For my use I'd say 27 inch is too big for what I currently do on my computer. I used to do video editing years ago and I liked the bigger screen, but now all I do is basic stuff like Pages, Safari, etc. so 24 inch seems to be my sweet spot. My desk isn't that big and the 32 inch monitor took up too much space, and I found myself having to turn my head a lot to see the entire screen, and most of the content I'd view would have massive white sides to them and wouldn't take advantage of the big size (except watching shows, it was nice for that!). I used to get the biggest sized screens Apple sold, but over the last 2 years I went from an iPhone 7 Plus to a 12 mini, 12.9 iPad Pro to an 11 inch, and now 27 inch to 24 inch for some reason. I also sold my 13 inch MBP and I'll use my iPad in its place (basically only use it for Pages). If you do a lot of creating or entertainment, I would say 27-32 inches is perfect, but if you do more day to day stuff, then 24 inch is likely a sweet spot too!
