Screen time: the total is the wrong number to argue about
Two hours of building something and two hours of an autoplaying feed are the same number and not the same thing. Most household arguments about screen time are arguments about the wrong measurement.
Parents arrive at this subject looking for a figure: how many hours is acceptable at nine, at thirteen. The honest answer is that the figure matters much less than what the time displaces and what kind of time it is, which is more useful and considerably less satisfying.
Four kinds of time that get counted as one
Creating: building, drawing, writing, making a video, learning something with a purpose. Connecting: a call with a friend, a co-operative game with people they know. Consuming with intent: a film, a series, a video they chose. And consuming without end: a feed that refills itself and has no natural stopping point.
Only the fourth reliably causes the trouble parents are worried about, and it is the one a daily total treats identically to the first. Counting kinds instead of hours changes what the argument is about.
What it displaces is the actual measure
Sleep first, by a wide margin: a phone in the bedroom costs sleep, and lost sleep is what shows up as mood, concentration and school. Then physical movement, then time with people in the room.
So the boundaries with the highest return are not caps on hours but rules about place and time: the phone charges in the kitchen, screens are off at the table, and the console does not run before the day’s obligations. Those are two of the ten house rules, and they do more than any allowance.
The rules that surround those boundaries, and the argument for agreeing them instead of imposing them, are on the page for parents.
Agreeing it rather than imposing it
A limit a child helped set is a limit that survives contact with a Saturday. The workable structure is a short written agreement: what times are screen-free, what the daily rough shape is, what happens when there is a good reason to exceed it, and what applies to the adults.
The last clause is the one that gives the document its authority. An agreement that binds only the children is a rule with a different name, and everyone in the house can see that.
Where the technical limits belong
Use per-app limits instead of device totals wherever the platform allows, and put the always-allowed list to work: calls, messages, the school apps. A bedtime schedule that also blocks the ability to phone you is a badly configured schedule.
Every platform’s exact path is on the setup guides. The one setting worth applying everywhere is the overnight one, because sleep is the thing with the clearest evidence behind it.
Rough shapes by age
Under five: short, shared, and nothing alone in a room. The content matters more than the clock at that age.
Five to twelve: a predictable daily shape, not a negotiated total, screens out of bedrooms, and per-app limits on the one thing that never ends. This is the band where routine does almost all the work.
Thirteen and up: the total becomes largely unenforceable and the overnight rule becomes the one to hold. Expect to trade: more autonomy over the day in exchange for the phone genuinely leaving the bedroom.
The Saturday problem
Most agreements are written for a Tuesday and then break on the first wet Saturday, a holiday or an illness. If the document has no provision for those, the first exception becomes evidence that the whole thing is negotiable.
So write the exception in from the start: name the days that work differently and say roughly how. A rule that anticipates the weekend keeps its authority on Monday, and it removes the weekly argument about whether today counts.
The same applies to travel, to a sibling’s birthday party and to the week a child is unwell. Predictable exceptions are the opposite of a loophole; they are what stops the agreement being renegotiated from scratch every few days.
What to do
- Count kinds of time, not just hours.
- Take the phone out of the bedroom overnight, the highest-return rule there is.
- Write a short agreement that binds the adults too.
- Use per-app limits, not device totals, and set an always-allowed list.
- Apply the overnight schedule on every device that has one.
- Agree in advance what a good reason to exceed the limit looks like.
Questions about screen time
Is there a recommended number of hours?
Various bodies publish figures and they disagree, largely because the totals hide the differences that matter. A predictable routine, protected sleep and limits on the endless kind of time will get you further than any number.
My child says their friends have no limits.
Possibly true and not the point worth arguing. The negotiable part is the daily shape; the non-negotiable part is sleep, and that framing tends to end the comparison faster than a debate about other households.
Do screen-time limits work on teenagers?
Totals mostly do not. Place-and-time rules and the overnight charge do, because they are observable and do not depend on a counter nobody trusts.
What about homework on a screen?
Put the school apps on the always-allowed list so a schedule never blocks them, and count them separately. Lumping homework into an entertainment allowance is how an agreement loses credibility in a week.
Is the calculator on this site a real answer?
It gives an age-based starting point and then builds the agreement, which is the part that matters. The number is a conversation opener, not a verdict. It is on the toolkit page.
Should adults follow the same rules?
On place and time, yes, and it is the difference between a house rule and an instruction. Children notice the asymmetry long before they mention it.
