28" or 32" 4K monitor?

Thinking ahead for my 4K upgrade later this year.
I can't for the life of me work out whether I should go for a 28 or 32 inch.
This is my current 2x 23" 1080p setup (I only game on the left one).

I will be using the 4k monitor for both gaming and watching netflix/youtube. But in the second instance I will be sitting further back.

I have to say I think I would definitely go for 30" if it was available but it doesn't seem to be an available size. Would 32" be obscene? or is it worth it at 4k?

Thanks.

Im thinking 32" and stick it on the wall. Freeing up deskspace too.
