The average person burns 75-100 calories resting or doing nothing. Standing or fidgeting doesn’t count as it burns more calories per hour. In round figures a person doing nothing will burn approximately one calorie per hour per kilogram of bodyweight (a half calorie per pound). If properly sleeping (as opposed to short naps), they will burn fewer calories per hour.
In terms of relative calorie burn, standing burns roughly 90% more calories than sitting.
Below is a more accurate calorie burn for standing (the difference between the 2).
