Selecting the right size is the first step towards a perfect two-car garage. It seems easy because you think you only have to measure two things: “Vehicles” and “Property Size”. But it’s not enough for a perfect metal garage size for two cars. You need to consider many other factors that lead to the perfect garage size.

You also need a space where you can store tools, equipment, and seasonal items easily and keep them safe from different weather conditions.

We have made this decision easy for you with our well-researched steps. Moreover, some size ideas to help you analyze what fits best for your needs.

So, without further ado, let’s get started.

Minimum Size for a Two Car Steel Garage

This garage should be at least 20 feet wide and 20 feet long. However, this size is only suitable for two small cars, such as compact sedans. But if you also try to store a bicycle inside the garage, it will feel tight. If you want comfortable movement, you will have to go with some extra space.

Examples:

  • 22×25 Steel Garage – This size garage can fit two mid-size cars like sedans or small SUVs, with a bit of extra space at the sides and back. You can also add storage racks where you can store tools related to car maintenance. Generally, the price of two car steel garage of this size can vary; having an idea of the starting price can help you make further decisions. This garage price starts at $2195.
  • 24×30 Steel Garage – This size is ideal for two larger vehicles, like SUVs or a truck and a car. It offers room for wall-mounted shelves, a small workbench, or seasonal storage boxes. So, you can have practical long-term storage options and do not have to buy a new garage just to store a car and some tools. This garage price starts at $2995

Two Car Metal Garage Size: Easy Steps to Find Out

Choosing the correct size becomes easy when you know the right steps. Here they are. Just scroll to the perfect space that not only fits your vehicles but tools and other stuff.

1. Know Your Cars, Know Your Space

The very first step begins with measuring the cars or vehicles that you want to store inside a garage impeccably. If you have a standard-sized car, a 20×24 size will be enough. But if you have two SUVs and pickups, this size will not be suitable for your needs. Likewise, always add a clearance space. If you want, you can store tools and use metal buildings for retail and warehousing by going with more space.

2. Don’t Forget Storage Needs

When you install a garage, you not only create a space for your cars, but also create space for things related to its maintenance. Since buying a two-car garage is a significant decision, you will also want to utilize the space to store other items to maximize its value. To do this, try to make a list of things you want to store inside the garage, apart from vehicles. Everyday items people store include bicycles, garden tools, sports gear, and seasonal decorations.

Ask yourself, “How much extra square footage is need to be added if storage is a priority?” The answer depends on what you want to store. Here is a quick example: 2 cars with side storage racks or 2 cars plus a rear storage wall. The storage space also depends on how you want to store your vehicles. Here are two ways to store them.

3. Height Matters Too

Most of the time, steel garage buyers only focus on height and length; they tend to avoid height. But what if they need to store taller vehicles in the future? Standard garages are about 7 – 8 feet tall, which works for small cars. However, if you own SUVs, trucks, or cars with roof racks, you will need more clearance to avoid damage. Extra height also allows you to install overhead storage racks or even a loft for seasonal items.

So, considering height is as crucial as other dimensions. Moreover, the type of roof style matters to protect both your cars from snow, rain, and storms. Vertical garages can be particularly beneficial for those living in areas with heavy snowfall.

4. Customize for Your Lifestyle

How frequently do you use cars? Do you use one car more than the other? Do you wash your car at home or at a car wash shop? How many tools do you want to store? Do you need a lean-to? The list of questions goes on when it comes to customization. But it’s better you make a long list of questions because it will clear your doubts and prepare you to explain your requirements clearly in front of a metal building dealer.

Add-on options:

  • Side doors
  • Windows
  • Shelves
  • Lofts
  • lean-to

But if you want to use a car garage for other purposes, customization can’t go the same way. Because now you have to make the space functional to meet different needs. If you use it as a workshop and garage combo, the size needs to grow.

5. Think of Budget and Long-Term Use

Budget and durability may not seem related to garage size at first, but upon deeper analysis, they are. Because larger dimensions result in a higher price, and long-term value equates to cost-effectiveness. Often, going slightly bigger saves money later because you have enough space to store more items without needing to install an additional building.

Discuss with your metal building dealer and ask about the cost per square foot of steel space. Also, ask about gauge steel frames because the thickness of steel affects the measurements. Do not forget to think about future needs. If you are going to have kids, they will also need some vehicles for children, hobby tools, and you may need cars, larger than the size you have currently.

Types of Two Car Metal Garages

After understanding the steps, you must now be confident to make a decision. But one more thing you should be aware of is the type of metal garages. Often, the type of two-car garage affects your budget and plan for purchasing the structure. Therefore, it’s better to be aware of them beforehand.

  • Metal Workshop
  • Boxed-eave Garages
  • Lean-to Garage
  • Clear Span Garages

Build Space That Grows With You

Follow the steps mentioned above and determine the right size for the garage. Measure the size of both your cars, think carefully about your storage needs, consider height, budget, and, finally, don’t forget to consider your lifestyle. The garage size should not only fit your cars, but also your modern lifestyle. Likewise, a two-car steel garage can grow with you if you focus on some points while determining the specifications. Keep your most likely near-future needs in mind, so you will not need to purchase a new building in just a short time.
