This seemed like the most suited forum for my question

I'm looking to get a new monitor. Presently I'm using a 17" on my laptop. I'm going to build a new computer and want a monitor for precision photo editing, but I'd
like to improve my map-making skills as well. My desk is a typical 24" deep, thus the monitor probably sits about 18" away from the edge. Maybe 20" from my face. With this in mind...can I go "too big"? Would a 32" 4k just be a gigantic beast of overkill or would it be advantageous? At this time (gimp), I usually have tools on the left and dialog boxes on the right. This, of course, tends to both center the canvas as well as reduce it's area a bit.

Any thoughts or recommendations would be most appreciated
