Helium help : Comprehensive list of report parameters
Ratio (L/W), Girdle Ratio and Corner Ratio

Ratio (L/W) and Girdle Ratio

Applicable to All

Ratio (L/W) and Girdle Ratio are different parameters, but generally have equal values.

Ratio (L/W) = Length / Width
Girdle Ratio = (Diameter perpendicular to Minimum Diameter) / Minimum Diameter

Read detailed description about Width, Length and Diameters for different cuts.

Corner Ratio

Applicable to:

  • Step Cut
  • Princess
  • Cushion
  • Radiant
  • Square radiant

Corner Ratio = Diameter: Corner (Max) / Diameter: Corner (Min)
