Calculating Your Cap Or Hat Size
Choosing a cap of the correct size is important to your enjoyment of your complete traditional school uniform. Heads come in all shapes and sizes and there is no such thing as an average cap size so it is important that clients are confident that they are ordering a cap that will fit them well. The available sizes for our different caps (and hats) are clearly indicated on the individual items pages.

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

British cap & hat sizes are given in an imperial measurement and the sizes usually range from 6 1/2 to 8. North America use the imperial scale however measurements are an eighth of an inch larger than British caps for the same size cap. European cap sizes use the metric sizing standard which is a measure of head circumference given in centimeters. Metric sizes usually range from 52 - 64.

Adult Size School Uniform range of school caps use the British imperial sizing standard and when ordering a cap you will need to enter you cap size in this standard. You can do this via the drop down menus.

A conversion chart is given below to convert from North American or European metric to British imperial sizes.

British (inch) ----------- U.S. (inch) --------------- European (cm)
6 5/8 ----------------------- 6 3/4 ------------------------ 54
6 3/4 ----------------------- 6 7/8 ------------------------ 55
6 7/8 ----------------------- 7 ------------------------------ 56
7 ---------------------------- 7 1/8 ------------------------- 57
7 1/8 ---------------------- 7 1/4 ------------------------- 58
7 1/4 ---------------------- 7 3/8 ------------------------- 59
7 3/8 ---------------------- 7 1/2 ------------------------- 60
7 1/2 ---------------------- 7 5/8 ------------------------- 61
7 5/8 ---------------------- 8 3/4 ------------------------- 62
7 3/4 ---------------------- 7 7/8 ------------------------- 63
7 7/8 ---------------------- 8 ------------------------------- 64

To calculate your metric cap 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. It is important that this measurement is taken where the base of the cap 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, touching the top of the ears at the side. Pull the tape so that is taught but not too tight and take a measurement.

Take the measurement in centimetres and convert it to British imperial using the chart given above.

Needless to say that the same procedure also applies when sizing a girls hat or boys or girls boater.
