# How to Calculate Tiles Needed for a Floor

**To determine the number of tiles required for the given floor, here are four simple steps**

*Note: Door Size = 2.1 m × 0.9 m*

### STEPS ON HOW TO CALCULATE TILES NEEDED FOR A FLOOR

**STEP 1**

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 m^{2}

**STEP 2**

Calculate the perimeter of the room, to find skirting tiles requirement,

From the above image 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 the skirting tiles height.

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

= 13.1 m × 0.1016 m

= 1.33 m^{2}

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

= 12 m^{2} + 1.33 m^{2}

**Total Area to be laid = 13.33 m ^{2}**

**STEP 3**

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) m ^{2}**

**STEP 4**

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 m^{2} / 0.09 m^{2}) + 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.

Assuming 1 box contain 17 tile pieces, then

Number of boxes = 156/17 =** 9.2 boxes of tiles**
