Best practice
In technical writing, ensure the context clearly defines whether the 'length' refers to physical dimension or temporal duration to avoid ambiguity.
Common error
Do not use 'more' if there is no basis for comparison. For example, 'The rope has a more extended length' is weaker than 'The rope has an extended length' unless you are comparing it to a shorter rope mentioned previously.

Ludwig's WRAP-UP
In conclusion, "a more extended length" is a valid and sophisticated way to express a comparative increase in size or duration. While it is less common than simple alternatives like "<a href="/s/a+longer+length" target="_blank" rel="alternative">a longer length", it carries a formal weight that makes it ideal for scientific research and technical documentation. Examples from Ludwig suggest its most effective use is in contexts where a baseline length has already been established, allowing the comparative "more" to provide clear, incremental meaning. It is perfectly acceptable in high-level writing but should be used sparingly to avoid wordiness where "an extended length" or "longer" might suffice.
