What A Website Sidebar Is And How It Works On Squarespace
A website sidebar is a familiar feature on many websites, yet it’s rarely planned with intention. It’s the narrow column that appears alongside the main content of a page—most commonly on blogs and resource-heavy layouts—and it’s designed to support, not distract from, what someone is reading.
Sidebars exist to provide context, direction, and next steps. When used well, they help readers navigate related content, find helpful resources, and stay engaged with a site beyond a single page.
On Squarespace sites, sidebars can feel confusing because the platform does not include a native sidebar feature. As a result, many site owners aren’t sure whether sidebars are possible, practical, or worth the effort. That uncertainty often leads to sidebars being ignored entirely, even when they would be useful.
This post walks through the fundamentals so you can make an informed decision. Specifically, you’ll learn:
What a website sidebar is and what it’s designed to do
Where sidebars are most commonly used and why blogs are a natural fit
Why sidebars feel less straightforward on Squarespace sites
How Squarespace users can easily add a functional sidebar to their site
This post is meant to help you decide, intentionally, whether a sidebar belongs on your website and how it might support your content.
What a Website Sidebar Is
A website sidebar is a secondary content area that sits alongside the main content of a page. Its role is supportive. It exists to complement what someone is already reading, not to compete with it.
Unlike headers or footers, which usually appear across an entire site, sidebars are most often used on specific page types. Blogs, articles, and long-form resources are the most common examples. On these pages, the sidebar provides additional context or options without interrupting the main flow of content.
When using a sidebar, it should have a clear purpose tied to the page it appears on. That purpose is usually tied to highlighting related content, offering a relevant resource, or pointing readers toward a logical next step.
If the concept still feels abstract, it can help to think about how sidebars work in print. Magazines often place short callouts, pull quotes, tips, or related blurbs alongside the main article. Those elements aren’t the story itself, but they add context, emphasis, or an entry point for readers who want more. A website sidebar serves a similar role in a digital format.
FAQ
Q1: Should every page have a sidebar?
A1: No. Sidebars are typically used on content-heavy pages like blogs or long-form resources. Pages that are focused on a single action—such as a homepage or a sales page—often work better without one.
Q2: Does every website need a sidebar?
A2: No. Some websites function well without sidebars. They tend to be most useful on content-heavy sites where visitors spend time reading and may benefit from additional guidance or resources.
Where Website Sidebars Are Most Commonly Used
Website sidebars are most commonly used on blogs. Blog posts tend to attract readers who spend more time on the page—scrolling, reading, and engaging with the content. A sidebar fits naturally into that experience because it provides additional context or options without pulling attention away from the main article.
On a blog, the primary content does the heavy lifting. The sidebar plays a supporting role by giving readers a place to go next once they’re already engaged. This might include related posts, a relevant resource, or a brief reminder of what the site offers.
Sidebars can also work well on other long-form or content-heavy pages, such as resource libraries, guides, or evergreen articles that continue to receive traffic over time. These pages benefit from having a consistent secondary area that helps orient readers and encourages deeper engagement with the site.
What these pages have in common is reader intent. Someone visiting a blog post or resource page is there to read and learn. A sidebar works best in that context because it supports that experience rather than interrupting it.
Other places where a sidebar often makes sense include:
Resource libraries or collections of downloads
Evergreen articles that continue to receive search traffic over time
Guides or long-form educational pages
Blog category or archive pages
Reference-style content that benefits from related links or added context
FAQ
Q1: Why are sidebars so common on blogs?
A1: Blog readers typically spend more time on the page than visitors to other parts of a site. That longer engagement makes it easier to present related content or resources in a sidebar without disrupting the reading experience.
Q2: Are sidebars useful outside of blogs?
A2: Yes. Sidebars can also be effective on resource pages, guides, and other long-form content where readers may benefit from added context or a clear next step.
Why Sidebars Feel Harder on Squarespace
For many site owners, the confusion around sidebars starts with the platform itself. Squarespace does not include a native sidebar feature. There isn’t a built-in setting or layout option that allows you to add a sidebar alongside blog posts or content pages by default.
Because of this, people often assume one of three things: that sidebars aren’t supported, that they’re outdated, or that adding one requires rebuilding the site. None of those conclusions are especially helpful, but they’re understandable given how Squarespace presents its layouts.
Most Squarespace templates are designed around full-width sections stacked vertically. That structure works well for many pages, but it leaves little room for secondary content areas that live alongside the main content. As a result, sidebars tend to disappear from consideration entirely, even when they would support the content well.
This limitation doesn’t mean sidebars are a bad idea on Squarespace. It means they require a different approach. When a platform doesn’t offer something natively, the question becomes whether that feature is unnecessary—or simply missing from the default toolkit.
FAQ
Q1: Why doesn’t Squarespace have a native sidebar feature?
A1: Squarespace templates are designed around full-width, stacked sections that prioritize visual simplicity and consistency across devices. This layout approach works well for many page types, but it doesn’t naturally support secondary content areas that sit alongside the main content, such as sidebars.
Q2: Does the lack of a native sidebar mean sidebars don’t belong on Squarespace?
A2: No. It means sidebars aren’t part of Squarespace’s default layout system. When a sidebar is useful—especially on blogs or long-form content—it simply requires a solution that works within Squarespace’s structure rather than against it.
Adding a Sidebar on Squarespace (and What to Look For in a Solution)
Squarespace makes it easy to build clean, full-width layouts, but it doesn’t offer a built-in way to add a sidebar alongside blog posts or long-form content. For site owners who publish regularly, this often creates a gap between how their content functions and how their layout supports it.
When a sidebar would be useful—on blogs, guides, or resource pages—people are left to improvise. Some abandon the idea altogether. Others attempt workarounds that are difficult to maintain or inconsistent across pages. Over time, the issue isn’t just layout. It’s friction.
A practical sidebar solution for Squarespace needs to do a few things well:
Work reliably across blog posts and content pages
Remain consistent without requiring constant rebuilding
Fit within Squarespace’s structure rather than fighting it
Allow content updates without redesigning the layout
This is where the Sidebar Plugin from SQSP Themes fits naturally. It’s designed specifically for Squarespace sites and makes it possible to add a functional sidebar where one would otherwise be unavailable. The plugin provides a structured way to include secondary content alongside your main content, without changing how the rest of your site is built.
For sites that rely on blogging or long-form content, a sidebar isn’t about adding more elements. It’s about supporting what’s already there.
FAQ
Q1: Why would someone use a plugin instead of adjusting the layout manually?
A1: Manual layout adjustments can be time-consuming and difficult to maintain, especially as content grows. A plugin provides a consistent structure that can be reused across pages without rebuilding the layout each time.
Q2: Is a sidebar plugin necessary for every Squarespace site?
A2: No. A sidebar makes the most sense for sites that publish content regularly or rely on long-form pages. If a site is primarily made up of short, action-focused pages, a sidebar may not add value.

Deciding Whether a Sidebar Belongs on Your Site
A website sidebar isn’t a requirement, but it can be a useful supporting element when your site relies on blog posts, guides, or other long-form content. The key is understanding when it adds clarity and when it doesn’t. For Squarespace users who want that added structure, having a reliable way to include a sidebar makes the difference between settling for a layout and intentionally supporting the content you’ve already worked hard to create.
