What It Does

Flexible Spacer Block adds a dedicated Gutenberg block that inserts adjustable vertical whitespace between other blocks on a page. Each spacer can be set with separate height values for desktop, tablet, and mobile, letting you fine-tune rhythm and breathing room without writing custom CSS. It is a single-purpose layout tool focused entirely on responsive spacing control.

Who It's For

This plugin fits site owners who build landing pages, portfolios, or editorial layouts directly in the block editor and want pixel-level control over vertical rhythm per device without reaching for a full page builder. It is especially handy for freelancers, small agencies, and content teams who already use Gutenberg and just need a reliable spacer block that beats the default WordPress Spacer. If you care about responsive spacing and dislike tweaking margins in CSS, this is aimed at you.

Who Should Skip It

If you already use a block suite like Kadence Blocks, Spectra, or GenerateBlocks, the spacer functionality is likely built in and adding another plugin is redundant. Anyone running a classic theme-based site with no Gutenberg usage will get no value from it.

The Bottom Line

Flexible Spacer Block is a small, well-maintained utility that does exactly one thing well: responsive vertical spacing in the block editor. The perfect rating, recent updates, and forward-compatible requirements are strong positives, but a support track record of zero threads and a 4,000 install base mean you are betting on a niche developer rather than a large community. If you already run Kadence or Spectra, skip it; if you want a focused spacer without bloat, it earns a look.

Pick Spectra if you want a broad block library that includes spacers alongside dozens of design blocks, buttons, and containers in one package.

Kadence Blocks — Page Builder Toolkit for Gutenberg Editor 89/100

Choose Kadence Blocks if responsive spacing is just one item on a larger wishlist of layout, typography, and template controls with strong preset support.

Starter Templates – AI-Powered Templates for Elementor & Gutenberg 89/100

Opt for Starter Templates if your priority is importing full pre-built site designs rather than manually tuning spacers between blocks.

Classic Widgets 89/100

Classic Widgets is unrelated to layout but appears in the category set; reach for it only if you need to restore the legacy widget screen, not spacing control.

PublishPress Blocks – Block Controls, Block Visibility, Block Permissions 88/100

Pick PublishPress Blocks when you need granular visibility and permission controls on top of standard Gutenberg blocks, not just spacing tweaks.
