"How many planks do I need?"
Counts come from the layout result (with cuts), then convert to boxes based on pack size.
Plank planning from a physical layout
Plank piece counts from layout
Certainty. From floorplan to floor. Preview stagger/offset, diagonals, and first/last-row widths, then get box counts from the actual cut pattern — not an area guess.
Calcufloor is a layout-based flooring piece count calculator for planks. It places planks digitally, includes cuts, and counts the resulting pieces, then converts to box counts.
Plan plank layouts and calculate exact plank quantities based on a simulated physical layout—not just area. Preview cuts, diagonals, offsets, and awkward room shapes before you order.
Use the preview to check direction, diagonal runs, seam offset, and first/last-row widths before you order.
What this solves
These are the questions that keep coming up in real projects. The page is structured to match them directly.
Common decisions when planning a plank floor.
"Is 10% or 15% extra standard?"
Overage is driven by layout and room geometry. A layout preview shows the real cut waste before you commit to ordering.
"How much extra should I order?"
First get the layout-driven count (cuts included). Then add your own buffer for breakage and future repairs.
First/last row slivers
Shift the start position so first and last rows land at practical widths.
How it works
Three steps. Place planks digitally, include cuts, then count the resulting pieces.
1
Define the space
Define the room shape. Add cutouts where needed.
2
Enter plank details
Enter plank size and layout choices (direction, diagonal, seam offset).
3
Get counts from the layout
Piece counts from the layout result, with cuts visible. Use that to decide your buffer and ordering.
Layout preview
Adjust direction and start position to avoid thin first/last rows before ordering.
Common plank questions
Short answers, written to match how people actually ask.
Is 10% extra plank enough, or should it be 15%?
Start with the layout-driven count (cuts included). Then add your own buffer for breakage, dye-lot risk, and future repairs.
How much extra plank should I order for a diagonal layout?
Diagonal runs create more edge cuts. Preview the layout and take the piece count from the cut result, then add your buffer.
How do I avoid thin slivers on the first or last row?
Shift the start position so first and last rows land at practical widths. The preview shows those widths before you cut anything.
How do I estimate planks for L-shapes, tapers, closets, and odd angles?
Simulate the layout so cut lines are visible and piece counts come from the cut result, even with complex edges.
Should I stagger seams randomly or use a fixed pattern?
Follow manufacturer minimum stagger rules first. Then use the preview to confirm the seam offset you want across the room.
Start a plank plan
Open the tool and get a count derived from the layout (cuts included). Then add your buffer.
Plank layout → piece count
Counts are derived from the layout, including cuts.
