The landscape of WordPress design is changing quickly — and Block Themes and Full Site Editing (FSE) are leading the way. No longer do only developers have the ability to customize layouts and tweak templates. The entire process of being a site has gotten visual, flexible and unbelievably simple as the Gutenberg editor by WordPress took over.
At SaskatoonTech, these technologies are a game-changer in the way businesses create and manage their online identity. Read on about why block themes and FSE are significant game-changers for WordPress in 2025.

What Are Block Themes and Full Site Editing?
Before we get into the “why,” let’s kick things off with the “what.”
Block Themes are the all-new way of making WordPress themes—simple and powerful, but with very little code. Instead of featuring PHP templates, block themes utilize blocks for every portion of your website — from the header and footer to the content area and sidebars.
On the flip side, Full Site Editing (FSE) pertains to anything that enables a user to visually edit and customize any piece of their site from within the WordPress UI. Through FSE, you can change how your site looks, its global styles and colours, as well as the typography – all without having to write any custom code.
1. Design Freedom Like Never Before
The Classics WordPress themes often restricted customization too, unless you were ready to try your hand at theme files or use a sophisticated page builder tool.
With block themes and FSE, everything is editable — the header, the footer, post templates and now even a 404 page. Drag and drop blocks, rearrange some elements, and preview the changes in real time.
This level of flexibility enables both developers and non-technical users to create professional-quality custom designs fast, saving time and effort in the development process.
2. Faster Development and Easier Maintenance
It means developers don’t have to create custom templates for every page design. With the site editor and template parts, you can use design blocks again across your designs, getting that consistency and speed up in building sites.
For companies like SaskatoonTech, that means quicker project delivery, easier maintenance and less reliance on cumbersome page builders. And it means cleaner code, and page performance that is better for the end users.
3. Enhanced Performance and SEO
Block themes are included as part of WordPress core, so they’re leaner, faster and more efficient than older themes, which rely on being built on top of multiple frameworks or plugins.
Fewer dependencies allow for faster load times, better Core Web Vitals and in turn SEO rank — all essential for online success in 2025.
4. Consistency with Global Styles
The headline feature in FSE is Global Styles that allow you to define site-wide design elements — like colours, fonts and spacing — in one place.
Not only does this ensure brand continuity, but it also means that any future changes to your lettering would be easy to update. Looking to refresh your brand colour scheme? Change it once, and your entire site is updated in a flash.
5. A More Unified Editing Experience
Before FSE, you needed to toggle between Customizer and Widgets all the time if you wanted to make minor design adjustments.
And now, everything is edited in one cohesive space – the Site Editor. It’s cleaner, it’s more intuitive, and best of all, it minimizes confusion when clients are managing their own sites.
6. Future-Proofing WordPress Websites
WordPress is unequivocally heading toward being a block-friendly environment with the Gutenberg project leading it.
Embracing block themes today means your site will keep up with the latest updates, get locked in on new features and stay compatible with future versions of WordPress.
In other words, adopting block themes today means your website will be more modern, secure, and flexible for years to come.
7. Better Collaboration for Teams
Thanks to the visual editing interface, designers, developers, and writers can now all work together in harmony.
Designers can design and set up blocks and templates; developers can write custom dynamic functionality, while the content team has easily-editable fields, without concerns about breaking layouts.
Wrapping Up
Block Themes and Full Site Editing aren’t just new features; they’re a completely different way to think about developing on top of WordPress. They make creating a site faster, cleaner and more accessible to everyone.
For companies, that translates to lower development costs, faster launches and the ability to keep a gorgeous, high-performing website without facing technical roadblocks.
At SaskatoonTech, we’re supporting brands with this next evolution of WordPress design — producing sites that are not only fully flexible but also future-proof and built to perform.
