I would like to know how much space does my MySQL database use, in order to select a web host. I found the command SHOW TABLE STATUS LIKE 'table_name' so when I do the query, I get something like this:

Name       | Rows | Avg. Row Length | Data_Length | Index Length
----------   ----   ---------------   -----------   ------------
table_name   400          55            362000        66560

• numbers are rounded.

So do I have 362000 or 400*362000 = 144800000 bytes of data for this table? And what does Index Length mean? Thanks !
