When you're shopping for a wig, it is easy to focus on the fun parts: the length, texture, color and style. But there is another detail that deserves just as much attention — how the wig actually fits your head.
A wig that is too tight can feel uncomfortable after a few hours. One that is too loose may shift or require more adjustment than you want. Taking your measurements before ordering gives you better information when selecting a cap size.
Before You Start Measuring
Grab a flexible cloth measuring tape, something to write your measurements down with, and a mirror. If possible, having someone help you can make some of the measurements easier.
Your hair should also be prepared as close as possible to the way you plan to wear it underneath your wig. If you normally braid your hair down before installing a wig, for example, measuring over a large bun or bulky hairstyle may give you a different result.
The 6 Head Measurements to Take
Head Circumference
Start at the center of your front hairline. Bring the measuring tape around your head, passing just above your ears and around the back of your head before returning to the starting point.
Circumference is one of the measurements most commonly associated with wig cap sizing, but it shouldn't necessarily be the only measurement you consider.
Front Hairline to Nape
Place the beginning of the measuring tape at the center of your front hairline. Run it straight over the top of your head and down to the nape of your neck.
This tells you how much room you need from the front of the wig cap to the back.
Ear to Ear Across the Forehead
Start near the hairline at one ear. Bring the tape across your forehead along the hairline until you reach the same point near the opposite ear.
Keep the tape positioned where you would naturally expect the front of your wig to sit.
Ear to Ear Over the Top of Your Head
Start above one ear and bring the tape across the crown of your head to the same position above the opposite ear.
This measurement helps account for the width and shape of the top of your head.
Temple to Temple Around the Back
Begin at one temple. Bring the measuring tape around the back of your head and stop at the opposite temple.
Make sure the tape follows the natural curve of your head rather than lifting away from it.
Nape of the Neck
Measure horizontally across the lower hairline at the nape of your neck. Start where the hairline begins behind one ear and measure across to the corresponding point on the other side.
Although this is a smaller measurement, it can still matter when you're trying to achieve a secure and comfortable fit.
Write Every Measurement Down
Don't rely on memory. Write each number down as you take it, and label it clearly. If a measurement seems unusual, take it again.
In fact, measuring twice is a good habit even when the first number looks right. A small difference in where the tape sits can change your result.
Don't Choose a Wig Size From Circumference Alone
Two people can have a similar circumference and still have different head shapes. One person may need more room from front to nape, while another may need more room across the crown.
That's why taking all six measurements gives you a better picture than relying on a single number.
When shopping for a wig, compare your measurements with the sizing information provided for that particular wig. If your measurements don't all fall neatly into one size category, look at the complete fit rather than automatically choosing based on one measurement.
What About Adjustable Wig Caps?
Adjustable straps and other cap features can help fine-tune the fit, but they aren't a substitute for starting with an appropriate cap size. An adjustment feature can help secure a wig that is already reasonably close to your measurements; it cannot completely correct a cap that is dramatically too small or too large.
Why Wig Fit Matters for Your Edges, Too
Fit isn't only about whether the wig stays in place. You also want to pay attention to how the wig feels around your hairline.
If you're constantly tightening, pulling or repositioning your wig, that's a sign to look at the fit and installation method. Your wig should feel secure without requiring unnecessary tension around your edges.

Measure Before You Shop
Measuring your head isn't the most exciting part of buying a new wig, but it can save you frustration later. It only takes a few minutes, and once you have your measurements written down, you can keep them for future wig purchases.
Just remember that your measurements can change if your natural hair becomes significantly longer, thicker, or is prepared differently underneath the wig. If it has been a while since you measured, it doesn't hurt to check again.

What should I use to measure my head for a wig?
A flexible cloth measuring tape is the easiest option because it can follow the curves of your head. A rigid ruler isn't suitable for measuring around the head accurately.
Should I measure my head with my hair braided?
Ideally, prepare your natural hair as close as possible to the way you expect to wear it underneath your wig. If you usually wear a braid-down, measuring with your hair similarly flattened can give you a more useful result than measuring over a bulky hairstyle.
How tight should the measuring tape be?
Keep it flat and snug without squeezing your scalp. You don't want extra slack, but you also don't want to pull the tape unnaturally tight.
What if my measurements fall between wig sizes?
Look at all of your measurements and the sizing information for the particular wig you're considering. Circumference is important, but head shape and the other measurements can affect how a cap fits.
