Solution 1Recommended

View Folder Size via the Details Pane

The quickest and most direct way to check a folder's size in OneDrive online is by accessing its built-in Details pane.

OneDrive's web interface does not display folder sizes in the main list view by default. You must inspect each folder individually using the properties menu to calculate its storage footprint.

Select the target folder

Log into your OneDrive online account. Hover your cursor over the folder you want to check, and click the circular checkmark on the left side to select it.

Open the Details pane

Click the three-dot menu icon (Show actions) located next to the folder name or on the top navigation bar, then select 'Details' from the dropdown menu.

View More details

In the Details pane that opens on the right side of your screen, scroll down to the bottom and click 'More details'. This will expand the pane to reveal the exact folder size and total file count.

Sync Delay: If you recently uploaded large files to the selected folder, it may take a few moments for the 'More details' section to update and reflect the accurate folder size online.

Frequently Asked Questions

Can I view the size of multiple OneDrive folders at once online?

No, the standard OneDrive web interface only allows you to view the size of one folder at a time through the Details pane. For an overview of multiple folders, you need to check them individually or view your 'Storage Metrics' page if you are using a OneDrive for Business account.

Why does my OneDrive folder show zero bytes online?

If a folder appears empty or shows zero bytes in the More details pane, it may still be syncing data to the cloud, or it might only contain shortcut links instead of actual file data.

How do I check my total available storage space in OneDrive?

To check your total storage quota, click the gear icon (Settings) in the top right corner of the OneDrive web interface, select 'Options' or 'OneDrive settings', and then navigate to the 'Manage Storage' section to see your overall usage.
