#FAQ
How long should alt text be? ▾
Alt text should generally be concise, ideally under 125 characters. Screen readers may truncate longer text. For complex images like charts, use a brief alt attribute and provide a longer description elsewhere on the page.
When should I use an empty alt attribute? ▾
Use an empty alt attribute (alt="") for purely decorative images that add no informational content, such as background patterns or visual separators. This tells screen readers to skip the image entirely.
