# 2.5.5 Target Size (Enhanced)

- Level: AAA
- Guideline: 2.5 Input Modalities
- Principle: 2 Operable

## What it is

The size of the target for pointer inputs is at least 44 by 44 CSS pixels except when:

- **Equivalent:** The target is available through an equivalent link or control on the same page that is at least 44 by 44 CSS pixels;
- **Inline:** The target is in a sentence or block of text;
- **User Agent Control:** The size of the target is determined by the user agent and is not modified by the author;
- **Essential:** A particular presentation of the target is essential to the information being conveyed.

## How to test

- Check: The target is available through an equivalent link or control on the same page that is at least 44 by 44 CSS pixels;
- Check: The target is in a sentence or block of text;
- Check: The size of the target is determined by the user agent and is not modified by the author;
- Check: A particular presentation of the target is essential to the information being conveyed.
- Use the sufficient techniques below as acceptable methods when applicable.
- Confirm none of the common failures apply.

## Sufficient techniques (W3C)

- Ensuring that targets are at least 44 by 44 CSS pixels

## Advisory techniques (W3C)

- Ensuring inline links provide sufficiently large activation target

## Common failures (W3C)
