I have setup an index on a column name "no" and its of int data type.
There are total 59,309,499 records in the table but index size shouldn't be 59,309,499 * 4 (bytes) ?

Its currently 1488768204Bytes or you can say 1419.8MB while it should be 237237996Bytes or 226MB?

Please also let me know how index is exactly calculated if its set on other data types like varchar and when length is given like varchar(6)?
