The type is set with even word spacing and each of the lines will vary in length. The even word spacing creates a uniform overall texture. It is ideal for setting type in narrow columns. Hyphenation of words is at a minimum. The risk of rivers of white flowing down the page is eliminated.

The ragged edge of the right adds visual interest to the page. Disadvantages If lines are set the same approximate length it can be a disturbing factor in the design. It is important that the ragged edge should create a pleasing silhouette, convex rather than concave. Centered In this arrangement, the lines of type are centered on the page. When using centered type the length of the lines must be varied enough to create an interesting silhouette.
