Is 500 words enough, should you aim for 1,000, or does a substantial article need to push towards 2,000?
The difficulty is that we use written content in very different ways. A blog post might take five minutes to read, while a long-form essay could demand half an hour. An email newsletter may need only a few hundred words, a social media caption might do its job in two sentences. Case studies, guides, landing pages and reports all come with their own expectations. A useful answer must therefore begin with an understanding of what the content is trying to achieve.
Whatever the format, its value ultimately comes from the effectiveness of its message. Does it hold your attention, explain something well, persuade you or help you make a decision? Those qualities are difficult to measure, which may explain why word count can exert disproportionate influence.
The seductive certainty of a word count
Word count is a seductive measure of effort because it gives us a nice, neat number. We can easily measure 1,500 words, compare them with 800 and conclude that somebody has produced considerably more. Enjoyability or persuasiveness, on the other hand, cannot easily be entered into a spreadsheet.
That becomes particularly tempting when the work needs to be approved by somebody else. A long article looks substantial, a detailed report looks industrious, and twenty pages can appear to represent greater effort than five. The writer can soon find themselves demonstrating how much work went into the document instead of concentrating on how well it communicates.
Once length starts to feel like evidence of a job well done, unnecessary words acquire a strange sense of value. An idea gets another paragraph, a useful example gets three companions, and explanations begin to need explanations of their own. This notion is investigated further in the article Better Marketing Beats More Marketing Every Time.
Who are you actually writing for?
While your boss may approve the article, it is your customer who is giving you their time and attention. They arrive with a question, an interest, a problem or a decision in mind. Your job is to help them make progress, rather than prove how much effort went into helping them.
This becomes especially important when you know your subject well. Expertise gives you plenty to say, but it also creates a responsibility to decide what your reader needs to hear. Straightforward communication usually serves the reader better than clever or elaborate language, particularly when your aim is to explain something useful. If you can do that in 800 words rather than 1,500, making someone read the additional 700 does not improve the first 800.
Even excellent writing eventually reaches its limit. You can have too much of a good thing, however enjoyable that thing happens to be. A wonderful dinner is something to savour, but very few people would finish it and immediately request another two dinners simply because the food was nice.
When more words start working against you
Repetition is usually the first warning sign. A useful point gets made, then restated in slightly different language, followed by another example proving something the reader already accepted. What feels like reinforcement to the writer can feel like unnecessary delay to the reader.
Extra length can also make the subject unnecessarily complicated. Qualifications lead to side arguments, side arguments require explanations, and the main point gradually disappears beneath information that seemed useful when it was added. Eventually there is an even simpler risk: the piece becomes boring.
Boredom can undo some of the good work that came before it. A reader who enjoyed the first 700 words may leave with a less favourable impression after struggling through another 800. Knowing when you have said enough is part of communicating well.
Give the article the space it deserves
So, the only useful guide to length is intent. Decide what you want the reader to understand and what value you want to give them, then allow the subject the space it needs to achieve that purpose. Some ideas deserve considerable depth, while others can be covered perfectly well in a few paragraphs. Give worthwhile points room to develop, remove whatever is merely taking up space, and let the final word count follow from the quality of the communication. When the message has done its job, the article is long enough.
