Level AA represents the standard that creates genuinely usable digital experiences for most people. While Level A prevents complete barriers, Level AA makes products comfortable and practical to use for a wide range of users. It's the level most organizations need to meet for legal compliance and real-world accessibility.

You can consider contrast requirements as an example of Level AA's impact. While users might technically be able to read low-contrast text, it creates unnecessary strain and frustration. Level AA's contrast requirements (4.5:1 for normal text) ensure comfortable readability across different vision capabilities and lighting conditions.

Meeting Level AA shows a serious commitment to accessibility while remaining achievable for most digital products.
