What chair height works best with a standard L-shaped desk?

At a standard 29"–30" desk height, your ideal chair seat height puts your thighs parallel to the floor and your feet flat — for most adults this means a seat height of 17"–21" depending on leg length. Your elbows should be at roughly desk height when your arms are relaxed, and your monitor should be at eye level. If the desk height is fixed and your chair can't accommodate your build, a keyboard tray (which lowers the typing surface) is the best workaround.
