If you have hundreds or thousands of pages in your Notion workspace, the sidebar can become sluggish. It may stutter when scrolling, take seconds to expand a toggle, or freeze when you drag a page to reorganize it. This happens because Notion loads the entire sidebar tree into memory, and a large tree with many nested pages consumes significant resources. This article explains why the sidebar slows down and provides a structured cleanup plan to restore smooth performance.
Key Takeaways: Clean Up Your Notion Sidebar for Faster Loading
- Sidebar > Toggle collapse: Collapse all top-level toggles to reduce the number of visible items in the tree.
- Move unused pages to a private archive database: Remove them from the sidebar without losing data.
- Create a top-level hub page: Group related sub-pages under a single sidebar entry instead of listing each page separately.
Why a Large Sidebar Slows Down Notion
Notion renders the entire sidebar tree as a single DOM element. When you have more than 200 top-level pages or deeply nested sub-pages, the browser or desktop app must render thousands of nodes. Each node includes an icon, a title, a toggle arrow, and a drag handle. This causes layout recalculations on every scroll, expand, or collapse action. The problem worsens if you have many databases in the sidebar, because each database entry may also show its linked views. The root cause is that Notion does not virtualize the sidebar tree — it renders all items at once, unlike a typical file explorer that only renders visible items.
Steps to Clean Up and Speed Up the Sidebar
- Collapse all top-level toggles
Click the collapse arrow next to each top-level page that has sub-pages. This reduces the number of visible items in the tree. Notion only renders the expanded children when you open the toggle, so collapsing unused sections frees memory immediately. - Move old or unused pages to a private archive database
Create a new database called “Archive” in your private workspace. For each page you no longer need in the sidebar, open it, press Ctrl+A to select all content, copy it, paste it into a new page inside the Archive database. Then delete the original page from the sidebar. This preserves the content while removing the sidebar entry. - Create a top-level hub page for related sub-pages
Instead of having 50 meeting notes as separate sidebar entries, create one top-level page called “Meetings” with a linked database view or a simple table of contents. Move all meeting notes into that page. Now only one sidebar entry exists instead of 50. - Remove unused database views from the sidebar
Open each database in full-page mode. Click the view name dropdown and select “Delete view” for any view you do not use. Each view appears as a separate sidebar entry under the database. Removing unused views reduces the sidebar count. - Use the sidebar search instead of browsing
Press Ctrl+P to open Quick Find. Type the page name. This bypasses the sidebar entirely and loads only the page you need. Train yourself to use search for daily navigation instead of scrolling the sidebar. - Move private pages to a separate workspace
If you have personal pages mixed with work pages, create a second workspace for personal content. Switch workspaces using the workspace switcher at the top left. Each workspace maintains its own sidebar, so each one stays smaller.
If the Sidebar Is Still Slow After Cleanup
Notion desktop app uses too much memory
Open Task Manager on Windows or Activity Monitor on Mac. If Notion uses more than 1 GB of RAM, close and reopen the app. This clears the sidebar cache. Restarting the app once a week prevents memory leaks from accumulating.
Third-party integrations add sidebar items
Go to Settings & Members > Connections. Review each connected app. Disconnect any integration that adds pages or databases to your sidebar automatically, such as a Slack bot that creates a new page for every message. Remove the integration, then delete the pages it created.
Browser extensions interfere with sidebar rendering
Extensions like Grammarly, LastPass, or ad blockers can inject code into the Notion page and slow down the sidebar. Test by opening Notion in an incognito window with all extensions disabled. If the sidebar is fast there, disable extensions one by one to find the culprit.
Sidebar Cleanup Methods Compared
| Method | Effect on Sidebar | Effort Required |
|---|---|---|
| Collapse toggles | Reduces visible nodes immediately | Low — click each toggle |
| Move pages to archive database | Removes pages permanently from sidebar | Medium — copy and delete each page |
| Create hub pages | Replaces many entries with one | Medium — set up linked database or TOC |
| Remove unused database views | Shrinks database entries in sidebar | Low — delete unused views |
| Use Quick Find (Ctrl+P) | Bypasses sidebar entirely | Low — change habit |
| Move pages to separate workspace | Splits sidebar into two smaller trees | High — create new workspace and move pages |
By collapsing toggles and moving unused pages to an archive database, you can reduce the sidebar size by 50 percent or more. Using hub pages and removing unused database views further shrinks the tree. If the sidebar remains slow, restart the app or disconnect third-party integrations. The key habit to adopt is using Ctrl+P for navigation instead of manual sidebar scrolling. This single change will make the sidebar feel fast regardless of how many pages you keep.
