This letter rests on 71% of the grade. Readability was measured but is not scored here. We have not measured an article for this site. Homepages, listings and other non-article pages can make our typography measurements reflect navigation rather than prose. The numbers are below; the letter leaves them out until we have measured an article. How this is worked out.

Observed interruptions
Ad and tracker counts above are network requests, not counts of visible ads or separate companies. They do not affect the interruption score.
Assessed 3 sampled pages. The largest detected ad area was 0% of a sampled viewport. Verified prompts: Cookie dialog blocks the page, but you can refuse.
This is a sample, not a promise that the whole site has no interruptions. Ad detection can miss formats and content outside the sampled view. Older scans did not check visibility or overlapping ad rectangles as thoroughly. The score uses the strongest observed deduction, so one panel is not penalized under multiple names. How interruptions are scored.
The type, and who can use it
Measured on 1 rendered page; latest measurement 2026-09-10 — no article measured yet. Every number is a mechanical fact about the page, not a judgment of its design.
| What | Measured | The bar |
|---|---|---|
| Body type size | 15px, 12px at phone width | 16px, the browser default |
| Characters per line | 77 | 45–90 |
| Line height | 1.00 | 1.5 (WCAG 1.4.8) |
| Text contrast | 12.6:1 | 4.5:1 (WCAG AA), 7:1 (AAA) |
| Text column | 68% of the window | at least 45% |
| Reflows at phone width | yes | WCAG 1.4.10 |
| Dark mode | no | noted, not scored |
| Automated accessibility checks | 3 automated checks failed (2 serious): button-name, html-has-lang, meta-viewport | WCAG 2.1 A and AA, via axe-core |
| Keyboard | no trap; focus visible on 100% of stops | never trapped, always visible |
| Structure | main landmark, 1 h1, no skipped heading levels | a main landmark, one h1, no skips |
| Alt text | 99% of 74 content images described | every content image |
| Reader mode | parses | parses (Firefox’s Readability) |
Automated accessibility checks catch an estimated 30–40% of real problems, so “no automated violations detected” is a floor, not a certificate. We never say “accessible”. How these are scored.
Recorded automated findings
| Recorded behavior | Policy cost | Use in this grade |
|---|---|---|
| Cookie dialog blocks the page, but you can refuse | 0.25 | Strongest verified cost only |
These records are retained for inspection. Only verified interruption evidence contributes to that subject; uncertain records are not silently treated as clean. Metering keeps its separate grade cap. These costs are not currently applied as search-ranking multipliers.
Measurement dates
Oldest evidence 50 days old. At least one subject is due for rechecking (30 days or older). Dates refer to the evidence, never the card rebuild.

Measurement history
Newest 3 saved observations. Each describes a sampled page at that time; older, failed or held observations do not override the current reviewed card. Raw automated findings may have been superseded by later review or detector replay. No previous grade is inferred.

How we know
| Pages rendered | 3 |
|---|---|
| Site verdict | errors dropped; majority of remaining; ties to the stricter verdict; active reviewed exclusions override admission |
| Figures shown | numeric measurements generally use medians; interruption costs, overflow, keyboard traps and accessibility failures retain the strongest observed finding |
| Cited by | 1,820 encyclopedia articles |
Think this is wrong? It may well be — the measurements cover only a handful of pages. Any reviewed admission decision and its dated evidence are shown above. Re-measurement on request is not built yet, so there is no button here that would do anything. When it exists it will be free and it will be on this page.
