There is a community post that contains this information:
How much storage space do I get?
We provide ten gigabytes (10 GB) of storage space for your workbooks (aka. vizzes).
You can find the community post here:
Hope this helps
Thank you for the link. I guess wasn't searching at the right place.
By the way, is the 10GB per account? It's not per workbook, correct?
In the way I read and understand it, it is per account
Thank you, Matthias.
And with Tableau Public's 10 million row limit, most workbooks remain relatively small. The largest I've created was about 80 MB and that was just because I had merged 25 shapefiles together as a source.
