Pottery Sherd Curvature to Vessel Capacity Estimator

Estimate the original vessel's radius, diameter, and a speculative capacity based on a pottery sherd's curvature.

Important Disclaimers:
  • The radius/diameter calculation is an **approximation**, as pottery is rarely perfectly round.
  • **Capacity estimation is highly speculative** and depends heavily on your assumed vessel shape. A single sherd provides very limited information about the overall vessel form (e.g., its full height, whether it's a jar, bowl, or bottle).
  • This tool is for **illustrative purposes only** and not for precise archaeological or scientific analysis.
