Amoeba PPT Guideline

Last updated September 3, 2021
The standard (4:3) and wide screen (16 :9) aspect ratios are the commonly used ones.
The PPT slide size is specified in the wide screen (16:9) ratio to be used functionally.
The margins are the space between the content and the top, bottom, left and right edges of the screen.
The head, foot and outer margins are defined as fixed values in each breakpoint range so that the single specification can be maintained.
The area excluding the margins, or the text block of columns, has 25 lines and it can determine the character of the text along with the grids.
Columns and Rows
Grids are important guidelines for components and their arrangement. The columns and rows shown in grids are decided by the range of the predetermined screen size. Columns and rows can be selected from scales of 1, 2, 4, 8 and 16 to fit the screen size and direction so that the contents can flexibly adapt to the screen size.

Aspect ratio
For cutting images, the common aspect ratios of 16:9, 4:3, 3:2, 2:1 or 1:1 are used, unless a separate specific format is designated.
Those common aspect ratios work well for the grid foundation.
