This flooring calculator helps you determine how much flooring material you'll need for your project and estimates the total cost based on your selections.
How It Calculates
The basic formula is: Flooring Needed = Room Area × (1 + Waste Factor)
The calculator first determines the total area by multiplying length by width for each room. Then it adds a waste factor percentage to account for cuts, errors, and future repairs. Finally, it converts the total square footage to the appropriate units (tiles, planks, etc.) based on your selected flooring type.
About the Waste Factor
Including a waste factor is essential for any flooring project:
- 5-7%: Recommended for simple rectangular rooms with few obstacles
- 8-10%: Standard for most residential projects
- 12-15%: Recommended for complex layouts, diagonal installations, or patterned designs
- 15-20%: For intricate patterns, herringbone, or very complex room shapes
Tips for Accurate Measurement
- Measure each room at its widest points
- For L-shaped or irregular rooms, divide into rectangles and add them together
- Include closets and other alcoves in your measurements
- Don't subtract for permanent fixtures like kitchen islands unless they extend to the floor
