Flooring Material Coverage

Material Coverage per Unit Typical Cost/Sq Ft
Hardwood Board feet $8-15
Laminate Sq ft per box (20-30) $3-8
Carpet Sq ft per roll (varies) $2-10

Waste factor: Always add 10% extra for cuts and mistakes.

Example: Room is 12' × 15' = 180 sq ft

  • With 10% waste: 180 × 1.10 = 198 sq ft to purchase

Paint Coverage

Standard coverage: 1 gallon covers ~350-400 sq ft with one coat

Example: Room walls (12' × 15' × 8' ceiling)

  • Two long walls: 2 × (15' × 8') = 240 sq ft
  • Two short walls: 2 × (12' × 8') = 192 sq ft
  • Total wall area: 432 sq ft
  • Subtract windows/doors (~60 sq ft): 372 sq ft
  • One coat: 372 ÷ 375 = 1 gallon
  • Two coats: 2 gallons
