When it comes to measuring your head, the best tool for the job is a flexible measuring tape used by tailors and seamstresses. This type of measuring tape is usually made of soft vinyl and will not stretch. If you don't have access to a tailor’s measuring tape, you can use a piece of string or ribbon. Just make sure whatever you use doesn’t stretch, or you may not get an accurate measurement.
Tip: Whether you measure the circumference of your head in inches or centimeters is up to you. However, centimeters are easier for getting an accurate measurement, since the units are smaller.
Start by wrapping the tape or string around the circumference of your head at the same location you would normally wear a hat — usually about an inch above the eyebrows and just above the ears. Hold the leading edge of the tape against your forehead with one hand. Use your other hand to bring the rest of the tape around your head until it overlaps the leading edge. Pull the tape snug and, with two fingers, pinch it just beneath the overlap point. Hold it firmly so that your forefinger marks the overlap point. Remove the tape and note the length on a piece of paper.
You may want to measure two or three times to ensure you get an accurate measurement. If you’re having difficulty measuring your head size by yourself, ask a family member or friend to assist you. If you’re using string, the process is the same, except you will need a traditional measuring tape or ruler to measure the length of the string. Finally, refer to the chart above to find your ideal hat size.*
