Speech length usually depends on delivery speed, pauses, and audience. A short one-minute speech often lands near 130 words, while a five-minute speech is commonly around 600 to 750 words.
If you are planning a speech, use the word counter and reading time calculator together. The word counter helps you hit the right length, and the reading time tool gives you a fast estimate before rehearsal.
For presentations, it is usually better to stay slightly under the limit. Natural pauses, transitions, and emphasis often make a speech run longer than expected.
