Area is not a cut pattern
Two spaces with the same area can produce different edge cuts and different ordering needs.
Flooring quantities from the layout, not assumptions
CalcuFloor calculates tile and plank flooring quantities from a generated layout — not
an area formula. Piece counts include every perimeter cut for the room shape you define.

Why layout-based counts are more accurate than area plus a percentage
Area does not show the cut pattern at the perimeter. Quantity is driven by room geometry and layout choices such as direction, offset or stagger, and start position. See how the layout is generated if you want the mechanism.
Cuts drive quantity
The simulated layout shows where cuts occur and how much of the material becomes cut pieces.
Edge balance matters
Start/end row widths can be adjusted to avoid narrow edge strips that look bad and are harder to install cleanly.
Scope
Boundary clarity.
In scope
Layout simulation, cut visibility, layout-derived piece counts, and manual edge-width adjustment.
Out of scope
BIM, takeoff suites, estimating services, and manufacturer install requirements.
When to use CalcuFloor instead of a standard overage estimate
Use it when you need to see edges, cuts, and first or last rows before you order, and when a standard percentage does not tell you enough.
After the estimate
If you already have an m² number, use CalcuFloor to see the layout outcome and derive counts from the cut result.
When edges matter
Adjust the layout offset to compare start and end rows, avoid narrow strips, and review the perimeter result before you order.
When the room is not a rectangle
Any room shape with cutouts. The layout adapts to the geometry instead of forcing the geometry into rectangles.
What makes CalcuFloor different
CalcuFloor is built for serious floor layout planning. It is intended for professionals and advanced DIY installers who need a usable layout, accurate quantity logic, and project continuity.
Actual layout calculation
The pieces shown in the layout are the pieces used for the calculation. Counts are derived from the generated layout itself, including cuts, edges, row starts, and perimeter outcomes, not from surface area plus a percentage.
Built for real jobs
CalcuFloor supports planning before ordering and before installation. Layout Reports can be used for client review, quoting, and installation reference, so the same layout can carry through the job instead of being reinterpreted later.
Project persistence
Projects, layout settings, quantities, and reports stay attached to the same job. That makes it useful for ongoing work, revisions, and returning to a layout later, rather than using a disposable one-off calculator.

Calculated from Layout Geometry
not arbitrary guesswork
Calepinage is the planning step before tile, stone or floorboard installation. It defines the pattern, starting line, joint placement, edge cuts, quantities and surplus before the first cut is made.
CalcuFloor is built around that same working method. Instead of estimating from area alone, it generates the layout from the real room shape, real product size, real joint width, real cuts and real site quantities.
Calepinage 15th-Century
in milliseconds
The word calepinage comes from calepin, a small notebook used for notes and sketches. The older root traces back to Ambrogio Calepino, a 15th-century Italian monk whose dictionary became so widely used that his name entered everyday language.
In the trade, the meaning became practical: the layout sketch made before installation. CalcuFloor keeps that logic, but makes it live, measurable and adjustable before materials are ordered or work starts.

Common questions
Concise answers.
What is CalcuFloor?
A layout-based flooring piece count calculator for tiles and planks. It generates the
layout, includes cuts, and derives counts from the result.
Who is it for?
Installers, contractors, and DIY users who need layout-based piece counts and a clear view
of perimeter cuts.
Do I need an account or email?
No. Results are available immediately. No account. No email.
How is this different from "m² + 10%"?
A fixed overage percentage does not reflect the cut pattern created by the layout.
CalcuFloor derives counts from the generated layout outcome instead of applying an area
multiplier.
Does it work for any room shape?
Yes. You define the room as its real outline and add cutouts. It is not limited to
rectangles, L-shapes, or U-shapes.
Does CalcuFloor tell me the "correct" waste percentage?
No. CalcuFloor shows the cut outcome from the layout. You set the final buffer for breakage,
defects, and future repairs.
Does it replace manufacturer installation rules?
No. Follow manufacturer requirements first. CalcuFloor is for layout planning and ordering
counts derived from that layout.
Does CalcuFloor work for both tiles and planks?
Yes. Tiles and planks are handled by separate layout implementations. Each mode shows the
patterns, controls, and outputs relevant to that material.
