With a degree of pomposity, the University of Huddersfield, UK, tells us that, "[i]t must be remembered that the purpose of a paragraph is to develop a point or specific theme. With this in mind, a single sentence or two would probably not be sufficient to fulfil this purpose. Development of a point requires discussion and explanation, which suggests that a minimum of five or six sentences is advisable."
Codswallop!
And if you don't believe me, believe the experts at the Poynter Institute, who assert that ""stories with shorter paragraphs get more than twice as many eye fixations than those with longer paragraphs" and that "the longer-paragraph format discourages reading and that short-paragraph format overwhelmingly encourages [it]..."
This is why short paragraphs (1-3 sentences or less) are used in news stories where the emphasis is on reporting information without discussion, and in technical writing where the emphasis is on presenting facts without analysis.
Written dialogue also consists of short paragraphs, with a new paragraph for each change of speaker.
Here are six rules:
A single paragraph should concern itself with a single focus. If it begins with one focus or major point of discussion, it should not end with another or wander between different ideas. And if you begin to transition into a new idea, press 'Enter'.
Ensure that the connections between sentences are clear. This smooth, logical flow is called paragraph coherence, and it's easy to achieve if you write each sentence with the previous one in mind; if you pick up a tidbit from one and carry it to the next.
Transitions are sentences or short phrases that "transition" a paragraph into the next. Some examples are: in addition, again, moreover, further, first, second, however, although, accordingly, consequently, in the meantime, on the other hand, and so on.
If paragraphs and sentences share a consistent length, even a short one, the result can become a monotone; a flat landscape. Easy to traverse, but boring. So, although the rule is 'Keep it short', try to create content that has contours and variety.
Use paragraphing to give your readers a pause. Breaks in paragraphs - ie white space - give your readers important visual breathing room, give your content slightly more drama and gravity and, critically, make your writing more readable.
The old fogies teach that we should never write a one-sentence paragraph. Nonsense! If you can say what you want to say in a single sentence that lacks a direct connection with any other sentence, just do it. Your readers will thank you.
And on that note, thank you for your kind attention. Goodbye, and good luck.
