Size guide

Measure first

It is the one minute that saves nearly every avoidable return. Run a tape measure level, once around the head — about a finger's width above the ears and across the middle of the forehead. Firm, but without pressing in.

Set the tape too high and you lose two centimetres. That is exactly one size.

No tape measure? Use a piece of string and lay it against a ruler afterwards.

The size range

cm	Hat size	S / M / L
53–54 cm	6¾	XS
55–56 cm	6⅞–7	S
57–58 cm	7⅛–7¼	M
59–60 cm	7⅜–7½	L
61–62 cm	7⅝–7¾	XL

The whole size range fits inside about eight centimetres, which is why one centimetre is already a size. With headwear, S, M and L are not sizes in their own right — they are shorthand for centimetres.

Between two sizes? Take the larger. A cap gives very little.

If the size is right and it still does not sit

Then it is the shape, not the circumference. A flat cap adds the least. A newsboy cap has a fuller crown and balances a narrow or long face. A driver cap has a high front and gives you an outline. An ivy cap is the smallest and closest-fitting.

The head circumference is given in centimetres on every cap. The label sewn inside always takes priority over a rule of thumb.
