Measure the room once and get the tiles, boxes, spare tiles, trim, adhesive and grout to buy.

Project name, saving and backup ↓

Measure each room once. Every material on this page is planned from these measurements.

Units

Changing a unit only changes how values are shown. Your measurements stay exactly as entered.

Feet and inches: type 12' 6", 12 6 (= 12 ft 6 in) or 12.5 (decimal feet). Inches alone: 30".

Restore a backup, and how saving works

Unticking the box deletes every project saved by the indoor calculators and the exterior paint calculator on this site from this browser. Browsers can also clear saved site data on their own (for example in private windows or when space runs low), so download a backup file now and then.

Everything on this page runs in your browser. Your measurements, prices and project names are not sent to our servers.

What this planner works out

The planner turns your room measurements and the figures on the tile box into the boxes to buy: floor tiles, wall tiles to the full height or to a set height, and tiled areas such as a backsplash (splashback). It also counts trim profiles and bags of adhesive and grout, for one room or several.

The result is a quantity estimate from your own numbers. It does not say whether a floor or wall is suitable for tiles, how to waterproof a shower or how to set out the first row.

What to measure

  • Floor: length and width of the room, or an L-shape. Door openings are not taken off the floor: the tiles usually run to the threshold.
  • Walls: the wall height, every door and window, and the tiled height if the tiles stop below the ceiling. For a window on a part-height wall the planner also asks for its sill height, the distance from the floor to the bottom of the window.
  • Tiled areas: any rectangle measured on its own, such as a backsplash, a boxed-in pipe or the reveals of a window. Add them in step 1 and choose a tile for them in step 2.
  • From the box: the tile size, tiles per box or area per box, and the price.

The method

  1. Area: floor area, wall band (perimeter × tiled height, minus the part of each opening inside the band) and tiled areas, added up for every room that uses the same tile.
  2. With allowance: area × (1 + allowance). The allowance covers cuts and breakage.
  3. Tiles: area with allowance ÷ tile size, rounded up to whole tiles.
  4. Boxes: tiles ÷ tiles per box (or area ÷ area per box), rounded up. Boxes are never rounded down.

Worked example: a floor

A floor 3.6 × 3.0 m is 10.8 m². The tiles are 300 × 600 mm (0.18 m²), 6 per box.

  • No allowance: 10.8 ÷ 0.18 = 60 tiles, 60 ÷ 6 = 10 boxes
  • 10%: 11.88 m² ÷ 0.18 = 66 tiles, 66 ÷ 6 = 11 boxes
  • 11%: 11.988 m² ÷ 0.18 = 66.6, so 67 tiles, 67 ÷ 6 = 11.17, so 12 boxes: 72 tiles, 5 of them spare

Worked example: a bathroom tiled to 1.2 m

A room 2.0 × 1.8 m (perimeter 7.6 m) with 2.4 m walls, tiled to 1.2 m. The door is 0.8 × 2.0 m, the window 0.6 × 0.6 m with its sill at 1.5 m.

  • Band: 7.6 × 1.2 = 9.12 m²
  • Door: it starts at the floor, so 0.8 × 1.2 = 0.96 m² is inside the band
  • Window: it starts at 1.5 m, above the band, so nothing is taken off
  • Net: 9.12 − 0.96 = 8.16 m². With 250 × 400 mm tiles (0.1 m²), 10 per box and 10%: 8.976 m², 90 tiles, 9 boxes

With the sill at 1.0 m, 0.6 × 0.2 = 0.12 m² of the window is inside the band: 8.04 m², 89 tiles, still 9 boxes. If you leave the sill empty, the window is not taken off and the planner says so.

A trim along the top of the tiles runs 7.6 − 0.8 = 6.8 m, because only the door crosses the 1.2 m line. With 2.5 m profiles that is 2.72, so 3 profiles.

Worked example: a backsplash

A backsplash 3.0 × 0.6 m is 1.8 m², and the room around it needs no other measurements. Tiles 100 × 300 mm, 18 per box, 10%: 1.98 m² ÷ 0.03 = 66 tiles, 66 ÷ 18 = 3.67, so 4 boxes with 6 tiles spare.

Worked example: adhesive and grout

For a floor of 4.2 m² and an adhesive bag that says 4.0 kg per m²: 4.2 × 4.0 = 16.8 kg, so one 20 kg bag. At 5.0 kg per m² it is 21 kg, so two bags. Grout at 0.5 kg per m²: 2.1 kg, so one 2.5 kg bag. These figures are examples; use the ones on your products.

The planner opens with an example in feet and inches: a 12 × 10 ft floor with 12 × 24 in tiles, 8 per box, gives 66 tiles and 9 boxes, and walls tiled to 48 in with 4 × 12 in tiles, 30 per box, give 536 tiles and 18 boxes.

Joints

Joint width is optional and never changes the boxes to buy. With a joint, the planner also shows a slightly lower joint-adjusted figure for reference.

Limits

  • No cut plan. Cuts, offcuts and setting out are covered only by your allowance.
  • Herringbone, chevron and versailles patterns and decorative borders are not covered.
  • Batches. Buy all boxes from one batch and keep a few spare tiles for repairs. Tiles from different batches are separate materials in the planner.
  • Not part of this plan: waterproofing and wet-room systems (follow the system maker), the substrate, priming and leveling, underfloor heating, movement joints, the weight of tiles on a wall, and falls to a drain.

Cutting and grinding tiles makes silica dust, and old floor tiles and their adhesive can contain asbestos: do not break them up before checking. In the United States, see OSHA’s crystalline silica page and the EPA’s asbestos information; in Great Britain, see the HSE’s asbestos pages and its guidance on dust from cutting. In other countries, check your national guidance. To paint the walls above the tiles, tick Keep my projects on this device (or download a backup), then use Open project in the room refresh planner (or restore the backup there) and add paint for the same rooms.

Frequently asked questions

Can I plan sealant along the tiles?

Yes. Once wall or floor tiles are planned, open Plan other materials in step 2: the Sealant and filler group offers the edge of the tiled floor and, when the wall tiles stop below the ceiling, their top edge as lines, rounded up to whole cartridges.

Why does the laying pattern not change the number of boxes?

The pattern only adds cuts, so the planner keeps it as a label and you set the waste allowance yourself: diagonal and brick layouts usually need more than straight ones. The 10% shown is an example.

Why are doors and windows taken off for tiles but not for wallpaper?

Tiles are bought by area and cut one by one around an opening, so the area of a door or window really is not tiled. Wallpaper is hung in full-length strips. If you would rather keep the opening area as spare, untick Deduct doors and windows for that wall.

The box says both tiles per box and square meters per box. Which should I use?

Use tiles per box if the label gives it; it also shows the spare whole tiles. Labels often round the area, so the planner only warns when the two figures differ by more than 1%.

How many spare tiles should I keep for repairs?

There is no fixed rule, so the planner does not add spare tiles on its own. With tiles per box it shows the Spare whole tiles: the tiles in the boxes you buy minus the tiles the area needs, such as the 5 spare in the floor example above. If you want more for later repairs, raise the allowance or add a box, buy them with the rest so they come from the same batch, and keep a box label.

How many packs of peel-and-stick tiles do I need?

Choose Self-adhesive sheets as the product type of a tile in step 2, then type the sheet size, the overlap per edge from the instructions (0 if the sheets butt together) and the sheets per pack. The area plus the extra is divided by the area one sheet covers after the overlap, then rounded up to whole sheets and whole packs: a 10 ft² backsplash with 10% extra and 10 × 10 in sheets needs 11 ÷ 0.694 = 15.84, so 16 sheets, or 3 packs of 6 with 2 sheets left. No adhesive or grout is counted. Check the maker’s guidance for use behind a stove.

How many bottles of grout colorant do I need?

Add a Grout colorant in the tile section of step 2 and choose it for the floor, the walls or the tiled areas; it needs no tile entry, because the tiles are already there. Type the area one bottle covers per application and the number of applications from the label. That figure is for the tile and joint size printed with it: smaller tiles or wider joints use more, and some labels give a chart, so use the line for your tile. A 120 ft² kitchen floor plus 30 ft² of backsplash, 250 ft² per bottle, 2 applications and 10% extra needs 330 ÷ 250 = 1.32, so 2 bottles. Wear what the label asks for and ventilate.

Where do the adhesive and grout figures come from, and how do I enter mosaic sheets?

Only from you: type the kg per m² (or lb per ft²) from the bag or the maker’s chart, and if it gives a range, use the higher number. For mosaic tiles on a mesh, enter one mesh sheet as one tile, with the sheet size and sheets per box from the box. For grout, read the chart line for the size of the small pieces and your joint, not the sheet, because many small joints use much more grout.

How many tile spacers or leveling clips do I need?

The planner does not count them. Multiply Whole tiles needed from the result by the clips per tile from the clip maker’s chart, then divide by the pieces per pack and round up. For the 3.6 × 3.0 m floor above (66 tiles) at an example 4 clips per tile, that is 264 clips: 3 packs of 100.

How many interlocking garage floor tiles do I need?

Enter the garage floor as the floor of a room and add a Tile with the size of one tile and the tiles per box, with no adhesive or grout. A 20 × 22 ft floor (440 ft²) with 12 × 12 in tiles, 10% and 24 per box needs 484 tiles: 21 boxes. Edge ramps go in as a Tile trim with Trim, length typed in, using the length of one ramp piece as the profile length; cut tiles at walls and posts are covered by your allowance.
