A:Answer The width is 6-1/4". Depth of the body is 8-1/2". Add to that depth another 4" for the paper holder with a full roll of paper in it. Height of the body is 2" at it's 'tallest' point. The paper roll assembly by itself, on the calculator, with a full roll of paper is 3-3/4" tall. So, it'll fit into a space that's 6-1/2" wide by 13-1/2" long by 4-1/2" tall.
