Block Themes vs Classic WordPress: What to Choose in 2026

Since 2022, WordPress has moved toward Full Site Editing (FSE) — a new paradigm where the entire theme is built with blocks. By 2026, the technology is mature enough to be a serious choice. But should you abandon classic theme builders? It depends.

What Full Site Editing (FSE) is

FSE lets you edit the entire theme (header, footer, sidebar, templates for all content types) through a block-based interface. It replaces the traditional PHP-based theming approach.

Sites built with block themes use the native block editor (Gutenberg) for everything — no separate page builder required.

Block themes — strengths

• Unified editing — same system for content and template.
• Faster sites — no page builder overhead.
• Fewer plugins — reduces the risk of conflicts.
• Native WordPress features — patterns, theme.json, global styles.
• Better support — part of WordPress core, not a third-party plugin.

Block themes — weaknesses

• Still less flexible than Bricks or Elementor Pro for complex layouts.
• Smaller ecosystem of ready-made templates and patterns.
• Steeper learning curve for non-technical users coming from Elementor.
• Not all third-party plugins are FSE-compatible yet.

Classic theming with Elementor/Bricks — strengths

• Huge ecosystem of templates, plugins, and addons.
• More visual approach — drag-and-drop for every element.
• Greater flexibility for complex custom layouts.
• Lower learning curve for designers without technical background.

Classic theming — weaknesses

• Performance overhead — page builders add 30-50KB of JS and CSS per page.
• Recurring license costs — Elementor Pro is €60/year, Bricks is €99 one-time.
• Version dependency — builder updates sometimes break the site.
• Lock-in when migrating to another platform.

When block themes are the right call

Block themes are the right choice when:

• Building a new site from scratch.
• You need maximum speed and SEO performance.
• You don't want dependency on third-party plugins.
• You have a technical team that can build custom blocks when needed.

When classic is the better choice

• You have an existing Elementor site with invested design work.
• Your marketing team manages content and needs a visual builder.
• You need specific addons that exist only for Elementor/Bricks.
• You're building a site with many non-standard visual layouts.

Migration: from classic to block themes

Migration from Elementor to a block theme isn't automatic. Realistic steps:

1. Audit existing pages — which are important, which can be simplified.
2. Choose a new block theme or build a custom one.
3. Rebuild page by page in the block editor.
4. Migrate forms, popups, and custom functionality to FSE-compatible alternatives.
5. QA and SEO redirect setup.

For a site with 20-50 pages, migration takes 2-4 weeks. Pricing: €3,000-€10,000 depending on complexity.

Conclusion

For new sites in 2026 — block themes are now the technically right choice for most projects. Faster, cleaner, more sustainable long-term. The classic approach with Elementor or Bricks remains valid only for specific use cases or when there's an existing site already built around it.
