When you’re designing your Prezi presentation, make sure your audience will see what (and only what) you want in each frame, by setting the screen resolutions you will be presenting in. It’s easy to tell Prezi what size your screen will be, and if you remember to do that before you begin designing your presentation, you will save yourself a lot of time and faffing.

How do I set my Screen Resolution in Prezi
Click on the cog icon in the top right of the editing screen, or press ctrl/cmnd + shift + m to toggle through the options.
How do I Make my Content Fit the Screen Dimensions?
Whenever you draw a frame, hold shift and it will snap to the dimensions you chose above.
If you click on any path point (in the left hand navigation bar), an orange dotted line will appear – this is the view which will be shown when you present in the screen resolution you chose.
How do I know the Dimensions of the Screen I will be Presenting on?
Ask! That’s the easiest and most foolproof way to know. The general rule is that projectors are 4:3 in resolution, while LCD screens are 16:9. If you can’t find out, your safest option is to make a copy of your presentation in both dimensions, so you can’t be caught out on the day.
