Localization is the process of adapting documentation for a specific language, culture, and region — not just translating words but adjusting examples, conventions, units of measurement, date formats, cultural references, and assumptions for the target audience. Its companion process, internationalization, is the design of content so that it can be localized without structural changes.
Localization matters for technical writers because documentation increasingly serves global audiences. A user guide written for American readers may use imperial measurements, American date formats (MM/DD/YYYY), and culturally specific examples that confuse readers elsewhere. Localization-aware writing anticipates these problems at the source.
Principles for writing that localizes well:
- Use simple, consistent sentence structure. Complex sentences with multiple clauses are harder to translate accurately. The plain language principles in this vault — short sentences, active voice, one idea per sentence — also produce content that translates cleanly.
- Avoid idioms and culturally specific references. “Hit the ground running,” “out of left field,” and “ballpark figure” are opaque in translation. Use literal language.
- Use consistent terminology. If the same feature is called “dashboard” in one place and “control panel” in another, translators must guess whether these are the same thing. A style guide with a term list prevents this.
- Leave room for text expansion. Translated text is often 20–30% longer than English. Interface text, button labels, and column headers must accommodate this expansion.
- Separate content from presentation. When content is embedded in code or tightly coupled to layout, localization requires engineering work alongside translation. Topic-based authoring helps by keeping content modular.
The broader principle is that writing for a global audience is not a constraint but a discipline — it produces clearer, more precise writing for all readers, including English speakers.
