Calories Burned Playing Tennis:

How calories burned playing tennis are calculated
This calculator uses the standard MET (Metabolic Equivalent of Task) method published in the Compendium of Physical Activities. One MET is the energy cost of sitting at rest — roughly 1 kcal per kg of body weight per hour. Tennis is assigned a MET value based on whether you're rallying lightly, playing doubles, or competing in singles.
Calories = MET × Weight (kg) × Duration (hours)
The MET values used here for each pace come directly from the Compendium of Physical Activities (Ainsworth et al. 2011), the same reference used by ACSM and most fitness research:
| Tennis intensity | MET value | Typical context |
|---|---|---|
| Practice serve / casual hitting | 5.0 | Stationary or short, low-effort rallies |
| Doubles match | 6.0 | Half-court coverage, moderate sprinting |
| Singles match | 8.0 | Full-court coverage, continuous play |
Worked example with the calculator defaults (74 kg, 20 minutes, practice serve at 5.0 MET):
- Duration in hours = 20 ÷ 60 = 0.333 hours
- Calories = 5.0 × 74 × 0.333 = about 123 calories
Switching to singles (8.0 MET) at the same weight and duration roughly 1.6×'s the burn to around 197 calories — a useful reminder that intensity matters more than time on the court.
Calories burned by intensity and body weight
The table below shows estimated calories burned over a one-hour session at each tennis intensity, across common body weights. Use it to sanity-check the calculator output or to compare against other activities.
| Intensity (MET) | 60 kg (132 lb) | 75 kg (165 lb) | 90 kg (198 lb) |
|---|---|---|---|
| Practice serve (5.0) | 300 kcal | 375 kcal | 450 kcal |
| Doubles (6.0) | 360 kcal | 450 kcal | 540 kcal |
| Singles (8.0) | 480 kcal | 600 kcal | 720 kcal |
| Competitive singles (10.0) | 600 kcal | 750 kcal | 900 kcal |
A practical takeaway: for an average-weight adult, an hour of singles burns roughly the same calories as 35–40 minutes of running at a moderate pace — with the advantage of being far more enjoyable for most people.
Limitations of MET-based estimates
The MET formula is a good starting point, but it has known weaknesses for stop-start sports like tennis:
- MET values are averages. The 8.0 figure for singles is a population average. Individual energy cost varies by skill, fitness, and how aggressively you play — expect ±15–25% even on identical-looking matches.
- Tennis is intermittent. Actual play time during a one-hour match is typically only 20–30 minutes; the rest is between-point recovery. MET tables already account for this in the average, but if you play a faster format (no-ad scoring, shorter breaks) you'll exceed the estimate.
- EPOC is not included. Singles tennis is high-intensity intermittent exercise, which produces excess post-exercise oxygen consumption — an additional 6–15% of session calories burned in the hours after play. The calculator ignores this.
- Skill efficiency matters. A beginner running back and forth chasing every ball burns more than an efficient pro covering the same court with better positioning — the opposite of what intuition suggests.
- Equipment and conditions. Heat, humidity, heavier rackets, and clay vs. hard court all shift the actual energy cost by a few percent in either direction.
Treat the number as a reasonable estimate, not a measurement. Tracking over weeks gives a better signal than any single session's reading.

FAQs
Yes, and the gap is meaningful. The Compendium of Physical Activities assigns singles tennis a MET value of 8.0 and doubles 6.0 — roughly 33% more energy expenditure per minute in singles. The reason is court coverage: in singles you defend the full width alone, so total running distance during a match is typically 1.5–2× that of doubles. Over an hour, a 75 kg player burns about 600 calories playing singles versus 450 in doubles.
MET-based calculations are generally accurate to within ±15–25% for tennis because actual intensity varies so much. Two players in a "singles" match can have very different burn rates depending on rally length, skill level, and how aggressively they move. The estimate is most accurate for steady, continuous play and least accurate for casual hitting with long pauses between points.
Surface has a small effect. Clay courts produce longer rallies (the ball bounces higher and slower), which can modestly increase total calories burned per match. Grass and hard courts favor shorter, more explosive points. Across a one-hour session the difference is usually less than 10% — far smaller than the difference between singles, doubles, or competitive vs casual play.
Competitive singles (8.0+ MET) burns roughly 60% more calories per minute than practice serving or casual rallying (around 5.0 MET). For a 75 kg player over an hour, that's about 600 calories competitive versus 375 calories practice. Tournament-level singles can exceed 10 MET during long matches when sprinting and recovery overlap.
EPOC — excess post-exercise oxygen consumption — adds roughly 6–15% on top of the workout calorie total for intermittent, high-intensity sports like singles tennis. The MET formula does not include this. If the calculator estimates 500 calories burned, total energy cost including recovery may be closer to 530–575. For doubles or casual play the EPOC contribution is smaller because peak intensity is lower.
