Motivation letters for German universities
German admissions are documentary. Much of the decision rests on whether your degree is recognised, whether your grade converts acceptably under the modified Bavarian formula, and whether you have the specific module credits the programme requires. The motivation letter sits on top of that and is read for coherence, not for personality.
This is the most common mistake applicants make here: sending an emotive American-style essay to a committee that wanted one page explaining why your bachelor's coursework prepares you for their master's.

What goes on the page
Open by stating the programme you are applying to and, in one sentence, the specialisation you intend to pursue. Then the academic argument: the relevant coursework, the thesis or project, and the specific gap the master's fills. Then the institution: which chair, which lab, which module group, and why it is the right one. Close with the professional intent in two sentences.
There is no space for a narrative opening. A one-page letter with a paragraph of scene-setting has surrendered a quarter of its argument.
- Business-letter header: your address, the institution's address, place and date
- A subject line naming the programme and, where relevant, the application number
- Formal salutation; use the named admissions contact where one is published
- Three to four body paragraphs, no subheadings
- Signature block; a scanned signature is normal on PDF submissions
uni-assist, module lists and grade conversion
Many German universities process international applications through uni-assist, which checks your documents against the programme's formal requirements before the university sees them. If your transcript does not evidence the required credits in, say, mathematics, no motivation letter will rescue the application.
Where your coursework covers a requirement under a different course title, say so explicitly in the letter and attach the module description. This is one of the few places where a motivation letter genuinely changes an outcome.
German-taught versus English-taught programmes
English-taught master's programmes accept an English letter. For German-taught programmes, write in German: submitting English to a German-taught programme raises the obvious question about your C1 certificate. We work with a German-language editor for those; say so when you enquire.
Questions about applying to Germany
How long should a German motivation letter be?
One page. Roughly 400 to 600 words in a business-letter layout. Two pages is acceptable for research-heavy programmes but is not the norm and should be a considered choice.
Do I write the motivation letter in German or English?
Match the language of instruction. English-taught programmes expect English. German-taught programmes expect German, and a letter in English undercuts your claimed language level.
Does a DAAD scholarship need a different letter?
Yes. DAAD assesses against its own criteria, including relevance to development in your home country for several programme lines, and it expects a fuller letter than a university admission. It is a separate document.
