These are the composition types for a poster design:
Rule of thirds
Imaginary lines are applied on the image and divide paper into thirds. The main subject is applied by aligning it on the guide lines and intersection points, placing the horizon on the top or bottom lines.
Golden ratio can also also be called Phi Grid.Golden Ratiodivides a frame into three rows and three columns of equal size, resulting in 1:1:1 vertically and 1:1:1 horizontally
The circular formation draws the eye inward into the image. It is made up of a continuous curve.
Triangle or Pyramid composition
In this composition, the subject’s body forms an upright triangle shape, with the head in the top centre and body expanding below to form a wide base.
This has a solid base and will show stability. It also has Height and Strength.
Connection lines meets in the centre and and expansion lines leaves the centre. These lines have the eye led into the picture.
The L or rectangle
This makes an attractive frame. That frame or rectangle can help to frame a main subject in the picture.
Z composition layout
The Z layout is when you place the items that you want the audience to see first along the top of the Z. Then audience will naturally follow the path of the Z. The goal is to place important information at the end.
