Apple Watch Model Sizes

The following is Apple Watch size guide, showing the Apple Watch band measurements by watch model:

• Apple Watch Series 1: 38 mm and 42 mm
• Apple Watch Series 2: 38 mm and 42 mm
• Apple Watch Series 3: 38 mm and 42 mm
• Apple Watch Series 4: 40 mm and 44 mm
• Apple Watch Series 5: 40 mm and 44 mm
• Apple Watch Series 6: 40 mm and 44 mm
• Apple Watch Series 7: 41 mm and 45 mm

What is the difference between 40 and 44 mm Apple Watches? This refers to the size of the height of the Apple Watch display. Keep in mind that larger Apple Watches have longer band options, and smaller watches will offer shorter band options. The Sport Loop band for the 40 mm watch can fit 130–200 mm wrists, while the band for the 44 mm watch can fit 140–220 mm wrists. You can get the perfect fit if you just follow this Apple Watch band size guide!

Quick Metric vs. Imperial Conversions for Apple Watch Sizing

These can come in handy when measuring your wrist circumference in order to calculate your Apple Watch band size.

Apple Watch Sizes

Apple Watch sizes refer to the length from the top of the device to the bottom, not from one side to the other.

• 38 mm is 1.49 inches
• 40 mm is 1.57 inches
• 42 mm is 1.65 inches
• 44 mm is 1.73 inches

Apple Watch Band Lengths

These lengths can be added to the Apple Watch size to approximately equal the circumference of your wrist, give or take a few millimeters. We recommend using Apple’s watch band size chart for the best fit, but these measurements can still come in handy!

• 130 mm is 5.12 inches
• 140 mm is 5.51 inches
• 200 mm is 7.87 inches
• 220 mm is 8.66 inches

If you are looking for a kid size Apple Watch band, the 130 mm may be your best option. You can also shop third-party watch bands specifically made for children with smaller wrists!

Step 1: Which Apple Watch Do I Have?

Remember: Apple Watch size is the size of the device itself, without the band. Apple Watch band sizes coordinate with the size of each device to ensure a comfortable fit and proper wear. When buying a new Apple Watch band, it’s crucial to choose one that fits the size of your watch. Luckily, the same band will fit every Apple Watch model as long as it’s the same device size. 

The quickest way to find out which Apple Watch size you have is to remove the watch from your wrist and look at the engraving on the back.

You can also check the model in the settings on your iPhone. If you’d like to know more about the different Apple Watch models and their many distinguishing features, we can help with that. If you are shopping around for a new model, check out which Apple Watch you should buy in 2021!

Step 2: Which Band Fits My Apple Watch?

The smaller Apple Watch will be either 38 mm or 40 mm, depending on the model. The larger Apple Watch will be either 42 mm or 44 mm, depending on the model. The 2  mm difference is in the display rather than the watch. That means that an Apple Watch band that fits a 38 mm Series 3 Apple Watch will also fit the 40 mm Series 6 Apple Watch. Likewise, a band that fits a 44 mm Series 5 will fit a 42 mm Series 2.

Step 3: How to Measure Wrist Size for an Apple Watch Band

Now that you understand how to measure Apple Watch band size, you need to learn how to measure wrist size! The safest thing to do for best results is to the Apple Watch band size chart. This official guide lets you cut out a paper band to help you get the perfect fit, and it really works!

It can be easy to simply estimate Apple Watch band sizes when it comes to the Sport Band and Sport Loop because the options are S/M for shorter bands or M/L for longer bands, and they’re adjustable. However, not all bands are! The Solo Loop, for example, does have some stretch to it, but it’s not possible to adjust it. 

If you don’t have a printer and you want to measure your wrist in a pinch, cut a strip of paper or a string. Use a pen to mark the size of your wrist on the paper or string, then measure it with a ruler. You can then input the measurements on Apple’s website by clicking the Start your measurement button to get the correct size.

Pro Tip: Even if you aren’t going to buy your band on Apple’s website, you can use their sizing tools to figure out what size to get! Just pretend you’re shopping for an Apple Watch and follow the steps.

Using a Hand Measurement App

If you don’t have a printer or a ruler, you can always use a hand measurement app to help you measure your wrist. Keep in mind that this is not the most accurate measurement and may result in an ill-fitting band.

1. Open the Measure app (It’s a free stock app that comes with your iPhone).
2. Follow the on-screen directions until the white semicircles appear in bold, indicating that you are ready to measure.
3. Position the spot in the middle of the white semicircles at the starting point of your measurement and tap the plus button. 
4. Move the spot in the middle of the semicircles to the ending point of your measurement and tap the plus button.
5. Tap the measurement to see it in centimeters.

To test the accuracy of the measurement, I used a ruler. The Measurement app was 3mm (0.1) off. Depending on the type of band you are considering buying, this could be a small enough margin of error to be just fine. However, if you are considering a Solo Loop, I strongly recommend waiting until you can use a printer and taking advantage of Apple’s official measuring guide tool. Apple’s printed guide offers an Apple Watch size comparison on wrists for a powerful visual reference.

Buying your Apple Watch band on Apple’s website is a great way to ensure you’re getting top quality. Plus, if you get the wrong size, you will be able to exchange it for a better fit.
