Alt text for event flyers: when the date, time, and place are in the image

If the date, time, and location of your event exist only inside a flyer image, the alt text has to carry them. Write the event name, when, where, and how to sign up, in that order, and leave out the fonts, colors, and decoration. Then a person using a screen reader gets what everyone else gets from a glance: the facts they need to show up.

Put the same details in the post text or the page around the image, too. Real text can be searched, copied, translated, and resized; a picture of text cannot. The W3C’s tutorial on images of text prefers real text styled with CSS, and says that when you do use an image of text, the text alternative should contain the same text the image shows. WCAG’s images-of-text criterion (Level AA) asks for real text where the technology can produce the same look, with exceptions such as logotypes. (If you are new to all this, start with why alt text matters.)

What goes in the alt text for a flyer?

Treat it like the event listing. Name the event, then the date, start and end time, venue, and the one action you want, such as registering or showing up. If the flyer names a speaker, a price, or an RSVP deadline, include it.

The strong version runs past 125 characters, and that is fine here, because the text is the point of the image. The 125-character rule explains when to break it.

What should you leave out?

Anything that is only styling. The W3C says the text alternative for an informative image should convey the meaning of what is shown, which typically is not a literal description, and that a detailed literal description is needed only when the image’s content is the information being conveyed. A flyer is that case for its words, but not for its balloons. Mention a photo or illustration only if it tells the reader something the text does not, like a speaker’s name under a portrait.

For a poster crowded with copy, give the essentials in the alt text and put the full wording in the caption or on the event page. Our guide to text-heavy graphics covers how to decide what to keep. If the flyer includes a venue map, see alt text for maps and floor plans.

Check the details every time

The costly mistake is a mismatch: the image says 6 p.m., the caption says 7. Read the alt text, the caption, and the event page side by side before you post. If the date changes, you will be replacing the image anyway, so update the alt text with it, not just the caption.

A quick workflow: screenshot the flyer, run SnipAlt with Ctrl+Shift+A (⌘⇧A on a Mac), then check every date, time, and address in the draft against your event page before pasting it in. An alt text with a wrong digit is worse than a short one. This is general accessibility guidance, not legal advice, but it takes a minute and it means more people can actually find your event.
