The key parameter in sizing wire is the current requirement. Once you know that you can look up value in a wire gauge table. The length of the run is important for longer runs because of the resistance of the wire itself. Aluminum wire requires a larger diameter than copper for the same current. Once you calculate the wire size you can then size the conduit.
250 MCM aluminum minimum
depends on size....
No, the conduit has to be supported individually from a supportive structure. The spacing of the strapping is related to the size of the conduit.
For new 200 amp services the conduit size should be 3 inch PVC.
A trade size hole for a 2-1/2" EMT conduit connector, the hole needs to be 2-7/8" in diameter. A 3" rigid conduit can also use this size hole without the lock nuts falling into the hole.

ma - male adapter, fa - female adapter, coup - coupling, conn - connector, cap - end cap, reducer - bushings that reduce the size of a conduit to allow connection to a smaller size conduit, expansion joints - to allow the expansion and contraction in the conduit system.
The question can't be answered without knowing what the voltage is. That is because the allowed voltage drop is 5% of the supply voltage, so you need to know the supply voltage. Then the wire calculation aims to find out what the minimum size of wire is that produces that voltage drop or less.
A #1 aluminum wire with a insulation factor of 90 degrees C is rated at 105 amps. Three #1 wires can be installed into an 1 1/2" conduit.
4 inch rigid conduit

Actual hole size for 1 inch conduit is 1.362"
The size of conduit is based on the size of the wires in it. The size of the wires depends on the load connected in the house. Without these other two values an answer can not be given.

For new 200 amp services the conduit size should be 3 inch PVC.
