Sizing stage for slide presentation

Hi everyone,

I want to use flash instead of powerpoint to create a slide presentation but I’m not sure what size to make the stage. Whenever I’ve used powerpoint in the past, it’s always just come up with a default slide size, but I’m not sure what this translates to into pixels so I can do something similar in flash.

Would someone have any idea how big I should make the stage?

Would really appreciate any tips.
