Organic ribbed beanie sizing

A drawing of a hat. The circumference is labeled with "A", the height with "B", the height of the cuff with "C", and the width with "D".

Measure your head circumference with a non-stretchable measuring tape. Place the end of your  tape on your forehead and wrap the rest around the back of your head, keeping it 1″ (2.5 cm) above your ears. Pinch the spot where the tape meets the other end, lift the loop over your head, and note the measurement. Be as careful as possible to get the most precise measurement.
