Hats size is usually measured in one of three different sizing scales:

1. British hat sizes are an imperial measurement of the diameter of the head in inches (sizes usually range from 6 1/2 to 8)
2. North American hats use imperial measurements but are an eighth of an inch larger than British hats for the same sized hat
3. European/metric hat sizes use the metric sizing standard – a measure of head circumference in centimetres (metric sizes usually range from 52 – 64)

Our range of Panama and felt hats use the European/metric sizing standard. Thus when ordering Panama hats from Pachacuti it is best to give your hat size in centimetres. Please see the conversion chart below to convert from British or North American imperial sizes to metric.

Calculating Your Own Hat Size.

To calculate your European/metric hat size, measure the circumference of your head in centimetres. The best way to do this is to pass a metric tape measure around your head. Alternatively, you can use a piece of string may which you can measure against a ruler or tape measure.

TIPS

It is important that you take this measurement where a hat would normally sit.

Firstly, position the tape measure or string so that it rests just above the brow at the front of the head, and approximately 1 cm above the top of the ears on each side. Then pull the tape so that is taut but not too tight. Finally, take the measurement.

Hats sizes are measured to the nearest whole centimetre. We therefore advise you to size up to the next centimetre if your head measurement is between whole centimetres.

The way a person wears their hat depends on personal taste, so this suggestion is for guidance purposes only. If you already own a Panama hat, measure around the inside of the hat at the point where the crown meets the brim.
