Apple finally revealed new information on the Apple Watch on Monday, including when it will be available, how much it will cost and more. If you’re interested in pre-ordering on April 10, you might also want to know what size you should be considering. Thankfully, Apple has a sizing guide for that, which walks us through the different case sizes and the band sizes of each model.
You’ll find that the 38mm case measures 38.6mm x 33.3mm x 10.5mm and the 42mm case measures 42mm x 35.9mm x 10.5mm. That’s the bulk of the Apple Watch, the part that sits on your wrists. Folks with smaller, more petite wrists may gravitate toward the 38mm case, while the larger version may be reserved for the bulkier humans who walk among us.
Band sizes differ depending on the buckle and case combination. The modern buckle available for the 38mm case fits small, medium and large wrists with 135mm – 150mm wrist circumferences, 145mm to 165mm wrist circumferences and 160 to 180mm wrist circumferences, respectively. The leather loop will be available for the 42mm case for medium and large size wrists. The milanese loop, link bracelet and classic buckle fit all wrist sizes. Finally, Apple will sell small/medium and medium/large sport band options for both the 38mm and 42mm sport band cases.
