Enter the eave height of the bin and the bin diameter into the Auger Length Calculator. This calculator estimates the straight-line auger length using a right-triangle approximation where the vertical leg is the eave height and the horizontal leg is half the bin diameter (the bin radius).

Auger Length Formula
The following two example problems outline the steps and information needed to calculate the Auger Length.
AL = \sqrt{E^2 + (D/2)^2}- Where AL is the Auger Length
- E is the eave height of the bin
- D is the bin diameter
To calculate auger length, use the Pythagorean theorem: square the eave height, add the square of half the bin diameter, then take the square root of the sum.
How to Calculate Auger Length?
The following example problems outline how to calculate Auger Length.
Example Problem #1:
- First, determine the eave height of the bin.
- The eave height of the bin is given as: 5 ft.
- Next, determine the bin diameter.
- The bin diameter is provided as: 6 ft.
- Finally, calculate the Auger Length using the equation above:
AL = √(E² + (D/2)²)
The values provided above are inserted into the equation below and computed.
AL = √(5² + (6/2)²) = √(25 + 9) = √34 ≈ 5.83 ft
Example Problem #2:
For this problem, the variables required are provided below:
eave height of the bin = 7 ft
bin diameter = 8 ft
Test your knowledge using the equation and check your answer with the calculator.
AL = √(E² + (D/2)²) = ?
