One of the best things about metal barns, especially for kits, is that you can build one at any size you want. However, one of the most important questions is: “What is the common size for metal barns? “

Its intended use will determine how big or small your metal barn should be. There are specific sizes for each intended purpose.

Metal barns have become increasingly popular in recent years due to their durability, versatility, and cost-effectiveness. These barns provide a reliable and practical solution for a variety of needs. 

This article explores the different sizes of metal barns, the factors that influence their dimensions, and why the common sizes vary across different applications.

Factors Influencing the Size of Metal Barns

The size of a metal barn is not a one-size-fits-all decision. Several factors influence the dimensions of a metal barn, with some being directly related to the purpose of the barn and others depending on the land available and local regulations. Understanding these factors will help you determine the right size for your needs.

1. Intended Use 

One of the most significant factors affecting the size of your metal barn is the intended purpose. A barn used for storing hay or equipment will likely require different dimensions than one used to house livestock. For instance, a small equipment barn might only need a space of 20 feet by 30 feet, while a barn for horses or cattle may need to be much larger.

• Livestock Barns: If you plan to use your metal barn for housing livestock like cattle, horses, or goats, the size will depend on the number of animals you intend to house. The National Agricultural Statistics Service suggests a minimum of 100 square feet per animal for smaller livestock like goats and sheep. For horses, the recommended space is generally around 120 square feet per animal.
• Storage Barns: If the primary purpose of your metal barn is to store equipment, tools, or hay, the size will need to accommodate the type and quantity of items you plan to store. Larger barns may have specific sections for equipment storage, separate spaces for hay, and even workshops or offices.
• Workshop or Garage: Many homeowners or small business owners utilize metal barns as workshops or garages for various projects or to house machinery. These barns typically require an open floor plan and sufficient headroom for equipment, tools, and vehicles. Workshops or garages may vary from 24 feet by 36 feet to larger sizes depending on the scope of the projects.

1. Available Land 

The amount of space available on your property will also dictate the size of your metal barn. For properties with a lot of land, you may be able to build a larger barn that can accommodate various activities, including animal housing, storage, and workshops. However, for properties with limited space, you may need to opt for a smaller barn that maximizes the available area without overwhelming the landscape.
Local zoning laws and building codes also play a critical role in determining the maximum allowable size of your barn. Some regions have strict regulations regarding the height, size, and placement of structures on residential or agricultural properties, so it’s essential to check with local authorities before finalizing your plans.

1. Budget 

The size of your metal barn will be influenced by your budget as well. Larger barns will naturally cost more due to the increased amount of materials and labor required to build them. If you are working within a specific budget, you may need to prioritize certain features or reduce the overall size of your barn. Fortunately, metal barns are often more affordable than traditional wood barns, allowing for more flexibility in design without breaking the bank.

1. Future Expansion 

It is also worth considering future expansion when deciding on the size of your barn. If you anticipate growing your livestock, equipment collection, or workspace in the future, it may be beneficial to build a larger barn from the outset. Alternatively, you could choose to build a smaller barn with the option to add on later, giving you the flexibility to scale your structure as needed.

Common Sizes for Metal Barns

The size of a metal barn is highly flexible and can be customized to fit your unique needs. However, there are several common sizes that are often seen in the industry, depending on the barn’s intended use. Below are some of the most popular dimensions for different types of metal barns.

1. Small Metal Barns (12’x24’ to 24’x36’) 

Small metal barns are typically used for storage, small-scale farming, or as workshops for personal use. These barns can fit on smaller properties or properties with limited space and are usually built with a minimal number of animals or equipment in mind.

• 12’x24’: This size is ideal for storing a few pieces of equipment or providing a small amount of shelter for livestock. It’s often used as a basic storage barn or a small workshop for personal use.
• 24’x36’: A common choice for those who need a bit more space, this size is often used for small-scale equipment storage, workshops, or housing a couple of animals. It can also serve as a multipurpose space that houses both animals and equipment.

1. Medium-Sized Metal Barns (36’x48’ to 40’x60’) 

Medium-sized barns are a popular choice for homeowners and small business owners. They provide ample space for storage, livestock, or workshops while remaining compact enough to fit on most properties.

• 36’x48’: This size provides ample room for housing livestock, storing equipment, or setting up a workshop. It’s a great option for people who need to store large farm equipment, like tractors or hay balers, but also want space to house a few animals.
• 40’x60’: With a larger footprint, this size is ideal for those who need space for multiple purposes, such as livestock, storage, and a workshop. It offers enough room to comfortably house animals, store equipment, and even have an office or workspace within the barn.

1. Large Metal Barns (60’x80’ to 80’x100’) 

Large metal barns are typically used for commercial farming, larger livestock operations, or large-scale workshops. These barns offer maximum flexibility and ample space to accommodate a wide range of activities.

• 60’x80’: This size is common for larger operations, such as commercial farms, equestrian facilities, or businesses that need large equipment storage and workspace. It can easily house large numbers of animals while also providing storage for feed, hay, or machinery.
• 80’x100’: The largest size commonly seen, this barn offers an expansive space that can house large numbers of livestock, as well as provide storage and workshop areas. It is ideal for large-scale operations such as commercial farming, warehousing, or even as an industrial workshop for businesses with multiple vehicles and equipment.

1. Custom Sizes 

In addition to the common sizes mentioned above, many metal barns are built to suit specific needs, meaning custom sizes are also an option. Custom barns are often designed for unique property layouts, specific farming needs, or specialized equipment storage. These barns can be as large or small as needed, offering full flexibility for those who have particular requirements.

Choosing the Right Size for Your Metal Barn

When deciding on the size of your metal barn, it’s important to keep a few key considerations in mind. First, assess the space available on your property and check any local building regulations that may restrict the size of your barn. Next, consider your specific needs: Are you planning to house livestock, store equipment, or create a workshop? Finally, ensure that your barn is large enough to accommodate your needs both now and in the future.

A good rule of thumb is to plan for future expansion. Even if you don’t need a huge barn right away, building a slightly larger structure now can save you money in the long run by reducing the cost of adding on later. Keep in mind that your barn’s size may also need to accommodate other features like doors, windows, and insulation, all of which can affect the overall design.
