The tennis calorie calculator estimates calories burned based on your body weight, session duration, activity intensity, and court surface. MET (Metabolic Equivalent of Task) values from exercise science research give accurate results for singles, doubles, drills, and machine practice. A 70 kg player burns 400–560 kcal per hour depending on match intensity.

How to Use the Tennis Calorie Calculator
This tennis calorie calculator uses MET (Metabolic Equivalent of Task) values from ACSM exercise science research to give accurate calorie burn estimates for every type of tennis session. Enter your body weight, session length, activity type, and court surface to see total calories burned with a full session breakdown.
Step 1: Enter Your Body Weight
Body weight is the biggest driver of calorie burn — heavier players burn significantly more calories per hour. A 90 kg player burns about 29% more than a 70 kg player at the same intensity. Use the unit toggle to switch between kg and lbs. The default 70 kg represents an average adult player.
Step 2: Select Activity Type and Surface
Activity type determines the MET value: competitive singles (MET 8.0) burns nearly twice as much as recreational doubles (MET 5.0). Court surface adds a smaller modifier — clay slows the ball, requiring more effort (+5%), while grass is faster and slightly less taxing (-3%). Most recreational players on hard courts should use the default settings.
MET Values for Different Tennis Activities
MET (Metabolic Equivalent of Task) measures exercise intensity relative to rest. A MET of 1.0 equals resting metabolism. Here are the MET values and calorie burn estimates for each tennis activity type for a 155 lb (70 kg) player:
| Activity | MET | Cal / 30 min (155 lb) | Cal / 60 min (155 lb) |
|---|---|---|---|
| Singles competitive/tournament | 8.0 | 280 | 560 |
| Singles moderate/recreational | 7.3 | 256 | 511 |
| Doubles competitive | 6.5 | 228 | 455 |
| Doubles recreational | 5.0 | 175 | 350 |
| Drills / groundstroke practice | 5.5 | 193 | 385 |
| Ball machine / hitting practice | 4.5 | 158 | 315 |
Calorie formula: MET × body weight in kg × duration in hours = calories burned. For a 80 kg player doing 90 minutes of competitive singles: 8.0 × 80 × 1.5 = 960 kcal.
Step 3: Read the Session Breakdown
The session breakdown splits calories across active play, rest/changeovers, warmup, and cooldown. In competitive singles, only about 35% of session time involves active rallying — the rest is walking, waiting, and bouncing. In drills or ball machine sessions, active time rises to 50–55%, explaining why focused practice can burn more calories than casual match play.
How Tennis Compares to Other Sports
Tennis ranks as a moderate-to-high intensity cardio workout, sitting between running pace groups in terms of calorie burn. Here is how competitive singles (MET 8.0) compares to common cardio activities for the same 70 kg player in a 60-minute session:
- Running at 6 mph: MET 9.8 — burns 686 kcal/hr, about 22% more than tennis singles
- Cycling at 12–14 mph: MET 8.0 — burns 560 kcal/hr, same as competitive tennis singles
- Swimming freestyle (moderate): MET 8.0 — burns 560 kcal/hr, identical to tennis singles
- Competitive tennis singles: MET 8.0 — burns 560 kcal/hr
- Basketball (game play): MET 6.5 — burns 455 kcal/hr
- Recreational doubles tennis: MET 5.0 — burns 350 kcal/hr
- Walking briskly at 3.5 mph: MET 4.3 — burns 301 kcal/hr
A key difference is the interval structure. Unlike running or cycling (steady-state cardio), tennis involves explosive 3–10 second sprints followed by 15–25 seconds of rest between points. This HIIT-like pattern burns fat at a higher rate per calorie than steady-state exercise and improves cardiovascular adaptability over time.
Heart Rate Zones During Tennis
During a competitive singles match, heart rate fluctuates significantly between points. Active rallying pushes heart rate to 85–95% of max heart rate (anaerobic threshold zone), while changeovers and between-point rest bring it back to 55–65%. This natural HIIT pattern — alternating high-intensity bursts with active rest — is one reason tennis provides excellent cardiovascular conditioning despite the total session MET being lower than steady-state running.
For weight loss and cardiovascular fitness, the interval nature of tennis is a significant advantage: the post-exercise oxygen consumption (EPOC or "afterburn") is higher after HIIT-style exercise than after steady-state cardio at the same total calorie expenditure. A 60-minute competitive singles session continues to burn elevated calories for 24–48 hours after play.
MET Values Used in This Calculator
Singles competitive/tournament: MET 8.0. Singles moderate/recreational: MET 7.3. Doubles competitive: MET 6.5. Doubles recreational: MET 5.0. Drills/groundstroke practice: MET 5.5. Ball machine practice: MET 4.5. These values come from the Compendium of Physical Activities and align with ACSM guidelines.
How Tennis Compares to Other Racket Sports
Squash (MET 12.0) burns the most calories of any racket sport due to the confined court and continuous explosive movement. Racquetball (MET 10.0) is next. Competitive tennis (MET 8.0) sits mid-range, burning roughly 560 kcal/hr for a 70 kg player. Pickleball (MET 5.5) and table tennis (MET 4.0) are the least demanding. The comparison chart shows exact calorie totals for your specific session length.
FAQ
Is this tennis calorie calculator free?
Yes, completely free with no signup required.
How many calories do you burn playing tennis?
A 155-pound person burns approximately 400–500 calories per hour playing singles tennis and 300–400 calories in doubles. Competitive matches burn more than practice. A typical 1-hour singles match burns 350–500 calories depending on intensity and body weight.
Is tennis good for weight loss?
Yes — tennis combines cardio, agility, and strength. The stop-and-start movement pattern is highly metabolic. Playing 3–4 times per week provides significant calorie deficit and cardiovascular fitness improvement.
Does doubles tennis burn as many calories as singles?
Doubles burns approximately 20–25% fewer calories than singles because court coverage is shared and rallies tend to be shorter. However, doubles at competitive level can match singles intensity.
How does tennis compare to other sports for calorie burn?
Tennis burns roughly 400–600 cal/hr (singles), similar to running at 5 mph (493 cal/hr) or cycling at 12–14 mph (480 cal/hr). The irregular sprinting pattern makes tennis excellent for cardiovascular health and metabolic fitness.
How many calories does an hour of tennis singles burn?
Competitive singles burns approximately 560 kcal/hr for a 70 kg (155 lb) player. For a 90 kg (198 lb) player, that rises to 720 kcal/hr. Recreational singles at MET 7.3 burns 511 kcal/hr for a 70 kg player. Body weight is the primary variable — heavier players burn proportionally more calories per session.
Is tennis better exercise than running?
Competitive tennis (MET 8.0) burns slightly fewer calories than running at 6 mph (MET 9.8), but tennis provides HIIT-style intervals that improve cardiovascular fitness and fat burning more effectively than steady-state running at the same total calorie output. Tennis also develops agility, reaction time, and upper-body strength that running does not.
What MET value does tennis have?
Tennis MET values vary by format: competitive singles = MET 8.0, moderate/recreational singles = MET 7.3, competitive doubles = MET 6.5, recreational doubles = MET 5.0, drills/practice = MET 5.5, ball machine hitting = MET 4.5. Court surface also affects the effective MET — clay adds about 5% effort, grass reduces it by about 3%.
