Introduction
🌀 Insight: Page Setup in Gamma allows you to customise the structure and appearance of your gamma.
With this feature, you can:
Modify slide sizes and layouts.
Change backgrounds.
Optimise SEO metadata.
Configure export settings.
Step 1: Access Page Setup
Open your gamma.
Click the three-dot menu (…) in the top-right corner.
Select Page Setup.
Step 2: Adjust Slide Size
In the Page Setup menu, locate the Slide Size dropdown.
Select a fixed height option to maintain consistency.
This setting ensures your content fits within specified dimensions, ideal for exports such as PowerPoint slides or social media posts.
How to Modify Backgrounds
Step 1: Enable Background Display in Present Mode & Exports
Show Slide Backdrops is only in Classic gammas (ones with a Theme button). Gamma 5 slides fill the frame edge to edge in Present mode and exports, so there's no backdrop toggle. See the FAQs below for a workaround.
In Classic gammas, Gamma blurs out the background in Present Mode and exports by default. To keep the background visible:
Go to Page Setup.
Toggle on Show Slide Backdrops.
Step 2: Change the Background
To customize the background:
Click the Background tab in Page Setup.
Choose one of the following options:
Upload an image from your device.
Search for an image online.
Select an Unsplash image.
Use a GIF as a background.
Generate an AI image.
FAQs & Common Issues
Why isn’t my slide height consistent?
Ensure you have selected a fixed height from the Slide Size dropdown in Page Setup.
Why is my background blurred when presenting?
In Classic gammas, toggle on Show Slide Backdrops in Page Setup to keep the background visible. Gamma 5 doesn't have this toggle.
Where is Show Slide Backdrops in Gamma 5?
It isn't available in Gamma 5. Classic gammas still have it in Page Setup.
To get a card-on-background look, right-click the slide and choose Change background, or select the slide and click Background image in the toolbar. Use Overlay to dim the image if you need to.
Then put your text in a text box and give it a Background fill color, so it sits on top like a card.
This is set slide by slide. There's no deck-wide setting for it in Gamma 5.
Can I change the gap between my slides or sections?
No. The space between cards is fixed in both Gamma 5 and Classic gammas.
In Classic gammas, you can remove it: open Page Setup, go to the Slides (or Sections) tab, pick the Custom style, and turn on Full-bleed slides (or Full-bleed sections).
In Gamma 5, webpages with flexible-height sections already have no gap between sections.
To change the spacing inside your slides in Gamma 5, set Density to Compact, Comfortable, or Spacious in your theme's typography settings in Styles, or choose Custom to set an exact Spacing value.
Layouts also have their own Spacing menu (None, Divider, Small, Medium, Large) for the space between their columns or items.
Can I set a custom background for individual slides?
Backgrounds set in Page Setup apply to the entire gamma.
To customize a single slide, click the slide to select it, then use Card background color or Background image in the toolbar at the top of the editor.
In gammas made before Gamma 5, open the Styling (palette) menu at the top-left of the slide and use Background color or Backdrop instead.
Why do my PowerPoint slides have white borders after exporting?
White borders in an exported PPTX are often caused by the Show Slide Backdrops setting being toggled on. When this is enabled, the slide backdrop is included in the export and can create unexpected borders or padding, depending on your background and slide size settings.
To fix this, go to Page Setup (three-dot menu → Page Setup) and toggle Show Slide Backdrops off, then re-export.
