Change the Stage size
The Stage size of your document is 750 pixels x 500 pixels. You'll change the Stage size to 640 x 480, a common size that supports a wide variety of screen sizes and resolutions.
- Click in a blank area of the work area to deselect the text block.
- In the Property inspector, you see properties for the entire document. Click the Size button.
- In the Document Properties dialog box, enter 640 for the width and 480 for the height, and click OK.
The document size changes, but the objects on the Stage remain the same size.
