How Big Is A Three Car Garage?
The standard size of a three car garage is 20 feet wide by 30 feet deep, with a height of 10 feet. This provides enough space for three cars to be parked comfortably, with room to spare for storage or a workshop. However, the actual size of a three car garage can vary depending on the specific needs of the homeowner. For example, a homeowner who needs to store a large vehicle or boat may need a wider or deeper garage. Additionally, the height of the garage may need to be increased if the homeowner plans to use a lift to store a car.
When determining the size of a three car garage, it is important to consider the following factors:
- The size of the cars that will be parked in the garage
- The amount of storage space that is needed
- The need for a workshop or other workspace
- The height of the garage
Once the homeowner has considered these factors, they can begin to determine the ideal size for their three car garage. It is important to note that the size of the garage will also impact the cost of construction. A larger garage will require more materials and labor, which will increase the overall cost.
In addition to the standard size, there are also a number of other factors that can affect the size of a three car garage. These factors include:
- The type of garage door that is used
- The number of windows and doors in the garage
- The presence of any built-in features, such as a workbench or storage cabinets
By considering all of these factors, the homeowner can determine the ideal size for their three car garage. By following these tips, the homeowner can ensure that their garage is the perfect size for their needs, while also staying within their budget.
Here are some additional tips for determining the size of a three car garage:
- Measure the size of your cars. This will give you a good starting point for determining the overall size of the garage. Be sure to add a few feet of extra space for maneuvering and storage.
- Consider your storage needs. If you need to store a lot of items in your garage, you will need to add extra space for this purpose. You may also want to consider installing shelves or cabinets to help you organize your storage space.
- Think about your future needs. If you are planning to add a car to your family in the future, you may want to build a garage that is large enough to accommodate this. You may also want to consider adding extra space for a workshop or other workspace.
- Get professional advice. If you are not sure how to determine the size of a three car garage, you can consult with a professional home builder or architect. They can help you design a garage that meets your specific needs and fits within your budget.
By following these tips, you can ensure that you build a three car garage that is the perfect size for your needs.
