Mobile app wireframe

Mobile screens have constraints a desktop wireframe lets you ignore: the frame is small, the thumb reaches only part of it, and the navigation pattern is usually fixed by the platform.

Drawing inside a device frame makes those constraints visible rather than theoretical.


#When to reach for one

  • Designing a mobile screen or flow.

  • Reviewing whether a screen fits above the fold on a small device.

  • Documenting platform navigation patterns for a team new to mobile.

Rough exploration before committing to a layout.


#What to include

  • Status bar, navigation bar and any tab bar, at real proportions.

  • The fold: what is visible without scrolling.

  • Every interactive element, sized as a real touch target.

  • The empty, loading and error states, not just the happy one.


#A few things that catch people out

  • Draw the frame at a real device size. "It will fit" is where most mobile designs go wrong.

  • Show the navigation bar and safe areas; they take more space than people remember.

  • Touch targets have a minimum size. A wireframe that ignores it hides a real problem.



Fidelity is a choice, so choose it.
