Head Measurements

Cancer Headwear is "one size fits most", being adjustable in most cases with elastic at the back of the neck and additional ties, or made from stretch cotton or bamboo fabric.  If you do have concerns, however, please advise the size of your head (measured around the head, just above the ears and from above the eyebrows to the nape of the neck), and usually we can custom-make a size to fit.
Hat Show Handmade Hats are made to fit a 22inch (56cms) head, which is average size, unless stipulated in the item description.  I will make custom sizes on request, whenever possible.  
For other men's hats and ladies' fashion hats, stick-on re-sizers that can be placed inside the headband of the hat are available from the website.
