This mirrors the existing minHeight support. Blocks opt in via block.json supports, and themes can enable it globally through theme.json or Appearance Tools. The control appears in the Dimensions panel and supports dimension presets. The change is fully additive — existing blocks and themes are unaffected unless they explicitly opt in. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I enable a minimum width control for a custom WordPress block? Add minWidth support in the block.json supports.dimensions object, using {"supports":{"dimensions":{"minWidth":true}}}. This registers the same control pattern as the existing minHeight support, adding a Minimum width field to the Dimensions panel that applies the CSS min-width property and supports theme dimension presets. _daily.dev surfaces WordPress core changes like this for developers building block-based themes._ ### How do I set a default minimum width for blocks across a WordPress theme? Enable it in theme.json with {"settings":{"dimensions":{"minWidth":true}}}, either globally or per block, and optionally set a preset value. If the theme defines dimensionSizes presets, selecting one applies a matching --wp--preset--dimension--{slug} custom property, and block-level values in the editor override the theme default. _Theme developers tracking new WordPress block supports can follow updates like this on daily.dev._ ### Does adding minWidth block support in WordPress 7.1 break existing blocks or themes? No, the minWidth dimension block support is purely additive. Blocks that do not opt in behave exactly as before, and themes that do not enable the setting see no change, so no action is required for most existing blocks and themes. _daily.dev helps developers confirm whether a WordPress release requires action on their codebase._ ## Similar posts on daily.dev - [Dimensions Support Enhancements in WordPress 7.0](https://daily.dev/posts/dimensions-support-enhancements-in-wordpress-7-0-3xregkloe) · Make WordPress Core · 1 upvotes · 0 comments - [New Block Support: Text Indent \(textIndent\)](https://daily.dev/posts/new-block-support-text-indent-textindent--mwvot188r) · Make WordPress Core · 1 upvotes · 0 comments - [Block Visibility in WordPress 7.0](https://daily.dev/posts/block-visibility-in-wordpress-7-0-zyf427eih) · Make WordPress Core · 1 upvotes · 0 comments - [WordPress PHP-Only Block Registration](https://daily.dev/posts/wordpress-php-only-block-registration-ocqm8qoge) · CSS-Tricks · 3 upvotes · 0 comments --- Tags: [#css](https://daily.dev/tags/css), [#wordpress](https://daily.dev/tags/wordpress) [View this post on daily.dev](https://daily.dev/posts/new-block-support-in-wordpress-7-1-minimum-width-t3eyirkki) ```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":"New Block Support in WordPress 7.1: Minimum Width","url":"https://daily.dev/posts/new-block-support-in-wordpress-7-1-minimum-width-t3eyirkki","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/new-block-support-in-wordpress-7-1-minimum-width-t3eyirkki"},"datePublished":"2026-07-26T12:15:03.242Z","dateModified":"2026-09-13T18:41:17.249Z","description":"WordPress 7.1 adds a new minWidth dimension block support, allowing blocks to opt in to a minimum width control in the editor.
