If you are a first time wig
wearer it is important to remember to try not to decide on a style to
different from your own original hairstyle. A big change in style or
colour could be hard to become accustomed to all at once.
Size
Most Wig shops stock Average
size wigs with the exception of a number of Petite sized wigs. An Average
size wig is designed to fit individuals having a head circumference
of between 21 inches and 22 1/2 inches (52 cm - 57cm) Studies have shown
that regardless of height or weight many people fall within the Average
size range.
How Do I measure My Head Size
Commonly all that you simply should measure is the circumference of your head as the other measurements below are normally proportionate to the circumference, though the other measurements can be valuable in scenarios where your measurements fall outside the standard range.
To measure your head for a
wig, take a cloth or paper tape measure and be sure that it has not
been stretched. In case you're not sure, measure it against a metal
or plastic ruler for accuracy. Then follow the instructions below:

CIRCUMFERENCE: Start
the tape at the middle of your hairline at the forehead. Lay the tape
around to the nape hairline (behind the ears) and around the head where
it will meet back at the front.
EAR TO EAR: Lay the
end of the tape about an inch above the little crease at the top of
your ear between your ear and your head. Then bring the tape across
the top of your head to the other ear at the same point.
FRONT TO BACK: From
the front hairline to the back hairline. For those who have little or
no hair, lay your index, third and ring fingers flat against your forehead
just above your brow bone. At the top of your fingers could be where
a normal hairline would be. Lay the end of the tape at this point and
measure back to about an inch below the little (occipital) bone which
you can feel at the bottom of your skull.
TEMPLE TO TEMPLE: This is where the earpieces of the wig will rest. Begin the tape just in front of your ear, about halfway, just in front of the little cartilage protrusion. Measure the distance across your forehead hairline to the front of the other ear at the very same point.
So What is YOUR SIZE?
As mentioned just before you
definitely only need to use your circumference as a guide. Below is
a simple guide for determining your head size using your Circumference
measurement. However for a more concise breakdown the chart further below
provides a cross references of all three measurements.

| Size | Circumference | Ear to Ear | Front to Back |
| Petite | 21 | 13 | 13 1/4 |
| Average | 21 1/2 | 13 1/2 | 14 1/2 |
| Large | 23 | 14 | 15 1/2 |
You should also try to choose a style that will not have to much
volume of hair around any areas which you do not desire to emphasize.
This will help to balance your specific face shape e.g. Having a shorter
style with hair finishing around the jaw line will help make a longer
face look shorter.
Face Shapes
Oval Face
Clients with an Oval face shape
are fortunate as an oval shape is very versatile and will suit pretty
much any wig style. Long, short, straight or curly styles will all look
fairly natural and flattering.
Round Face
Round face clients really should
search for styles that are just a little longer than their face so as
to avoid emphasizing the rounded nature of their face. Styles with soft
curls and layers will also help to minimize the rounded look of the
face. Short bobs and page boy styles need to be avoided.
Square Face
Clients with a Square face
shape really should avoid styles with sharp lines such as straight cut
fringes. While styles with sweeping fringes and medium length layers that
sit close to the face will reduce the square or angular look.
Heart-Shaped Face
Having a Heart shaped face
clients need to stay away from styles with volume around the crown and
top of the wig. Instead they should search for styles that are a little
fuller around the jaw line that have a soft fringe or no fringe at all.
Oblong Face
Oblong face shapes should search for styles that have a wave or curl around the cheek and/or jaw line. This will give width to your face removing any emphasis of your longer shaped face. Styles which are lengthy and layered will only make your face look longer and really should be avoided.
