If you try to increase the height and width of a project page too much, you may get the error message "The page height you entered was invalid".
If you are working on a large poster, for example, the project page doesn't need to be the same size as the final poster.
To create a poster which is 4 meters (about 13 feet) wide, you can scale the project down 50% and set the page width to 2 meters (6.5 feet).
The project page and margins can be set to a value between 1.3 and 2.75 cm max (about 0.5 to 1.1 inches).
Edit the file as needed and then print it using the appropriate scale factor (e.g. 2x).
The printed result will look exactly as if you had created the original file using the full dimensions.
For bitmap images, the software also retains the original, high-resolution image to be used for export or printing.
