin. Too loose adds half an inch. Too tight takes one away.
A mirror, or better yet, a friend. A second set of hands gives more accurate readings. If alone, take each measurement twice and average them.

Step 01

Circumference

Place the tape around your head at the hairline, approximately 1/4 inch above your eyebrows and ears. Bring it around the back of your head at the base of your skull. Keep the tape parallel to the floor the entire way around.

Why it mattersCircumference is your largest measurement and sets the overall size of your cap. Getting this right is what makes the rest of the fit work.
Common mistakeTipping the tape up at the back. Keep it level all the way around, if it climbs toward the crown, your reading will be too small.

Step 02

Front to Nape

Start at your hairline at the center of your forehead. Run the tape back over the crown to the nape of your neck, following the curve of your head.

Why it mattersDetermines nape comfort over a full day. If slightly short, you will feel a bunching or pulling at the back of your neck, subtle at first, noticeable by afternoon.
Common mistakeStarting from the center of the scalp instead of the hairline. Always begin at the hairline, and let the tape follow the curve rather than pulling tight.

Step 03

Ear to Ear

From the top of one ear, over the crown, to the top of the other ear.

Why it mattersControls whether the front stays in place. If this measurement is too small for your head, the wig will gradually ride back over the course of the day.
Common mistakeStarting at the earlobe instead of the top curve of the ear. This adds length and can push you into a larger size unnecessarily.

Circumference

Step 01 · Primary measurement

The anchor

Circumference

Place the tape around your head at the hairline — approximately ¼ inch above your eyebrows and ears. Bring it around the back at the base of your skull. Keep the tape parallel to the floor the entire way around.

Why it mattersThis is the primary anchor. When you're between sizes, circumference is always the tiebreaker.
Common mistakeTipping the tape up at the back. Keep it level all the way around.

Front to Nape

Step 02 · Secondary measurement

Nape comfort

Front to Nape

Start at your natural hairline at the center of your forehead. Run the tape back over the crown to the nape of your neck where your hairline ends. Let the tape follow the curve of your head.

Why it mattersDetermines nape comfort over a full day. If slightly short, you'll feel it by afternoon.
Common mistakeStarting from the scalp instead of the hairline. Always begin at the hairline.

Ear to Ear

Step 03 · Secondary measurement

Front stability

Ear to Ear

Begin at the top of one ear where it starts to curve. Bring the tape up and over the crown to the same point on the opposite ear. The tape runs across the top of your head, not around it.

Why it mattersControls whether the front stays in place. If too small, the wig will gradually ride back over the course of the day.

Understanding your size

Your cap has a range

The adjustable back strap gives you roughly half an inch of flexibility in each direction.
If you're between sizes, sizing up always works — a slightly larger cap adjusted with the strap fits better than a slightly small one.
A full day of wear tells you more than 10 minutes. Nape comfort reveals itself over hours.

On comfort and security

A well-fitting wig should feel comfortable — not tight, not grippy.

"Comfortable is correct.
Tight is not security."
