Designers spend enormous energy shaping the visual layer of a product—colors, spacing, typography, interactions. But for millions of users, the experience of your interface isn’t visual at all. It’s spoken aloud by a screen reader, navigated through a keyboard, or interpreted by assistive technologies.
The challenge? Many of the decisions that shape that experience aren’t visible on the screen. And when those decisions are not communicated, they get lost somewhere between design and engineering.
This is exactly why accessibility annotations are becoming an essential—and increasingly standard—part of UI and UX design.
What Are Accessibility Annotations?
Accessibility annotations are structured notes added to design files (often in tools like Figma) that specify how an interface should behave for users with disabilities. They document critical details that sighted users may never notice—but that assistive technology users depend on.
These annotations include things like:
- Which heading level a title should use
- Whether an icon is decorative or needs alt text
- The order a screen reader should navigate content
- Keyboard interactions and shortcuts
- Landmark regions and semantic roles
- How components announce changes
- Focus order and focus management
Put simply: annotations give engineers the information they can’t see in the mockup.
Why They Matter
Design files only show one version of the truth: the visual one. But many accessibility requirements are invisible and therefore easy to overlook.
Accessibility annotations help bridge that gap by ensuring:
1. The intended experience is fully communicated.
Designers define not just how a page looks, but how it’s experienced by all users—including those who hear it rather than see it.
2. Engineers don’t have to guess.
Ambiguity causes accessibility bugs. Annotations prevent assumptions and reduce back-and-forth during implementation.
3. Accessibility is built into the design process.
Government systems like the U.S. Veteran Affairs Design System now require annotations as a standard practice, pushing accessibility upstream into design rather than treating it as a post-development patch.
4. Quality and consistency improve.
Clear documentation means predictable components, smoother handoffs, and fewer regressions.
Accessibility can no longer be an afterthought, and annotations make it sustainable.
What This Looks Like in Practice
Imagine an alert banner that contains:
- A heading
- An informational icon
- Descriptive text
Visually, it’s clear enough. But assistive technologies need semantic clarity. Through annotations, a designer might specify:
- “This heading should be an H3.”
- “The icon is decorative; do not provide alt text.”
- “Alert uses
role="alert"to trigger announcement.”
These details define how the component behaves for a screen reader user—and no amount of pixel-perfect layout communicates that on its own.
Whose Job Is It?
Accessibility is a team effort.
But annotations begin with design.
- Designers create annotations that convey intent.
- Engineers implement the semantics and behaviors.
- Testers/QA verify annotations were correctly interpreted.
When each role follows through, accessibility becomes intentional rather than accidental.
A Practical Checklist for Designers
Use this checklist during component creation, reviews, or developer handoff.
Structure & Semantics
- Have you defined heading levels (H1–H6)?
- Are landmark regions documented (main, nav, header, footer, aside)?
- Are element roles specified (button, link, alert, tab, switch)?
Images & Icons
- Does each image have meaningful alt text—or is it intentionally marked decorative?
- Are status or informational icons labeled appropriately?
Reading & Focus Order
- Is the reading order clear and annotated?
- Is the keyboard focus order documented?
- For modals/drawers, is focus management specified?
Interactions & Behaviors
- Are relevant keyboard interactions or shortcuts defined?
- Are dynamic updates paired with announcements (e.g., success/error messages)?
- Are component states (error, disabled, active) described?
General Communication
- Have you annotated any assumptions not visible in the mockup?
- Have you used consistent annotation formatting throughout the file?
- Would an engineer understand the full non-visual experience from your notes alone?
Final Thoughts
Accessibility annotations aren’t extra—they’re essential. They articulate the hidden parts of design, giving engineers the information they need to build experiences that work for everyone. When used consistently, annotations transform accessibility from a compliance task into a core part of the design craft.
If we want digital products to be inclusive, annotations are how we get there.
