Presentation Slides
Estimate talking time and slide count from words per slide.
About Presentation Slides
Multiplying slides by their word density gives the total script, which a deliberate 130-words-per-minute pace converts to minutes. Dividing back reveals how long to spend on each slide. Speakers who plan words instead of slide count avoid cramming or racing, and the per-slide figure anchors a smoother delivery.

Assumptions and limits
- The result is derived only from the 2 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.
