Unlike basic calculators that only assume round diameters, this tool uses the drill-to-drill distance. This means you can accurately plan layouts for irregular baroque, drop, and rice pearls, not just round ones.
The math accounts for physical realities. You input your target length, the drill-to-drill pearl size, the thickness of your silk knots, and your specific clasp length. The tool gives you the exact pearl count required.
