Variety is an important factor in the reader's level of interest. This tab shows graphical distributions of sentence type, length, and word length. Each is a moving average, with word length weighted to the sentences before and after. Remember that rolling waves are good, flatness is boring, and choppiness is jarring. Flow can be altered by adding, removing, lengthening, shortening, combining, or splitting sentences. If you don't see the peaks and valleys in the graphs, try tilting your head to the right. Click each type of meter for more specific explanations.

Sentence type flow
Pieces with good flow will make use of all four sentence types, varying them to keep the reader interested.
Sentence length flow
Sentence length is indirectly related to sentence type, and is a good indicator of flow. Flow can be altered by adding, removing, lengthening, shortening, combining, or splitting sentences. Long sentences will be indicated by a red line on the graph. Sentences that flow poorly with their surroundings will be orange, and the source of the problem can often be found in a nearby sentence.
Word length flow
Word length is a minor contributor to overall flow, but even minor variations are signs of good rhythm.
