Setting Page Size and Document Preview

When you create a document, you specify its page size as Handheld or Computer, depending on how you expect the document to be used. Documents of both page sizes can be opened on either platform, and you can convert the page size any time.

Handheld. Size: 320 × 217 pixels, fixed. Handheld documents can be viewed on all platforms. You can magnify (zoom) the content when viewing it on a tablet or larger screen.
Computer. Size: 640 × 434 pixels, minimum. Computer documents scale up automatically to take advantage of higher resolution screens. The minimum size is 640 × 434, so some content may be clipped on handheld devices.

Note: You can view documents of either page size using Handheld or Computer preview.
