A:Answer We appreciate you coming to us with your question. We aspire to provide exceptional service to our customers. Samsung watch bands come in two sizes. The S/M size fits wrists measuring 130mm to 190mm, while the M/L size fits wrists measuring 145mm to 205mm. To determine the right size for you, measure your wrist using a cloth or paper tape measure. If you don't have one, you can use a string. Simply take a piece of string or rope, wrap it around your wrist, mark the spot where it meets, and then measure the length using a ruler or tape measure in millimeters. Samsung watches come in various shapes and sizes, but many of them use the same bandwidth. As long as you have the correct width, you can switch bands as you like. If you're looking for a new look, we offer a wide selection of replacement bands on our website and online. If you have any other questions, contact us at Support. -Kelvin
