Measure your rooms
Add each rectangular room, its wall height and opening schedule. The estimator clearly shows gross walls and deducted net walls.
UTILITY TOOLS / CONSTRUCTION PLANNING
Construction Quantity Estimator
From room dimensions to a clear materials schedule. Estimate surfaces, tiles, paint and concrete with your own waste allowances, packaging and rates.

The previous saved data is still untouched. Download a copy before clearing it. Autosave is paused.
TOTAL FLOOR AREA—Gross rectangular footprint
NET WALL AREA—After opening deductions
TILES TO BUY—Includes wastage
CONCRETE ORDER—Wet volume + wastage

Room measurements

No rooms yet
Add a room to begin calculating areas and quantities.
Doors & windows
Deduct openings from wall surfaces. Dimensions are per opening.
Include in estimate
Switch off surfaces or a slab for rooms that don't need them.
All rooms use the same material assumptions. The grand total pools tile boxes and paint cans for project-wide purchasing; individual room rounding is also shown.
Wastage sensitivity
Compare ±5 percentage points of allowance. This is not a statistical confidence interval.

Planning limitation: This tool uses rectangular room geometry and nominal material consumption. It does not account for wall thickness, structural drawings, cut-pattern complexity, plaster, primer, reinforcement, local measurement standards, or construction-code compliance. Confirm the measured scope and supplier data before purchasing; do not use the nominal mix calculator to specify structural concrete.
