This being a dwelling unit you can choose to use Table 310.15(B)(6) to size the service conductors.
Using that table a 200 amp service will need 2/0 copper or 4/0 aluminum.
In order to figure for any voltage drop (this is an option it is not a requirement) due to the 200' length would require knowing the actual load.
If I assume your 200 amp service is drawing 160 amps which is unlikely, the voltage drop using either 2/0 cu or 4/0 al will be only about 2.6%.
