Screen Time Calculator

Screen time here is hours on phones, laptops, TVs or consoles compared with the hours you are awake. The result is a percentage and the hours left off-screen. It does not say a healthy limit for you or for a child. It is a diary check, not a diagnosis.

What is this calculator?

Screen time here is hours on phones, laptops, TVs or consoles compared with the hours you are awake. The result is a percentage and the hours left off-screen. It does not say a healthy limit for you or for a child. It is a diary check, not a diagnosis.

How it works

Common questions

What is the screen time calculator?

It shows what share of your waking day is on a screen. It cannot see apps and it is not medical advice.

Does work laptop time count?

Only if you include it. Many people log a work total and a leisure total separately.

Is there an official adult limit?

Not a single NHS hour cap for adults. Sleep, sitting and outdoor time often matter more than one magic number.

What about children?

This page is a time share, not a child guideline. The sitting time and sleep calculators sit nearby if evenings are the problem.

Example scenarios

Rohan, hybrid desk day

6 screen hours, 16 hours awake

38 percent of the waking day. About 10 hours off-screen.

Caitlin, phone in bed after shifts

9 screen hours, 16 hours awake

56 percent of the waking day. About 7 hours off-screen.

Yusuf, revision week with a shorter day

4 screen hours, 15 hours awake

27 percent of the waking day. About 11 hours off-screen.

Understanding your results

A high percent is a prompt to move one block, not a verdict. Pair it with the sitting time calculator if the day is chair-shaped, or the sleep calculator if screens run late.
