Planning tools built around trust

Why it exists

Decorative layouts often combine repetitive spacing, mixed units, practical rounding, and material estimates. A bare calculator can produce a number while leaving the datum, assumptions, or installation meaning unclear. This project joins the calculation with measurement guidance, a visual check, and an explanation of the result.

How tools are selected

The project starts with one focused interior-layout problem and expands only to adjacent tasks that can provide distinct, maintained value. It does not create duplicate pages for countries, spelling, units, or entered values.

Editorial responsibility

Formulas, examples, measurement language, and limitations are reviewed as product behaviour. Advertising is disabled in this baseline and must never influence a calculated result. Material changes to formulas or rounding require updated specifications and regression tests.

What the tools are not

Results are planning aids, not structural engineering, building-code, certification, or manufacturer advice. Verify site conditions and seek qualified trade advice where the project requires it.
