How to Measure the Super Charger

  1. Select an image. Click the Select Image button to load a photo containing both the Super Charger and a known reference object.
  2. Enter the reference length. In the Known reference length field, type the real-world size (in your preferred units) of the object you’ll use for scaling. For example, if it’s 3 inches, enter 3.
  3. Mark the reference. Click on two points in the image that span the known reference object.
  4. Mark the Super Charger. Click on two points across the Super Charger.
  5. View the measurement. The tool will automatically calculate and display the Super Charger’s diameter in the same units you entered for the reference.

Tip: For the most accurate results, ensure both objects are on the same plane and minimize perspective distortion.
