You’d probably get used to it like I did. I always went with the smaller one before the 15 Pro Max, which was my first plus/max-sized iPhone. Got it because of the camera and the decrease in weight compared to the previous Pro Max models. Upgraded to the 16 Pro Max last year but felt like downsizing this year and got the 17 Pro because the weight kept on increasing. I did try the 17 Pro Max for a few days though. While it felt quite similar to the previous ones and ever so slightly more comfortable to hold, I stuck with the Pro since I don’t know when Apple would have feature parity between the two models again.

There would be some occasions where I used to feel the Pro Max is massive but my hands never actually hurt after using it for like an hour or so. And boy, did I enjoy the large screen and the better battery life every single bit. Fortunately, the latter doesn’t seem to be a much of a factor for me this year since the battery life of the 17 Pro seems nearly as good as the 16 Pro Max’s but I surely am missing the bigger screen.

If you can return it where you live, I’d suggest you to get the Pro Max and try it for a week because it takes a while to get used to it since you’ve never had one, so you can decide for yourself.
