Hi Alexander,

You can use the :sysinfo command in Query as a quick estimate (the “Store Size” reflects the logical database size), which is generally sufficient for sizing managed Neo4j Aura on AWS.

However, for AWS EC2 self-hosting, you should measure the actual on-disk files because AWS bills based on provisioned storage.

In Neo4j Desktop 2 your instance path can be found by selecting '...' on the instance card then Open Instance folder, then navigate to the data folder. At the command line on MacOS/Linux run the following inside the data folder to see a breakdown of store size needed for each database and associated transaction logs.

du -h . --max-depth=1

For Windows right-click the data folder > properties > size on Windows.

Finally, provision additional headroom (e.g., 20–40%) for growth.
