If you are using Homebrew to install MySQL 5 7  the location is   usr local Homebrew var mysql   I don t know if the location is the same for other versions

As suggested  I edited this message to place a proper answer   The  physical  location of the mysql databases are under  usr local mysql  the mysql is a symlink to the current active mysql installation  in my case the exact folder is mysql-5 6 10-osx10 7-x86 64   Inside that folder you ll see another data folder  inside it are RESTRICTED folders with your databases   You can t actually see the size of your databases  that was my issue  from the Finder because the folder are protected  you can though see from the terminal with sudo du -sh  usr local mysql data  your-database-name  and like this you ll get a nice formatted output with the size   In those folder you have different files with all the folders present in your database  so it s safer to check the db s folder to get a size   That s it  Enjoy

If you install MySQL via homebrew on MacOS  you might need to delete your old data directory  usr local var mysql  Otherwise  it will fail during the initialization process with the following error      gt   usr local Cellar mysql 8 0 16 bin mysqld --initialize-insecure --user hohoho --basedir  usr local Cellar mysql 8 0 16 --datadir  usr local var mysql --tmpdir  tmp 2019-07-17T16 30 51 828887Z 0  System   MY-013169   Server   usr local Cellar mysql 8 0 16 bin mysqld  mysqld 8 0 16  initializing of server in progress as process 93487 2019-07-17T16 30 51 830375Z 0  ERROR   MY-010457   Server  --initialize specified but the data directory has files in it  Aborting  2019-07-17T16 30 51 830381Z 0  ERROR   MY-013236   Server  Newly created data directory  usr local var mysql  is unusable  You can safely remove it  2019-07-17T16 30 51 830410Z 0  ERROR   MY-010119   Server  Aborting 2019-07-17T16 30 51 830540Z 0  System   MY-010910   Server   usr local Cellar mysql 8 0 16 bin mysqld  Shutdown complete  mysqld 8 0 16   Homebrew

See if you have a file located under  etc my cnf   If so  it should tell you where the data directory is    For example    mysqld  set-variable local-infile 0 datadir  var lib mysql socket  var lib mysql mysql sock user mysql       My guess is that your mysql might be installed to  usr local mysql-XXX   You may find these MySQL reference manual links useful    Installing MySQL 8 0 on MacOS Installing MySQL 5 7 on MacOS Installing MySQL 5 6 on MacOS Installing MySQL 5 5 on MacOS
