Watch Strap Size Calculator

This calculator provides a starting recommendation from three inputs: measured lug width, wrist circumference and watch type. Measure the clear distance between the inside faces of the lugs in millimetres. Enter wrist circumference without adding extra length for a buckle or clasp.

What the result means

The recommended strap width follows the lug-width input. Length is grouped into short, regular and long ranges so the result is easy to compare with a product listing. Dress, field, diver and sport are recorded as the watch type for the result and do not override a measured lug width.

The result is a guide, not a guarantee of fit. Curved lugs, large keepers, spring-bar clearance and personal wearing preference can change the best choice. Check the product record before ordering and ask DailyTime Store when a required dimension is UNKNOWN.
