Hats size is usually generally measured in one of three different sizing scales; British, North American or European/Metric.

British hat sizes are given in an imperial measurement of the diameter of the head in inches. Sizes usually range from 6 1/2 to 8. North American hats use the imperial scale however measurements are an eighth of an inch larger than British hats for the same size hat. European hat sizes use the metric sizing standard which is a measure of head circumference given in centimeters. Metric sizes usually range from 52 – 64.

Pachacuti’s range of Panama and Felt hats use the metric or European sizing standard and thus when ordering Panama hats from Pachacuti it is best to give your hat size in centimeters. A conversion chart is given below to convert from British or North American imperial sizes to metric.

Calculating Your Own Hat Size.

To calculate your metric (European) hat size a measurement of the head circumference should be taken in centimeters. This is best achieved by passing a cloth tape measure around the head. Alternatively a piece of string may be used and measured against a ruler or tape measure.

TIPS

It is important that this measurement is taken where a hat would normally rest.

To take a measurement position the tape measure or string so that it rests just above the brow at the front of the head and resting approximately 1 cm about the top of the ears at the side. Pull the tape so that is taut but not too tight and take a measurement.

Hats are sized to the nearest whole centimeter. We advise you size up if your head falls between two measurements.

The way a hat is worn is obviously dependent upon personal taste so this suggestion is only offered as a guide. If you already own a Panama hat then you can measure around the inside of the hat at the point where the crown meets the brim.
