Speech Time Calculator

Speech duration equals total words divided by speaking rate in words per minute (WPM). Conversational English is often 120–150 WPM; practiced presenters may slow to 100–120 for clarity or speed up for time-limited pitches.

Pause for applause, slides, and audience questions is not included — add buffer for classroom or conference formats. Reading aloud from a script usually runs faster than extemporaneous speaking with planned pauses.

Example: a 1,300-word essay read at 130 WPM takes about 10 minutes. At 150 WPM the same text finishes in roughly 8 minutes 40 seconds — adjust rate to match your rehearsal timing.

Different formats have different natural rates. Audiobook narration is usually mastered around 150 to 160 WPM, broadcast news reads near 150 to 180, conference talks land between 120 and 150, and wedding or eulogy delivery slows to 100 to 120 because pauses carry the emotion. Pick the rate for the room rather than a single default.

Slides and applause are not in the word count. Add 30 to 60 seconds for every slide you actually stop to discuss, and 10 to 15 seconds for each laugh or applause break — a 20-slide deck can add 10 minutes to a script that reads in 15.

To find your own rate, read one page aloud at your real delivery pace, count the words, and divide by the minutes it took. Most people discover they speak 10 to 20 WPM faster under nerves than in rehearsal, so timing a dry run at your natural pace beats trusting the 130 WPM default.

Working backwards is often more useful than forwards. A 5-minute slot at 130 WPM means about 650 words, and a 10-minute conference talk means roughly 1,300 — write to that budget rather than trimming a finished script.

Reading from a script normally runs faster than speaking from notes, because extemporaneous delivery carries hesitations and restarts that a script removes. If you plan to speak from bullet points, lower the rate by about 10 WPM from your scripted rehearsal.

Panel discussions and Q&A add time beyond word count ÷ WPM — pad 20–30% for conference formats.

For timed exams or grant pitches, rehearse aloud once and compare actual minutes to this estimate before committing to a slot length.
