From free entry to curated instrument
The pyramid calculator was rebuilt around a single Select Pyramid menu: Khufu, Khafre, Menkaure, Djoser, Bent, Red, Meidum, and Unas, ordered by public recognition. Results converted to the site’s Giza royal cubit of 0.523748 metres: heights and bases in royal cubits, volumes in royal cubits cubed, slope annotations in seked palms, with the sourced metric dimensions kept visible.
Shapes that refuse the template
Two monuments got honest special-casing rather than forced fits: Djoser modelled as a rectangular stepped envelope, and the Bent Pyramid as two slope zones. Named-constant tests carry an explicit exploratory tolerance, and every result links to its evidence basis and a dedicated study; seven new study pages shipped with the redesign, and the Temples hub grew from ten cards to seventeen.
Promoted
Validation passed 242 pages and 5,994 internal links with zero errors and zero warnings, and version 4 was promoted to production the same evening.
