Part of: Readability Guidelines
Last updated: 11 December, 2019
Complex sentences take more brain power to process, make readability more difficult for low literacy level users and are harder to translate.
People are more used to reading lowercase letters so comprehension is slower for capitalised words.
This reduces user confusion. Exceptions: when users know them better in abbreviated form, for example GIF and 5KB.
This may reduce distraction and cognitive load. It can work better for users with autism.
It’s generally not necessary and can easily make your content non-inclusive.
Research what language could be emotive for your users by exploring forums, blogs and social media, and carrying out user testing.
Using plain, simple language, short sentences, active tense, good grammar and accurate punctuation helps make content easier to translate.
