Frequently Asked Questions

>How accurate are the storage estimates??
Estimates are based on official documentation for each database engine's storage layout. Actual sizes may vary due to compression, fragmentation, and engine-specific optimizations.
>Does it account for indexes??
Yes, you can specify index columns and types (B-tree, hash, GIN, GiST) and the calculator will include index storage overhead.
