Responsive Media Sizing for Mobile, Desktop & Web Flutter Ads
Learn how to control ad media sizing using flexible layout constraints for responsive Flutter applications across mobile, web, desktop, and tablet devices.
Flutter Media Sizing Guide
Media sizing determines how ads adapt within your Flutter layouts. Proper sizing improves responsiveness, layout stability, visibility, and monetization performance.
Layout & Rendering
Responsive media sizing behavior
Flutter Ads SDK provides flexible height constraints to help ads render correctly across different screen sizes, containers, feeds, and responsive layouts.
Expanded Height
Expands media to fill available vertical space inside parent constraints. Best for feeds and adaptive layouts.
main.dart
ExpandedHeightConstraint()Fixed Height
Locks media to a fixed height for consistent layouts and predictable rendering behavior.
main.dart
FixedHeightConstraint(400)Max Height
Allows media to scale naturally while limiting maximum height for balanced responsive layouts.
main.dart
MaxHeightConstraint(400)Choosing the right constraint
- • Expanded → flexible responsive layouts
- • Fixed → strict consistent sizing
- • MaxHeight → balanced responsive scaling
