How Plank Flooring is Packaged and Sold
Hardwood, bamboo, engineered timber, and Luxury Vinyl Tiles (LVT/LVP) are sold in standardized carton boxes. You cannot buy a fraction of a box. The calculation follows:
Net Floor Area = Room Length × Room WidthGross Area = Net Floor Area × (1 + Wastage Percentage)Carton Boxes to Order = Gross Area ÷ Coverage Per Box (Rounded Up to Whole Box)
Recommended Wastage Allowance by Pattern
| Plank Layout Pattern | Recommended Wastage | Skill Level Required |
|---|---|---|
| Straight Parallel Run (Staggered Seams) | 8% to 10% | Beginner DIY Friendly |
| Diagonal (45-degree angle to walls) | 15% | Intermediate (Extensive wall cuts) |
| Herringbone or Chevron Parquet | 18% to 20% | Experienced Master Carpenter |
The Crucial Perimeter Expansion Gap
Natural wood and high-density fiberboard (HDF) expand and contract with seasonal ambient humidity shifts. If installed tightly against drywall, the floor will buckle, cup, or tent upwards within 12 months.
Installer Rule: Always insert 1/4-inch to 3/8-inch (6 to 10 mm) spacers along every wall, doorway jamb, and pillar. This expansion gap is completely hidden once baseboards and shoe moulding (quarter-round) are attached to the walls.
