What do I do when an alt text field is too small for my description?
According to WCAG Success Criterion 1.1.1 (Non-Text Content), you must provide an equivalent text alternative for all non-text content. However, this does not have to exclusively be provided through the alt text field.
A solution would be to provide a transcript of the document text and include it on the page under a disclosure button.
