Some writing experts say that 3 sentences is the sweet spot for a paragraph, as it allows for a clear topic sentence, evidence or explanation, and a concluding sentence. However, this can vary depending on the style and tone of the writing. For example, in journalism, paragraphs are often shorter and punchier.
In fact, did you know that the average paragraph length in a newspaper article is around 2-3 sentences? This is because journalists need to grab the reader's attention quickly and concisely. But, in blogging, paragraphs can be longer and more conversational, with 4-6 sentences being the norm.
