How to measure your hat size.
Every Lock & Co. hat purchased is carefully and expertly hand-prepared in our London shop by one of our Hatters, before being whisked out of our famous green front door.
To find your perfect hat size, we suggest booking a virtual appointment for a consultation with one of our hatters here.
At Lock & Co., we sell the finest hats and caps. To achieve this, we pay particular attention to specific hat characteristics - style, fit, durability, and materials. We share these characteristics with you for each hat to help you decide on the perfect choice.
Place a tape measure around your head positioned mid-forehead and just above the ears.
