Accessibility checking, in the context of Figma, refers to the process of evaluating a static design file for issues that will affect users with disabilities once that design becomes a real product — color contrast ratios below WCAG thresholds, text sizes that fail minimum legibility standards, missing semantic structure that screen readers depend on, and interactive elements without a clear focus state. Plugins built for this purpose surface those issues at the design stage, before a single line of production code exists to fix.
That timing matters more than it might seem to at first glance. A contrast failure caught in Figma costs a color swap. The same failure caught in a post-launch audit costs a ticket, a sprint slot, a code review, and a deploy. Below is a ranked comparison of the five plugin categories that do the most work toward closing that gap, ordered by how broadly useful each one is across a typical design workflow.
1. Stark
Stark sits at the top of this list because it covers the widest range of accessibility checks in a single tool: contrast ratio analysis against WCAG AA and AAA thresholds, a vision simulator that previews designs under various forms of color blindness, and a focus-order review feature that flags interactive elements likely to confuse screen reader navigation. Few single plugins attempt this much breadth without sacrificing depth in any one area.
Strengths: Broad checklist coverage means one plugin often satisfies most of a team’s baseline accessibility review needs without stacking multiple tools together.
Limitations: Because it tries to cover so much ground, some individual checks are less granular than a category-specific tool would provide. Teams with highly specialized accessibility requirements — medical interfaces subject to stricter regulatory standards, for instance — may need to supplement it.
Best for: Teams establishing a baseline accessibility review process who want one plugin that handles the majority of common checks without requiring several separate tools.
2. Contrast Checker Plugins (A11y Color Contrast Checker and Similar Tools)
Dedicated contrast-checking plugins do one thing, and they do it with more precision than a broader tool typically offers: they take a foreground and background color pair, calculate the exact contrast ratio, and tell you immediately whether it clears AA or AAA thresholds for the text size in question. Some versions of these plugins scan an entire frame at once and flag every failing pair automatically, rather than requiring a manual click-through of each element.
Contrast failures are, by a wide margin, the most common accessibility issue found in production interfaces — light gray text on white backgrounds, low-contrast placeholder text, disabled-state buttons that fail contrast even though they’re intentionally muted. A dedicated checker catches these reliably because contrast calculation is its entire purpose, not one feature among many.
Best for: Any project where text-and-background color pairings need verification, which in practice means nearly every design file. This category earns a place in most designers’ regular toolkits regardless of what other accessibility plugins they use.
3. Color Blindness Simulators
Simulator plugins render a frame or selection as it would appear to someone with protanopia, deuteranopia, tritanopia, or full achromatopsia. Roughly 1 in 12 men and 1 in 200 women experience some form of color vision deficiency, which makes this check relevant to a meaningful share of any user base — not an edge case reserved for specialized accessibility audits.
The practical value shows up most clearly in designs that rely on color alone to convey meaning: red-versus-green status indicators, chart legends distinguished only by hue, or error states signaled purely through a color shift with no accompanying icon or text label. Running a design through a simulator surfaces these problems immediately, in a way that reviewing the standard color palette in isolation never will.
Best for: Data visualization work, status indicators, and any design where color functions as the primary or sole carrier of meaning rather than as decoration layered on top of text or iconography.
4. Text Resize and Legibility Checkers
This category checks whether text remains legible and layouts remain intact when font sizes scale up, which matters because a meaningful portion of users browse with system-level text scaling enabled to accommodate low vision. Plugins in this space flag text set below recommended minimum sizes and, in some cases, simulate how a layout holds up when text is scaled 150% or 200% beyond its base size.
Layouts that look clean at a designer’s default zoom level can break down considerably once text scaling is factored in — labels truncate, buttons overflow their containers, spacing that depended on short text suddenly doesn’t. Catching this at the design stage is far cheaper than catching it after a user support ticket reports broken UI at their preferred text size.
Best for: Designs with substantial body text or dense information density, where legibility at non-default text sizes has a direct, outsized effect on usability for a portion of the eventual user base.
5. Screen Reader Structure and Alt Text Annotation Tools
The final category addresses a layer of accessibility that visual checking alone can’t touch: the semantic structure and text alternatives that screen readers rely on to navigate and interpret a design. These plugins let designers annotate frames with intended heading levels, alt text for images, and reading order — information that doesn’t exist anywhere in a standard Figma layer structure by default but that developers need in order to build an accessible product.
This category ranks last on this list not because it matters less, but because it addresses a different stage of the workflow: closer to handoff than to in-progress design review. Its value is real and often underestimated, since structural accessibility issues are among the hardest and most expensive to retrofit after development is complete.
Best for: Design handoff and developer collaboration, particularly on projects where the design and development teams are separate and semantic intent needs to be communicated explicitly rather than assumed.
How These Five Categories Work Together
None of these plugins fully substitutes for another; each one addresses a distinct failure mode. A design can pass every contrast check Stark offers and still fail a color-blind user relying on hue alone to read a status chart. It can pass a color-blindness simulation and still break down completely once a user scales their system text to 200%. Comprehensive accessibility coverage in Figma tends to come from combining categories rather than treating any single plugin as sufficient on its own.
| Rank | Plugin/Category | Primary Check | Best Applied At |
|---|---|---|---|
| 1 | Stark | Broad multi-check coverage | Ongoing baseline review |
| 2 | Contrast Checker plugins | Precise WCAG contrast ratios | Any text/background pairing |
| 3 | Color Blindness Simulators | Color vision deficiency preview | Data viz, status indicators |
| 4 | Text Resize/Legibility Checkers | Scaled-text layout integrity | Text-dense layouts |
| 5 | Screen Reader Structure/Alt Text Tools | Semantic structure and alt text | Design handoff |
A reasonable working process runs contrast and simulation checks continuously during design, and reserves the structural annotation pass for shortly before handoff, once layouts and copy have stabilized enough that reading order and alt text won’t need to be redone from scratch.
Where to Start If You’re Adding Accessibility Checks for the First Time
Teams with no existing accessibility review process gain the most, fastest, from starting with contrast checking and Stark’s broader baseline coverage — these catch the highest volume of common issues relative to the setup effort required. Color blindness simulation and text resize checking are worth layering in next, particularly for data-heavy or text-dense products where those specific failure modes carry more weight. Structural annotation tools tend to earn their place last, once a team has a handoff process mature enough to make use of the information they generate.
Which of these five categories is missing from your current design process, and does your product’s specific content — heavy in data visualization, text density, or complex interaction states — suggest one category should be prioritized ahead of the others?
