Plumbing for new home

I am currently doing a home addition which includes installing 2 new bathrooms (toilet, sink, bath). Can someone give me guidance on what size waste and vent lines to run for these two new bathrooms. I know the main stack must have a 4 inch vent line but can I tie anything else into it?

Waste for the toilet either 3 or 4 depending on your local code regulations. Tub/shower 2", sink 1 1/2". Vent, 4" main, 1 1/2" loops for shower and sink. Check with the local building office to make sure you are doing this right. It wouldn't be right to take information from us, not knowing where you live, and get cross wise with your inspector. He will rule.
