Screen Time by Age: Where the Guidelines Stop and the Household Plan Starts

The question tends to arrive in the second week of the summer holidays, somewhere between the third episode of the same show and the sound of an argument starting in the next room. How much screen time is too much? You look it up, find a number, and feel no better. The number is the easy part. On its own, it is also the least useful part.

What the guidelines give you is a ceiling, and a direction. Wherever a number is set, the same line follows: less is better. That line rarely makes it into the summaries. This guide sets out the bands as they are written, explains the difference between the two kinds of limit that get flattened into one, and then turns the guidance into a household plan you can write on one page and put on the fridge.

Our verdict is straightforward. Treat the age limits as a ceiling, not a target. Protect sleep and movement first, then set the screen window, and write the agreement down together. The plan will not stop every argument. It gives everyone the same reference point when an afternoon goes sideways.

What the guidelines set

The national guidance comes from the Australian 24-hour movement guidelines, which cover physical activity, sleep and screen time across the same day. NSW Health’s Sydney Children’s Hospitals Network reproduces the screen time bands, and the NSW Government sets out the practical rules around them. The wording is worth reading closely, because the qualifiers do most of the work.

The first distinction is the one that gets flattened. For children aged two to five, the limit is one hour of sedentary screen time a day. Unlike the older band, it is not limited to recreational use: the television after breakfast, the tablet in the pram, the phone handed over at a cafe, all the sitting-still screen time sits inside that hour.

For children aged five to seventeen, the limit changes shape. It is two hours of sedentary recreational screen time a day, and required schoolwork does not count towards it. Sedentary is doing real work in that sentence too. A screen used while a child walks around the house, or as part of a game that keeps them moving, is not the same thing as two hours on a couch.

The second distinction is the line that follows every number: less is better. That is not a slogan. It tells you the figure is the edge of the guidance, not a daily target to reach. A day with less screen time is a better day by the guidelines’ own logic, even when the difference is small.

Sleep and movement sit in the same 24 hours. The guidelines treat them together because they compete for the same day. An hour of screen time is also an hour not spent asleep or moving, and the guidance is asking families to see that trade rather than the screen alone.

Where the numbers stop

A ceiling does not tell you what is on the screen. It does not tell you who is in the room, whether the content is being discussed, or what the screen replaced. Those questions decide whether an hour was fine. No national figure can answer them for your household.

Take two hours. One child watches a film with a parent who pauses it to talk about what is happening. Another scrolls short videos alone in a bedroom with the door closed. Both use two hours. The guideline sees the same number. You see two different afternoons.

This is where guilt usually starts. A number is easy to measure and easy to fail, so it becomes the thing parents argue about. The more useful question is simpler: what did the screen push out today? If nothing important moved, the day was probably fine. If sleep, dinner, a conversation or an afternoon outside went missing, that is the part to fix first.

There is a stricter reading of all this, and it deserves a fair hearing. For children under two, the guidance is no sedentary screen time at all. That is not a number to negotiate down. It is a clear line, and the families who hold it are following the evidence as written. The harder part to act on is that a parent’s own phone use sets the tone in a room long before any rule does.

Protect sleep first

If the household plan has one anchor, make it sleep. The guidance is direct: stop screen use before bedtime, keep screens out of bedrooms, and set screen-free times such as meals. The NSW Government’s advice is to set rules and routines rather than improvise them each night.

The reason is practical. A screen before bed can delay the point where a child settles, and a device in the bedroom keeps the option open all night. Moving the charger to the kitchen is a small change with an outsized effect, because it removes the decision from the tired version of everyone in the house.

The second half of the sleep anchor is an internet-off time. Health and Wellbeing Queensland suggests turning off the home internet at a set time. It works best when the rule applies to adults too. A child who is told to put the phone away while a parent keeps scrolling has learned something different from the words.

Sleep is also the first thing to wobble when the clocks change. If the routine is still out of step after the shift into daylight saving, this guide to daylight saving and family sleep is a useful place to reset it.

None of this needs a product. A charger in the kitchen, a set time for the router, and one agreed bedtime routine cover most of it.

Then movement

Once sleep is anchored, the second rule is a daily outside block. The guidance notes that children who spend more time on screens tend to be less physically active across the day. That is a tendency, not a rule, but it points the same way. Less screen time is better for movement, and movement is easier to protect when it has a fixed place in the day.

The outside block does not have to be sport. A walk to the shop, a bike ride, a turn around the block with the dog, kicking a ball against a wall. The point is to get the body moving before the screen window opens, not after. A screen is very good at swallowing the part of the afternoon that was going to be used for something else.

Long sitting is worth breaking up too. The guidelines sit inside a 24-hour day for a reason: the goal is not a perfect hour of exercise, it is a day that includes movement in ordinary ways. A family walk after dinner counts. So does gardening, or walking to school.

The same applies on a wet day. Movement can happen inside. A hallway obstacle course, a dance song, a trip up and down the stairs with the washing. The weather changes the plan. It does not have to cancel the principle.

The household plan

Here is what the guidance looks like when it is written down. Take a hypothetical household with two children, one aged seven and one aged thirteen, in the first week of January. The plan is one page, not an app, and it starts with sleep and movement because those anchors make the screen rules easier to keep.

The seven-year-old is on holidays and has no schoolwork to protect. The thirteen-year-old is old enough to manage a window with a check-in rather than a countdown. The plan below is a worked example, not a template to copy exactly. The point is the shape: anchors first, then windows, then the rules about where devices live.

The two hours for the thirteen-year-old is the recreational ceiling, not a target. If the day fills up and the window shrinks, the plan is working. If the window is used every single day and sleep is slipping, the review is the place to change it, not a confrontation at nine at night.

The plan also needs a line that is easy to forget: the parent’s phone rule. A family agreement that only binds the children is a rule, not an agreement. Health and Wellbeing Queensland’s framing is useful here: rules, expectations and consequences, agreed together, with devices kept in an easily supervised shared space.

One more thing belongs on the page: the review date. Two weeks is long enough to see what is realistic and short enough that nobody has to live with a bad rule for a whole summer.

When the plan fails

It will fail. A sick day, a wet week, a work deadline that lands in the middle of the holidays. The plan should have a fallback written in, so the exception does not become a negotiation every time. On a sick day the screen window can stretch. In a wet week the movement block moves indoors. A deadline week might mean more television and less outside, and that is a trade a family can make on purpose.

The under-two line does not move for any of those reasons. For a child under two, the guidance remains no sedentary screen time. A sick day does not rewrite it.

You do not need to feel guilty about using the fallback. The plan is a set of defaults, not a scorecard. The only failure that matters is a plan nobody can remember by February.

If the pattern is not a wet day or a bad week, but a child who is refusing to leave the house for school, treat it as a different problem. A calm guide to school refusal is the better place to start than another screen rule.

Teens and independence

The five to seventeen band covers thirteen ages, which is one reason it causes so much argument. A five-year-old and a sixteen-year-old are not the same problem, and the guidance does not pretend they are.

For teenagers, the useful shift is from enforcement to agreement. The parents who argue for autonomy by sixteen or seventeen usually do so on a condition: school and sleep are holding. That is a reasonable test. Self-regulation is a skill, and a skill needs practice, including the practice of getting it wrong.

The wider set of life skills worth teaching before adulthood is a useful companion to that idea. A teenager who can plan a day, keep a commitment and notice when they are tired is better equipped than one who has simply been told the number.

The plan should change as the child does. A rule that made sense at eight can be an insult at fifteen. Rewriting it together is part of the point.

The Plan Outlasts the Holidays

The number is the easy part. The plan is the part that lasts. Start with sleep, add movement, then set the screen window around the day that works for your family. Write it down, agree the fallback, and book the two-week review before the holidays run away with you.

The national guidance says less is better. It says it wherever a number is set, and it says it for a reason. A household plan is how a family gets to less without turning every afternoon into a fight. The ceiling is where the guidelines stop. The plan is where your household starts.
