Check data modeling size for each table

Hi Anonymous 

There isn’t a built-in field in Power BI Desktop that shows the size of each individual table in the data model.

One basic workaround is to copy a specific table into a new PBIX file, save it, and check the file size — but this only gives a rough approximation.

It’s also important to understand that total model size is not simply the sum of the table sizes. It depends on several factors, including:

• Relationships between tables

• Column cardinality (number of unique values)

• Encoding method used (value vs. hash encoding)

• Visuals, filters, and how the data is consumed in the report

For a more accurate and detailed analysis, you can use external tools like:

🔹 DAX Studio – Connect your model and run VertiPaq Analyzer, which gives you a full breakdown of table and column sizes, cardinality, compression rate, and more.
🔹 Tabular Editor – Also useful when working with larger models and optimizing metadata.
