Purpose of the site

Calcula tu Proyecto offers free calculators to estimate quantities of construction and gardening materials. The tools run in your browser and are intended for informational and personal planning use.

Nature of the estimates and limitation of liability

The results the site provides are guideline estimates calculated from the data you enter and from common reference values. The actual amount of material can vary due to many factors: product brand and technical sheet, coverage, density, compaction, cuts, installation technique, waste, and the specific conditions of each project.

We do not guarantee that the estimates are accurate or fit for a particular purpose. We are not liable for excessive or insufficient purchases, cost overruns, damages, or any consequence arising from the use of the calculators. For structural elements or major works, always consult a qualified professional (engineer, architect, or technician) and verify the manufacturer's or supplier's specifications.
