Answers: Using the alternative computation method in the national electrical code, you would involve a minimum service rated at 95 amps. With taking within to account the method utilizes 125% of the largest nouns ( your oven) you can get by near 100 amp at a minimum. If you plan to add any adjectives electrical items, hot tub etc, plan on 150 or a 200 amp panel and service would not be out of the question.
Today for you modern home a 200 amp is more the norm than not.
You can't install anything less than a 100 amp distribution panel so I would be in motion that route 100 amps will be fine. If you plan on adding things contained by the future step 150. any higher than that and I would obligation to know the distance you re from the service.. (pole) but for what you describe without knowing I would guess 3BR 2 hip bath, 100 will be fine..
