In the report properties, depend on the “Paper size”, Visual Studio sets automatically the width of the page.
We must consider left and right margins too.
The space that we can use is:
Paper width – left margin – right margin
In our case:
8,27 – 0,7 – 0 = 7,57 in
The body width does not be greater than this size. To control the body size:
Right click on the body layout > Properties:
If the body size is greater than the paper size (with margins), the system adds extra white pages.
