Same here.i am 6'2" and i went w/ 42" for my workbench.
I go elbow height, dang near the same thing.I like "bellybutton, plus 2 inches" for benches that I stand at.
Build a 42" bench with a portion of 36" bench. Best of both worlds.
I'm 5'9" and mine is 36". You're taller than me but our arms must be the same length.I'm 5'10" and I built mine at 37"... works for me.

My back is pretty good but about 25 years ago I built my parts washer with the basin floor at the same height as my bench (36") specifcally to avoid getting a sore back when I used it. I have never regretted that - it works great.I'm 6'2" and the last one I built was higher than 36", probably about 40". I have back issues so need the height to avoid leaning over too much. for my new garage I'm thinking of a similar height for standing at and maybe a lower one for sitting at.
Something else to consider... If you're going to put shelving below or store things below the bench, you may want to measure the things you're going to store there. It'd **** to build your bench THEN find out that stuff won't fit under it. Just a thought.
I'm 5'9" and built my first set of workbenches at 42". That was a little too high.
The ones I'm building right now are 40" which I think will be just right for standing or working on a stool.
I can work standing up all day long, but 10 minutes of "hunched over" work just kills my back/neck, so I'd rather err high.
