Under most circumstances, you want the keyboard of your sit-stand desk, or desk converter, to reach a height that allows your arms to bend at 90º when your elbows are at your side, while you are in a standing position.Secondarily, it is ideal for the top of your monitors to reach eye level (or slightly higher).  This isn't always possible with a standard desk or converter, so we strongly recommend that you consider adding a monitor arm to your desk set up.
