How can you determine how much disk space a particular MySQL table is taking up?

Question

Is there a quick way to determine how much disk space a particular MySQL table is taking up? The table may be MyISAM or Innodb.

Answer 1

Quick bit of SQL to get the top 20 biggest tables in MB.

SELECT table_schema, table_name,
  ROUND((data_length+index_length)/POWER(1024,2),2) AS tablesize_mb
FROM information_schema.tables
ORDER BY tablesize_mb DESC LIMIT 20;

Hope that's useful to somebody!
