Laminate Flooring Calculator

Calculate how much laminate flooring to order, with an adjustment for a diagonal install layout.

Laminate Needed
— sq ft
Includes waste and layout.

Usage Tip

Round up to whole boxes when you buy, and keep one spare box for future repairs since product lines get discontinued.

THE MATH
order = area × (1 + waste ÷ 100) × (1 + diagonal bonus ÷ 100)
Laminate planks click together across the whole floor. A waste allowance covers cuts at the walls, and a diagonal layout wastes more at the angled edges.
Enter the floor area, a waste percentage (10 percent typical), and the install direction.
A diagonal layout adds 15 percent for the extra angled cuts.
