How Calories Burned Playing Tennis Are Calculated
Calories burned playing tennis is the energy your body uses to hit, run, and recover on court. Your weight, your time on court and the kind of tennis you play matter most.
What Tennis Calorie Estimates Measure
The number is your total energy use on court, and because it includes what your body would burn at rest anyway, it is a gross figure. It does not read your heart rate, oxygen use, or fitness.
The Formula
Calories (kcal) = MET x body weight (kg) x time (hours)
1 MET = about 1 kcal per kg of body weight per hour
A MET puts the effort of an activity next to sitting at rest. Tennis values come from the 2024 Adult Compendium of Physical Activities, which lists both measured and estimated energy costs for adults aged 19 to 59¹.
How This Calculator Computes Your Result
After choosing your age group and entering your weight in pounds or kilograms, pick the type of tennis and enter your time in hours and minutes (Whole session, the default). The tool then converts pounds to kilograms, finds the MET for the tennis you picked, and multiplies. Totals are rounded to the nearest 5 kcal, and the MET is given to one decimal place.
Type of tennis | Compendium code | MET |
Hitting practice (rallying or drills, no scoring) | 15695 | 5.0 |
Doubles, social | 15685 | 4.5 |
Doubles, steady rallies | 15680 | 6.0 |
General play, moderate effort | 15675 | 6.8 |
Singles or competitive play | 15690 | 8.0 |
There are two doubles values, so pick the one that fits your game. Competitive play (15676) has the same 8.0 as singles, so they share one option¹. Hitting practice is an estimated value, not a direct measurement.
Next to your total, you see calories per hour of play and per 30 minutes, plus a table of all five tennis options at your weight. If you are under 18, you will not see a tennis result, because youth values differ. At 60 and over you see the adult result with a note that values for older adults may be lower, because the Older Adult Compendium has no tennis entry.
Split my session (optional). Not all court time is tennis. This helper takes three parts: warm-up minutes (counted as hitting practice), playing minutes (counted at your chosen type), and long breaks such as changeovers, drinks, or waiting for a court (left out, so the result is labeled active time only). Do not subtract the short pauses between points. Measured tennis values are averaged over whole games, so those pauses are already counted².
What Your Result Means
It tells you the energy that tennis session used, not how much you should burn. A 70 kg (154 lb) adult burns this much playing tennis:
Type of tennis | 30 minutes | 60 minutes |
Hitting practice | 175 kcal | 350 kcal |
Doubles, social | 160 kcal | 315 kcal |
Doubles, steady rallies | 210 kcal | 420 kcal |
General play, moderate effort | 240 kcal | 475 kcal |
Singles or competitive play | 280 kcal | 560 kcal |
An hour of singles burns roughly 1.3 to 1.8 times as much as an hour of doubles. Body weight matters too: at the same effort, a heavier player has more to move and burns more.
What Changes Your Burn on the Court
Singles or doubles. In singles, the whole court is yours to cover. In doubles you share it, and you often stand at the net. That is why the compendium values for doubles sit well below singles¹.
How much of the time the ball is in play. Tennis is stop and start. In a study that measured 10 matches with portable gas analysers, the ball was in play only about 29% of the time, and the average rally lasted 6.4 seconds². Short, near-maximal bursts alternate with longer spells of moderate or easy activity³.
Rally length and style. In the same study, rally length was the strongest single predictor of oxygen use. Games between two defensive, baseline-style players cost more than games with at least one attacking player².
Level, surface and ball. Match intensity also changes with skill, sex, court surface, and ball type³.
What Studies Measured During Real Matches
In the match study above, 20 players wore portable gas analysers during 50-minute singles matches. Their average oxygen use was 29.1 mL per kg per minute². Divided by 3.5 (the resting value behind 1 MET), that is about 8.3 METs, close to the compendium's 8.0 for singles. But single games ranged from about 3 to 14 METs, so one session can land far from the average².
For doubles, a Japanese study measured one set with a portable oxygen meter. Trained tennis players used 0.102 kcal per kg per minute and untrained men 0.096⁴. That is about 6.1 and 5.8 kcal per kg per hour, in line with the compendium's 6.0 doubles value.
Tennis Compared With Other Racket Sports
Tennis against other sports for one hour, using 2024 Adult Compendium values¹:
Activity (code) | MET | 70 kg (154 lb) | 90 kg (198 lb) |
Tennis, singles (15690) | 8.0 | 560 kcal | 720 kcal |
Squash, general (15652) | 7.3 | 510 kcal | 655 kcal |
Badminton, competitive (15020) | 7.0 | 490 kcal | 630 kcal |
Tennis, doubles (15680) | 6.0 | 420 kcal | 540 kcal |
Paddleball, casual (15500) | 6.0 | 420 kcal | 540 kcal |
Badminton, social (15030) | 5.5 | 385 kcal | 495 kcal |
The compendium has no separate entry for pickleball or padel. Both are mostly played as doubles on a smaller court, so the closest stand-ins are tennis doubles and casual paddleball. The compendium's other squash row (15650), often used for hard play, is 12.0 METs, well above any tennis row¹.
A Note on Accuracy
Two players can spend the same hour on court very differently. A baseline player stuck in long rallies and a club doubles player who waits at the net may both "play an hour" and burn very different amounts². Skill matters too: in the doubles study, trained players used a little more energy than untrained men⁴. On top of that, the compendium uses an average resting rate, and your own may be higher or lower¹. Think of your tennis result as a fair estimate rather than an exact count.
Frequently Asked Questions
How many calories does an hour of tennis burn?
A 70 kg (154 lb) adult burns about 315 to 420 kcal in an hour of doubles, 475 kcal in moderate general play, and 560 kcal in singles¹. A heavier player burns more.
Does singles burn more calories than doubles?
Yes. The compendium lists singles at 8.0 METs and doubles at 4.5 to 6.0, because singles players cover more court and play more of the points¹.
Is tennis good exercise?
Every tennis value in the compendium is 4.5 METs or more, well above rest¹. In a study of over 80,000 British adults followed for about 9 years, people who played racket sports had a 47% lower risk of death from any cause, though this kind of study cannot prove cause and effect⁵.
How accurate is a tennis calorie calculator?
The tennis figure is a reasonable average and not an exact one. Measured matches show that rally length, playing style, and skill can push your real burn well above or below the estimate².
