Screen Break Frequency Calculator

Work out screen break frequency instantly with clear inputs, formula shown and shareable results.

About Screen Break Frequency Calculator

Display screen guidance favours short frequent breaks over long infrequent ones: roughly five to ten minutes away from the screen after every fifty minutes of continuous work. Breaks are most effective before fatigue sets in, and changing activity counts as a break provided it does not involve the screen.

Formulas

Break count

Breaks = floor(total screen minutes / (interval + break length))

Break share

Share = total break minutes / total working minutes

Worked example

With the default values below, Screen Break Frequency Calculator returns Breaks required per day of 8. Change any input above and every figure here is recalculated in your browser.

Inputs used

Screen work per dayaccepts 0.5–16 h: 8 h
Maximum continuous screen timeminimum 5 min: 50 min
Break lengthminimum 1 min: 5 min
Current longest continuous spellminimum 1 min: 120 min

Results

Breaks required per day: 8
Total break time per day: 40 min
Break time as share of the day: 8.33% %
Current practice assessment: Continuous screen time is too long — introduce short frequent breaks

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
Preliminary estimate only. Display screen equipment work patterns should follow the applicable regulations and individual assessment.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is the Screen Break Frequency figure worked out?

Breaks = floor(total screen minutes / (interval + break length)). Display screen guidance favours short frequent breaks over long infrequent ones: roughly five to ten minutes away from the screen after every fifty minutes of continuous work.

Do breaks have to be away from the desk?

Not necessarily, but they must be away from the screen. Filing, a phone call or a task requiring distance focus all give the eyes and posture the change they need.

What values do I need to enter?

This calculator takes 4 inputs: Screen work per day, Maximum continuous screen time, Break length, Current longest continuous spell. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
