4 Small Grain Bin Sizes: A Comparison
It’s important to have your grain stored safely and effectively. On the bigger farms, massive grain bins keep thousands of bushels of grain stored away. But what about the smaller farmer? It’s too expensive to invest in a 30’ tall grain bin, plus it’s very inefficient. That’s where small grain bin sizes come into play. That’s what this article is all about–a detailed overview of the different small grain bin sizes.

This is one of the smallest grain bin sizes you can purchase. Often, this size comes on wheels and can be transported easily across your property.
3-Ton Small Grain Bin Size
Here’s an example of a 3-ton small grain bin that’s available in both stationary and portable variations.
Height: 8’ 2”
Dimensions: 6’x6.5’
Capacity: 145 ft.³ / ≈ 116 bu.
Weight Rating: 6,000 lbs.
Wheels/Legs: Stationery or Portable
Grain Door Height Off Ground: –
Pros: Portable; stable; durable
Cons: Small

With double the capacity of a 1 ½ ton small grain bin, the 3-ton grain bin can be sold as stationery or portable. For example, Farmco’s 3-ton grain bins are constructed from heavy-duty 12-gauge steel with high-quality welds and carefully placed reinforcements.
5-Ton Small Grain Bin Size
A step up from the 3-ton, Farmco also builds a 5-ton grain bin size.
Height: 11’6”
Dimensions: 6’x6’
Capacity: 260 ft.³ / ≈ 185 bu.
Weight Rating: 10,000 lbs.
Wheels/Legs: Stationery
Grain Door Height Off Ground: 23”
Pros: Larger small grain bin size; durable; rain-proof metal lid; adjustable hitch for easy transport
Cons: Relatively expensive
Link: https://www.farmco.ag/portable-grain-bins/5-ton-grain-bin/
With a 10,000 lbs. grain storage capacity, this small grain bin size can be built for stationary or portable use. As always, 5-ton grain bins are built to last and will save you a lot of time and money on grain transport from the mill.
30-Ton Small Grain Bin Size
Here’s an example 30-ton grain bin.
Height: 27’8”
Dimensions: 11’1”x11’
Capacity: 1,381 ft.³ / 1,109 bu.
Weight Rating: 30,000 lbs.
Wheels/Legs: Stationery
Grain Door Height Off Ground: –
Pros: Greater grain storage capabilities; save money in the long run
Cons: Expensive

Although branching a bit into the regular-sized grain bins, a 30-ton grain bin is still relatively small compared to the 1,000+ ton grain bins that are available on the market. Grain bins like this help small-to-medium-sized farms not to have to make constant trips to the feed store. To learn more, here’s a great review of a 30-ton grain bin.
Speaking of reviews, here’s a table review:

Now that you’ve got a basic overview of some small grain bin sizes, we’ll dive into some more niche questions surrounding the topic.
What are the Dimensions of a Small Grain Bin?
A small grain bin’s dimensions depend on the size of your farm and the amount of grain that you want to store. Some small grain bin dimensions would be 6’x6’ (the height would vary depending on storage capacity) or 6’x6.5’.
What Is the Life Expectancy of a Small Grain Bin?
Typically, the life expectancy of a small grain bin ranges from 25-50 years. It could even last you for over a 100 years, depending on the quality of the grain bin and the amount of maintenance and care given to your small grain bin setup.
Here are several factors that can affect a small grain bin’s life expectancy:
- Fill cycles (wet grain and drying)
- Too small of a grain bin
- Corrosion
Here are several ways to keep your bins well-maintained and lasting for as long as possible.
- Vacuum the grain bin and make sure there is no debris or dust left behind
- Paint your grain bin (corrosion prevention)
- Plan ahead so that your grain bin is big enough for future storage use
How Do I Measure A Small Grain Bin’s Size/Capacity?
We’ll break down how to measure a small grain bin’s capacity by cylindrical and square small grain bins.
Cylindrical Small Grain Bin
If you have a cylindrical small grain bin, you can use the formula V=πr²h to find the storage capacity of your small grain bin setup.
For example, let’s say you have a grain bin that has a 6 ft. diameter and is 10 ft. tall. First, divide 6 ft. by 2 to find the radius. Then square 3 to get 9 ft for r². Multiply 9 ft. by π by 10 ft. to find the cubic feet of the small grain bin (which is 282.6 ft.³ in this example).
To find the number of bushels, simply divide the number of cubic feet by 0.8 to find your answer. In our example, that number is 353.25 bushels.
Square Small Grain Bin
For square small grain bins, the formula is V=lwh. Simply multiply the length, width, and height together to find the cubic feet of your small grain bin setup. From there, divide the number of cubic feet by 0.8 to find the number of bushels.
Using the same numbers from the above example, (6 ft. length and 10 ft. height) we’ll also say that the width is 6 ft. So multiply 6x6x10 and you get 360 cubic feet. Divide that by 0.8 and you get a 450-bushel capacity.
Type of Small Grain Bin | To Find Cubic Feet | To Find Bushels |
Cylindrical Small Grain Bin | V=πr²h | Cubic ft. ÷ 0.8 |
Square Small Grain Bin | V=lwh | Cubic ft ÷ 0.8 |
What is the Price for a Small Grain Bin?

Small Grain Bin Size | Cost |
10-Ton Grain Bin | $$$$ |
