What it does

Text Stress Test makes every text in your frames as long as it would be in another language, using real expansion data: a six-letter button can double in German, so short labels grow more than long sentences. It works on a labeled copy next to the original, or in place with one-click restore, and keeps bold and link runs as they were.

Then it lists what breaks, in pixels: text cut off by its box, clipped or spilling out of a container, hidden by an ellipsis, compound words wider than their box, line heights too tight for tall scripts, frames that grow. Wrap or shrink to fit with one click, and export the report.

  1. Your UI in 14 languages and scripts

    Real expansion ratios, and short labels grow more.

  2. What breaks, in pixels

    Cut off, clipped, truncated, long words, tight lines.

  3. Try any string first

    German compounds, Japanese, right-to-left, pseudo-locale.

  4. Fix it on the copy

    Wrap or shrink to fit, then export the report for the team.
