Notes

It fills whatever width you give it, down to phone screens.
It follows your reader's light or dark mode automatically.
It does not track your visitors. No cookies, no analytics and no outside files. The numbers typed are sent to smartfin.fyi, which works out the result.
A height of 1890 suits most layouts. Increase it if your site uses larger text.
The credit line under the widget is optional. Keep it, delete it, or add rel="nofollow" to its link. The widget works the same either way.

Terms: there aren't many. Use it on any site, including commercial ones, at no cost. We may improve the calculator over time, so the embedded version can change. If it ever needs to be retired, this page will say so first.
