What size main panel do I need?

I have a new construction home with a 200 amp 120 volt inside panel. I'm not sure what size outside main panel I need. I have several 220 volt items that will feed off of the main panel. 30 amps Dryer, 30 amps Water Heater, 30 amp double oven, 40 amp cook top, 30 amp and 70 amp for heating and cooling. I would like to be able to have about 6 or 8 extra slots in my outside panel for extra stuff outside that I may add later.

What exactly are you doing? Are you building this house? Adding on?

Why is your dryer, cooktop, double oven, etc outside? Why not use the inside panel? The thing you have listed account for 12 breaker slots. They make panels up to 42 slots.

I've never heard of a 200-amp 120-volt panel. In fact, 120-volt panels are extremely rare.

And I have no idea why you need both an inside panel and an outside panel. Why not just one or the other?

This is a new construction 3500 square foot home and there is a 200 amp 42 slot panel on the inside which 38 slots are used for all of the 120 volt items. Therefore I was figuring on putting all the 220 volts stuff on the outside in the panel outside. This way incase of an emergency you can turn all the electricity off from the outside. I would like a few extra slots for future stuff like maybe a Hot Tub, outside lights, garden pond for my wife etc, etc.

You can get a meter pan with shutoff. Good idea anyway.
