Translating user manuals: what manufacturers need to know
Translating user manuals into all EU languages: what is legally required, which approaches exist, what agency and machine translation cost, and how to keep the layout intact.
If you sell products in Europe, you supply the manual in the language of the target country. That is not a service extra but a requirement. For manufacturers and importers that means: every manual appears in many language versions, for every product, again with every change. This guide explains what is required, which translation paths exist and where projects fail in practice: rarely on translation itself, almost always on layout, terminology and turnaround time.

What the law requires
Language requirements come from several EU acts at once. The General Product Safety Regulation requires instructions and safety information in a language consumers in each member state can easily understand; member states set that language, in practice the respective official language. For machinery, electrical equipment, toys and other CE product groups, separate acts apply with matching language duties. If you supply retail chains in several countries, you often receive the language list directly from the retailer.
The consequence: the question is not whether to translate but how economically and quickly 10, 20 or more language versions can be produced without quality and layout suffering. Which language versions are mandatory in a given case is clarified by the relevant act or the trading partner's specification.
Three approaches compared
Path 1: Translation agency. Professional translators deliver reviewed quality, optionally with four-eyes review to industry standards. The price is word rates in the high single-digit to low double-digit cent range plus project fees and typically one to two weeks turnaround per order. With 20 languages and ongoing product changes that quickly becomes one of the largest line items in documentation.
Path 2: Translate yourself with standard tools. Usable for internal purposes. For mandatory documentation this path fails in three places: technical terms are translated inconsistently, the InDesign layout must be fixed by hand after each language, and nobody documents what was reviewed. The seemingly free option is paid for by rework in the graphics department.
Path 3: Machine translation with a specialised tool, plus revision where needed. Modern machine translation handles the language transfer in minutes. What matters is the surrounding process: a tool that processes InDesign files layout-faithfully, a glossary that keeps technical terms and protected names consistent, and a workflow that adds human revision where it is required. That produces all language versions in one pass, and agency or specialist revision focuses on the cases that truly need it.
The layout problem (and why it is the real one)
Manuals are built in InDesign. If you copy text out for translation, you pay twice: once for translation, once for rebuilding the layout in each language. French runs longer than German, Greek and Bulgarian bring their own scripts, and every text box shifts.
The cleaner path goes via the IDML format: export the InDesign file as IDML, translate it and get it back translated, with layout preserved and still editable. That is what IDML-Translate is built for: upload the file, choose target languages, receive all language versions in one pass. Before you start, a free preview shows scope and cost; files are deleted after 24 hours and not used for model training.
Quality and proof
For mandatory documentation what counts is not only the translation but proof of how it was produced. Two industry standards set the frame: the standard for post-editing of machine translation and the standard for translation services with four-eyes review by qualified translators. In practice a staged process works well: machine for the full transfer, human revision for safety-critical passages, documented per order. That yields a solid quality record without paying the full agency process for every language.
Frequently asked questions
Which languages must a user manual be translated into?
Into the language set by each EU member state, in practice the official language of every country where the product is sold. Retail chains often specify the language list contractually.
What does translating a user manual cost?
Agencies charge per word and language plus project fees; with many languages that quickly reaches five figures per manual. Machine translation with a layout-faithful tool costs a fraction; the exact amount can be calculated upfront via a preview before any order is placed.
How long does translation take?
Agency projects typically one to two weeks per order. Machine output creates all language versions in minutes; with targeted revision of safety-critical passages it stays at a few days.
Does the InDesign layout stay intact during translation?
Yes, when working via the IDML format: export IDML, translate, open the translated file in InDesign again. Text length changes per language, but the basic layout and all formatting remain and stay editable.
Is machine translation enough for mandatory documentation?
Yes for the full transfer, not always as the sole process depending on requirements. What works is the combination: machine for volume, human revision to standard for the passages that matter, with a documented review step.
Can multiple languages be translated at once?
Yes. IDML-Translate processes one file into many target languages in one pass, including variants of all EU official languages.
