WordPress Full Site Editing: A Complete Guide (2026)

WordPress full site editing changes how you build a site. Instead of juggling the Customizer, widget areas, and a theme’s PHP files, you design every part of your site with blocks. Headers, footers, single posts, and archive pages all become editable in one place.

This guide covers what full site editing is, how the Site Editor works, and where it fits next to classic themes and page builders. You’ll see how templates, global styles, and patterns connect into one system. By the end, you’ll know how to start and what to watch for.

WordPress 6.8, released in April 2026, made the experience production ready for real client work. The features below reflect that release.

What Is WordPress Full Site Editing?

Roughly 60% of new WordPress themes now ship as block themes, the format full site editing depends on. Full site editing (FSE) is the feature set that lets you edit your whole site with blocks, not just the content inside a post.

It arrived in WordPress 5.9 back in January 2022. Since then, default themes like Twenty Twenty-Four and Twenty Twenty-Five have shipped as block themes built for it. Every part of the layout, from the header down to the 404 page, becomes a block you can move, restyle, or replace.

The whole system runs through one screen called the Site Editor. That single canvas is what people mean when they say “fse wordpress” or “site editing.” You no longer hop between separate tools to change separate parts of the page.

Full Site Editing vs the Classic Customizer

You change a color in the Customizer, then dig through a widget area to fix the footer, then open a third screen for menus. Full site editing folds those jobs into one interface.

The Customizer shows a live preview, but it only exposes the options a classic theme chooses to offer. Want a setting the developer skipped? You write CSS or edit template files. Control stops where the theme’s options end.

The Site Editor flips that model. You click directly on a header, type new text, swap a button color, and the change applies site wide. Classic themes still rely on the Customizer, so the right tool depends on the theme you run. Block themes use full site editing, and classic themes keep the older path.

Inside the WordPress Site Editor

Open Appearance then Editor, and you can change your site header in under a minute. The WordPress site editor opens to a visual map of your site with a sidebar for the main areas.

That sidebar holds five sections: Navigation, Styles, Pages, Templates, and Patterns. Click any one to jump straight into editing. WordPress 6.8 added Data Views, a filterable list that lets you sort pages, templates, and patterns from a single screen instead of clicking through each.

The Style Book is the other standout. It previews every block in your theme on one page, including hover and focus states for buttons and links. For the official walkthrough, the WordPress.org Site Editor documentation covers each panel in detail.

Templates and Template Parts

Most beginners mix up templates and template parts on day one. The difference is simple once you see it.

A template defines the layout for a type of content. Your blog posts share a “Single” template, your category pages share an “Archive” template, and your homepage uses a “Front Page” template. Edit one template and every page of that type updates together.

A template part is a reusable chunk you drop into multiple templates. Your header and footer are the classic examples. Build the header once as a template part, place it across your templates, and one edit changes it everywhere. This is the core of full site editing wordpress workflows, and it saves hours of repeat work.

Global Styles and the theme.json Connection

Here is a detail many tutorials skip: the Global Styles panel is a visual front end for a code file. Open Styles in the Site Editor and you are editing the same values stored in your theme’s a single theme.json file.

That file holds your design tokens. Colors, typography scale, spacing units, and layout widths all live there. Change a brand color in Global Styles, and WordPress writes it back to the theme’s settings. Style variations let you ship several presets, so a visitor or admin can switch the whole look with one click.

This is also where your theme’s design system takes shape. A clean color palette and a consistent type scale make every later edit faster. For the full reference, see the theme.json developer handbook.

How Patterns Speed Up Full Site Editing

Building a pricing section block by block is slow. Patterns fix that. A pattern is a pre-built group of blocks you insert in one click, then edit in place.

WordPress ships a directory of block patterns for heroes, testimonials, FAQs, and more. The catch with generic libraries is fit. A pattern looks polished in the preview, then clashes with your fonts and colors once it lands on your page.

This is where Strakture fits. It reads your theme’s design system, the colors, fonts, and spacing already defined in theme.json, then generates new block patterns that match. The free tier lets you browse and insert originals. Paid plans add AI generation tuned to your active theme. Other pattern tools exist, but most ship one fixed design and hope it works everywhere, while Strakture builds each pattern around your specific tokens.

How to Get Started With Full Site Editing

One setup choice decides whether full site editing is even available to you. Follow these steps in order.

1. Activate a block theme. Twenty Twenty-Five is free and built for FSE. Check Appearance, and if you see “Editor” instead of “Customize,” you are set.
2. Open the Site Editor. Go to Appearance then Editor to load the visual canvas.
3. Set your global styles first. Lock in colors, fonts, and spacing before you build pages, so every section inherits them.
4. Edit your templates and parts. Adjust the header, footer, and single-post layout once for site-wide consistency.
5. Add patterns to fill pages. Insert a hero or pricing block, then tweak the copy.
6. Save and preview. Use the Save button, then view the front end on desktop and mobile.

Limitations and Gotchas

Full site editing is not the right call for every site, and pretending otherwise helps no one. A few honest trade-offs are worth knowing before you commit.

First, it only works with block themes. If a client runs a classic theme with heavy customization, switching means a rebuild. Second, the learning curve is real for anyone used to the Customizer, since the mental model is different. Third, some older plugins still assume the classic editor and can behave oddly inside templates.

There are also data limits. Pulling dynamic content into a template once meant custom code, though the Block Bindings API in recent releases now connects custom fields to blocks without it. Check that your host runs WordPress 6.5 or newer so the current Site Editor features are available.

FSE Site Editor vs Customizer vs Page Builders

Three tools can shape a WordPress layout, and each suits a different job. This table sums up where each one wins.

Factor	FSE Site Editor	Classic Customizer	Page Builders
Theme required	Block theme	Classic theme	Most themes
Editing scope	Whole site: header, footer, templates	Theme options plus widgets	Page and post layouts
Output	Native WordPress blocks	Theme dependent	Often extra markup or shortcodes
Performance	Light, no add-on	Light	Can add page weight
Design control	Global styles plus per block	Limited to theme options	High, fully visual
Cost	Free, built in	Free, built in	Often paid

Page builders still lead on free-form drag and drop. The Site Editor wins on speed, clean output, and native WordPress behavior that survives theme and plugin updates.

Design Your Whole Site in One Place

Full site editing turns a scattered set of screens into one canvas. You set global styles once, build templates that update in bulk, and drop in patterns to move fast. The result is a site that stays consistent and loads light. If you are tired of nudging patterns to match your theme by hand, Strakture reads your design tokens and generates patterns that fit on the first try.
