WhereToCut.com

Define the room. Add the boards. Create a cut plan.

Select a room shape, enter its boundary dimensions and confirm the flooring values. WhereToCut checks the room, compares both board directions and creates a traceable row, source-board and saw schedule.

Step 1

Room boundary

Room model Rotate model

Horizontal closureE 0 mm = W 0 mm

Vertical closureN 0 mm = S 0 mm

Boundary edges in anticlockwise walking order
Segment	Walk	Edge	Length

Enter measurements in your selected display units. Imperial values are converted once to the nearest millimetre for calculation. The preview remains visible when the boundary is open or crosses itself so the problem can be corrected visually.

Step 2 · Flooring inputs

Use the installed dimensions stated by the manufacturer. Tongue-and-groove face width excludes the projecting tongue.

Board lengthmmMeasure from flat end to flat end. Board face widthmmFor T&G, enter installed coverage width and exclude the projecting tongue. Board edge profileT&G means tongue on one long side, groove on the other and flat ends. Expansion gap at every fixed edgemmA 10 mm setting means 10 mm at every wall or obstruction, not 10 mm in total. Smallest usable piece lengthmmNo installed starter, middle or end piece may be shorter. Minimum installed board widthmmEvery installed rip strip and retained width beside a notch should meet this value where possible. Minimum end-joint stagger between adjacent rowsmmInternal end joints in neighbouring rows must be at least this far apart along the board direction. Manufacturer instructions take precedence.

Cutting settings

Kerf is the width of material removed by the saw blade. WhereToCut keeps each required piece at its finished size and takes kerf from the offcut side.

Saw kerfmmTypical blades remove a few millimetres. Enter the blade width used for this job. Kerf calculationIgnore saw width and calculate with 0 mm kerfYour entered kerf is remembered and restored when this option is switched off.

Select a model or edit an edge to begin.

WhereToCut calculation

WhereToCut calculates the optimal layout for both board directions and returns a complete cutting plan.

Verify every plan against the flooring manufacturer's installation instructions before cutting.

Validate the room and flooring input, then calculate the plan.

Installation schedule

Rows and installed boards

Rows are listed in course-progression order. Every piece refers to its source board and cut IDs.

Row / run	Width	Run & joints	Installed pieces	Required cuts

Stock schedule

Full source boards

Crosscut marks are cumulative from the chosen factory end. Each shaped piece also lists its rip, notch and reused-offcut operations.

Each entry includes a simple diagram showing the cut line and the side from which kerf is consumed.

Every expected remnant is listed. Pieces below 100 mm in either dimension are shown compactly without a diagram.
