The 45mm Apple Watch Series 7 has a wrist size of between 140mm and 220mm, or approximately 5.5 inches to 8.5 inches. The 45mm model also has an extra-large strap option; that strap is for wrists between 160mm and 245mm, or about 6 inches to almost 10 inches. If your Apple Watch is 38mm or 40mm, buy a 41mm band. If your Apple Watch is 42mm or 44mm, buy a 45mm band.
Smaller sizes and larger sizes are grouped together in terms of compatibility, although this advice does not apply to Apple Watch Series 2 or earlier. Of course, as always, you'll need the right strap size for the right watch size. Older bands that fit the 40mm Apple Watch Series 6 will fit Series 7, and the 44mm straps will fit the new 45mm size. Remember that since all bands will be compatible with the new Apple Watch, there is no reason to wait for the launch of Apple Watch Series 7 to buy new bands if you are looking for a new look.

Made of leather, the modern buckle is the only Apple band that is exclusive to the smaller Apple Watch models of 40 and 41 mm.

Whether you're buying new bands for your current Apple Watch or want to know what will happen to your current bands when you buy a new Apple Watch, you'll need to do some research. Usually, any watch band will be compatible with any Apple Watch, however, there are some differences in which Apple Watch band you can use depending on whether you have opted for the large or small version of your Apple Watch generation. Not all Apple Watch bands are available in all sizes and not all are compatible with both models. Apple Watch band sizes match the size of each device to ensure a comfortable fit and proper use.
However, if you use third-party Apple Watch bands, the band may wear out over time. Luckily, Apple has stated that all of the above bands will work with the Apple Watch Series 7, so you don't need to replace all of your best Apple Watch bands if you plan to buy the newest Apple Watch. These lengths can be added to the size of the Apple Watch to approximately equal the circumference of the wrist, plus or minus a few millimeters.
