It is always a good idead to keep paragraphs as short as possible. Long paragraphs make it difficult for readers to skim the article and helps to keep one's eyes from glossing over. Similarly, extremely long sentences should be avoided. As a general rule, articles on this wiki should use only the amount of writing necessary to thoroughly cover all of the relevant material; saying a lot without using a lot of words to do it. Keeping an article's length short is not always achievable because some articles will always require a lot of information to be provided, but being concise should be a relative goal in writing and editing articles.
