Design the PowerPoint 2007 Page Setup
The PowerPoint 2007 Page Setup group consists of a Slide Orientation control so you can display your PowerPoint presentation in Landscape mode (the default) or Portrait mode. You should use Portrait mode only if you intend to print the slides on transparency masters and project them with an overhead projector, or present the slide show on a computer screen with a portrait orientation.
Click the Page Setup button in the Page Setup group to display the Page Setup dialog box. This dialog box gives you extra control over your presentation’s page setup.
The following list describes the controls in this dialog box:
Slides Sized For: This drop-down list lets you set the size of your slides based on how you plan to present them. The most common is to present the slides on a standard computer screen, which has an aspect ratio of 4:3. Other options on this drop-down list include different screen ratios, suitable for wide-screen displays, standard sized paper, and even 35-mm slides. A Custom option lets you set any width and height.
Width: Set a custom width for your slides.
Height: Set a custom height for your slides.
Number Slides From: If your slides include numbers, this option lets you set the number for the first slide. The default is 1.
Orientation: Set the orientation to portrait (tall and skinny) or landscape (short and fat). You can set the setting separately for your slides, handouts, and notes. The most common setting is for the slides to use landscape orientation and the notes and handouts to use portrait.
