Like with all essay outlines, informative essay outlines too should have a word count limit. Else they would defeat the very purpose of writing them. A good assumption is to use the one tenth fractions wherein the word count of an outline should be one tenth of the actual essay word count. By doing this you ensure that the main essay word count does not increase and at the same time the essay contains relevant and precise information. Depending upon the complexity of the essay you may wish to increase or decrease the word count of the outline. Some templates contain word count limits on the outlines and the essays.
