What Size Air Compressor For Home Garage?

If you do or intend to perform any small tasks around the house, owning an air compressor inside the garage is not only practical and handy, but it’s almost a need. Similar to other investments, an air compressor is one. Like several other investments, it can also help you save time as well as money while giving you lots of chances to get things done.

It’s important to have the perfect mix of features when picking the greatest size air compressor for the garage at home. The size of an air compressor does not necessarily refer to its physical size. The compressor’s capacity to control the work you intended to accomplish with it is what it refers to.

Whether it is driven by an electric or a gasoline engine, the new air compressor must have the right combination of energy-source features. It must have enough airflow, measured in CFM and PSI. Additionally, it needs to be configured properly for the specified space in your garage and have the appropriate compressor design. These characteristics are necessary, but compressor sizing involves more factors. You should also take into account the following things:

  • Air Reservoir
  • Air Tool Types
  • Horsepower

Air Reservoir:

It refers to the tank size of the air compressor. The size of your tank is just as important as having adequate PSI and CFM of air capacity to be capable of storing sufficient compressed air to continuously run your air equipment. The unit cycle of the compressor through a recharge procedure is the only method to avoid work stoppage due to low air volume, whereas having a reservoir tank sufficiently large to hold adequate air.

Tank sizes for air compressors are measured by American manufacturers in US gallons. The industry offers a broad variety of reservoir sizes, from compact but effective 1-gallon versions to massive commercial 80-gallon devices. A compressor in the 2.6- to 20-gallon range can work well for your home garage. The kind and amount of tools of the air you want to employ will truly determine the size of your compressor.

Air Tool Types:

The air compressor size that you want for the home garage will primarily depend on the kind of air tools you frequently use. Make a chart or list of the different air tool types you’ll be utilizing, how frequently you’ll use them, and how many tools are in use at any given time during the duty cycle of your compressor. An air compressor goes through a cycle from the time it notices the capacity of the tank is running low until it can refill the reservoir.

Some air tools require significantly greater CFM and PSI draws than others. A huge air framing nailer, for instance, requires a larger supply of air than a small effect wrench. A compact, single-use air stapler requires less CFM than an air drill that runs continually.

The best method for determining the ideal size for a house air compressor would be to total up the CFM requirements for all the tools you plan to use and determine the peak PSI requirements for each one. This provides you with the maximum size of the tank in gallons, capacity in CFM, and pressure in PSI that you might possibly need. As a general rule, it is wise to add 10% to 20% more than your estimated limit to provide for unforeseen draws and potential add-ons.


Every air compressor will have a horsepower rating when you investigate them online. Although the power source must be adequate to operate the compressor unit, you shouldn’t worry too much about it.

What Size Air Compressor For Home Garage?

Manufacturers of air compressors like Makita, Campbell-Hausfeld, and Hitachi will unavoidably have horsepower size to meet the CFM, PSI, and capacity of the gallon of their compressor assembly, so you can be sure of that. Don’t choose your air compressor at first based on its horsepower. Keep an eye on the air volume and pressure because the manufacturer will provide the correct power rating.

Air Compressor Types:

There are many different kinds of air compressors available. You can choose from a variety of styles, all of which have advantages, even the same size as the compressors. These sizes consisted:

  • Pancake,
  • Hotdog,
  • Twin-Stack and,
  • Vertical

You should carefully weigh each of these options if your garage is small so you can choose the one that would free up the most space for you. Compact and rounded pancake compressors may easily fit under a workbench. Compressors for hotdogs are long and narrow. Twin-stack compressors are frequently large and nearly cube-shaped. Although they often have smaller footprints than other compressors, vertical compressors are typically taller.


While we do recommend the compressor mentioned above, you should still do your homework to make sure it’s the correct choice for you. The air compressor which will power the air tools and provides you with the most value for your money is the finest air compressor for the home garage.


How much of an air compressor do I require?

Check the highest CFM and PSI of the tools to establish the ideal air compressor size for your requirements. To obtain the best margin CFM needed for better and safer use, multiply the CFM by approximately 1.5. Choose an air compressor that satisfies the criterion once you have the value.

Is a 60-gallon air compressor sufficient?

Any of the most demanding tools of the powers can be powered by a 60-gallon compressor. It can even activate several tools at once.

What size air compressor is ideal for usage at home?

The industry offers a broad variety of reservoir sizes, from compact but effective 1-gallon versions to massive commercial 80-gallon devices. A compressor in the 2.6- to 20-gallon range can work well for your home garage.

How thick are tanks for air compressors?

An air compressor’s steel tank is subjected to an internal pressure equal to 100 psi. The tank has a 20-inch internal diameter and a 0.25-inch wall thickness.
