Estimate calories and kilojoules burned playing tennis, based on your body weight, how long you played, and whether it was casual ball-hitting practice, a doubles match, or a singles match. Built with Australia's club and backyard tennis culture — and the annual rush to the courts every Australian Open summer — in mind.
Tennis calorie burn depends heavily on the format, captured here as three tiers: hitting balls in casual, non-game practice (MET 5.0), a doubles match (MET 6.0), and a singles match (MET 8.0). The formula is calories = MET × body weight (kg) × playing time (hours). A 70 kg player who spends 60 minutes on court in a singles match burns around 560 kcal, about 2,343 kJ — noticeably more than the roughly 420 kcal (about 1,757 kJ) the same player would burn in an hour of doubles, and meaningfully more again than the roughly 350 kcal (about 1,464 kJ) burned in an hour of casual hitting or practice with no real match pressure.
| Playing Style | MET | Calories | Kilojoules |

The calculation combines three inputs: a MET (Metabolic Equivalent of Task) value for how competitive and continuous your tennis actually was, your body weight, and the time you spent on court. This calculator uses three MET tiers drawn from the tennis activity codes in the 2024 Adult Compendium of Physical Activities — hitting balls in non-game, moderate-effort practice (code 15695, MET 5.0), doubles play (code 15680, Taylor Code 430, MET 6.0), and singles play (code 15690, Taylor Code 420, MET 8.0) — because whether you're rallying casually, sharing a court with a partner, or covering the whole court alone in a scored match changes how hard your body is working far more than the basic act of hitting a tennis ball does.
The MET gap between doubles (6.0) and singles (8.0) reflects a fairly intuitive difference in workload: in singles you are the only player on your side of the net, so every ball hit anywhere into your half of the court is yours to chase, and every point requires you alone to cover the width and depth of the whole singles court. In doubles, that same court — actually a narrower slice of it, since doubles is played on a wider court but each partner effectively covers roughly half the ground — is shared between two players, which means more standing, positioning, and recovery time between the shots you personally have to run down. Less ground covered per point, shared across more players, adds up to a real difference over 60 minutes of play, even though both formats are unmistakably "tennis" by any casual description.
Hitting balls in casual, non-game practice sits lowest of the three tiers for a related but distinct reason: there's no rallying intensity or match pressure driving continuous movement. A practice session often involves a coach or partner feeding balls, pauses to reset position or adjust technique, and shots hit at a controlled pace rather than the reactive scrambling a real point demands. It's genuinely useful activity and still clearly more than sitting still, but it's honest to say it burns meaningfully less than either doubles or singles, and treating a relaxed hitting session as equivalent to a real match in a calorie budget will overstate the effort involved.
| Playing Style | MET | Calories/hour | Calories (70 kg, 60 min) | Kilojoules |
|---|---|---|---|---|
| Hitting balls, casual practice, non-game play | 5.0 | 350 kcal/hr | 350 kcal | 1,464 kJ |
| Doubles match | 6.0 | 420 kcal/hr | 420 kcal | 1,757 kJ |
| Singles match | 8.0 | 560 kcal/hr | 560 kcal | 2,343 kJ |
Put another way, for this 70 kg player over a 60-minute session, singles burns exactly 60% more than doubles, and 60% more than casual hitting practice as well — while doubles itself already burns 20% more than casual hitting.
This table holds the format constant at a doubles match (MET 6.0) for a full 60-minute session, so you can see how much body weight alone changes the total.
| Body Weight | MET | Calories (60 min) | Kilojoules |
|---|---|---|---|
| 60 kg | 6.0 | 360 kcal | 1,506 kJ |
| 70 kg | 6.0 | 420 kcal | 1,757 kJ |
| 75 kg | 6.0 | 450 kcal | 1,883 kJ |
| 80 kg | 6.0 | 480 kcal | 2,008 kJ |
| 90 kg | 6.0 | 540 kcal | 2,259 kJ |
| 100 kg | 6.0 | 600 kcal | 2,510 kJ |
Because body weight is a straight multiplier in the formula, a 100 kg player burns two-thirds more than a 60 kg player in the identical doubles match, even though both are covering the same share of the court at the same intensity.
Australian nutrition panels list energy in kilojoules, not calories, so it's worth seeing your session in the same unit your food packaging uses. Multiply your calorie figure by 4.184 to get kilojoules. A 70 kg player's 60-minute singles match burns about 560 kcal, which is roughly 2,343 kJ — useful if you want to weigh your match against the energy value printed on a post-match sports drink or snack.
Why does singles tennis burn more calories than doubles?
In singles you're the only player on your side of the net, so you alone have to cover the full width and depth of the singles court for every point. In doubles, that same coverage responsibility is split between two players, which means more standing and recovering between the shots you personally have to chase. Less ground covered per point, shared across more players, is the most likely explanation for singles' higher MET value of 8.0 compared with doubles' 6.0.
Does a hitting/practice session with a coach count as much as a real match?
Generally no. A coached or casual hitting session often involves balls fed at a controlled pace, pauses to work on technique, and less of the reactive scrambling that a real scored point demands, which is why this calculator uses a lower MET value (5.0) for hitting balls and non-game practice than for either doubles (6.0) or singles (8.0). It's still worthwhile activity, just not the same physical demand as a genuine match.
How does tennis compare to running or cycling for calorie burn?
A singles match's MET of 8.0 sits in a similar range to a solid, sustained running pace, while doubles at MET 6.0 is closer to a brisk cycling pace or a fast walk uphill. Casual hitting practice at MET 5.0 is closer to a moderate walk or an easy cycle. As with any sport, actual effort varies a lot with how hard you personally push yourself during a session, so these are broad comparisons rather than exact equivalents.
Does playing style — baseline rallying vs serve-and-volley — change the number?
Almost certainly yes in practice, but the published MET values used here don't split singles or doubles out by playing style. A serve-and-volley player who's frequently sprinting to the net and covering short, sharp angles likely works somewhat differently than a baseline rallier grinding out long points from the back of the court, even within the same format. Treat the singles or doubles MET value as a reasonable match-level average rather than a style-specific figure.
Does playing position in doubles — net vs baseline — change calorie burn?
It plausibly could, since a net player is often making quick reflex volleys and short lateral movements while a baseline partner covers more ground per shot, but the compendium doesn't publish separate MET values for doubles positions. This calculator applies the one doubles MET value (6.0) regardless of where you typically play, so treat the result as an average across a full doubles match rather than a position-specific figure.
How many calories does a full match burn?
Actual playing time in a match varies enormously with the score, the surface and how long the rallies run, but as a rough guide, a 70 kg player in a singles match with around 90 minutes of genuine playing time (1.5 hours) would burn approximately 8.0 × 70 × 1.5 = 840 kcal, about 3,515 kJ. A three-set match can easily involve well over two hours on court once changeovers and breaks are included, so this figure reflects active playing time rather than total time at the venue.
Does tennis count toward Australian physical activity guidelines?
Yes. Australian guidelines recommend around 150 to 300 minutes of moderate-intensity activity per week, or a shorter amount of vigorous activity. A singles match sits at or above the vigorous-intensity threshold, so a single hour on court can go a meaningful way toward a week's target, while doubles and casual hitting practice both still count as moderate-to-vigorous activity contributing at a somewhat slower rate.
What are the limitations of this calorie estimate?
This calculator uses population-average MET values, not a personalised measurement of your effort. It doesn't account for your fitness level, how much of the session you spent actively rallying versus retrieving balls or resting between points, your playing standard, the court surface, or environmental factors like heat. The three tiers are also broad categories — a highly competitive social hit or a relaxed, low-intensity doubles match could sit between the documented figures. Use the result as a solid planning figure rather than an exact measurement.
