What is the best screen size for coding?

Question

Iron

Good day to all.
I'm looking for a new monitor in the segment up to 20k rubles. I can’t decide which diagonal would be better: 24 or 27.
The characteristics of all the models that I looked at are approximately the same for both diagonals. So what would be better for working with code (IntelliJ Idea) and surfing the web: 24 or 27 inches?
Please share your opinion and experience.
Viewed models that interested me Dell P2717H & Dell P2417H and Samsung S24E390HL & Samsung S27E390H . The comparison does not show a big difference between variations of 27 and 24 inches. Is that the dimensions, power and brightness are slightly different.
I will also be glad to hear any other suggestions from you.

Answer 1

More conveniently two to 23

Answer 2

I have one main house 27, the second 21 (for the terminal).
At work, the main 27, the second 24 (also for the terminal).
In general, it is convenient to work with the code. Although I have seen dudes who work on 13 inch macbooks without external monitors and do not know the problems.
So it's all a matter of habit and taste.
