It may not be immediately obvious, but there are a couple of things to know about Apple Watch sizes before you buy. No watch is one size fits all, and Apple has addressed this in its much-loved smartwatch range. We’ll cover everything here, so you know what to look for and—hopefully which will work best for you.

What Apple Watch sizes are available? 

The most common sizes of the Apple Watch are the 40mm and 44mm models. However, there is some difference between some of the sizes for the various series of the Watch.

Apple Watch size guide 

These are the sizes available in each series, from series 3 onwards. 

  • Series 3 = 38mm and 42mm 
  • Series 4 = 40mm and 44mm
  • Series 5 = 40mm and 44mm 
  • Series 6 = 40mm and 44mm 
  • SE = 40mm and 44mm 
  • Series 7 = 41mm and 45mm

The band sizes available for your watch will be dependent on the size of the Apple Watch case. What some consumers accidentally do is purchase a replacement band that they prefer, but get the sizing all wrong. 

You can actually use bands from all series of Apple Watch, as long as the case is compatible. So, here’s what you need to remember: 

  • Bands suitable for 38mm, 40mm and 41mm can all fit the cases of each other 
  • Bands suitable for 42mm, 44mm and 45mm can all fit the cases of each other 

Which size is right for me?

 Which Size Is Right For Me? 

There are several factors to consider when choosing the right size. These include your height, weight, activity level, and budget. We’ve outlined all the information you need to make the right decision here. 


Your height can determine which size Apple Watch is best for you. If you’re short, you’ll find the large Apple Watch is too big and uncomfortable.

On the contrary, if you’re on the taller side, then the smaller Apple Watch is likely too small and may feel awkward on your wrist. 


Your weight can also determine what size Apple Watch is better suited for you. If you weigh less than 100 pounds, the series 5 38 mm Apple Watch is a good choice.

The smaller size means it fits comfortably on your wrist and is easier to manage. On the other hand, if you weigh over 150 pounds, the 42 mm Apple Watch or even the series 7 may be your go-to option. It’s wider and thicker making it more suited.

Activity level 

Finally, your activity level can help you decide which Apple Watch size is best for you.

Those who participate in rigorous physical activities such as running, cycling, and swimming will benefit most from the larger models, due to its larger screen, making it easier to utilize the features.

Types of Apple Bands 

There are three types of band options available for the Apple Watch. Each type has its own pros and cons, so we’ve listed them below along with their prices. 

Sport band 

This band is made using fluoroelastomer, which is surprisingly durable given how lightweight it feels on your wrist. It also features an innovative “tuck and pin” closure, helping to ensure the watch stays securely on your wrist at all times. 

This band is ideal if you want something lightweight and easy to slip on and off. However, this style doesn’t offer much support and is not recommended for those who exercise regularly. 

Classic buckle 

This band is made out of stainless steel and it features an adjustable clasp closure and buckle. 

If you prefer a sturdy yet stylish band then this one is perfect for you. It offers excellent support and is great for daily use. This style is also great for fitness enthusiasts as it won’t interfere with any workout activities. 

Milanese loop 

This band is handmade and crafted from genuine leather.. It features a double-sided clasp closure and buckle. This is our favorite option for everyday use. 

It’s durable, flexible and looks great on just about anyone. It’s also very affordable compared to other styles. 

Is the Apple Watch worth buying?

This is of course going to be subjective to you. However, many users have never looked back after buying their first Apple Watch. 

If you’re not used to wearing a watch and you’re not sure if you will use the watch to its full potential, consider wearing a regular watch for a week and getting used to putting it on every day. 

If you can get used to this, an Apple Watch will be like your regular watch but with amazing features!

Is the Apple Watch better than Samsung Galaxy Watch?

This again is subjective. Both watches are great pieces of wearable technology and both have their own pros and cons. 

If you are in the market for a smartwatch and you’re not sure which is best for you, ask a friend who has one or go into a store and see if you can test them. 

Apple watches generally are preferred by Apple technology users, whereas Samsung is often preferred by Android technology users. So, maybe consider this before buying.

Bottom line

It can be difficult to choose between the two options, but the key factors to remember are the larger watches tend to be more costly, but there’s a rationale for this.

Larger people (in height and weight) should consider the larger option and vice versa. If you’re not used to wearing a watch but would like to start wearing an Apple Watch, it may be a good idea to try out both sizes at the store first before you buy.
