This calculator determines your soil texture based on the percentage of sand, silt, and clay. Using the Mason Jar Test as demonstrated in the video below,you can also determine the measurements in in, cm, or mm after sedimentation. You can do this yourself with the Mason Jar Test. It doesn’t require a specific jar size or measurement unit. Just input the settled layer heights or a desired ratio, and the tool will calculate the percentages and classify your soil using the USDA texture triangle.
