Presentation Duration
Time a slide deck from slide count, minutes and notes.
About Presentation Duration
Multiplying the slide count by the time per slide estimates the deck's running length, with the word load timed separately. Presenters often overrun because they ignore per-slide time; this check catches length before the rehearsal does.
Formula
Presentation Duration
Total = slides x minutes per slide
- minutes per slide
- Average time spent on each slide during delivery

Assumptions and limits
- The result is derived only from the 3 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 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
