Blog Post Length
Size a blog post from a target reading time and reading speed.
About Blog Post Length
Multiplying the target reading time by the reading speed gives the ideal word count, which then splits into plausible sentence and subheading counts. This is a planning sketch, not a hard rule. A target reading time makes creation time and reader effort predictable, and subheading density keeps long posts scannable.
Formula
Blog Post Length
Words = target minutes x words per minute
- words per subheading
- Assumed spacing between subheadings

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to whole numbers, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
