Let your flooring acclimate in the room for 48-72 hours before installation for best results.

How to Calculate Flooring Materials

Accurately estimating flooring materials prevents costly over-ordering or frustrating shortages mid-project. The process involves calculating your room's square footage, adding waste factor, and determining how many boxes or units you need based on the coverage per package.

Waste Factors by Installation Type

Installation Pattern Waste Factor Best For
Straight/Standard 10% Beginners, rectangular rooms
Diagonal (45 degrees) 15% Making rooms look larger
Herringbone 20% Classic, elegant look
Random Stagger 12% Natural appearance

Flooring Type Comparison

Type Price Range Lifespan DIY Friendly

Additional Materials Needed

  • Underlayment: Required for laminate and some vinyl; provides cushion and moisture barrier ($0.25-0.75/sq ft)
  • Transition Strips: Cover gaps between flooring types or rooms ($15-50 each)
  • Baseboards: Cover expansion gaps at walls (optional replacement)
  • Adhesive: Required for glue-down vinyl and some tiles
  • Grout: Required for tile installations
  • Spacers: Maintain expansion gaps during installation

Tips for Flooring Installation

  • Acclimate flooring in the room for 48-72 hours before installation
  • Always buy 10-15% extra for mistakes and future repairs
  • Keep leftover boxes for warranty claims and repairs
  • Ensure subfloor is level (no more than 3/16" variation per 10 ft)
  • Leave 1/4" to 1/2" expansion gap at walls
  • Stagger end joints by at least 6 inches between rows
  • Start installation from the longest, most visible wall
