This is a straightforward process that will ensure your wig size is right for you.

Wig Size Measurements
There are three wig sizes that you need to know: petite, average and large. These categories are intended to accommodate different head measurements, giving you more flexibility when choosing a wig size suited to you.
We have included an overview of these wig sizes below:
AVERAGE
Our average wig size ranges between 54cm and 57cm (21.25 to 22.5 inches). Around 90% of our customers measure in at an average wig size, so you will find that there are more wigs available if you measure within this size.
PETITE
These wigs are between 51cm and 54cm (20 to 21.25 inches). We currently have over 160 wigs in our petite wig size range so you certainly won’t be missing out! Remember you will have up to an inch of give to adjust at the nape.

How to Measure Head Size for a Wig
Getting your wig measurements doesn’t have to be complicated. Grab a soft tape measure and follow the four simple steps below:
If you are measuring on top of your natural hair, we advise measuring as close as possible to your scalp to ensure you get a more precise measurement.
Petite | Average | Large | |
Circumference | 51-54cm | 54-57cm | 57-60cm |
Front to Nape | 34.5cm | 35.5cm | 38cm |
Ear to Ear Across Forehead | 29cm | 30.5cm | 32cm |
Ear to Ear Over Head | 30.5cm | 32cm | 34cm |
Temple to Temple Around Back | 38cm | 39.5cm | 40.5cm |
Nape to Nape | 12.5cm | 14cm | 15.5cm |
If you love a certain style but don’t know if it is available in your wig size, you can always check the ‘Details’ tab which features on every wig product page on our website. This tab will provide you with detailed product information to check the wig sizes currently available for your favourite wig. It also gives you colour availability and the approximate dimensions of the nape, crown and fringe to make sure you’ve got a wig that fits you in all the right places.
Getting the right wig size is important and we hope you feel more confident with how to measure your wig size as it will make a difference to how comfortable you feel. If you’re worried about your wig being too big and slipping or being so tight that you get a headache, you’re much less likely to wear it – and besides, we want to see you looking and feeling amazing. So let’s get the wig size right and feel as fabulous as we look!

Hi can you give me some advice regarding a wig for hair loss after cancer treatment. I am a black woman with afro hair therefore finding it hard to get anything suitable.i look forward to hearing from you.
Hi Cynthia, to determine the correct cap size, you’ll need to measure the circumference of your head. Here’s a simple way to do it:
Measure the circumference of your head for your size, simply take your cloth tape measure and measure from your front hairline to just above the ears, to where your neck bends and back around to the front hairline.
Average Size: Between 54cm to 57cm (21.25 to 22.5 inches).
Large Size: Larger than 57cm (22.5 to 24 inches).
Petite Size: Between 51cm and 54cm (20 to 21.25 inches).
Once you have your measurement, you can choose the perfect size. If you have any more questions, feel free to ask!
Hello,
I do not have any hair at all due to alopecia. Would I need a customized petite wig cap?
thank you
Why do manufacturers not give a better choice in wig styles for petite size heads. I don’t want a pixie or a long style. I’ve seen a few styles I like but they don’t come in petite or it’s a popular style and I can’t find it.
Petite / average is a little big on me when measured from forehead hairline to nape, in a Jon Renau
do you need to keep your hair cut short for wig to fit right?
I have an odd size head too:
Circumference= 21.5 inches
Ear to ear= 12 inches
Hairline to nape 11 inches
Hairline to chin= 8.25 inches
Would a wig that has a cap ‘that molds itself to fit your head’ be a good choice?
My head measures 57cm would I go up a size or stay regular, I have thinning bobbed hair to tuck in my wig cap, I’m interested in Zara Jon Renau .
Due to the circumference of your head measuring 21.5 inches, this classes you as the bottom side of average.
It would depend on what you would like to order, as the sizes can vary throughout the different wig brands.
Would you like to give us a call or an email with the items you are interested in, we can then advise you further with which size would be most suitable for you?
To whom it may concern,
Thank you for the useful information. From ear to ear, I’m 11/2 in. Circumference 21 1/2 in. But from forehead to the nape of my neck I’m only 11 1/2 in. I guess I have a weird head. lol
Would I order a petite?
Looking forward to your reply.
Never knew wigs came in different sizes. Nobody ever told me and I’ve worn wigs for years. Thanks for the info.
