# How long should a lead magnet be? A length guide by goal and reader

Long enough to keep its one promise in a single sitting. For a general reader that is about 1,200–1,900 words for a quick win and 2,400–3,600 to teach one method, at 238 words a minute. Pick a goal and a reader for a length in words, minutes and pages.

## Lengths by goal and reader

| Goal (reading time) | Busy decision-makers: founders, executives | General readers and consumers | Practitioners who want the detail |
|---|---|---|---|
| Give a quick win they can use today (5–8 minutes) | 1,000–1,400 words | 1,200–1,900 words | 1,500–2,400 words |
| Teach one method, step by step (10–15 minutes) | 1,800–2,700 words | 2,400–3,600 words | 3,000–4,500 words |
| Show your expertise before a sales call (15–25 minutes) | 2,700–4,500 words | 3,600–6,000 words | 4,500–7,400 words |
| Be the guide they keep and come back to (25–40 minutes) | 4,500–7,100 words | 6,000–9,500 words | 7,400–10,000 words |

Each goal is a reading time, Chapbook's rule of thumb rather than a study of what converts. It is scaled for the reader (busy decision-makers: founders, executives: they read between meetings, so a quarter shorter; general readers and consumers: the times as they stand; practitioners who want the detail: they will read longer for the how, so a quarter longer) and turned into words at 238 words a minute, the average silent reading rate for non-fiction measured by [Brysbaert (2019), “How many words do we read per minute? A review and meta-analysis of reading rate”, Journal of Memory and Language 109](https://doi.org/10.1016/j.jml.2019.104047). Lengths stay inside what a Chapbook lead magnet holds, 1,000 to 10,000 words.

## How the guide works out a length

Each goal is a reading time: a quick win takes a few minutes, a method a quarter of an hour, a reference most of an hour. The guide scales the time for the reader, a quarter shorter for people who read between meetings and a quarter longer for practitioners who want the detail, and turns it into words at 238 words a minute, the average silent reading rate for non-fiction that Brysbaert's 2019 review of reading-rate studies measured. Pages come from the words to pages calculator, for a lead magnet on its usual page and look.

The reading times are Chapbook's rule of thumb, not a study of which lengths convert. Use them as a starting point and let the promise decide: a lead magnet is the right length when it keeps its promise and stops.
