I know this is a old topic, but for anyone interested I thought I would post my 2 cents worth. Fact is no matter your height, we are not built the same. I have been building a bunch of mobile stands of late for various tools, and in comparison to store bought tools etc and my little harbor freight workbench I bought, I think stuff is designed for dwarves. I'm only 5'11" but I find if I have to spend much time at all hunched over something at my age that my back starts to ache. Tonight I spent over a hour working with my Ridgid oscillating sander smoothing some boards and when I was done was just as good when I started. I believe it's cause the stand is set up so the table is at a perfect magic 42" in height. Now the trick is everyone's magic number may be different, but it is easy to find I believe. Eyesight of course could change things, but given normal eyesight, have someone measure from the ground to the bottom of your elbow with your arms at a 90 degree angle from your body. No bending, your arms rest comfy on whatever tool. Take tool height and subtract that along with coasters etc and you have the stand height. I have a post about my HF workbench on here in another thread, and even though it is not up to 42" it is so much more comfy after I jacked it up 4" with a mobile stand. I may build some risers for it soon to bring it to that spec.
