how to calculate the number of tiles needed for a room
First, we will calculate the number of tiles needed for a floor in an sq. m unit. (Unit of measurement is sq. m.). You can also use the above tile calculator.
Step- 1 Measure the Area of the Room or Floor
Take the length and width measurements of your room in the meter unit.
- Suppose, Length of the room floor is 10m and the Width of the room floor is 8m.
- It is a 10m x 8m Room.
Step – 2 Calculate the Area of the Room or Floor
The area can be calculated by just multiplying the length and width of the floor together.
So, Area = Length x Width = 10m x 8m = 80 sq. m.
Step – 3 Measure the Size of the Tiles
- Take measurements of the tile selected or propose to be installed in a given flooring area.
Let’s take size of tile is 0.30 m x 0.30 m (30cm x 30cm)
Step – 4 Calculate the Area of the Tile
The tile’s area can be calculated by just multiplying its length and width together.
Area of Tile = 0.60 m x 0.60 m = 0.36 sq. m.
Step – 5 Calculate the Number of Tiles Needed For a Floor
- Nos. of tiles required for a given floor area is calculated by diving the area of the floor by the area of one tile.
- Nos. of Tiles = Area of Floor / Area of One Tile
= 80 / 0.36 = 222 Nos.
Note: There are always chances of wastage because sometimes cutting is required in many areas. So, always consider at least 5 % wastage, while calculating the number of tiles needed for a floor.
Add an Extra 5 % Quantity of tiles for wastage compensation.
Nos. of Tiles = 222 + 5 % Wastage
= 222 + (222 x 0.05)
= 222 + 11 = 233 nos.

How to Calculate How many tiles I Need for the Floor?
Now, we will calculate the number of tiles needed for a floor in sq. ft unit. (Unit of measurement is sq. ft.)
Step- 1 Measure the Area of the Room or Floor
Take the length and width measurement of your room in feet units.
Suppose, Length of the room floor is 20 ft. and the Width of the room floor is 15 ft.
So, it is a 20 ft. x 15 ft. Room.
Step – 2 Calculate the Area of the Room or Floor
The area can be calculated by just multiplying the length and width of the floor together.
So, Area = Length x Width = 20 ft. x 15 ft. = 300 sq. ft.
Step – 3 Measure the Size of the Tiles
Take measurements of the tile selected or propose to be installed in a given flooring area.
Let’s take the size of the tile as 2 ft. x 2 ft. (24-inch x 24 inches)
Step – 4 Calculate the Area of the Tile
The tiles’ area can be calculated by just multiplying their length and width together.
Area of Tile = 2 ft. x 2 ft.= 4 sq. ft.
Step – 5 Calculate the Number of Tiles Needed For a Floor
- Nos. of tiles required for a given floor area is calculated by diving the area of the floor by the area of one tile.
Nos. of Tiles = Area of Floor / Area of One Tile
= 300 sq. ft. / 4 sq. ft. = 75 Nos.
Note: There are always chances of wastage because sometimes cutting is required in many areas. So, always consider at least 5 % wastage, while calculating the number of tiles needed for a floor.
Add an Extra 5 % Quantity of tiles for wastage compensation.
Nos. of Tiles = 75 + 5 % Wastage
= 75 + (75 x 0.05)
= 75 + 4 = 79 nos.

How to Calculate Skirting Tiles
Skirting quantity is generally measured in the running meter. So, for calculating the number of skirting tiles required to measure the running meter length of the room.
(Note: skirting is measured in running feet or running meter)
Take the size of the room is 10 m x 8 m.
Now, Measure the Perimeter or Running meter length of the room.
If you have the length and width of the room, then you can easily calculate the running meter of the room by just multiplying the length and width twice and summing it.
Running meter length of room = (2 x 10m) + (2 x 8m) = 36m.
- We have to deduct the length of the doors because skirting is not provided on the door option.
- Size of Door = 1 m x 2.1m, Length of door = 1 m.
- Actual Running meter length of Skirting = 36 m – 1 m = 35 m.
- So, 36 m is the running meter of the room on which skirting tiles are required to install.
How to Calculate Skirting Tiles For Room
In skirting tiles calculation, the number of skirting tiles can be calculated by just diving the running meter length of the room by the length of the skirting tile selected.
Suppose, skirting tiles size is 30cm x 7cm ( 0.30 m x 0.07 m)
In the above size of tile 0.30m length of tile and 0.07 m height the tile.
The number of Skirting Tiles = 35 m / 0.30 m = 116.66 Nos., Correct it = 117 m.
