Standing vs Sitting Calories Calculator

Standing burns more calories than sitting, because the muscles in your legs, core, and back have to stay engaged to keep you upright. The honest headline is that the difference is small. Smaller than most standing-desk marketing suggests, and smaller than the number this page used to print.

The Formula

Calorie burn is based on MET (Metabolic Equivalent of Task) values, which measure how much energy an activity requires relative to rest:

Calories per hour = MET × body weight (kg) × 1.05

Where the standing figure comes from, and why it is not 1.8

This is the part worth reading. The Compendium lists standing quietly at 1.3, exactly the same as sitting - it does not credit standing with any extra burn at all. Meanwhile plenty of calculators use 1.8, which would make standing worth about 37 kcal an hour for a 70 kg adult.

Neither is right. A 2018 meta-analysis pooling 46 studies that put people in a metabolic chamber found the real difference between sitting and standing averages 0.15 kcal per minute, which is 9 kcal an hour. That works out to a standing MET of roughly 1.45 for a typical adult, and it is the figure this calculator uses.

What This Means in Practice

For a 70 kg (154 lb) person:

• Sitting 1 hour: 1.30 × 70 × 1.05 = 96 kcal
• Standing 1 hour: 1.45 × 70 × 1.05 = 107 kcal
• Difference per hour: 11 kcal

Over an 8-hour workday that is about 88 extra calories. Over 250 workdays, 22,050 calories, or about 2.9 kg (6.3 lbs) of body fat on paper.

On paper is doing real work in that sentence. Trials that actually weigh people who switch to standing desks find much less change than the arithmetic predicts, because appetite rises a little and people move slightly less the rest of the day. Nobody has lost 20 lbs by standing up.

So is a standing desk pointless?

No, but pick the right reason. The evidence for standing desks is decent on back pain, postprandial blood glucose, and self-reported afternoon alertness. It is weak on weight. Buy one for your spine, not your waistline.

The lever that does move calories is walking. The same eight hours spent in light walking rather than sitting is 882 kcal, ten times what standing buys you. That is why treadmill desks and walking meetings show up in the literature and plain standing does not.

Standing Desks in Practice

Alternating between sitting and standing every 30 to 60 minutes beats standing all day. Prolonged standing causes its own problems: leg fatigue, and there is reasonable evidence linking all-day standing work to varicose veins. A rough 1:1 split through the day is the usual recommendation.

Tips to Increase Calorie Burn While Standing

• Shift your weight from foot to foot
• Use an anti-fatigue mat for comfort
• Do calf raises or small movements while standing
• Walk during phone calls - this roughly doubles the calorie burn

Note on Accuracy

Individual results vary based on fitness level, posture, muscle mass, and how still you actually stand. These values are estimates based on MET averages and are suitable for general planning purposes.
