Mine is 36" from the floor. I can stand and reach all the way across (table is 4 ft' wide), but I don't have to bend very much when working at it standing up. A bar stool works for me to sit down when I want, I trimmed the legs a little. I'm 5'11" and the tabletop hits me right where I bend at the hip. I also have back pain, so height was important to me, too, but I wanted to be able to reach across the table.. If you don't have as wide a table, maybe a tad higher would work better for you.
