How to Choose the Right Watch Size

Measure your wrist

Wrap a soft tape measure (or a strip of paper you then measure) around your wrist just above the wrist bone. Many people fall between about 6 and 7.5 inches (15 to 19 cm).

Lug-to-lug matters most

Lug-to-lug is the distance from the tip of the top lugs to the tip of the bottom lugs. If it's longer than the flat top of your wrist, the watch will overhang and look too big, even if the diameter seems modest. Integrated-bracelet and lugless watches often wear smaller than their diameter suggests.

Rough size guide

Use these as starting points, not rules. Personal style always wins.

• Wrists under 6.5 in (16.5 cm): about 34 to 39 mm diameter, lug-to-lug under 46 mm
• Wrists 6.5 to 7.25 in (16.5 to 18.5 cm): about 38 to 42 mm, lug-to-lug 46 to 50 mm
• Wrists over 7.25 in (18.5 cm): about 41 mm and up

Thickness and comfort

Dress watches are often under 10 mm thick and slide under a cuff. Dive watches and chronographs are typically 12 to 15 mm. A taller watch can feel bigger than its diameter, while a thin one can carry a larger diameter comfortably.

Strap or bracelet choice changes the look too: a tapering bracelet or a softer strap can make a watch feel smaller and more comfortable.
