# How do you Calculate the Number of Floor Tiles you Need?

Normally, We calculate the tile flooring area in order to find the required number of the tiles for a given room. Assuming that situation, we have explained this post with an example.

If you are looking for complete cost estimation, Tile Flooring Cost Estimation post will help you.

Let’s Start.

# How to Calculate Tiles needed for a Floor?

For better illustration,

we have separated the calculation in Square meters and Square foot.

## Tile Flooring Calculation in Square Metres (Figure . A)

To determine the number of tiles required for the given floor (Fig. A),

Note: Door Size = 2.1 m × 0.9 m

Figure A

• First, multiply the length and breadth of that room to get the area

Total Room Floor Area = Length of the room × Breadth of the room

= 4 m × 3 m

= 12 m2

• Second, calculate the perimeter of the room, to find skirting tiles requirement,

From the above image (Fig. A), we can find the perimeter as

Perimeter of the room = (4 m + 3 m + 4 m + 3 m) – Door Width

= 14 m – 0.9 m

= 13.1 m

We have assumed 0.1016 m (4 inches) as skirting tiles height.

Skirting Tiles area= Perimeter of the room × Skirting Tile height

= 13.1 m × 0.1016 m

= 1.33 m2

Total Area to be laid  = Total Floor Area + Skirting Tiles area

= 12 m2  + 1.33 m2

Total Area to be laid  = 13.33 m2

• Third, calculate the area of one tile that we are planning to lay on that floor, Here We are going to use 0.3 m × 0.3 m (or 300 mm × 300 mm) tiles,

Area of one tile = 0.3 m × 0.3 m

= 0.09 (approx) m2

• Finally, the total number of tiles required for the above room is,

Number of Tiles required = (Total Area to be laid / Area of one tile) × Wastage*

= (13.33 m2 / 0.09 m2) × 5%

= 148.1 + 7.41 tiles

Number of Tiles required = 156 tiles (Approx)

*Wastage – Rendered wastage & damaged tiles

Therefore, we need 156 tiles, for the above room.

You can make use of the below calculator,

### Tile Flooring Calculator (In Square meters)

Note: We have not included the option of the door opening for simplicity of the tool. So please calculate the openings and exclude from your calculation.

## Tile Flooring Calculation in Square Foot (Figure . B)

To determine the number of tiles required for the given floor (Fig. B),

Note: Door Size = 7 ft × 3 ft

Figure B

• First, multiply the length and breadth of that room to get the area, where you need tile laying

Total Room Floor Area = Length of the room × Breadth of the room

= 12 ft × 9 ft

= 108 sq.ft

• Second, calculate the perimeter of the room, to find skirting tiles requirement,

Related : Why do we need skirting tiles?

From the above image (Fig. A), we can find the perimeter as

Perimeter of the room = ( 12 ft + 9 ft + 12 ft + 9 ft ) – Door Width

= 42 ft – 3 ft

= 39 ft

We have assumed 4 inches as skirting tiles height.

Skirting Tiles area       = Perimeter of the room × Skirting Tile height

= 39 ft × 0.33 ft

= 12.87 Sq.ft

Total Area to be laid  = Total Floor Area + Skirting Tiles area

= 108 Sq.ft + 12.87 Sq.ft

Total Area to be laid  = 121 Sq.ft

• Third, calculate the area of one tile that we are planning to lay on that floor, Here We are going to use 12“ X 9” inch (or 12 inch X 9 inch) tiles,

Area of one tile = 12” × 9”

= 1 × 0.75

= 0.75 Sq.ft (approx)

• Finally, the total number of tiles required to be order for the above room is,

Number of Tiles required = (Total Area to be laid / Area of one tile) X Wastage*

= (121 Sq.ft / 0.75 Sq.ft) × 5%

= 161.33 + 8.06 tiles

Number of Tiles required = 169 tiles (Approx)

*Wastage – Rendered wastage & damaged tiles

Therefore, we need 169 tiles, for the above room.
