Translation Text Expansion Estimator

Estimate layout pressure using source length and a clearly labeled language-pair heuristic. It gives designers a capacity range, not a prediction of the final translation.

Layout allowance

Your result will show a character range and an estimated line range at the capacity you enter.

The visual is a planning cue. It does not simulate a font or translate the text.

How to use the range

Character count is a rough proxy for space. Actual fit depends on glyph width, script, wording, font, size, direction, line breaking, and the translator's choices. The estimator applies a deliberately broad multiplier to the visible source characters and converts that range into lines using the capacity you provide.

Count only text that will appear in this container.
Estimate line capacity from the current design, not the full page.
Run separate estimates for labels, captions, and body copy.

Flexible paragraph

Let the container grow vertically and test natural line breaks before changing the type size.

Narrow label

Plan a shorter approved wording, a wider field, or a stacked layout. Do not clip meaning to preserve symmetry.

Table or graphic

Check each cell, caption, and callout separately because the overall average can hide one severe overflow.

Measure the translated text before publishing

This estimate is for an early wireframe. It does not know the target sentence or its typography. Place the real translation in the actual container, inspect it at the intended screen size, and ask a native reader to review forced abbreviations. The guide to preserving layout during image translation covers the reconstruction work that remains.

Move from allowance to real copy

Treat the range as an early design allowance. Translate the verified source, place the real output in its container, and check every changed line break manually.
