If your presentation consistently runs over, trying to fix it by speaking faster is usually the wrong answer. The better solution is to reduce the amount of content you need to deliver. Speaking faster makes you harder to follow and more likely to stumble, and it saves less time than you expect.
Here is how to find the extra minutes and remove them without losing your message.
First, measure the gap
You cannot cut precisely until you know how much is too much. Work out your word budget: your speaking pace times your time slot. At a conversational 130 words per minute, a 12-minute talk is about 1,560 words. If your script is 2,000 words, you need to lose roughly 440.
Where the time usually hides
Most overruns come from a few predictable places:
- A long warm-up. Throat-clearing openings (“before I start, a little about me…”) burn a minute before you reach the point. Start closer to the substance.
- Too many points. Three well-made points beat six rushed ones. Cutting a whole weak section saves far more than trimming words everywhere.
- Wordy sentences. Spoken scripts fill with filler: “what I want to do here is basically talk about…” becomes “here’s…”. Tightening phrasing across a script easily removes ten percent.
- Backup and detour slides. The “just in case” slides and the tangents you love but the audience does not need.
- Reading the slide aloud. If the slide already says it, do not also narrate it word for word.
Cut sections, not just words
When you are more than a minute or two over, trimming adjectives will not get you there. Look for a whole point or example you can remove. It feels harder, but the talk almost always improves: what is left is sharper, and you stop rushing. Ask of each section, “if I cut this, does my main message still stand?” If yes, it is a candidate.
Protect time for questions
If your slot includes Q&A, that time comes out of your script first, not out of thin air at the end. A 20-minute slot with five minutes of questions is a 15-minute script. Budget it up front and you will not get cut off mid-conclusion.
Read it aloud and time it
Silent reading is much faster than speaking, so it hides overruns. Read the trimmed script out loud at your real pace and time it. If you are still over, repeat the cut. This is also when you catch the sentences that are fine on the page but run long in the mouth.
Find the long sections automatically
Reading and timing the whole deck by hand is slow, and it does not tell you which slides are the problem. That is exactly what ScriptAssist Presentation Timing does: it estimates the time for every slide and section from your PowerPoint speaker notes, keeps a running total, and, once you set a target, highlights the slides most likely to push you over. Instead of guessing, you can see the two or three slides that are eating your buffer and trim there.
For a quick check of a single script, the free Script Time Calculator gives you the number to aim for in seconds.
