Developers should use rem units when building responsive web designs that need to adapt to various devices and user font-size settings, as they ensure consistent spacing and sizing based on a single root value meets developers should learn and use viewport units when building responsive web applications that need to maintain consistent proportions across various screen sizes, such as full-screen hero sections, modals, or typography that scales with the viewport. Here's our take.

rem
Nice PickDevelopers should use rem units when building responsive web designs that need to adapt to various devices and user font-size settings, as they ensure consistent spacing and sizing based on a single root value
Pros
- +They are particularly useful for accessibility, allowing users to adjust browser font sizes without breaking layouts, and for maintaining design systems where components scale predictably across the entire application
- +Related to: css, responsive-design
Cons
- -Specific tradeoffs depend on your use case
Viewport Units
Developers should learn and use viewport units when building responsive web applications that need to maintain consistent proportions across various screen sizes, such as full-screen hero sections, modals, or typography that scales with the viewport
Pros
- +They are particularly useful for mobile-first design, ensuring elements like buttons or containers resize appropriately without complex media queries, and for creating immersive experiences like landing pages that fill the entire screen regardless of device
- +Related to: css, responsive-design
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use rem if: You want they are particularly useful for accessibility, allowing users to adjust browser font sizes without breaking layouts, and for maintaining design systems where components scale predictably across the entire application and can live with specific tradeoffs depend on your use case.
Use Viewport Units if: You prioritize they are particularly useful for mobile-first design, ensuring elements like buttons or containers resize appropriately without complex media queries, and for creating immersive experiences like landing pages that fill the entire screen regardless of device over what rem offers.
