I’d like to suggest adding support for viewport-based height (for example 100vh) in Figma Sites.
In many real-world design scenarios, especially for web and responsive layouts, designers need a page or a specific section to always take the full height of the user’s browser viewport. Currently, this requires workarounds with fixed frame sizes or manual resizing, which breaks responsiveness and does not accurately reflect how layouts behave in production.
Tools like Framer and Webflow already support viewport units, making it easy to design hero sections, full-screen onboarding, landing pages that adapt to the user’s screen height. Having a similar option in Figma, such as setting a frame or section height to “Viewport height” or “100vh”, would greatly improve accuracy, responsiveness.
This would be especially useful for:
-
Full-screen landing sections and heroes
-
Onboarding and single section screens
-
More realistic responsive previews without manual resizing
I believe this feature would make Figma Sites even stronger for web and product designers. Thanks for considering it.
