Responsive design breakpoint matrix’s in UX

UX/ UI Designer

In today’s digital landscape, ensuring a seamless user experience across all devices and viewport sizes has become vital when creating digital products. With the rise of smartphones and tablets, as well as the ever-present laptop and desktop, users interact with a variety of screen sizes and resolutions. This is where responsive design comes into play, when creating a responsive design, UX designers must consider breakpoints, layouts and grid sizes. A breakpoint matrix can act as an invaluable tool to achieve seamless and harmonious responsive designs and user experiences across all viewport sizes, big and small.


What is a breakpoint matrix?

A breakpoint matrix is a visual representation of how a website or app’s design responds to various screen sizes and orientations. It can take various forms but is essentially a grid or page layout that describes the way pages behave at different breakpoints. Each cell or section represents a different screen width and provides an explanation of the design, structure and layout of the page. Designers can, therefore, visually showcase how the designs differ across viewport sizes.

Components of a breakpoint matrix

Breakpoint values

These are the specific pixel values at which breakpoints are triggered and are defined by traditional viewport sizes. Common breakpoints include:

  • Small (mobile) 360px 
  • Medium (Tablet portrait) 768px 
  • Large (Tablet horizontal or laptop) 1024px
  • Extra large (desktop) 1920px


Layout adjustments

In each matrix cell, designers specify how the design elements, such as navigation menus, images, and content grids, should rearrange themselves to fit the available space. This can involve changing the number of columns in a grid, altering font sizes, or repositioning key elements.


Visual styling

The matrix also includes notes on any visual styling changes that occur at certain breakpoints. This might involve adjusting colours, backgrounds, or spacing to ensure the design remains visually appealing and easy to navigate.


Interactive elements

Interaction elements, such as form fields and links, may need to be resized or repositioned to accommodate different screen sizes. These can also be outlined and shown visually on the matrix.

Benefits of breakpoint matrixes in UX


Breakpoint matrixes ensure a consistent user experience by providing clear descriptions and principles for how designs should respond to different devices and viewport sizes. Sophisticated responsive design enhances brand recognition and user trust.



Work can be undertaken more efficiently by referring to a predefined matrix where design guides and principles are outlined. This will help save time that would otherwise be spent making design decisions at each breakpoint/device size.



Breakpoint matrixes act as a visual communication tool, allowing designers, developers and key stakeholders to view designs and visualise how they will adapt over various breakpoints, as well as providing some context around design decisions.



Once the website or platform has been built, either as a beta site or live, the designs can be checked against the breakpoint matrix. Discrepancies or mistakes in the product can be easily discovered by comparing the design against the matrix across all viewport sizes.



With the introduction of new devices, screen sizes and resolutions, the matrix can be easily updated to accommodate these changes.



In a world of responsive design, the breakpoint matrix is a tool designers can use to help create exceptional and seamless user experiences across multiple devices. By creating considered designs for the four key viewport sizes (Extra large, large, medium and small) and providing additional context as to how the designs react across each viewport regarding layouts, components, elements and interactions, designers can ensure that the digital products they have created adapt seamlessly across all devices and create exceptional user experiences.
