Please don't stretch your app for foldables
Stretching mobile UIs for foldables creates broken experiences, as users require responsive, multi-pane layouts that adapt to changing device postures.
What: The article suggests that developers should stop treating foldables as simple screen-size scaling exercises and instead implement responsive patterns that support various hinge states and postures.
Why it matters: The industry is moving past the 'mobile-first' era into a 'responsive-everything' era where software must handle fluid windowing environments across phones, tablets, and desktop OS shells.
Takeaway: Adopt multi-pane layout strategies that maintain user context when a device unfolds, rather than just increasing element padding or width.
Deep dive
- Mobile layouts do not scale gracefully when simply stretched across large, unfolded screens.
- Multi-pane UI patterns (e.g., list-detail views) are essential for utilizing the extra screen real estate provided by foldables.
- Design should focus on fluid container constraints rather than hard-coded device breakpoints.
- Hinge-aware design allows for split-screen utility during specific postures like 'tabletop' mode.
- Platform guidelines like Material Design provide specific patterns for hinge-awareness that developers should follow.
Decoder
- Hinge-aware: Design patterns that account for the physical fold in a display, allowing the software to avoid placing interactive elements in the crease or split content across it.
- Multi-pane: A UI pattern where an application displays multiple functional areas simultaneously, often seen in mail or file explorer apps on tablets.
Original article
Foldable devices require apps to adapt to changing screen sizes, orientations, and postures with responsive layouts, multi-pane interfaces, and hinge-aware designs that preserve context and usability instead of simply stretching existing mobile UIs. By designing around available space rather than specific devices, teams can create experiences that work consistently across phones, foldables, tablets, and desktop-sized windows while following platform-specific layout conventions.
