WAVE Error

Long alternative text

What It Means

An image has very long alternative text.

Why It Matters

Alternative text should be succinct, yet descriptive of the content and function of an image. Lengthy alternative text (more than around 100 characters) often indicates that extraneous content or content that is not available to sighted users is being presented.

What To Do

Ensure the alternative text is succinct, yet descriptive. Ensure that no content is being presented in alternative text that is not available to sighted users viewing the image. When possible, either shorten the alternative text or provide the text alternative via another method (e.g., in text near the image, through a separate description page, etc.).

The Algorithm... in English

The image's alt attribute value is more than 100 characters. Note that the 100 character limit is a rough and somewhat arbitrary length. For images that present complex content or lengthy text, alternative text longer than 100 characters may be appropriate.
