Instant WCAG Compliance Checklist | Free Accessibility Guide

WCAG Compliance Checklist

All 78 success criteria from WCAG 2.1 in one interactive wcag compliance checklist, grouped by principle and explained in a sentence of plain English each. Filter to the conformance level you actually target: the default view shows Level A and AA, the combination most laws require, and one click adds AAA. Teams reach for a wcag 2.1 checklist like this when an audit, a procurement questionnaire, or a legal deadline suddenly demands proof of review and the spec itself is too dense to hand to a designer. Tick criteria as you verify them, watch the counter update, and export the whole accessibility success criteria list when someone upstream asks what's been covered.

How to use

Set the levels you need

Use the A, AA, and AAA buttons above the list to filter. The default shows A and AA together, which is the target named by ADA Title II, Section 508, and the European Accessibility Act.

Verify criteria one by one

Each item shows its number, name, level tag, and a plain-English test, like 1.4.3 requiring 4.5:1 text contrast. Check items off as you confirm them; progress saves in your browser.

Export your progress

Copy the checklist as Markdown for your issue tracker or download it as CSV for stakeholders, so the verification work you did becomes a document someone else can read.

Common questions

How many items does the wcag compliance checklist include?

All 78 success criteria from WCAG 2.1, organized under the spec's four principles. The counter next to the filter buttons shows how many criteria your current level selection displays.

Does a wcag aa checklist automatically include Level A items?

Yes, and it has to. Claiming AA conformance requires meeting every Level A criterion as well, which is why the default filter here shows both levels together rather than AA alone.

What do the four principle groups in the checklist mean?

They're WCAG's own structure: content must be perceivable, interfaces must be operable, information must be understandable, and markup must expose name, role, and state to assistive technology. Grouping criteria this way makes it easier to assign sections to the right specialist.

Why does criterion 4.1.1 Parsing carry an obsolete note?

WCAG 2.2 removed 4.1.1, but it remains part of WCAG 2.1, which is the version current legislation cites. Audits still reference it, so the checklist keeps it with a note rather than dropping it.

Can I use this wcag 2.1 checklist on a WCAG 2.2 project?

Mostly, yes. WCAG 2.2 keeps every 2.1 criterion except 4.1.1 and adds nine new ones, so this list covers the shared core. For legal work, 2.1 is still the standard ADA Title II and most current laws name.

Is ticking every checklist box the same as WCAG conformance?

No. The checklist tracks your verification work; it can't perform the verification for you. Several criteria, like keyboard traps or captions quality, only reveal themselves through real testing with a keyboard and a screen reader.

Where does the accessibility success criteria list keep my progress?

In your browser's local storage, tied to this site. Clearing site data wipes it, so export a Markdown or CSV copy before cleaning up your browser or moving to another machine.
