Surface Area Increase Calculator

Cones are approximated and peak heights follow a normal distribution ±1 mil around the mean. Base diameter is set as % of spacing using the slider (25–150%).

Flat Surface Area (cm²) Average Peak Height (mils) Density input type

Linear Peak Density (peaks/cm)

Increase spacing between peaks by 2× (reduces density)
