How it works Prompt Size Estimator
The estimator starts with the text itself and translates its length into common planning units, helping non-technical stakeholders understand prompt size.
Example
Paste documentation or a product specification to turn its length into pages, reading time, and a token estimate.
Frequently asked questions
- How is reading time calculated?
- It uses a conventional 200 words per minute reading estimate.
- Are pages standardized?
- Page length is only a rough communication aid; font, spacing, and formatting change real page counts.
