About DiyEstim

DiyEstim is a free collection of material estimators for homeowners and DIYers. Every calculation runs locally in your browser — nothing you type is uploaded or stored. We are not a shop and we do not earn commissions on the materials you buy; the numbers are there to help you plan and budget before you head to the store.

The specs (tile coverage, plank sizes, cubic-yard conversions) are standard industry figures. They are a planning aid, not a substitute for a contractor’s on-site measure, especially for structural work like decks and retaining walls.
