Estimating Speaking Time from a Script

Text metrics reveal length and structure, but clear writing still depends on audience, purpose and careful revision. This guide focuses on a practical situation: speaking is usually slower than silent reading and varies with pauses, demonstrations and audience reaction.

The short answer

A 1,300-word script might fill roughly ten minutes at 130 spoken words per minute before questions. The useful result is not only the final number or code; it is understanding what was measured, what assumptions were made and how the answer will be used.

A reliable step-by-step method

1. 01Define the reader and the action they need to take.
2. 02Draft for meaning before optimising length.
3. 03Review words, sentences and reading time.
4. 04Edit for clarity, accuracy and useful structure.

A practical example

A 1,300-word script might fill roughly ten minutes at 130 spoken words per minute before questions. Start with the information you actually know, keep the original unit or context beside every figure, and avoid rounding until the end. If the result affects money, health, safety or a formal requirement, confirm it with an authoritative source or qualified professional.

Common mistakes to avoid

• Chasing a word count instead of answering the question
• Using reading time as a measure of quality
• Removing necessary detail merely to make sentences shorter

A quick plausibility check is valuable. Ask whether the result is in the expected direction, whether the scale makes sense, and whether another person could understand the assumptions from your notes.
