HOW TO CALCULATE TILES NEEDED FOR A FLOOR AND WALL?
In this article, we will explain how to calculate the quantity of tiles needed for your floor or wall construction.
Note: This
Calculation Will Be In Square Meters Or Meters
Example:
Consider this plan as a Given data
In
figure we have floor size of 12m x 12m
We
want To determine the number of
tiles required for the given floor area
Number of Tiles required = (Total Area to be laid / Area of one tile) × Wastage
STEP 1: Find Total Area To Be Laid
Total area = Total Room Floor Area + Skirting Tiles area
Total Room Floor
Area = Length
of the room × Breadth of the room
Length of the room = 12m – (2 x thickness of outer wall) = 11.4m
Breadth of the room = 12m – (2 x thickness of inner wall) = 11.4m
Total Room Floor Area = 11.4m x 11.4m = 144m^{2}
^{}
Deductions
Column = 0.9 x 0.9 = 0.81m^{2}
Wall area = (4+2+2.8+0.8) x thickness of inner wall = 9.6 x 0.15 = 1.44m^{2}
Total deductions = 0.81m^{2 }+ 1.44m^{2 }= 2.25m^{2}
Total Room Floor Area = 144 + door side area – deductions = 144 + (1.5x0.3) – 2.25 = 142.2 m^{2}

Skirting Tiles area: To know the skirting tiles needed we need to calculate the perimeter of the floor
From the above image plan, we can find the perimeter as
0.3 wall = 11.4 + 11.4 + 11.4 + 11.4 – (door opening 1.5) = 44.1Rm
0.15 wall = (outer side + inner side) = (2.8+0.8+2+4) + (2.65+0.65+1.85+3.85)
= 18.6Rm
Column = (length x 4 sides) = 0.9 x 4 = 3.6Rm
Total perimeter of the floor = (44.1+18.6+3.6) = 66.3Rm
We will take 0.1016 m (4
inches) as skirting tiles height
Skirting Tiles
area= The perimeter of the room × Skirting Tile height
Skirting Tiles area= 66.3 x 0.1016 = 6.73 m^{2}
^{}
Total area = Total Room Floor
Area + Skirting Tiles area
Total area = 142.2 m^{2 }+ 6.73 m^{2 }= 148.93 m^{2}
^{}
STEP 2: Find Area Of Tile
Calculate the area of a tile that we plan to place on the floor, where
we will take 0.6 m × 0.6 m or 600 mm × 600 mm as tile size,
Area of one tile = 0.6 m × 0.6 m
Area of one tile = 0.36 m^{2}^{ }(approx)
STEP 3: Number Of Tiles Required
Number of Tiles required = (Total Area to be laid / Area of one tile) ×
Wastage*
Number of Tiles required = (148.93/0.36) + 2% = 413.69
+ 8.27 = 421.96 – 425 tiles
Number of Tiles required = 425 tiles
*Wastage – Rendered wastage
& damaged tiles
