UX/UI 101: Differences between Low & High Fidelity

April 19, 2022

During the design & discovery phases of a new development project, you may encounter a couple of new terms.


  • Low Fidelity or LoFi
  • High Fidelity or HiFi

As UX / UI designers, we use these terms to introduce concepts at the beginning, middle, and end of our work.

For clarity, let’s dive into the individual stages and discover how we utilize them here at fjorge.

Low Fidelity:

Low Fidelity wireframes, known more commonly as LoFi, are conceptual designs used at the early stages of design & discovery to convey user interaction and a simple visual depiction of the layout of the website or application.

LoFi wireframes are often less complex and don’t require any color, selected fonts, or imagery. They are typically “rough” visually and require less effort to create. Whether the LoFi wireframes are drafted on a piece of paper or developed using design software like Figma, they will allow us designers and the client to quickly align on the direction of the project and make it easier to revise before moving on to High Fidelity Designs.

Example of Low Fidelity Designs

High Fidelity:

LoFi wireframes approved by the client are then reworked into High Fidelity designs, abbreviated as HiFi. In order to provide the client with a clear indication of aesthetics, usability, and responsiveness, HiFi designs utilize pixel-perfect design elements & client branding. HiFi designs represent what the final product will look like before it enters front & backend development.
