The Apple Watch Series 9 comes in two sizes, 41mm and 45mm, but the question is, which should you get? Today I have both sizes to compare and show you how they look on my wrists, as well as to see how WatchOS differs on each, and finally talk about the pros and cons of both sizes - to help you decide which is right for you!

Thank you. This video saved me a lot of research. Picking up the 41 today.

[TocaCalla]

Both look great, but I'd definitely go for the 41 mm version since I have a small wrist. Also, another informative video!

[drinkingpoolwater]

i just bought the 41mm series 9 after always wearing the 45. i get annoyed at how big it is so figured i'd try the smaller one.

[JRB]

I have the 45mm, Series 9. I thought it would look/feel WAY too big, but it really isn’t. Get the 45mm! The Apple Watch Ultra is too big, though.

[ludvigodling]

What do you think of these cases/protective glasses for the Watch? Ive tried both but i feel that both options reduce the touch sensitivity in a big way and the display does not look as good, almost as the colours gets a bit washed out. Have i just made a mistake with buying cheaper cases/glasses? Any tips?

[UncleLinds]

Thank you so much! This was extremely helpful. I just ordered the 41mm from Verizon with 2 day shipping only to be informed AFTER completing my purchase that my selection is backordered and won’t even ship for at least 3-4 weeks. I was considering changing my order to a 45mm instead (in case if it might be in stock), because 41mm to 45mm size didn’t seem like that big of a difference to me in theory. Howrver, after seeing them worn & side by side in your video, I realized the size difference is much more significant than I had thought, and the 45mm would definitely be WAY too big for my relatively small wrists/hands. Now, that I know the 41mm is undoubtably the right choice for me, I can gladly/patiently wait those extra backorder weeks without regrets or any second guessing.

I usually go for screen size, but am wanting a watch to track health data including while I sleep so I think 41mm will be the right choice since functionality is identical

[edwinadel]

I hope that they release a 43mm version of the Apple watch. Because it would be the perfect in between.

Is protection really necessary if you don’t purchase the stainless steel build

[JustHyden]

I feel like 41 is more in line with a watch size, though it may just be my smaller wrists, or the ui looking a bit off for a larger display

[markepperson]

Im enjoying the watch 9, 41mm, i have a thin wrist, this is my first apple watch, and my first iphone since the iphone 4, yes, 4. Which is a 12, both work flawless together.

[ashon]

So many reviews, but few talk about elegance. This is what I was looking for.Thank you ❤

[LizXing-vfoj]

Is the text size the same between Apple Watches?

[sarahgodshall]

I just upgraded from having an Apple Watch Series 7 to an Apple Watch series 9. I really do love how fast the series 9 charges. I’m still learning some of the new features that weren’t on the series 7 watch.

@firerains

I prefer the 45mm because my hands are big, but I would get the 41mm for the price

[pallavdas]

The feature I like or am looking forward to on the series 9 is the tap function which allows not to touch but snooze or reject calls

[damlakbao]

@damtammy

I recently purchased Series 9 41mm. I think it’s best to use it from day to day wearable. I like how it’s very responsive when using the double tap.

[ANeo-qcsz]

I have very small wrist but I like big watches face, even for dress watch. Like the contrast and the comfort of reading off bigger screen. Hence definitely 45mm for me ！ but I agree that big face make it looks more like a gadget than watch on wrist. Thanks for the detailed comparison.

[Bigjdog]

A lot of times when I wear a watch I forget it’s on and hit things would you say that the watch case could handle this or would I need to get a different case?

[bpago]

Really informative . thanks .
When a watch is measured is it diagonal from corner to corner (Like a TV) is that screen only or the actual housing as well? I plan on cutting a cardboard shape to check how the size looks . (Apple should provide a template like tis to print ...
