# Get The Size Of A Database

If you have connect access to a PostgreSQL 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.
