The sports band is an adjustable strap made of fluoroelastomer and comes in two sizes to fit smaller and larger Apple Watch models. Because this band has holes for an adjustable fit, you just need to make sure that the size range below matches your wrist size. For the most part, each Apple Watch band has a good size range, and you just need to pay close attention to whether your wrist is smaller than average or larger than average. According to Apple, watch bands for 38mm, 40mm and 41mm cases are compatible with cases of all three sizes.
The watch straps for 42 mm, 44 mm and 44 mm cases, on the other hand, are compatible with cases of all three sizes. Note that the average female wrist measures between 140mm or 5.5 inches and 170mm or 6.7 inches. The average male wrist measures between 165 mm or 6.5 inches and 195 mm or 7.8 inches. The 38mm Apple Watch model can use bands up to 22mm wide and up to 24mm wide for the 42mm Apple Watch.
That means that an Apple Watch band that fits a 38mm Apple Watch Series 3 will also fit the 40mm Apple Watch Series 6.available in select pre-configured strap and case combinations. Keep in mind that larger Apple Watches have longer strap options, and smaller watches offer shorter strap options. The Simple Tour Made in France leather strap, for example, is smaller in white than in gold, some colors are preferred for women and others for men. 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.
Apple has conveniently aligned band and face sizes, making the task of choosing a band somewhat easier. Buying the Apple Watch band from the Apple website is a great way to ensure the best quality. The product detail pages for all other bands also specify the wrist circumferences they are designed for when worn together with the Apple Watch. If you plan to buy the 40mm Apple Watch model, you can expect it to have a width of 34mm, a depth of 10.7mm, and a case weight of around 30g.
For those who don't have a cloth tape measure, you can take a piece of string and wrap it around your wrist, using a standard flat measuring tape or a ruler to measure the part of the rope that fits around your wrist like a watch would. With either strap, it's a good idea to go to an Apple retail store if you can to try on and get an idea of the different materials and how they feel on your wrist. If you're preparing to buy an Apple Watch, you should consider the wrist size and strap options available to get the best fit.
