Floor Planner and Flooring Calculator

1. Draw the room. Start from a rectangle or an L-shape, or click round the room corner by corner. Type each wall's length as you go, drag corners and walls to adjust them, and add cutouts for a hearth, island or column, and doorways on the walls.
2. Add your floor. Enter the plank or tile size, how many come in a pack and the price. Add underlay, adhesive and grout if the job needs them.
3. Choose the layout. Planks can start each row with the last row's offcut, at a set offset, or at random. Tiles can be a grid or a brick bond, centred or from a corner. Herringbone works for planks, blocks or tiles. Set the direction, the shortest end piece, the joint stagger and the expansion gap, and drag the pattern to move it.
4. Read off the quantities. You get the packs to order with your spare, how much isn't laid, skirting lengths, underlay rolls, adhesive bags and grout, with a cost ex VAT and inc VAT. Add more rooms with the same floor, and offcuts carry on from room to room.
5. Save it. Download the cutting list as a CSV, or save the project file to open again later or on another computer.

How it works out the quantities

It lays every piece in the room, row by row, and cuts each one from a new plank or tile, or from an offcut big enough to use. Planks keep track of which end is factory-cut, so a starting piece only comes from an offcut that still has a factory end. Packs are the pieces used plus your spare, rounded up to whole packs.

Grout uses the usual formula: (tile length + tile width) ÷ (tile length × tile width) × tile thickness × joint width × grout density, per square metre.

The planner is a guide for estimating and setting out. Always follow the floor maker's fitting instructions for gaps, end lengths and stagger.
