Farmers all know it. When it comes to growing their businesses, the right building is everything.
That’s because workflow, storage capacity, and your ability to upgrade equipment down the line are all critical aspects of your farm’s continued success.
In this article, you’ll learn:
Let’s begin by learning how to size your new building.
When designing a post-frame building for your farm, it’s wise to start with door dimensions.
To determine door size, begin by measuring the widest piece of equipment you own. This means taking the true transport width, including attachments like planters, sprayers, disc harrows, toolbars, etc.
With this measurement in hand, a good rule of thumb is to then add 2 ft of clearance on both sides of the equipment, with an additional 1 ft clearance for overhead space.
So, to determine door openings:
To determine your full building width, add all of your equipment widths together, plus an additional 2–3 ft of clearance against each side wall and between each piece of equipment.

This number—combined with potentially added space for hay or grain operations—will give you your optimal width for ease of access, safe storage, and maneuverability.
Measuring your building in this way has a few distinct advantages:
Depending on the size of your operations, this is where some farmers get stuck—particularly those wanting very wide clear spans.
This is because most builders aren’t prepared to tackle the engineering and construction demands of very wide clear spans. However, if you’re needing a very wide building, you’re in luck.
Tristate specializes in high and wide—meaning 100’ clear spans for protecting even the most gargantuan farming operations.
If you’re intentional about growing your farm, it’s wise to plan long-term.
Over the last few decades, tractors, combines, and implements have only gotten larger—a trend reflecting the need for efficiency in maintaining larger fields.
Therefore, before finalizing your building dimensions, consider the following:
A larger building now is most often cheaper than building a second structure in the years to come.
