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.
