Designing Accessible Graphics & Slides in Canva Training Recap

Why Accessible Canva Design Matters

Canva produces visually rich content, but visual presentation alone excludes a significant portion of your audience. Users who are blind or have low vision rely on screen readers and refreshable braille displays to engage with digital content. Users with cognitive or learning disabilities may depend on reading mode tools, focus modes, or text-to-speech. Users with color vision deficiencies—approximately 10% of the male population—use high-contrast modes and color filters. Users with limited motor control may rely on keyboard navigation rather than a mouse.

When content is designed without accessibility in mind, these users encounter slides read aloud in the wrong order, graphics announced as "image" with no further information, text that is too small or too low-contrast to read, and static images that cannot be zoomed or reflowed without excessive horizontal scrolling. The training opened with a live screen reader demonstration of an inaccessible Canva template. The experience illustrated how quickly decorative elements, out-of-order layers, and missing alt text combine to make a presentation incomprehensible to someone depending on assistive technology.

Common Accessibility Issues in Canva Designs

The training identified four categories of issues that appear frequently in Canva templates and user-created designs. Understanding these issues is the starting point for fixing them.

Missing or unnecessary alt text. When a meaningful image has no alt text, screen reader users hear only "image" or the file name, with no context about what the image communicates or what action it prompts. When decorative elements have no designation, the screen reader reads them all sequentially, creating a disruptive wall of noise before reaching the actual content. Both conditions need to be addressed.

Low color contrast. Canva's default templates frequently include color combinations that fail WCAG contrast requirements. Red-on-black, light gray text on white backgrounds, and text placed directly over photographic images are common failure patterns. The football graphic example shown during the training—red and black text over a complex background—appeared nearly illegible when simulated for someone with total colorblindness.

Small text size. Many Canva templates use very small body text as a design choice. For body content that users are expected to read, 16px is the recommended minimum. Text that is small and low-contrast compounds the readability problem significantly.

Reading order errors. Canva renders slides visually in a way that may have no relationship to the order content was added or how layers are stacked. Screen readers follow the layer order, not the visual position. Out-of-order layer stacking can cause a screen reader to announce solution headings before the section title, or read body content before the heading it belongs to.

Best Practices: The POUR Principles Applied to Canva

The training organized best practices around the WCAG POUR framework: Perceivable, Operable, Understandable, and Robust.

Perceivable means your content can be accessed through more than one sense. For Canva, this means providing text alternatives for meaningful images, icons, and charts; avoiding images of text where actual text would serve the same purpose; ensuring 4.5:1 color contrast for body text and 3:1 for large-scale headings; using readable typefaces (avoid decorative or script fonts set in all caps for body content); and ensuring that body text is at least 16px.

Operable means users can navigate and interact with your content through different means. For presentations, this means using structural headings so screen reader users can jump between sections, and using descriptive link text rather than bare URLs or "click here" phrases that provide no context when read out of sequence.

Understandable means content is clear and predictable. Avoid excessive visual clutter and keep layouts consistent. The same principle applies to slide transitions and animations: flying text, word-by-word reveals, and heavy motion effects are disorienting for many users, including those with vestibular disorders. A simple fade between slides is sufficient.

Robust means your content remains accessible as users zoom or change display settings. Static images with embedded text cannot reflow when a user zooms to 400%—they must scroll horizontally to follow each line. Wherever possible, use actual text in Canva rather than text embedded in graphics.

Using Canva's Built-In Accessibility Tools

All of Canva's accessibility features are accessed through the File menu. Go to File > Accessibility to access the following tools.

Check Design Accessibility. This runs an automated scan of your current design for color contrast failures and missing alt text. Note that the checker can take a moment to render results, particularly if your connection is slow—if it reports everything passing immediately, click again and give it a few seconds to complete the scan. When issues are found, the checker highlights the affected element and offers a suggested fix for contrast failures. Clicking "Apply suggested text color" corrects the flagged contrast issue. You can also verify contrast independently using the Silktide browser extension, which is available to all TTU account holders.

Alternative Text. Also under File > Accessibility, this panel lists every element in your design that does not have alt text assigned. For each element, you have two choices: mark it as decorative (the screen reader will skip it entirely) or write descriptive alt text. Elements that do not contribute to understanding the content—background shapes, dividers, decorative icons—should be marked decorative. Elements that communicate meaning, support a call to action, or contain information a reader would otherwise miss need specific, descriptive alt text. Context matters: the same chart image would have different alt text on a department homepage versus an internal data report.

Edit Text Semantics. Also under File > Accessibility, this panel allows you to designate text elements as Heading 1, Heading 2, Heading 3, or Paragraph. Applying heading roles to your slide titles and section headers allows screen reader users to navigate by heading rather than listening to every word on every slide. Without semantic markup, all text is treated as equivalent body content.

Reading Order via Position > Layers. Open the layers panel through the Position menu or the Arrange tab. The order in which a screen reader announces content corresponds to the stacking order of layers—with the important caveat that Canva reads from the bottom of the layers list upward. To have your slide title read first, it should appear at the bottom of the layers list. Drag layers to arrange them in the intended reading sequence.

Exporting Accessible Files from Canva

Exporting as PDF. After running the accessibility checker and addressing the issues it finds, export via Share > Download > PDF Standard. Before clicking Download, uncheck the "Flatten PDF" option. Flattening discards all accessibility structure and converts your content into a single image layer, which is completely inaccessible to screen readers. Once you have the PDF, open it in the full Adobe Acrobat application (not Reader) and run the built-in accessibility checker. Acrobat will always prompt you to manually verify reading order and color contrast—this is expected behavior, not an indication that those items failed. Acrobat cannot verify reading order or contrast automatically; it is asking you to confirm that you have addressed them. Use Acrobat's Read Aloud function as a final check to hear your document in sequence.

Exporting as an image. When you export a Canva design as a PNG, JPG, or other image format, all alt text and structural information from Canva is lost. You must re-enter alt text in whatever platform you are posting to: Instagram, Facebook, Canvas, Word, and other platforms all have their own alt text fields, and none of them receive the metadata from Canva on export. If you are posting a graphic to social media, add alt text through the platform's native accessibility options after uploading.

Embedding or linking directly to Canva. Sharing a Canva presentation via its native link or embedding it through an iframe will retain the alt text and structural information you added inside Canva. However, this approach may not render correctly on all platforms, and it is not feasible for social media posts. PDF export is generally more reliable for sharing accessible content across contexts.
