"How many tiles do I need?"
Counts come from the layout result (with cuts), then convert to boxes based on pack size.
Tile planning from a physical layout
Tile piece counts from layout
Certainty. From floorplan to floor. Plan grout-aware layouts, adjust centering to avoid edge slivers, and get box counts from the actual cut pattern for any room shape.
Calcufloor is a layout-based flooring piece count calculator for tiles. Set tile size, grout spacing, and centering, then place tiles digitally, include cuts, and count the resulting pieces.
Plan tile layouts and calculate exact tile 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 grout spacing, centering, diagonals, offsets, and edge cuts 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 tile 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?"
Start with the layout-driven count (cuts included). Then add your buffer for breakage and future repairs.
Diagonal and offset waste
Diagonal runs and offsets change the cut pattern at the perimeter. The preview shows the resulting cut layout.
How it works
Three steps. Set spacing and centering, place tiles digitally, include cuts, then count the resulting pieces.
1
Define the space
Define the room shape. Add cutouts where needed.
2
Enter tile details
Enter tile size, grout spacing, and layout choices (straight, diagonal, 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
Set tile size and grout spacing, then review centering and perimeter cuts before ordering.
Common tile questions
Short answers, written to match how people actually ask.
Is 10% extra tile enough, or should it be 15%?
Start with the layout-driven count (cuts included). Then add your buffer for breakage, dye-lot risk, and future repairs.
How much extra tile should I order for a diagonal layout?
Diagonal layouts create more edge cuts. Preview the layout, take the count from the cut result, then add your buffer.
How do I estimate tile for L-shapes, tapers, niches, and hearths?
Model the space you will actually tile, then simulate the layout so cut lines are visible and counts come from the cut result.
How much waste for 12×24 tile with a 50% offset?
A 50% offset changes the cut pattern at the perimeter, especially in small areas. Run the layout and take the count from the cut result.
How many spare tiles should I keep after the job?
Keep spares for future repairs and lot matching, especially for special-order or discontinued lines.
Start a tile plan
Open the tool and get a count derived from the layout (cuts included). Then add your buffer.
Tile layout → piece count
Counts are derived from the layout, including cuts.
