Calories Burned Playing tennis singles at 85 kg — 680 kcal per Hour
Playing tennis singles at 85 kg (176-198 lb) burns about 680 kcal per hour. That figure comes from the activity's MET value of 8.0 in the 2011 Compendium of Physical Activities, multiplied by body weight: 8.0 × 85 kg × 1 hour = 680 kcal. This page works the numbers out in full — for 15, 30, 45, 60 and 90 minutes, across all four weight bands, and against four comparable activities at the same weight — so you can plan sessions with real figures instead of guessing.
Tennis singles means one player against one, covering the whole court alone — sprinting to wide balls, recovering to the centre, serving, volleying and chasing drop shots. There is nowhere to hide: every ball is yours, and the rallies are longer and the running heavier than in doubles. The Compendium gives it 8.0 METs, a vigorous figure in the same band as a basketball game or a fast swim.
At 85 kg that means 680 kcal per hour — a strong return for a sport that most people play for fun rather than fitness. It is also a sport that rewards longevity: players in their sixties and seventies play competitive singles, because the game scales to your speed and the rallies adapt to your level. The calorie figure is only part of the story, but it is a good part.
Calculate your own numbers
Use the Calorie calculator to work out your own burn for playing tennis singles at your exact weight and session length. Enter your weight, pick the activity and set the duration, and the tool applies the same MET formula shown below. You can also try the running calorie calculator to see how this session fits into your total daily energy use.

The formula, shown and cited
The standard way to estimate the energy cost of an activity is the MET formula from the Compendium of Physical Activities (Ainsworth et al., Medicine & Science in Sports & Exercise, 2011; 43(8): 1575–1581):
Calories (kcal) = MET × body weight (kg) × duration (hours)
One MET is the energy you use sitting quietly at rest — about 1 kcal per kilogram of body weight per hour. An activity rated at 8.0 METs therefore uses 8.0 times as much energy as resting. The Compendium's MET values come from published studies that measured oxygen use during each activity, so they are measured averages, not guesses. The value used here is the one recorded for this activity in the FitCalc activity data, taken from the Compendium.
Worked through for this page:
- MET for playing tennis singles: 8.0
- Body weight: 85 kg (the midpoint of the 80-90 kg band, 176-198 lb)
- Duration: 1 hour
- Calculation: 8.0 × 85 × 1 = 680 kcal
For a 30-minute session the same calculation is 8.0 × 85 × 0.5 = 340 kcal. Nothing else is hidden in the maths — if your weight or duration changes, only those two numbers change.
Your numbers at 85 kg
| Duration | Calculation | Calories burned |
|---|---|---|
| 15 minutes | 8.0 × 85 × 0.25 | 170 kcal |
| 30 minutes | 8.0 × 85 × 0.5 | 340 kcal |
| 45 minutes | 8.0 × 85 × 0.75 | 510 kcal |
| 60 minutes | 8.0 × 85 × 1 | 680 kcal |
| 90 minutes | 8.0 × 85 × 1.5 | 1020 kcal |
That is about 11.3 kcal per minute of playing tennis singles at this weight. A short session still counts: even 15 minutes burns 170 kcal, and three 15-minute sessions across a day add up to the same 510 kcal as one 45-minute session.
How the burn changes with body weight
The MET value stays the same — it describes the activity, not the person — but the calorie total scales with weight, because a heavier body costs more energy to move:
| Body weight | Calories per hour | Calories per 30 minutes |
|---|---|---|
| 55 kg | 440 kcal | 220 kcal |
| 65 kg | 520 kcal | 260 kcal |
| 75 kg | 600 kcal | 300 kcal |
| 85 kg | 680 kcal | 340 kcal |
Two people doing the same activity for the same time can therefore burn quite different amounts, and that is expected — it is physics, not a mistake in the formula. If your weight sits between two rows, your figure sits between the two values.
How playing tennis singles compares
Here is playing tennis singles against four other activities at the same 85 kg, all using the same MET formula:
| Activity | MET | Calories per hour at 85 kg |
|---|---|---|
| Playing tennis singles | 8.0 | 680 kcal |
| Playing a basketball game | 8.0 | 680 kcal |
| Playing handball | 8.0 | 680 kcal |
| Rock climbing | 8.0 | 680 kcal |
| Swimming backstroke | 7.0 | 595 kcal |
Use this table to choose, not to judge. A higher number means a harder session, not a better one: the activity you enjoy and repeat three times a week beats the activity that burns more per hour but that you quit after a fortnight. Mixing intensities across the week — one harder session, two easier ones — is usually more sustainable than doing the hardest activity every time.
Fitting playing tennis singles into your week
| Sessions per week | 30 minutes each | 60 minutes each |
|---|---|---|
| 2 sessions | 680 kcal | 1360 kcal |
| 3 sessions | 1020 kcal | 2040 kcal |
| 5 sessions | 1700 kcal | 3400 kcal |
A singles match usually lasts 60 to 90 minutes: best-of-three sets, with short changeovers every two games and a constant rally rhythm. At 8.0 METs, playing tennis singles counts as vigorous activity, so it contributes directly towards the widely used target of 150 minutes of moderate activity a week for adults. To burn 500 kcal from playing tennis singles alone takes about 44 minutes at 85 kg, and 1,000 kcal takes about 88 minutes — spread across the week, that is far more realistic than trying to do it in one session. Build up gradually — add 10% to your weekly total at most, and keep at least one rest day.
How to use the result
What changes the burn for playing tennis singles in practice:
- Rally length: long baseline rallies cost far more than serve-dominated games with short points, and the standard of both players decides which you get.
- Court surface: clay slows the ball and lengthens rallies, which raises the burn, while grass keeps points short.
- Your movement: players who split-step and recover properly work harder — and play better — than players who stand flat-footed.
- Match length and heat: a three-set match in summer sun costs far more than an hour of gentle hitting, and hydration becomes the limiting factor.
Practical tips for this activity:
- Warm up with ten minutes of gentle rallying before playing points — cold legs and a first-serve sprint are a recipe for a calf strain.
- Wear proper tennis shoes with lateral support; running shoes roll on the hard stops and turns that tennis demands.
- Practise the split-step: it is the single movement that most improves both your game and your workout.
- Drink at every changeover: an hour of singles at 85 kg burns about 680 kcal, and summer matches can cost a litre of sweat or more.
Use the numbers on this page to set realistic expectations rather than to chase a daily total. If you are tracking food as well, add the session's calories to your total daily energy expenditure for that day, and remember that the figure is an estimate with roughly 10–20% uncertainty. Do not eat back every calorie the calculator shows: activity trackers and MET estimates both tend to overstate slightly, and a small margin keeps a weight-loss plan on track. If you are aiming to lose weight, keep the deficit modest — 300–500 kcal a day is a common, sustainable range — and keep your total intake above the safety floors of 1,200 kcal a day for women and 1,500 kcal a day for men unless a healthcare professional advises otherwise.
A note at 85 kg
At 85 kg you sit in the heaviest weight band on this site, and your hour costs the most of any band — 680 kcal, against 440 kcal at 55 kg for the same activity and the same duration. That is the largest absolute return on the site, and it is a real advantage if you are using activity to support weight loss. It comes with the clearest trade-off of any band, though: the load on knees, ankles, hips and the lower back is also the highest, and it rises fastest in activities with impact, jumping or rapid direction changes. Start with shorter sessions — 30 minutes rather than 60 — and add time in ten-minute steps over several weeks, keep at least one rest day between hard sessions, and choose lower-impact versions of the activity while your fitness builds. Good footwear is not optional at this weight. The burn is the highest on the page, but the sustainable routine is the one that keeps you moving next month, not the one that burns the most this week.
What the number does NOT tell you
The MET formula is honest about what it measures and silent about the rest. It does not account for your fitness level: a fit person burns fewer calories doing the same activity than an unfit person, because their body is more efficient. It does not account for body composition — two people at 85 kg with different amounts of muscle and fat will burn slightly different amounts. It does not include the afterburn (excess post-exercise oxygen consumption) that follows hard sessions, it does not measure strength, flexibility or balance gained, and it says nothing about how the activity affects your appetite, sleep or mood. Tennis singles at 8.0 METs assumes a real match with sustained rallies, and it varies more than most figures here: a serve-dominated match between big servers burns less, while a grinding baseline match burns more. The estimate also ignores the one-sided load — tennis is famously asymmetrical, loading the serving arm and the dominant leg — and the injury risk to the shoulder, elbow and knees. Tennis elbow, in particular, comes from technique and equipment as much as from effort, and no calorie figure warns you about it. Use the calorie figure as a planning estimate, and judge the activity by how you feel doing it and whether you keep doing it.
Frequently asked questions
How many calories do I burn doing playing tennis singles for 30 minutes at 85 kg?
About 340 kcal. The maths is 8.0 METs × 85 kg × 0.5 hours = 340 kcal. That is an estimate from the Compendium average — your real burn depends on your fitness, your pace and the conditions. If you weigh more or less than 85 kg, use the weight table above to read your own figure.
Is playing tennis singles good for weight loss?
It can help, but only as part of an overall calorie deficit. At 85 kg, an hour of playing tennis singles burns about 680 kcal, which is a useful contribution — roughly the energy in a modest meal — but weight loss still comes from the total balance of food and activity across the week, not from one session. Aim for a gradual loss of 0.5–1% of body weight per week, and never drop below 1,200 kcal a day (women) or 1,500 kcal a day (men) without medical supervision.
How does playing tennis singles compare with playing a basketball game?
At 85 kg, playing tennis singles burns about 680 kcal per hour against 680 kcal for playing a basketball game. If the number is higher, playing tennis singles is the more intense activity; if it is lower, playing a basketball game burns more. The best choice is usually the one you will actually do several times a week — consistency matters more than a small difference in the hourly rate.
Does the calorie burn change if I weigh more or less than 85 kg?
Yes, directly. Calories = MET × weight in kg × hours, so the burn scales with body weight. At 85 kg the same hour of playing tennis singles burns about 680 kcal; at 85 kg it burns about 680 kcal. The MET value itself does not change with weight — it describes the intensity of the activity.
Does tennis singles burn more than doubles?
Yes, substantially. Singles is 8.0 METs — about 680 kcal per hour at 85 kg — while doubles is 4.5 METs, about 382 kcal per hour, because each doubles player covers half the court and rests between points more. Singles is the better workout; doubles is the more social game, and many players choose doubles precisely because it is gentler on the knees.
Estimates only, not medical advice. Minimum safe intakes: 1,200 kcal/day women, 1,500 kcal/day men — consult a healthcare professional before a very-low-calorie diet.
