Grain bin storage planning is an important part of harvest preparation. Whether you're managing a farm grain setup or a commercial grain elevator, knowing how many bushels fit in a bin helps prevent overfilling and improves inventory management.
A grain bin capacity calculator makes it easy to estimate how much grain your storage bins can hold.
Grain Bin Capacity Basics
Grain bins are usually measured using:
-
diameter
-
sidewall height
-
grain type
-
moisture content
Capacity is typically calculated in bushels.
Different grains store differently due to test weight.
Examples:
-
Corn ≈ 56 lb per bushel
-
Soybeans ≈ 60 lb per bushel
-
Wheat ≈ 60 lb per bushel
Example Grain Bin Capacities
| Bin Diameter | Approx Bushels |
|---|---|
| 18 ft | ~4,000 |
| 24 ft | ~8,000 |
| 30 ft | ~13,000 |
| 36 ft | ~20,000 |
| 42 ft | ~28,000 |
These vary depending on sidewall height.
Managing Grain Inventory
Once grain is stored, many farms and elevators track:
-
grain by bin
-
incoming truck loads
-
outgoing shipments
-
transfers between bins
Without a system, inventory can become difficult to track.
If you're managing multiple bins or commodities, AG Shed Pro provides a complete inventory tracking system for agricultural operations.
AG Shed Pro allows you to:
• track grain by bin
• monitor inventory levels
• manage incoming and outgoing loads
• track seed and chemical inventory
