How long should an article be? That's a tough question! Generally speaking, it should be long enough to cover the subject thoroughly but short enough not to be repetitive or vague. As a rough guide, Sentinel articles run between 500 and 1,200 words. Shorter articles are preferred. Items for the Journal should be under 2,000 words, and 1,000 to 1,500 words is usually sufficient! If your article is longer than this, put it aside for a few days or weeks and then go through it, looking for places to cut or clarify. By allowing some time to elapse, you will be more likely to spot repetition and excess verbiage.
