The Perfect Fit

How to Measure

We recommend that all our customers have their head size professionally measured in our London shop or take this measurement themselves at home. Please do not simply order your Herbert Johnson hat in the size you may be accustomed to wearing for other brands, as we cannot guarantee the accuracy of other brands hat sizes. Please ensure you order the correct size by following the instructions below.

Simply place a string or flexible measuring tape around your head just above your ear by 1cm and across the mid-forehead, completely circling your head. Hold the tape firmly, but not too tightly, approx 1cm above your ear.

Measure your head exactly where you want the hat to sit on your head. Always measure in centimetres as converting between different measuring systems can often cause inaccuracies.

If your measurement in cm’s falls between sizes, round up to the nearest half centimetre. It is advisable to repeat this process to ensure your measuring technique is yielding accurate results. It may help to do this in front of the mirror or have a friend to help for accuracy.

To get the perfect fit, we suggest ordering your hat in the nearest half size up and then send your order reference number with your exact head measurement to 2 decimal places to enquiries-hj@herbert-johnson.co.uk and we will craft your hat to fit.  If you are in any way unsure of which size you should order, please contact us via the above email address for advice.

Please note our core range of standard hat styles is only available in whole sizes 56cm - 61cm. Please order the best available size from our website or contact our team to be added to our waiting list for other styles/sizes/felt options when available.
