# Usability vs. Accessibility: What They Mean in Web Design

[ Accessibility Glossary ](https://nitsantech.de/en/accessibility-glossary)usability-vs-accessibility
==========================

 [

  Usability  ](https://nitsantech.de/en/accessibility-glossary/usability) [

  User Testing  ](https://nitsantech.de/en/accessibility-glossary/user-testing)

 While both **usability** and **accessibility** are critical for designing inclusive digital services, they focus on slightly different goals:

- **Usability** refers to how easily and effectively all users, regardless of ability, can use a product or interface.
- **Accessibility** focuses specifically on ensuring that people with disabilities can perceive, understand, navigate, and interact with content.

**How They Intersect**

A product can be usable but not accessible, and vice versa. For instance:

- A website might have intuitive navigation (good usability) but lack [**Screen reader**](https://nitsantech.de/en/accessibility-glossary/screen-readers) support (poor accessibility).
- Alternatively, it might technically meet [**accessibility standards**](https://nitsantech.de/en/blog/accessible-website-checklist) (e.g., correct semantic HTML), but still confuse users due to poor layout (bad usability).

**Why Both Matter**

In truly inclusive design, both aspects must be considered. Accessibility ensures legal and ethical compliance, while usability enhances overall user satisfaction and effectiveness for everyone.
