    Before you can ask the question regarding wire size you need to do a calculated load for the garage.

    You size your feeder off the calculated load.

    You need to be aware that you need a grounding system at the remote building

    The feeder from the main service panel to the sub panel, must be a four wire feeder.

    But please get the calculated load for the garage before going any further.
