Alt Text and Accessible Metadata for Ebook Cover Images

Published July 6, 2026 — Design Guides

Color contrast and readability get most of the attention in cover accessibility discussions, but a meaningful share of readers with visual impairments experience your cover through a screen reader reading alt text aloud, not through the image at all. If that alt text is empty, or is just the filename, or a generic phrase like "book cover image," those readers get essentially no information about your book's genre or tone from the cover at the exact moment sighted browsers are forming their first impression.

What Alt Text Actually Needs to Convey

Good cover alt text isn't a literal, exhaustive description of every visual element — "a woman in a blue dress standing in front of a castle with clouds in the sky" — it's a description that conveys the same genre and tone signal a sighted reader picks up instantly. Something closer to "Cover of a historical romance novel, featuring a woman in Regency-era dress before a castle at dusk" tells a screen reader user what a sighted browser gleans in under two seconds: genre, setting, era, mood. This distinction between literal description and functional description is the single biggest quality gap in most cover alt text that does exist.

Where Alt Text Actually Lives

  • Retailer product pages generally pull alt text from metadata you supply during upload, not automatically from the image file, so an empty field on your KDP or IngramSpark listing means no alt text reaches the retailer page regardless of what's embedded in the image file itself.
  • Your own author website or blog uses whatever alt attribute is set in the HTML image tag, which is entirely within your control and easy to check by viewing the page source.
  • Social media posts increasingly support manually added alt text on images, a separate field from the caption that gets skipped almost universally by authors posting cover reveals, despite taking under a minute to fill in.

Writing It Once, Reusing It Everywhere

Because the same cover image gets posted to a retailer listing, your own site, and social media, it's worth writing one solid alt text description alongside your cover file itself — treating it as part of the deliverable your designer or you produce at the same time as the final image, not an afterthought filled in separately on each platform under time pressure during launch week. Store it in the same folder as your final cover files so it travels with the asset rather than getting rewritten inconsistently each time.

This Is Distinct From Visual Accessibility

Alt text accessibility and visual accessibility — color contrast, avoiding color-only distinctions covered in our piece on designing for color blindness and low vision — solve different problems for different readers and both matter independently. A cover can have excellent color contrast for low-vision readers who still see the image, while having zero usable alt text for screen reader users who don't see it at all; fixing one doesn't fix the other; both are worth doing and neither is difficult once you know to check for it.

A Practical Starting Reference

The W3C Web Accessibility Initiative publishes a genuinely practical, non-technical guide on writing effective alt text at w3.org/WAI/tips/writing, and its general principles — describe function and content, not exhaustive visual detail, keep it reasonably concise — apply directly to cover images even though the guide isn't book-specific. Running your current cover's alt text (or lack of one) through that framework once is a quick way to catch a small, low-effort accessibility gap that most independent author catalogs currently have across their entire backlist, not just a new release, and it's worth doing across your existing published platform listings retroactively, not just for future covers.

Audiobook Cover Alt Text Has Its Own Wrinkle

Audiobook platforms present a specific case worth calling out separately, since a listener choosing an audiobook is, by definition, often someone who relies more heavily on non-visual information to begin with. A cover's alt text on an audiobook-specific storefront carries a bit more weight proportionally than it does on a print or ebook listing, precisely because the visual cover was never going to be the primary way this particular buyer engaged with the product regardless of vision status. Treating audiobook cover alt text as equally important, not secondary to the ebook or print version's, closes a gap that's easy to overlook when alt text gets filled in once and copied across formats without adjustment.

A Quick Audit Method

If you have more than a handful of titles, a fast way to audit existing alt text across your catalog is to pull up each retailer listing and use your device's own screen reader feature briefly on the cover image area, rather than trying to check the underlying metadata field manually one platform at a time. Hearing exactly what gets read aloud, including an empty or unhelpful description, makes the gap concrete in a way that reading a metadata field in a dashboard often doesn't, and it takes only a few minutes per title once you know where to look.
