Determining Which Apple Watch Size Is Right For You

Mike Harmon

When choosing an Apple Watch, it’s important to find the right size for your wrist to ensure a comfortable fit. Apple offers a variety of models and sizes to suit different wrist sizes and preferences. Whether you’re purchasing a new Apple Watch or upgrading, it’s important to know how to measure your wrist and select the correct size. To determine your Apple Watch size, you need to know the dimensions of the watch case. Previous models such as the SE, Series 4, 5, and 6 were available in 40mm and 44mm sizes, while newer models like the Series 7, 8, and 9 come in 41mm and 45mm sizes.

For those with larger wrists or who prefer a bigger display, the Apple Watch Ultra is available in a 49mm size. You can find the size of your current watch by checking the engraving on the back of the watch case or looking at the model number through the settings in the Apple Watch app on your iPhone. It’s also important to select the right Apple Watch band for a good fit. Bands come in different materials and sizes, so it’s essential to match the band with the watch case size and ensure it fits comfortably on your wrist. If you’re unsure of your wrist size, Apple provides printable tools to measure your wrist, or you can use a ruler to measure directly. This ensures that the band you choose complements both your watch and your wrist size.

Sizing Up Your Apple Watch

Wrist Size is Key

To find the perfect fit for your Apple Watch, start by measuring your wrist. This is important! Use a tape measure or a piece of string to find the circumference of your wrist. This measurement will help you determine the best band size for your watch. Apple offers bands in a variety of sizes to fit different wrists. You’ll find options for both the smaller and larger Apple Watch models.

Choosing Your Watch Size

There are two sizes available for each Apple Watch model: a smaller and a larger option. The size refers to the dimensions of the watch case itself, not the band size. If you prefer a more compact watch, go for the smaller option. Those who like a larger display and a bolder look should opt for the larger size. It’s really a matter of personal preference!

Try It On Virtually

Don’t have access to a physical Apple Store? No problem! Apple makes it easy to “try on” their watches virtually. You can use the Apple Store app to see how different watch sizes and bands would look on your wrist. This is a great way to get a feel for the different options before making a purchase.

Band Size Chart

Apple provides a handy chart that shows the corresponding band sizes for their different watch models. Be sure to consult this chart when choosing a band for your watch. It’s important to choose the right size to ensure a comfortable and secure fit.

Key Takeaways

Understanding Apple Watch Sizing

Choosing the correct Apple Watch size ensures comfort and readability. This section covers differences across Apple Watch series, case dimensions, and wrist measuring.

Differences Across Series and Models

Every Apple Watch series has distinct case sizes. The Apple Watch Series 3 comes in 38mm and 42mm cases. Series 4, 5, and 6 offer 40mm and 44mm. The Series 7, 8, and 9, along with the SE, introduce 41mm and 45mm sizes. The Apple Watch Ultra and expected Ultra 2 present the largest at 49mm.

Case Size and Dimensions

Case size determines screen size and overall watch size. The 40mm and 44mm dimensions are popular and fit most wrist sizes. They have these dimensions:

  • 38mm case: 38.6mm height by 33.3mm width
  • 40mm case: 40mm height by 34mm width
  • 41mm case: 41mm height by 35mm width
  • 42mm case: 42.5mm height by 36.4mm width
  • 44mm case: 44mm height by 38mm width
  • 45mm case: 45mm height by 38mm width
  • 49mm case (Ultra models): 49mm height by 44mm width

Apple Watches fit both small and large wrists by adjusting the band.

Measuring Your Wrist for the Perfect Fit

Use a flexible tape measure around the wrist where the watch will sit. Record the wrist circumference. If the measurement falls between two sizes, choose the smaller for a snug fit or the larger for room. Here’s a wrist size guide:

  • Small: 130-180mm
  • Medium: 140-190mm
  • Large: 160-210mm

Matching your wrist size to the case size ensures the Apple Watch fits well and functions as desired.

Selecting the Right Apple Watch Band

Choosing the right Apple Watch band requires considering band types, sizes, and compatibility with your Apple Watch model. This ensures comfort and a secure fit on your wrist.

Band Types and Their Sizes

Apple Watch bands come in various styles and materials, each with its own sizing options. The Sport Band and Sport Loop are silicone and nylon bands with an adjustable strap for a wide range of wrist sizes. Sports straps with Velcro offer a secure fit with ease of adjustment. The Milanese Loop is a metal mesh with a magnetic closure, allowing for subtle adjustments. Leather options include the Modern Buckle, which has a magnetic closure and comes in multiple sizes for precision fit.

The Solo Loop and Braided Solo Loop bands are unique as they don’t have clasps or buckles and are sold in 9 different sizes. The Link Bracelet provides a professional look, sized by adding or removing links.

Band sizing typically ranges from 130 – 200mm for wrist circumference, depending on the band style and material.

Compatibility with Different Apple Watch Models

Apple Watch bands are designed to be compatible with specific case sizes:

  • 38mm and 40mm Bands: These are interchangeable and fit wrists from 130mm to 200mm.
  • 42mm and 44mm Bands: These also fit interchangeably and are suitable for wrists from 140mm to 220mm.

When selecting a band, identify your Apple Watch model number and case size. The model number is found on the back of the watch or in the watch settings under the “About” section. Once you know the model number and size, you can choose a band that matches. For example, if your Apple Watch case size is 40mm, select bands designed for either 38mm or 40mm models.

Remember, bands made for a 38mm or 40mm case will not fit a 42mm or 44mm case, and vice versa.

Band compatibility is easy to determine; just match the band size to your Apple Watch case size. Apple provides a guide on their website on how to measure your wrist and a chart matching wrist measurements to band sizes. This ensures you get a band that not only fits but is also compatible with your model.

How to Choose the Right Size

When selecting an Apple Watch, consider the following:

  • Wrist Size: Measure your wrist to see which case size would be more comfortable.
  • Screen Size Preference: If you prioritize a larger display, opt for models with thinner bezels and larger screens.
  • Usage: Think about how you plan to use your watch. If it’s for fitness tracking, a larger screen might be beneficial.

Utilizing the Serial Number

You can also identify your Apple Watch model or series using the serial number. Visit the Apple Check Coverage page and enter your Watch serial number. To find this number, open the Watch app on your iPhone, select the “My Watch” tab, tap “General,” and choose “About”​​.
