Diff Checker for print — pages, columns, and layout estimates

Using Diff Checker to estimate how text will land on a printed page. Browser-based, free, no signup, runs entirely on your device.

Most inputs you work with don't justify opening Word. Diff Checker is for the in-between cases — paste, transform, paste back. Browser-local, no signup, no character limits.

Run it in your browser: Diff Checker — No upload, no signup, no daily limit.

Diff Checker for print layout

Print spaces are unforgiving. A column estimate that turns into one extra line forces a layout do-over. Diff Checker gives you the count before you commit to a layout, so you can edit copy down to fit rather than re-flowing the whole document.

Frequently asked questions

Does Diff Checker count characters with or without spaces?

Diff Checker shows both counts simultaneously, so you can use whichever your target requires.

Is there a length limit?

Practically, several MB of text. Beyond that the browser starts to lag.

Does Diff Checker save my text?

No. Diff Checker processes everything in your browser; nothing is uploaded or stored.

Can Diff Checker handle non-English text?

Yes — it uses Unicode-standard rules that work for most major scripts.
