Supply line to irrigation system from Meter

What size should the water pipe be from the meter to the valve assembly? My supply into the house is 3/4″. I am going to use 1″ valves and pipes in my irrigation system but am wondering if I can use 1/2″ pipe between the meter and the valves. The reason I want to do this is to save on the cost of the pipe, but I won’t do it if it will seriously impede the water flow in my system. No manuals or design guides I have seen discuss this. Thanks!
