The number changes depending on where you look. One article says standing burns 20 to 50 more calories per hour than sitting. A standing desk calculator says 40 to 50. Another site puts the difference at 100 to 200 per hour. Every source sounds confident. None of them cite the same measurement.
The answer comes from the largest analysis of standing versus sitting energy expenditure ever conducted — every reliable controlled measurement published to date, combined into one number.
How Many Calories Does Standing Burn vs Sitting?
Standing burns approximately 0.15 extra calories per minute compared to sitting — about 9 calories per hour. For six hours of daily standing, the total difference is 54 calories. Women experience roughly half the benefit of men. The meaningful calorie gap between sedentary and active people comes from unconscious movement (NEAT), not posture — a difference of 352 calories per day.

Standing burns 0.15 more calories per minute than sitting. Roughly 9 extra calories per hour.
For a 65 kg person standing six hours a day, the total daily difference is 54 calories — less than a single apple. The numbers circulating in standing desk marketing are 4 to 10 times too high. The published conclusion acknowledged these findings were "less substantial than was assumed."
The gap shrinks further for women. Men measured at 0.19 extra calories per minute while standing. Women measured at 0.1 — roughly half. For the average woman standing six hours a day, the calorie return drops to about 36.
Standing still also costs less the longer you do it. Within five minutes of motionless standing, muscle adaptation cuts the energy difference roughly in half. The calorie gap in minute one is about double what remains by minute six. Whether this modest daily difference translates to actual weight loss remains unproven — compensatory mechanisms in appetite and resting metabolism may absorb the deficit entirely.
So standing alone barely moves the needle. But the real calorie gap between people who sit all day and people who move through it is an order of magnitude larger.
Lean people spend roughly 152 more minutes per day upright and moving compared to obese individuals — a gap that persisted even when the obese participants lost weight. Not standing still at a desk. Moving: fidgeting, shifting weight, pacing to the kitchen, stepping down the hall. That movement gap burned about 352 calories per day. More than six times what standing alone provides.
STANDING
54 cal/day from posture alone
MOVING
352 cal/day from NEAT movement gap
This is NEAT — non-exercise activity thermogenesis. Everything your body burns through movement that is not deliberate exercise. In controlled overfeeding, NEAT explained two-thirds of the total metabolic response when participants consumed a thousand extra calories a day. The person who gained the least fat was not the one who stood more. It was the one whose body unconsciously moved more.
A standing desk does not burn meaningful calories because you are standing. It may matter because standing removes the constraint that sitting imposes on movement. The desk is not the calorie tool. It is the permission slip.
And if that movement gap — 352 calories a day — persists regardless of weight loss, the standing desk's real value is not about 9 extra calories. It is about whether your body is the kind that responds to freedom by moving.
