Estimate calories and kilojoules burned painting — painting inside the house, general painting, or painting outside the house — based on your body weight and session duration. House painting is one of the most common DIY and home renovation tasks in Australia, whether it's repainting a single room, wallpapering, or tackling a full exterior repaint, and it involves genuine sustained physical activity: reaching, standing, repetitive arm movement, and occasionally working from a ladder.
House painting calorie burn depends on the type of painting work involved, captured here as three tiers: painting inside the house (MET 3.3), general painting (MET 4.5), and painting outside the house (MET 5.0). The formula is calories = MET × body weight (kg) × duration (hours). A 75 kg person painting for 90 minutes burns 371 kcal (about 1,553 kJ) painting inside the house, 506 kcal (about 2,118 kJ) doing general painting, and 563 kcal (about 2,354 kJ) painting outside the house — noticeably more energy burned outdoors, largely due to the extra reaching, ladder work and larger surface areas involved.
| Painting Type | MET | Calories | Kilojoules |
|---|
The calculation uses a MET (Metabolic Equivalent of Task) value for your specific type of painting work, your body weight, and the duration of your session. This calculator uses three MET tiers taken directly from the Home Repair activity codes in the 2024 Adult Compendium of Physical Activities — painting inside the house (code 06160, "painting inside house, wallpapering, scraping paint", MET 3.3), general painting (code 06165, "painting", MET 4.5), and painting outside the house (code 06150, "painting, outside home", MET 5.0). All three values are literature-supported entries in the Compendium, not estimated figures.
| Painting Type | MET | Calories (75 kg, 90 min) | Kilojoules |
|---|---|---|---|
| Painting inside the house | 3.3 | 371 kcal | 1,553 kJ |
| General painting | 4.5 | 506 kcal | 2,118 kJ |
| Painting outside the house | 5.0 | 563 kcal | 2,354 kJ |
Not all painting work is equally demanding, which is why this calculator uses three separate tiers rather than a single number. Painting inside the house covers interior painting, wallpapering and scraping old paint — mostly arm and shoulder work carried out at a moderate pace, often broken up by cutting-in, taping, moving furniture and letting coats dry. General painting steps up slightly, reflecting a somewhat more sustained moderate pace of painting work overall, without the extra demands of ladder work or awkward exterior surfaces. Painting outside the house is the most demanding tier, and generally involves more reaching, more time spent up and down a ladder, and often larger and more varied surface areas — weatherboards, eaves, fascias, gutters and trim — than a single indoor room.
The gap between the tiers comes down to the physical demands of the work itself, not just the paint going on the wall. Indoor painting and wallpapering tend to happen at a steadier, more contained pace, with plenty of natural pauses for cutting in, taping edges and waiting for coats to dry. Exterior painting more often calls for sustained arm elevation above shoulder height, repeated climbing and repositioning of a ladder, and covering larger, less uniform surfaces in the open air — all of which add up to a higher overall energy cost, reflected in the higher MET value of 5.0 for painting outside the house compared with 3.3 for painting inside.
Painting can genuinely contribute to physical activity, particularly general and outdoor painting, which sit in a similar intensity range to other activities widely recognised as moderate physical activity. Whether a given painting session counts towards a particular physical activity guideline or weekly target depends on the intensity and duration involved, and general population physical activity guidelines are published by the Australian Government Department of Health and by the World Health Organization. This calculator provides a general estimate of energy expenditure only — it isn't personalised health advice, so anyone wanting to know how painting fits into a specific health or fitness plan should refer to official guidelines or speak with a healthcare professional.
A single coat rarely takes long, but a full painting project — prepping, cutting in, rolling, and often a second coat — can easily add up to several hours of work spread across a weekend. At the general painting tier (MET 4.5), a 75 kg person who totals 6 hours of painting across several sessions burns around 2,025 kcal, or roughly 8,473 kJ, in total. Because the effort tends to shift between tiers over a weekend project — some steady interior rolling, some careful cutting-in around trim, perhaps a stretch of exterior work — it's worth running the calculator separately for each block of time at the tier that best matches it, then adding the results together for a more accurate project total.
House painting is a genuinely common DIY project across Australia, whether it's freshening up a single room before selling, repainting a rental between tenants, or tackling a full exterior repaint to protect weatherboards and render from the sun. Australia's climate means exterior painting projects are often possible across much of the year in many parts of the country, and a large share of homeowners and renters take on at least some interior painting themselves rather than hiring a professional for every job. Whether it's a weekend spent rolling a single bedroom or a bigger job involving ladders, scaffolding and an entire facade, painting sits alongside other home-maintenance tasks as a source of genuine, if often overlooked, physical activity.
The table below holds painting type constant at the general painting tier (MET 4.5) 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 |
|---|---|---|---|
| 55 kg | 4.5 | 248 kcal | 1,036 kJ |
| 65 kg | 4.5 | 293 kcal | 1,224 kJ |
| 70 kg | 4.5 | 315 kcal | 1,318 kJ |
| 75 kg | 4.5 | 338 kcal | 1,412 kJ |
| 85 kg | 4.5 | 383 kcal | 1,600 kJ |
| 95 kg | 4.5 | 428 kcal | 1,789 kJ |
Here body weight is fixed at 75 kg while both session length and painting type change, so you can compare how much a more demanding tier and a longer session each add to the total.
| Duration | Inside (MET 3.3) | General (MET 4.5) | Outside (MET 5.0) |
|---|---|---|---|
| 30 minutes | 124 kcal / 518 kJ | 169 kcal / 706 kJ | 188 kcal / 785 kJ |
| 60 minutes | 248 kcal / 1,036 kJ | 338 kcal / 1,412 kJ | 375 kcal / 1,569 kJ |
| 90 minutes | 371 kcal / 1,553 kJ | 506 kcal / 2,118 kJ | 563 kcal / 2,354 kJ |
Australian nutrition panels list energy in kilojoules, not calories, so it's worth converting your session into the same unit your food packaging uses. Multiply your calorie figure by 4.184 to get kilojoules. A 75 kg person doing general painting for 60 minutes burns about 338 kcal, which is roughly 1,412 kJ — a useful figure to weigh up against the energy value printed on a post-painting snack or drink.
How many calories does painting burn?
It depends on the type of painting work. A 75 kg person painting for 90 minutes burns around 371 kcal painting inside the house (MET 3.3), around 506 kcal doing general painting (MET 4.5), and around 563 kcal painting outside the house (MET 5.0). Lighter or heavier people, and longer or shorter sessions, will see proportionally lower or higher numbers, so use the calculator above with your own weight and duration for a personalised estimate.
Why does painting outside burn more calories than painting inside?
Painting outside the house typically involves more reaching, more time spent on ladders, and often larger and more varied surface areas — weatherboards, eaves, fascia and trim — than painting a single room indoors. Indoor painting and wallpapering tend to be done at a steadier, more contained pace with more natural breaks, while exterior painting more often calls for sustained arm elevation, balance and repositioning of ladders, which is why it carries a higher MET value (5.0) than painting inside the house (MET 3.3) or general painting (4.5).
Does painting count as exercise?
Painting can genuinely contribute to physical activity, particularly general and outdoor painting, which sit in a similar intensity range to other activities considered moderate physical activity. Whether a specific painting session counts towards a particular physical activity guideline or weekly target depends on the intensity and duration involved, and general population guidelines are published by the Australian Government Department of Health and by the World Health Organization. This calculator provides a general estimate of energy expenditure only — it isn't personalised health advice.
How many calories would a full weekend painting project burn?
It adds up quickly once you total the hours. At the general painting tier (MET 4.5), a 75 kg person painting for 6 hours across a weekend — say, several sessions of prepping, cutting in and rolling — burns around 2,025 kcal (about 8,473 kJ) in total. Longer projects, heavier painters, or more time spent on the exterior tier will push that figure higher, so it's worth running the calculator separately for each session and adding the results together for an accurate project total.
What's the difference between the three painting tiers on this calculator?
Painting inside the house (MET 3.3) covers interior painting, wallpapering and scraping old paint, typically done at a moderate pace with regular breaks. General painting (MET 4.5) covers a slightly more sustained moderate pace of painting work. Painting outside the house (MET 5.0) is the most demanding tier, reflecting the extra reaching, ladder work and often larger surface areas involved in exterior jobs. Choosing the tier that best matches what you actually did gives a more accurate estimate than treating all painting as the same activity.
Are there safety tips for ladder work and extended reaching while painting?
Yes — ladder work and extended overhead reaching are worth taking seriously, separate from the calorie burn. Use a stable, properly positioned ladder on level ground, avoid overreaching sideways, and move the ladder rather than stretching further than is comfortable. Take regular breaks during extended overhead or reaching work to rest your arms and shoulders, wear appropriate footwear, and have someone else around when working at height where practical. This is general commonsense guidance, not medical or trade safety advice — for structured guidance, refer to official workplace or ladder safety resources.
Does body weight change how many calories painting burns?
Yes. Because calories equal MET multiplied by body weight in kilograms multiplied by duration in hours, body weight is a direct multiplier in the formula. At the general painting tier for a 60-minute session, an 85 kg person burns roughly 383 kcal compared with about 248 kcal for a 55 kg person completing the identical session at the identical pace.
How do I convert calories burned painting into kilojoules?
Multiply the calorie figure by 4.184, the standard conversion between kilocalories and kilojoules used on Australian food labels. A 75 kg person doing general painting for 60 minutes burns about 338 kcal, which converts to roughly 1,412 kJ — a useful number to weigh against the energy value on a post-painting snack or drink.
