AES is a block-level algorithm. So when data encrypted it is padded. So you can calculate the length of the result string using this formula:

1
16 × (trunc(string_length / 16) + 1)
So if your address field structure is = VARCHAR(100) ; //100 length of varchar
Then before your encryption it should be converted
= 16 * (trunc(100/ 16) + 1)
= 16 * (6.25 + 1)
= 16 * 7.25
= 116
