Speech Length Guide: Word Counts for Every Presentation Length

How long is your speech? How many words do you need to write? Whether you are preparing a 2-minute elevator pitch, a 10-minute conference talk, or a 45-minute keynote, the answer depends on one variable: your speaking speed in words per minute (WPM).

This guide gives you a complete reference table for every major speech length from 1 minute to 60 minutes, at three speaking speeds. It also explains the real-world word count targets for specific formats — TED Talks, business presentations, classroom speeches, wedding toasts, podcast episodes, and YouTube videos.

The complete word count reference table

Every number in this table uses three standard speeds: slow (100 WPM), average (130 WPM), and fast (160 WPM). Average is the most useful benchmark for formal presentations, business talks, and classroom speeches.

Highlighted rows represent the most common speech lengths in practice: 5, 10, and 20 minutes for business contexts, and 18 minutes for TED-style talks.

Word counts by speech format

Different speaking contexts come with unwritten conventions about length. Here is what each major format looks like in practice.

Elevator pitch (60–90 seconds)

An elevator pitch runs 130–200 words at average pace. The term comes from the idea that you should be able to explain your business, project, or idea in the time it takes to share a lift with someone. In practice, most investors and event formats give you 60 or 90 seconds — not a full two minutes.

Target: 130–195 words at 130 WPM.

Wedding toast (2–4 minutes)

Wedding toasts are typically 2–4 minutes. Going shorter can feel rushed or underprepared. Going significantly longer tests audience patience — especially at a reception where people are waiting to eat.

Target: 260–520 words at 130 WPM. Aim for 3 minutes (390 words) as a sweet spot.

Classroom speech (5–10 minutes)

Most academic public speaking assignments fall in the 5–10 minute range. These speeches are often timed strictly — the instructor stops you at the limit. Write to the low end of your WPM range so you have buffer room.

Target: 500–1,000 words at 100 WPM, or 650–1,300 words at 130 WPM. When in doubt, aim for 100–110% of your target word count and practise cutting on the fly.

Business presentation (10–20 minutes)

A typical conference session slot of 20 minutes (including 5 minutes of Q&A) leaves you 15 minutes of speaking time. At 130 WPM, that is roughly 1,950 words of prepared material.

Most experienced business presenters write 20–25% less than the word count their slot suggests, then fill the remaining time with Q&A, live demos, or discussion. A 1,500-word script for a 15-minute slot gives you room to breathe without rushing.

TED and TEDx Talks (up to 18 minutes)

TED's 18-minute limit is legendary, and deliberate — TED's curators have said 18 minutes is long enough to take a topic seriously and short enough to hold attention without a break. Most TED Talks are delivered at 150–170 WPM (faster than a typical presentation), and heavily rehearsed.

Famous examples give useful anchors:

• Simon Sinek, "How Great Leaders Inspire Action" — 17:58, approximately 2,700 words, ~150 WPM.
• Brené Brown, "The Power of Vulnerability" — 20:19, approximately 2,900 words, ~142 WPM.
• Ken Robinson, "Do Schools Kill Creativity?" — 19:24, approximately 3,100 words, ~160 WPM.

Target for an 18-minute TED-style talk: 2,340–2,880 words at 130–160 WPM.

Keynote speeches (30–60 minutes)

Full keynotes at conferences typically run 30–60 minutes. At this length, presenters rarely script every word — they use an outline with scripted key passages, especially for opening and closing. This is deliberate: word-for-word scripts at 45+ minutes feel robotic and are extremely hard to memorise.

If you are writing a full script for a 30-minute keynote, plan for 3,000–4,800 words depending on pace. If you use a structured outline, your script might be 1,500–2,000 words of scripted passages, with the rest delivered conversationally.

Podcast episodes

Scripted podcast episodes (like narrative journalism or solo commentary shows) are usually written at 150–160 WPM. A 20-minute episode needs approximately 3,000–3,200 words. A 45-minute episode needs 6,750–7,200 words.

Most podcasters do not script every word — they use bullet-point outlines and speak conversationally. But for anyone scripting a solo podcast, these numbers give you a clear target.

YouTube videos

Scripted YouTube narration typically runs at 150–170 WPM — similar to audiobook pace. A 10-minute YouTube video at 160 WPM needs 1,600 words of scripted narration. A 20-minute video needs roughly 3,200 words.

Videos with heavy visual or B-roll content often have less spoken text, since the script pauses for footage to carry the narrative. Plan for 120–140 WPM if your video has frequent visual breaks.

How to use word count targets in practice

Step 1: Know your time slot exactly

Never assume your time slot. Confirm whether it includes Q&A, transitions, or a moderator introduction. If you have 20 minutes total with 5 minutes of Q&A, your speaking window is 15 minutes.

Step 2: Measure your personal WPM

Read 500 words out loud at your natural presentation pace and time yourself. Divide 500 by the minutes elapsed. Use this number — not the 130 WPM average — as your planning baseline.

Step 3: Write to a word count, then time out loud

Use your WPM to calculate a word count target, write to that target, then do a full read-aloud timing. The first full reading usually runs 5–10% longer than the word count calculation suggests because of natural pauses, emphasis, and stumbles on first read-through. Adjust and re-time until you are consistently within 10% of your target.

Step 4: Build in a buffer

Practise at 90–95% of your time limit. Live delivery almost always runs longer than home practice because of audience reactions, technical pauses, and the natural tendency to slow down under pressure.

Common mistakes when estimating speech length

Mistake 1: Reading silently to estimate time

Silent reading speed is typically 250–300 WPM — roughly twice speaking speed. A script that takes 5 minutes to read silently will take 9–10 minutes to deliver out loud. Always time yourself speaking, never reading silently.

Mistake 2: Using someone else's WPM

The 130 WPM average is useful for planning when you do not know your own pace. But it can be off by 20–30 WPM for any individual. A speaker at 100 WPM who plans a 10-minute talk at 130 WPM will write 1,300 words — and then run 13 minutes on stage.

Mistake 3: Ignoring non-speaking time

Pauses, audience responses, slide transitions, live demos, and the time it takes to walk to the podium all eat into your slot. A 20-minute presentation might have 2–3 minutes of non-speaking time built in. Account for it in your planning.

Mistake 4: Not practising to time until the day before

Most speakers discover they are significantly over or under time only when they first run through the full talk with a timer. Do this at least a week before your presentation so you have time to cut, add, or restructure.

Quick reference by speech length

If you just need a fast answer, here are the most common speech lengths and their word count targets at average pace (130 WPM):

• 1 minute — 130 words
• 2 minutes — 260 words
• 3 minutes — 390 words
• 5 minutes — 650 words
• 10 minutes — 1,300 words
• 15 minutes — 1,950 words
