>>1991332it kind of depends on the length of your arms and torso
newer MTBs have farely wide handle bars (26 inches wide)
fitting narrower bars (18 to 20 inches wide) can have you sitting more upright
16 inch wide bars are still somewhat usable
there is also the bar shape, but this is a bit convoluted
>flat barleast complex to fit, is the best off road due to allowing a loose grip
>bull moose barfarely wide, nice amount of sweep back, still plenty of flat space for fitting accessory's, fitted to old ATBs
>Nitto B302AA North Roadwide but offers some narrower stance, sweep back comfort depends on handle bar rotation, lots of curves, far less brake and gear lever position options, mostly on city bikes
>Nitto Albatrossmore sweep back, more grip positions and room for brakes and shifters, less clearance for legs (your knees/thighs are getting closer to the bar)
important note is that the larger and taller handle bars are not so good for hill climbing, they flex a bit and place much stress on the Stem
