Grain Bin Capacity Calculator

Summary

Enter your bin diameter, eave height, and optional peak height to calculate grain bin capacity in bushels and metric tons for common grain types.

How it works

1. Enter the bin diameter (inside measurement, in feet).
2. Enter the eave height — the vertical sidewall from floor to where the roof begins.
3. Optionally enter the peak height — how far the roof cone rises above the eave.
4. Select a grain type from the preset list, or enter a custom bulk density.
5. Click Calculate to see total capacity in bushels, cubic feet, and metric tons.
6. Adjust inputs and recalculate to compare different bin sizes or grain types.

Use cases

• Estimate whether an existing bin can hold a full field harvest before delivery.
• Compare cylindrical bin sizes when planning a new grain storage facility.
• Calculate total on-farm storage across multiple bins of different dimensions.
• Estimate stored grain weight for structural load, insurance, or logistics planning.
• Determine how many bushels of a specific crop fit in a bin using its real density.
• Verify reported bin capacities against measured diameter and height.
