+# Get The Size Of A Database
+
+If you have connect access to a database, you can use the
+`pg_database_size()` function to get the size of a database in bytes.
+
+```sql
+> select pg_database_size('hr_hotels');
+ pg_database_size
+------------------
+          8249516
+```
+
+Just give it the name of the database and it will tell you how much disk
+space that database is taking up.
+
+Checkout [the Postgres docs](http://www.postgresql.org/docs/current/static/functions-admin.html) for more details.
