Carpet Quantity Calculator
Carpet is sold by the square yard (sq ft / 9), with waste added for seams and pattern matching. Note the 12 ft standard carpet roll width when planning seam placement.
Countertop Area Calculator
Countertop area = sum(segment length ft x standard depth ft) - cutout deductions (sink/cooktop), plus optional backsplash area (linear ft x height in / 12). Standard depth default is 25 in (≈2.08 ft).
Flooring Quantity Calculator
Boxes = ceil(area x 1.10 waste / sq ft per box), the standard flooring takeoff approach used for tile, laminate, vinyl, and engineered wood.
Hardwood Flooring Calculator
Order quantity = area x waste factor (10% standard layout, 15% diagonal layout), the standard hardwood flooring takeoff approach.
Laminate Flooring Calculator
Laminate flooring waste: 10% standard straight layout, 15% for diagonal layout, per standard flooring installation guidance.
Patio Paver Calculator
Paver count = ceil(patio area x 1.10 waste / single paver area), where single paver area = (length in x width in) / 144.
Paver Sand Calculator
Standard paver bedding sand layer is a 1-inch compacted depth: sand volume = patio area x (bedding depth in / 12) x 1.10 waste.
Tile Adhesive Calculator
One 50-lb bag of thinset/tile adhesive typically covers 40-50 sq ft with a 1/4 in notch trowel; this calculator defaults to the 45 sq ft/bag midpoint, adjustable.
Tile Grout Calculator
Uses the industry-standard trade formula: grout lbs = ((tile length in + tile width in) / (tile length in x tile width in)) x joint width in x joint depth in x 0.121 x area sq ft. Joint depth defaults to tile thickness.
