Angle of Impact Calculator
Calculate the impact angle of an elliptical stain from its measured width and length.
Formula
Impact angle = arcsin(stain width / stain length).
About the Angle of Impact Calculator
Calculate the impact angle of an elliptical stain from its measured width and length. This tool keeps the requested measurements separate and applies the named method instead of substituting an unrelated general estimate.
How the Angle of Impact Calculator Works
The minor axis is divided by the major axis and the inverse sine is converted to degrees.
Formula
Impact angle = arcsin(stain width / stain length).
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.
Required Inputs
- Stain width (required) - enter in mm.
- Stain length (required) - enter in mm.
Results Reported
The result panel reports the final answer and the intermediate quantities needed to check the calculation:
- Width-to-length ratio
- Impact angle (deg)
- Angle from vertical (deg)

Accuracy and Limitations
Measure only the elliptical body and exclude tails or spines. Perspective, surface texture, and irregular stains can invalidate the simple model.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
