Women's hat sizes are fairly intuitive. The average women's head size measures around 57cm. If you are unsure of your hat size the Gigi Pip small/medium hat would be the best starting point. The small/medium hat size is made to fit 57cm + can be adjusted down to 55cm. If you know you have a slightly larger head go with the 59cm size. As far as Gigi Pip sizing goes this is a medium/large, made to fit a 59cm head size + then can be adjusted down to 57cm. The largest size Gigi Pip offers is a 61 cm, labeled as an XL, like our other sizes the 61 can be sized down to 59 cm. For women who feel they have a slightly smaller head than normal we recommend an XS which begins at 55cm + can be sized down to 53 cm. In select styles we offer kids sizing which begins at 53 cm + can be adjusted to 51 cm.
XS (53cm to 55cm)
S/M (55cm to 57cm)
M/L (57cm to 59cm)
XL (59cm to 61cm)

There are two primary methods of measuring your hat size + are based on the style in which you wear your hat. You will need to take both measurements (shown below) + then use the larger of the two measurements to determine your hat size. Once you've received your hat, you can decide how you would like to wear it + adjust your hat size accordingly.
TIP: If you don't have a textile measuring tape, use a string or piece of yarn to measure the distance around your head. After you have marked the yarn around your head, lay it out flat on the ground or table + measure the straightened out piece of yarn with a measuring stick or regular measuring tape.


- Use a textile measuring tape (or string) to measure the distance around your head crossing through the center part of the back of your head + the forehead just above the eyebrow. The tape should be level with the ground.
- Check the measurement of the tape wrapped around your head. Hat sizing is in cm. If you are in-between sizes, we suggest sizing up + adjusting your hat accordingly.


- Use a textile measuring tape to measure the distance around your head passing through the back of your head, just above the neck, + the front of your head high on the brow. The tape should be higher in front than in back.
- Check the measurement of the tape wrapped around your head. Wearing a hat Halo style is usually a smaller hat size than wearing a hat traditionally. Since there is typically a difference in measurement we recommend using the larger of the two hat sizes. If you are in-between sizes, we suggest sizing up and adjusting down.
Remember, if you still feel unsure on which hat size to go with, we recommend the 57 cm- a small/medium.
