> **Quick answer —** Microcopy fails on missing context rather than difficulty. A word like Open or Post can be a verb or a noun, and a translator with no screenshot and no character limit guesses wrong about half the time.[Vitra.ai Universe](https://www.vitra.ai/platform) ships product and customer content in every language.

## Short strings are the expensive ones

A thousand words of help content is straightforward work. Forty button labels is not, and it will produce more corrections. The reason is that a short string carries almost no information about itself. "Open" could be a command on a button, a status on a badge, or an adjective in a filter. Every language resolves those three differently, and nothing in the string says which it is.

## Send the context, not just the string

Send

Why

The string

Obviously

A screenshot or component name

Resolves verb versus noun

Character limit

The button is a fixed width

Part of speech, where ambiguous

Removes the guess

Whether it is repeated elsewhere

Consistency

Placeholder meaning

See [do-not-translate lists](https://www.vitra.ai/general/do-not-translate-lists)

A string sent without these is not a task, it is a question — and the answer you get back is a guess that reads fine and is wrong often enough to matter.

## Length is a design constraint

English microcopy is unusually compact. German runs longer, and a button sized to fit "Save" has nowhere to put "Speichern unter" when a label grows.

Two honest options. Give the component room in the source design, which is the same argument as leaving slack in a [banner layout](https://www.vitra.ai/general/banner-localization). Or set a character limit and let the translator write to it rather than translate to it — a shorter, different word that fits beats an accurate one that truncates.

## Do not reuse strings to save money

Sharing one "Open" across six places looks efficient in the codebase and guarantees at least one of the six is wrong, because a single translation now has to serve six grammatical contexts.

Separate keys per context cost nothing and remove a whole class of defect, and [translation memory](https://www.vitra.ai/features/translation-memory) still reuses the ones that genuinely are identical.

## Check it rendered, not extracted

Microcopy problems are invisible in a string file and obvious on a screen.

Run [pseudo-localization](https://www.vitra.ai/general/localized-website-testing) before translation to find the fixed-width containers, then review the built interface rather than a spreadsheet. [Quality control](https://www.vitra.ai/features/quality-control) covers wording; truncation needs the rendered view. Screens built into hardware cannot reflow at all — [infotainment string translation](https://www.vitra.ai/automotive/infotainment-string-translation).

## FAQ

**Why is microcopy harder to translate than long content?** Because a short string carries no information about itself. A word like Open can be a verb, a noun or a status, and nothing in the string tells the translator which, so they guess.

**What context should be sent with UI strings?** A screenshot or component name, the character limit, the part of speech where ambiguous, whether the string is reused, and the meaning of any placeholder. Without those it is a question, not a task.

**Should the same string be reused across the interface?** No. Sharing one label across several contexts guarantees at least one is wrong, because a single translation has to serve several grammatical situations. Separate keys per context cost nothing.

**How should translated microcopy be checked?** On the rendered interface rather than in a string file. Truncation and overflow are invisible in a spreadsheet and obvious on screen, and pseudo-localization finds the fixed-width containers first.
