Data sources
Every number a tool compares your text against is listed here with its source. No source, no figure — if we can't point to where a number comes from, it isn't on the site.

Notes on figures we chose not to pin down
- Search title tag / meta description lengths (~60 / ~160 characters): Google does not publish a fixed character limit — titles and descriptions are truncated by pixel width, not character count, so these are widely used practical guidelines rather than hard limits. We label them as a "guide" on the Character Counter for that reason.
- Speaking pace (130 words per minute): published estimates for presentation speaking pace vary roughly 110–150 wpm depending on the context and the speaker. We use 130 as a middle estimate rather than attribute it to one study.
- Facebook post length: we could not find a figure we were confident is still current (older reporting cites 63,206 characters from a 2011 change; current scheduling-tool documentation cites lower numbers that may reflect that tool's own limit rather than Facebook's). We left it off the Character Counter rather than publish a number we can't stand behind.
