Prototyping Fidelity: Low-Fi vs. High-Fi and When to Use Each

Level: Intermediate

Choosing the right level of prototype detail for a given stage of a project meaningfully affects both the speed of iteration and the quality of feedback you receive.

Low-Fidelity Prototypes Encourage Broader, Structural Feedback

A rough, low-detail prototype invites feedback on flow and structure, since reviewers aren't distracted by visual polish that isn't finished yet.

High-Fidelity Prototypes Are Better for Detailed Usability Testing

Once structure is validated, a polished, realistic prototype produces more accurate usability testing results, since it closely resembles what a finished product will actually feel like.

Match Fidelity to the Actual Stage and Question at Hand

Building high-fidelity detail before structural questions are resolved often wastes effort on a design that still needs significant structural revision.
