Although an Apple Watch band can be adjusted, the case size must be determined before buying. We’ve put together this Apple Watch size guide to help you choose the best option.
The Apple Watch’s first three iterations, including Series 3 (which you can still buy), are available in 38mm and 42mm sizes.
Are you unsure about which Apple Watch version is right for you? Let’s go through how to estimate your wrist and what the four models have in common.
Measuring Your Wrist for an Apple Watch
Although the fit of your watch is a personal preference, it’s crucial to know how big your wrist is before you purchase an Apple Watch or an alternative band.
But, how can you be certain? Simply take out a flexible measuring tape and measure the size of your wrist.
Wrap the tape around your wrist, just below where your wrist bone falls and about where you’d typically wear the band, and line it up with the dimensions of your Watch model.
A small wrist measures 5 to 6.5 inches, while a big wrist measures 7 to 8.5 inches. The good news is that many Apple Watch bands can be adjusted using velcro or through the holes of sports straps to get a very particular fit.
Just be careful not to go too tight or too loose; not only will it be unpleasant, but it will also compromise the Apple Watch’s heart rate monitor‘s accuracy.
Sizes of Apple Watches
38mm, 42mm, and 40mm and 44mm.
Apple Watch Series 4 up to the Series 6 are available in 40mm and 44mm casings, however previous versions (Series 3 and lower) are still available in 38mm and 42mm casings.
Although the straps always play a part in the precise fit of the device on your wrist, these measures represent the size of the bezel. In addition, unlike most other manufacturers, Apple measures its Watch vertically rather than horizontally.
Assume a width of 34mm, a depth of 10.7mm, and a case weight of roughly 30g for the 40mm variant. You’ll have to cope with a 38mm case width, the same 10.7mm depth, and a 36g case weight for the larger 44m variant.
The width of the 38mm variant is 33.3mm, while the 44mm variant is 35.9mm wide. Like the Series 4, there’s really no difference in depth between the two devices, with each measuring 10.5mm.
These sizes are vital for determining which face will be most suited to your wrist, so cutting out a paper equivalent to assess on your wrist – or just going to an Apple shop and trying on all four sizes – isn’t a bad idea.
The significance of selecting the appropriate band
The material and tightness of the band, of course, have a greater impact on comfort.
Apple offers a detailed reference on each of its band types (Classic Buckle, Modern Buckle, Link Bracelet and Sport, Milanese Loop), some of which need you to select a size when purchasing, and others (like the Sport bands) that come with both a S/M and M/L strap to choose from.
Also, keep in mind that any bands that work with Series 1-3 will correlate to the Series 4 or Series 5‘s larger/smaller size. As a result, a Series 2 band in 38mm will fit the Series 5 in 40mm.
You may also look through a variety of third-party Apple Watch bands. They’re virtually always less expensive, and many of them look identical to Apple’s own models.
