It depends on how much electricity you plan to use in your garage. If you only need one or two lights and three or four outlets that will be used to power a vacuum or a single power tool, you probably only need a 15 amp circuit breaker. If you plan to run more than one tool simultaneously or if you have a freezer or something else that draws a lot of power on a continuous basis, you would be better off putting your heavy draw appliances on a separate 15 amp circut or getting a 20-30 amp circuit breaker.

ProfessorThe size of the breaker box needed for a garage will depend on the electrical demand of the devices and equipment used in the garage. It is recommended to consult with a licensed electrician to determine the appropriate size and capacity of the breaker box based on the specific requirements of the garage.
Your question really depends on your local codes and what exactly you are wiring. With out know your local codes, all I can suggest is that you either do some research for your city, county, and state codes, which should be similar to the National Electric Code, or hire an electrician to plan it for you.
Electric garage heaters come in several sizes. A 1500 Watt 120 volt plug in heater would need a 15 amp circuit with 14 gauge wire for temporary use. A 5000 watt 240 volt heater would need a dedicated 25 amp circuit breaker and a 10 gauge wire. Every home is different and this is intended as a general reference only. Seek competent professional advice for your specific application.

How many 30amp slots in a breaker box are needed for 240v cook top?
You would need one 30 amp double-pole breaker in the breaker box for a 240V cooktop.
Installing a 120volt appliance what breaker is needed at the electric box?
For a 120-volt appliance, a single-pole breaker with a rating suitable for the appliance's power requirements should be installed in the electric box. The amperage rating of the breaker should match the current draw of the appliance to ensure proper protection and operation. It is important to consult with a qualified electrician to determine the appropriate breaker size for your specific appliance.
How do you read breaker box amps?
To determine the amps of a breaker box, look at the main breaker or label inside the panel. The number on the main breaker indicates the maximum amperage that the breaker box can handle. Make sure not to exceed this amperage to prevent electrical hazards.
How do you find out how big your main breaker box is?
You can determine the size of your main breaker box by looking at the number of circuits it can handle. A typical residential main breaker box is usually 100 amps, 150 amps, or 200 amps. You can also check the label on your breaker box or consult with an electrician for assistance.
How do you tell the difference between 100 amp and a 200 amp box?
You can typically determine the amperage of an electrical panel by looking at the main breaker. A 100 amp panel will have a main breaker rated at 100 amps, while a 200 amp panel will have a main breaker rated at 200 amps. Additionally, the size and number of circuit breaker slots can also be indicators of the amperage rating.
