This is a voltage drop question. To answer this question a voltage must be stated.
A 500 MCM copper conductor will limit the voltage drop to 3% or less when supplying 350 amps for 150 feet on a 208 volt system.
A 3/0 aluminum conductor will limit the voltage drop to 3% or less when supplying 150 amps for 150 feet on a 240 volt system. This size will allow the conductor to be loaded to 120 amps. 150 x 80% = 120 Conductors are only allowed to be loaded to 80% or their rated capacity. If you need the full 150 amps then you would need to use a wire with a rating of 190 amps. 190 x 80% = 152 amps A 4/0 aluminum conductor will limit the voltage drop to 3% or less when supplying 190 amps for 150 feet on a 240 volt system.
A #6 copper ground conductor would be needed.
At the service entrance you will need AWG 1/0 gauge.
Yes, the wire size has to be increased. The existing 100 amp service will now probably have a #3 conductor with an insulation factor of 75 or 90 degrees C which is rated for 100 and 105 amps respectively. Increasing to a 150 amp service will use a #1/0 wire size. If you are thinking of an upgrade, skip the 150 amp service and go to a 200 amp panel. New homes are installing 200 amp 42 circuit panels. The extra cost is only reflected in the materials as the labour costs will be the same regardless whether a 150 amp or a 200 amp panel is installed. The wire size for a 200 amp panel is #3/0. With an insulation factor of 75 or 90 degrees C the rating is 200 or 210 amps respectively.
This is a voltage drop question. To receive an answer to this question the voltage of the service must be stated.

12 AWG.
It is not advisable to run a 20 amp circuit 150 feet without understanding the specific electrical load requirements and potential voltage drop over distance. It's important to consult with a licensed electrician to ensure the safe and efficient operation of the circuit over that distance.
43,560 square feet = 1 acre150 x 150 = 22,500 square feet = 0.517 of an acre (rounded)
A #10 copper conductor will limit the voltage drop to 3% or less when supplying 21 amps for 150 feet on a 240 volt system.
A 3/0 aluminum conductor will limit the voltage drop to 3% or less when supplying 150 amps for 150 feet on a 240 volt system. This size will allow the conductor to be loaded to 120 amps. 150 x 80% = 120 Conductors are only allowed to be loaded to 80% or their rated capacity. If you need the full 150 amps then you would need to use a wire with a rating of 190 amps. 190 x 80% = 152 amps A 4/0 aluminum conductor will limit the voltage drop to 3% or less when supplying 190 amps for 150 feet on a 240 volt system.
Wire is sized by the amperage that it is allowed to legally carry. To answer this question the amperage that you need at the garage must be stated.
A #6 copper ground conductor would be needed.
A #4 copper or #3 aluminium conductor will limit the voltage drop to 3% or less when supplying 30 amps for 150 feet on a 120 volt system.
Assuming the service voltage is 240 volts. A 2/0 aluminum conductor, with an insulation factor of 90 degrees C, will limit the voltage drop to 2% or less when supplying 125 amps for 100 feet on a 240 volt system.
its 50 yards, if you want a referance its about as long as half a football field
