Applehas kept this simple, fortunately, and there are only two options. A medium band size that fits 150-185mm wrists and a large band size that fits 180-210mm
Ithink using this formula, that an acceptable ratio falls between 4.0 and 5.0. Anything below 4.0 is too big and anything above 5 is too small. Here is an example using a 44mm watch which should be too big for some with38mm is 1.49 inches; 40 mm is 1.57 inches; So, what size does apple watch band 44mm come in? The answer is both yes and no. Apple Watch Band 44mm will fit a 42mm watch, but not all bands are interchangeable. When it comes to Apple Watch bands, you have the option to choose between two sizes- 38/40/41mm or 42/44/45mm. s3j214.
