Reference tables
Look-up charts built from stable conventions — installed cost bands per sq ft by material, waste factor by layout pattern, box coverage and common plank/tile sizes, grout and thinset coverage, underlayment/leveler/vapor coverage, and expansion gap and acclimation time by material.
Typical industry planning values. These are typical planning values — confirm against the manufacturer’s install instructions and your product’s spec sheet.
Flooring cost per sq ft by material (installed)Typical installed cost bands per sq ft by material (hardwood, engineered, laminate, vinyl/LVP, tile, carpet, epoxy), as labeled PLANNING bands — a sanity guide behind the cost tools.Flooring waste factor by layout patternTypical waste % by layout pattern (straight ~10%, diagonal ~15%, herringbone/chevron ~15–20%), as labeled planning values — behind the flooring and waste-factor tools.Box coverage and common plank & tile sizesTypical box coverage (~20 sq ft) and common plank and tile sizes, as labeled conventions — behind the flooring, plank/box and tile calculators.Grout and thinset coverage by tile size & trowelTypical grout coverage (lb/sq ft by tile size + joint) and thinset coverage (sq ft per 50-lb bag by trowel notch), as labeled planning values — behind the grout and thinset tools.Underlayment, self-leveler and vapor-barrier coverageTypical underlayment roll coverage, self-leveler bag yield and vapor-barrier roll coverage, as labeled planning values — behind the subfloor & prep tools.Expansion gap and acclimation time by materialTypical perimeter expansion gap by material (laminate/LVP ~1/4"–3/8", engineered ~1/2", solid hardwood ~3/4") and acclimation time (48–72 h), as labeled planning values — behind the layout tools.
