HOW TO CALCULATE TILES NEEDED FOR YOUR ROOM
Many people either overbuy or underbuy tiles because they don’t know the simple method to calculate it. Let’s break it down step by step using a standard room size.
ROOM SIZE
Length = 3.6 m
Width = 3.0 m
First, calculate the FLOOR AREA
Area = Length × Width
Area = 3.6 × 3.0 = 10.8 m²
Now you know your room is 10.8 square meters.
Next, you need to know the SIZE OF YOUR TILE.
Let’s assume you are using a common tile size of 600 mm by 600 mm
Convert to meters
0.6 m × 0.6 m = 0.36 m² per tile
Now calculate NUMBER OF TILES
Number of tiles = Total area ÷ Area of one tile
= 10.8 ÷ 0.36
= 30 tiles
Now let’s convert to CARTONS
Most 600 by 600 tiles come 4 pieces per carton
Number of cartons = 30 ÷ 4
= 7.5 cartons
Since you cannot buy half carton, you round up
You will need 8 cartons
Now add WASTAGE
Always add about 5 to 10 percent for cutting and breakage
8 cartons + 1 extra carton = 9 cartons total
FINAL ANSWER
You need about 9 cartons of tiles for a 3.6 m by 3.0 m room
This method helps you plan properly and avoid wasting money.
