Lug Width — Misura Ansa

The lug width is the measurement in millimeters between the two lugs of a watch case where the strap is inserted. It's the parameter that determines the compatibility of the strap with a specific watch — a 20mm strap won't fit a watch with 22mm lugs. The most common sizes are 18mm, 20mm, and 22mm for men's watches; 14mm and 16mm for women's or vintage watches. On Milano Straps, you'll find a dedicated landing page for each size, from 16 to 24mm.
