You’ll need to make sure your standing desk is set to the correct height to see the benefits. Aim to have it positioned at elbow height when your elbows are 90° from the floor.  For example, if you’re 5 feet 8 inches (173cm) tall, a standing height of around 41-42 inches will be about right. But it’s worth measuring this yourself to make sure, including while wearing shoes if that’s something you ever do while working.  If you’re well over 6 feet (183cm) tall, make sure the desk you’re considering goes high enough for you to comfortably use it while standing.
