You can only have monsters on your field whose total size doesn't go over 3.

So, you can have three size 1, one size 2 and one size 1, or just one size 3 (not taking size 0 into account); you can have less, this is just an example on the limit.

If you have ie. a size 3 on the field, if you want to call a new one, you must send monsters from your field to drop zone until the total number is 3.

so ie. if you have three size 1, and call a size 2, you must remove two of the monsters.
