Samsung Watch Strap Sizes
Lug width and strap fitting for every Samsung model in our index. Tap a watch for the full guide.
Across the 5 Samsung models with standard lugs in our index, lug widths are 20mm (4), 22mm (1). The most common is 20mm, but don't assume: sizes vary within the brand, so check your exact model below. the Galaxy Watch Ultra and the Galaxy Watch 8 / 8 Classic use an integrated or proprietary fitting, so normal straps need an adapter (how that works). For a model-by-model explanation, see our Galaxy Watch band size guide.
