The property addresses font legibility inconsistencies when fallback fonts are used: different fonts render at visually different sizes even with the same font-size value due to varying x-heights. font-size-adjust lets authors specify an 'aspect value' (x-height divided by font-size) from their primary font, so fallback fonts are scaled to maintain consistent legibility. Firefox has supported this property for years; this implementation brings it to Blink, with WebKit planned as a next step. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What does the CSS font-size-adjust property do and how does it work? font-size-adjust lets you maintain consistent visual legibility when fallback fonts are used in a font-family stack. Different fonts render at different apparent sizes even at the same font-size value because they have different x-heights. font-size-adjust accepts an 'aspect value' (x-height divided by font-size) from your primary font, and the browser scales fallback fonts so their x-height matches, keeping text readable regardless of which font is actually rendered. _Web developers managing multi-font stacks track CSS property support like this on daily.dev._ ### Does Blink or Chrome support font-size-adjust? font-size-adjust landed in Blink's nightly build and can be tested by enabling experimental web platform features at chrome://flags. Firefox had supported the property for a long time before this implementation. WebKit support was planned as a follow-up step after the Blink work was completed. _Keeping up with browser feature rollouts matters when you're deciding which CSS properties are safe to ship — developers doing that follow daily.dev._ ## Similar posts on daily.dev - [Honoring Mobile OS Text Size](https://daily.dev/posts/honoring-mobile-os-text-size-f7qgzgxuw) · Adrian Roselli · 0 upvotes · 0 comments - [Try text scaling support in Chrome Canary](https://daily.dev/posts/try-text-scaling-support-in-chrome-canary-zh7hnyphu) · Hacker News · 0 upvotes · 0 comments - [New to the web platform in June](https://daily.dev/posts/new-to-the-web-platform-in-june-ego8ywxmf) · web.dev · 0 upvotes · 0 comments - [Text scaling support in Chrome Canary – Frontend Masters Blog](https://daily.dev/posts/text-scaling-support-in-chrome-canary-frontend-masters-blog-w8neiwwgr) · Frontend Masters · 1 upvotes · 0 comments --- Tags: [#css](https://daily.dev/tags/css) [View this post on daily.dev](https://daily.dev/posts/blink-started-supporting-font-size-adjust-css-property-eglrqhnzm) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Blink started supporting font-size-adjust css property","url":"https://daily.dev/posts/blink-started-supporting-font-size-adjust-css-property-eglrqhnzm","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/blink-started-supporting-font-size-adjust-css-property-eglrqhnzm"},"datePublished":"2026-08-11T08:54:05.426Z","dateModified":"2026-08-11T09:31:10.431Z","description":"The CSS font-size-adjust property has landed in Blink's nightly build, available via experimental web platform features in chrome://flags.
