How can I find a Google BigQuery dataset size, not table sizes?

Question

I can see metadata details of tables in BigQuery, but for project estimations I'm hoping to see metadata of the entire dataset.

SELECT * From 'dataset'._TABLES_SUMMARY_WHERE size_bytes>0 isn't working for me.

Answer 1

SELECT SUM(size_bytes) AS bytes 
FROM [yourdataset.__TABLES__]
