dragons - Towards the end of Game of Thrones season 7, has Drogon become larger than Balerion was?

Daenerys Targaryen's dragons gradually increase in size over the course of Game of Thrones (the TV series), and Drogon seems to be the largest.

At the end of season 7 (episodes 6 or 7, shouldn't matter really), how does Drogon's size compare to Balerion the black dread, Aegon I's dragon? Also, is its growth known to have/have not stopped?

Answer

Balerion seems to be bigger - just compare the skull of Balerion to the head of Drogon:

Cersei next to Balerion skull

Jon next to Drogon

But keep in mind that Balerion is much older than Drogon, as he lived for two centuries, so maybe Drogon will keep growing and become larger than Balerion.
