Estimate talking time and slide count from words per slide.
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.
