Canvas

You can think of a Canvas as a sheet of paper, typically, not necessarily of a standard size such as A1, Tabloid or 8.5 x 11. It represents the total space where any drawing may occur. Typically, though, a margin is specified to preserve empty space along the edges of the Canvas. The margin can be set to zero all the way around if desired.
