If you’re writing an article or story for a magazine, think about your paragraph lengths. When you send your work out, your pages are A4 size. The lengths of your paragraphs may look short on a page that size but imagine them in a newspaper or magazine. You can fit about 16 words or so into a single sentence of A4, but in a newspaper/magazine, this is more than halved, meaning your paragraphs will be much longer in the publication.
Some newspapers use very short paragraphs, often only one sentence in length, so check the publication you’re writing for carefully and bear it in mind when working on your full piece.
