How to see how much data is in Azure Blob Storage
- Sign in to the Azure portal
- Select Monitor from the left-hand pane, and under Insights select Storage Accounts
- Select all subscriptions and storage accounts in the drop-down lists
- Select Capacity at the top of the page and note Account used capacity and Blob capacity for each account
Record the sum of Blob capacity (or used capacity) across all storage accounts; the view shows up to 200 accounts at a time.

These instructions are written by DataFrenzy from each vendor’s public help pages. Menu names can vary by plan and change over time; the official link on each guide is the final word. Screenshots come from each vendor’s own help pages and videos or, where noted, from third-party tutorials credited under the image; dashed outlines are illustrations, not screenshots. Looking up a size or preparing an export never sends anything to DataFrenzy.
