I don't care for WIDE bars, so I took a tape and went thru several FLAT bars to find mine, approx. 24 inches from end to end. I don't have long arms but didn't want to have to "cut" bars so I took the time to find the exact bars I wanted. I have both egro grips and bar ends so my cockpit is "compact" but it makes the steering quicker which I like.
Now road bike bars would be tough for me, I always like the "randoueer(sp?)" type bars better than a "mace" type racing bars on my 80's touring bikes. I don't know if you can even get that kind of bar today, hope so as I might just talk myself into a "drop bar touring bike", this Spring.
