Common Metal Building Sizes & How to Choose the Right One

Posted on July 3rd, 2024. 

One of the foundational aspects to consider when selecting a metal building is understanding its size measurements. 

These dimensions provide pivotal insights into how well the structure will fit within your available space and meet your storage or operational needs. 

For example, you might come across common sizes like 12x20, 20x30, or even 40x60 feet.

But what do these numbers actually mean for you? 

Incorrectly estimating any of these dimensions could result in a building that’s either too cramped or excessively large, each carrying its own set of challenges—sufficient space or budget overruns, you name it. Therefore, accurate measurements are essential to avoid such pitfalls. On top of that, other factors like the intended use, local zoning laws, and even regional climate conditions come into play. 

This post will cover the important dimensions to consider when planning for a building purchase. By fully considering these aspects, you can better understand the implications of your choices and ensure a smooth planning and budgeting process. 

Understanding Metal Building Measurements 

Typically, metal buildings are measured in terms of width, length, and height, and these measurements form the core specifications you'll need to consider when selecting a structure. These three dimensions dictate the overall footprint and internal space of the building:  

• Width: The width of a metal building refers to the distance from one side wall to the other. It is an important measurement as it determines the overall size and footprint of the structure. 
• Length: The length of a metal building is the distance from the front to the back. This measurement is crucial for determining the internal space and layout of the building. 
• Height: The height of a metal building is measured from the base to the top of the structure. It plays a significant role in determining the overall size and functionality of the building. 

Understanding these measurements is essential in determining if the building will fit in your available space and meet your storage or operational needs. Incorrect calculations in any of these dimensions can lead to issues such as insufficient space or over-budgeting. To ensure the best fit for your needs, it is crucial to measure your available space accurately and understand the exact sizing requirements before making a decision. This will help avoid any potential issues or setbacks in the future.

Common Metal Building Sizes 

When focusing on popular metal building sizes for residential use, several dimensions stand out because they effectively cater to various homeowner needs. Carports, garages, and small storage sheds are common examples where size plays a pivotal role.

Single-Car Carport 

A typical single-car carport generally measures around 12x20 feet, providing enough space to park one vehicle comfortably while ensuring you have some room for maneuver.

Double-Car Carport 

For a double-car carport, consider dimensions such as 20x20 or 20x30 feet, which allow you to park two cars side by side, and sometimes even provide extra room for light storage. Similarly, residential garages commonly range from 20x20 to 24x30 feet, offering space not only for parking but also for storage or a small workshop area.  

Sheds and Small Structures 

Common metal building sizes don't merely apply to carports and garages; they also extend to sheds and other small structures. A 10x12 shed is frequently used for basic yard equipment storage, garden tools, and seasonal items. If you need more room for larger tools or even a small workspace, a 12x16 or 12x20 shed can be the ideal choice. By examining your specific needs and the space you have available, these sizes offer flexibility and convenience without overcommitting resources.  

Multi-Functional Spaces 

Addressing multi-functional spaces, a 30x40 or 24x36 building can effectively serve dual purposes. For instance, part of the space could house a vehicle while another section functions as a workshop or extra storage area. The versatility offered by these dimensions means you can tailor your building to meet evolving needs, whether it’s adding shelving units, workbenches, or even HVAC systems for climate control.  

Commercial and Industrial Metal Buildings 

Common sizes for commercial an industrial metal structures vary widely based on their intended use. For small businesses or workshops, a 30x40-foot building provides ample space for operations, storage, and office areas. Larger enterprises might opt for a 60x100-foot building, which can accommodate extensive machinery, inventory, and even multiple departments under one roof. For industrial applications, sizes like 80x200 feet or larger are often necessary to house heavy equipment, manufacturing lines, and large-scale storage. These dimensions allow for flexible interior layouts, facilitating streamlined workflows and maximizing productivity.   

So, how do you know what size to choose for you metal building? Read on to learn some practical tips!

How to Choose the Right Metal Building Size

The size of your building will impact its functionality, budget, and overall efficiency. Whether you’re planning for commercial, industrial, or personal use, careful consideration of several factors will help you make an informed decision. Here are some key tips to guide you in selecting the perfect metal building size:

1. Assess Your Needs

Start by identifying the primary purpose of your metal building. Consider what activities will take place inside, the equipment or vehicles it will house, and any future expansion plans. Make a detailed list of your requirements, including the necessary square footage for each activity. For instance, a workshop may need different dimensions than a storage facility. Accurately assessing your needs helps avoid choosing a building that’s too small or excessively large, ensuring optimal space utilization and cost-efficiency.

2. Consider Future Growth

While your current needs are crucial, planning for the future is equally important. Estimate your business growth or potential changes in usage over the next 5 to 10 years. Opt for a size that can accommodate expansion without requiring major modifications. This foresight prevents the hassle and expense of outgrowing your building too quickly. Factor in additional space for potential new equipment, increased inventory, or additional employees. Building with future growth in mind ensures long-term utility and cost savings.

3. Evaluate Site Constraints

Examine the available space on your property where the building will be erected. Measure the dimensions of the area and take note of any limitations, such as nearby structures, zoning laws, and environmental considerations. Ensure that your chosen building size fits comfortably within the designated area without infringing on setbacks or easements. Site constraints can significantly impact the feasible dimensions of your building, so thorough evaluation is necessary to avoid potential issues during construction.

4. Budget Considerations

Your budget plays a critical role in determining the size of your metal building. Larger buildings typically come with higher costs, not only for materials and construction but also for ongoing maintenance and utilities. Define your budget early in the planning process and balance it with your size requirements. Consider potential cost-saving measures, such as phased construction or prioritizing essential spaces first. A well-planned budget ensures you achieve the desired size without compromising on quality or financial stability.

5. Consult with Professionals

Finally, seek advice from industry professionals, such as architects, contractors, and metal building suppliers. Their expertise can provide valuable insights into optimal building sizes based on your specific needs and constraints. Professionals can also assist in creating efficient layouts and suggesting modifications to better utilize space. Consulting with experts ensures you make informed decisions and helps you navigate any technical or regulatory challenges. Their guidance is invaluable in choosing the right size for your metal building project.
