Why translated marketing and support copy needs its own readability pass, how expansion breaks layouts, and a QA checklist for MT plus human review.
How translation changes layout and rhythm
Expansion, compression, and UI
Translation changes length — German and Finnish often expand; Asian languages may compress ideographically but need different line-breaking rules. UI strings that fit in English may overflow buttons after translation—test in real components, not only docs.
Readability is local
A “good” grade level in English doesn’t transfer metric-for-metric. Still, average sentence length, passive voice, and jargon density are useful within each locale after a fluent edit.
Quality workflow
Glossary through native review
(1) Glossary for product terms. (2) MT draft with human post-edit. (3) Back-translation spot check for high-risk claims. (4) Run readability/NLP stats per language where available. (5) Native reviewer signs off on tone.
SynthQuery tip
Draft in one language, align structure, then localize. Use translator for first pass, then edit for rhythm. Compare against your English SynthRead baselines for relative complexity, not identical scores.
Claims, compliance, and locale law
Regulated claims (health, finance, pricing) need locale-specific review—MT plus post-edit is not enough when a mistranslation creates liability. Keep glossary ownership by market and log who signed off on high-risk strings.
