I think my desk is about 90cm deep, I’d say I stay about 100/120cm from my eyes to the display.
Sometimes I just don’t place things to the edges or the very bottom. A 37” or 40” display would suffice but I didn’t find any, and 32” is too small imho.
That makes sense. When I say "sitting back" I mean leaning back, which is closer to the real distance I should be.
I downsized my desk significantly when we had kids so that's the reason for sitting so close. We're currently working on resolving the space situation then maybe I too can switch to a monster sized monitor!
