Classical Orders Calculator, Mode: New Construction – perfect ratios

Four traditions, one modulus. Proportion columns from a single module — or from the place itself.

Classical Orders is a free, honest calculator for proportioning columns and elements across four great building traditions. No fudge factors, no hidden constants — just the documented proportions, honestly flagged where they’re contested.

What it does

Three ways to work

  • New construction — perfect ratios from your chosen modulus.
  • Fit to a fixed length — for existing conditions and real-world constraints.
  • The Solstice Quadrilateral — the frame computed from latitude alone, from the sun’s fixed solstice declination (±23.44°).
Classical Orders Calculator, Mode: Fixed to a length

Four traditions

  • Greek / Roman — Vignola proportions (Tuscan, Doric, Ionic, Corinthian, Composite).
  • Egyptian — papyriform and lotiform columns.
  • Indian / Tamil — the Mayamata canon.
  • Chinese — the Yingzao Fashi cai module and dougong.

Two unit systems — centimeters and feet/inches, with the column diameter entered in both at once.

The Mandala of Place — compute the solstice quadrilateral frame from latitude alone: the MC and MS measures, the element lengths, and the Sons and Daughters squares.

Why it’s honest

  • Proportions are best-studied references, flagged where values are contested.
  • The solstice quadrilateral is computed from latitude and the sun’s fixed declination — nothing invented.
  • The Mandala of Place draws on Secrets of Sacred Geometry (Crowley-Susani, Parker & Susani), with a link to the book rather than a reproduction of the authors’ interpretation.
