Free Web Accessibility Compliance Guide: WCAG Checks You Can Do Today

Make Your Website Usable by Everyone (It Might Be Legally Required)

TL;DR: Web accessibility isn't optional anymore. WCAG compliance ensures your website works for users with visual, motor, auditory, and cognitive disabilities. Free tools for color contrast checking, readability scoring, and content structuring handle the most common accessibility failures. Most violations are easy to fix once you know where to look.

A client received a demand letter from an accessibility advocacy group. Their ecommerce site violated WCAG 2.1 guidelines in 14 documented ways. The legal costs to respond plus the remediation work exceeded $8,000.

Every single violation could have been prevented with a 30-minute check using free tools before launch. Low-contrast text, missing alt attributes, poor heading hierarchy, and unreadable font sizes. Basic issues with basic fixes.

The Most Common Accessibility Failures (and How to Fix Them)

Color Contrast

Low contrast between text and background is the single most common WCAG violation. The Color Accessibility Checker tests any two colors against WCAG AA and AAA standards instantly.

The standards:

• Normal text: minimum 4.5:1 contrast ratio (AA), 7:1 (AAA)
• Large text (18px+ or 14px+ bold): minimum 3:1 (AA), 4.5:1 (AAA)

I run every color combination through this tool during design. Light gray text on a white background might look elegant, but it fails accessibility and alienates users. More color guidance: Color theory guide.

Readability

Complex language excludes users with cognitive disabilities and non-native speakers. The Readability Scorer analyzes text against multiple grade-level metrics. Target a Flesch Reading Ease score above 60 for public-facing content.

The Grammar Checker catches awkward constructions that impede comprehension. Clear, simple writing is an accessibility feature. Full workflow: Writing tools guide.

Font Size and Typography

Text below 16px on screens strains many users' eyes. The Font Pairing tool helps select readable font combinations with appropriate size hierarchy. Pair with the Accessibility Checker to verify the chosen fonts maintain adequate contrast.

Image Optimization with Alt Text Planning

While Toolgami's tools don't write alt text, the image optimization pipeline ensures images are properly formatted and sized. The Image Compressor and Image Resizer prepare images for fast loading, which benefits users on assistive technology that loads images differently. Guide: Image optimization.

Structured Content

Proper heading hierarchy (H1 → H2 → H3) enables screen readers to navigate page structure. When building content for web, use the HTML Formatter to verify heading structure is clean and logical. The Schema Markup Generator adds structured data that improves both accessibility and SEO.

FAQ

Is WCAG compliance legally required? In many jurisdictions, yes. The EU's European Accessibility Act, the US ADA, and Canada's AODA all require or encourage web accessibility. Requirements vary by region and organization type.

What's the difference between WCAG AA and AAA? AA is the widely accepted minimum standard. AAA is stricter (higher contrast ratios, simpler language). Most legal requirements reference AA. AAA is aspirational for most sites.

Can I make my site fully accessible with just these tools? These tools cover the most common violations: contrast, readability, and content structure. Full compliance also requires keyboard navigation testing, screen reader testing, and semantic HTML review, which need manual testing or specialized tools.

How do I test screen reader compatibility? Use free screen readers like NVDA (Windows) or VoiceOver (Mac). Navigate your site without a mouse to identify barriers. The structured data and heading checks from Toolgami tools ensure the content foundation is solid.

Does accessibility hurt design? No. High-contrast, well-structured, readable designs look more professional, not less. Accessibility constraints often produce cleaner, more user-friendly results.
