How to get the font_name and font size of a page on scanned PDF documents?

I have used blocks > lines > spans > size for extracting text based pdf, but looking similar for scanned pdf document. Can someone please help me here?

There is no way in the world to achieve this. It has nothing to do with whatever tool you use: this information simply is not there.

It all depends on how clever the scanner / OCR-tool are which created the PDF. I know that e.g. ABBYY does a decent job with guessing the an approximate font.

Whatever:
Once the PDF is created, its content is all you have.
