About Text Density
Dividing total words by paragraph and sentence counts reveals how tightly packed the prose is on average. Screen readers fatique quickly on dense blocks, so density flags where text needs shorter sentences or more breaks.

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 1 decimal place, 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.
