Scored across 14 tools
Each tool targets a distinct object to size (rug, sofa, chandelier, curtain, mirror, umbrella, etc.), and the descriptions call out the specific inputs and rules so boundaries are clear. The only adjacent pair, chandelier_size vs. pendant_spacing, is cleanly separated by context (room/dining table vs. kitchen island).
Thirteen tools follow a predictable object_attribute pattern (sofa_size, rug_size, curtain_length, pendant_spacing, wall_art_size), which is readable and consistent. list_visualizers breaks the pattern as a verb_noun action tool, a minor but real deviation from the sizing-calculator convention.
Fourteen tools sit squarely in the well-scoped range, and each calculator earns its place by covering a different product category a person would size. Nothing appears redundant or padded.
The sizing domain is covered broadly across seating, lighting, tables, rugs, window treatments, mirrors and art, giving good end-to-end coverage for room planning. Minor gaps exist for common items like beds/mattresses, dressers, TV mounting height, and desks, and list_visualizers is the only non-calculator navigation tool (no search or page-fetch).
