You can change the size of your printed 3DMap within the size of one page, (maximum printed size will be fitted to page) maintaining the aspect ratio.
Fit to Page
The default Width and Height of the image are automatically displayed. When you choose this setting, the image is saved with the default dimensions.
Custom
When you want to make the image larger or smaller, scale the image by either entering the width or height or resize the window manually. When you change either the height or the width, MapInfo Pro changes the other dimension to preserve the image's proportions.
Width
Specify the desired width of the printed map.
Height
Specify the desired height of the printed map.
