Design Handoff Best Practices
Part of the UI/UX Design Roadmap
In short
A handoff isn't 'here's the Figma link, bye'. It's everything an engineer needs to build the design without guessing: sizes, states, flows, edge cases and the reasons behind them.
Going beyond Phase 5's basics — organizing a file for handoff means clear component naming, documented states, exported assets, and often a short walkthrough conversation with the engineering team.
Think of it like this
Handing over a house key
When you rent out your flat, you don't just hand over the key. You show where the meter is, which switch runs the geyser, and the plumber's number. A good handoff is the full house tour, not just the key.
Watch it happen
What a complete handoff includes
1/4User flows: how screens connect, including back buttons and what happens after success.
The big ideas
What you need to know
Mark what's ready
Separate 'ready for dev' frames from explorations, using sections or a status label.
Use the system
Components and tokens in the design map directly to code. Detached layers create confusion.
Walk them through
A short live walkthrough or recorded video explains intent better than a pile of comments.
Stay reachable
Handoff is the start of a conversation. Answer questions quickly during the build.
Save yourself the pain
Common mistakes
Oops
Leaving old explorations mixed in with final screens.
Do this instead
Move finished work to a clear 'Ready for dev' page and archive the rest.
Oops
Designing only the ideal state.
Do this instead
Include empty, loading, error and long-content versions for every important screen.
Your mission
Prepare a real handoff
Quick check
An engineer builds a list screen and it shows a blank white area when there's no data. What was most likely missing from the handoff?
Go deeper
- 1Prepare a full file for handoff: clean layers, documented states, exported assets.
- 2Practice walking an engineer (or a peer standing in) through a design's intended behavior.
- 3Learn to flag known open questions or edge cases explicitly rather than leaving them ambiguous.
