Review Version History and Storage Metrics
Identify hidden storage consumers like document version history, recycle bin, and cached content that aren't calculated the same way in the admin center.
The SharePoint admin center often calculates site storage based on live active data, whereas the detailed Storage Metrics page includes all stored bytes. This discrepancy frequently comes from multiple file versions, recycle bin items, and metadata.
Navigate to your SharePoint site, click the Gear icon in the top right, and select 'Site information' followed by 'View all site settings'.
Under the 'Site Collection Administration' section, click on 'Storage Metrics'.
Review the list to see which libraries are consuming the most space. Click into the largest libraries to see if previous file versions are taking up excess gigabytes.
Go to the Library Settings, click 'Versioning settings', and reduce the 'Keep the following number of major versions' limit to free up space automatically.

Frequently Asked Questions
Does emptying the SharePoint Recycle Bin reduce the Storage Metrics total immediately?
Emptying the site and site collection recycle bins will reduce the storage metrics immediately at the library level, but it may take some time for the Admin Center total to update.
How can I find out how much space file versions are taking?
In the Storage Metrics page, you can click on specific files within a library. A breakdown will display the size of the current version alongside the size consumed by all historical versions.
Why doesn't the Admin Center match the site's Storage Metrics?
The Admin Center aggregates storage using a different indexing schedule, and may exclude certain cached data, audit logs, or system files that the detailed Storage Metrics page accounts for at the exact moment of viewing.
