About This Calculator

Straight layouts waste about 10%, diagonal patterns 15%, and herringbone 20%. Enter your room size, plank dimensions, and pattern to get a precise shopping list with estimated cost.
Frequently Asked Questions
How many boxes of flooring do I need?
It depends on your room size and plank dimensions. A standard box covers approximately 20-25 sq ft. Enter your room's square footage and plank size into our calculator for an exact box count including waste.
How much waste does herringbone flooring produce?
Herringbone patterns typically produce 20% waste due to the angled cuts at each row. Our calculator automatically adds this waste factor when you select the herringbone pattern.
What are standard flooring plank dimensions?
Standard hardwood planks are 3-5 inches wide and 12-48 inches long. Engineered wood planks are typically 5-7 inches wide and 48-72 inches long. Wide plank flooring can be 7-12 inches wide.
Should I buy extra planks beyond what the calculator shows?
The calculator already includes waste for your chosen pattern. However, keeping 2-3 extra planks is smart for future repairs. Flooring batches can vary in color, so matching later may be difficult.
