Not confident about design? Let the content lead
Designer analyzes what's already on the slide -- how much text there is, whether there are images, and their proportions -- and proposes several layout options built around that content, rather than making you start from a blank template and guess at spacing. That flips the usual order: instead of picking a design first and cramming content into it, you add content first and let a design form around it.
It's a starting point, not a locked template
Any layout Designer applies is made of ordinary text boxes and images underneath, so you can still drag, resize, or restyle any element afterward exactly like a manually built slide. Treating a Designer suggestion as a first draft rather than a final answer tends to give the best results.
Frequently Asked Questions
The Designer pane isn't appearing at all.
Check that you're connected to the internet and signed in with a Microsoft account -- this feature only works while online and signed in.
Can I still edit a design that Designer applied?
Yes. A layout applied by Designer is just a regular slide underneath, so you can freely move text boxes or images exactly as you would on any other slide.
