How many tile that are 18 inches x 18 inches to cover 163 sq ft?

Answer 1

How do I figure a room for 18X18 tiles?

The concept is confusing but the math is pretty simple...

• Tiles are sold by the square foot not by the tile..
• Measure the room & round up to the next foot, ie.. 11' 6" just write it down as 12'
• If the room has offsets or halls, just remember to treat it like another room & do the length X width of each area. Then add them all up.
• Box will tell you how many sq feet is in a box, so you are paying by the foot, but buying by the box........
• Each 18X18 tile is 2.25 sq feet
• 163 sq ft divided by 2.25= the number of tiles you will need
• 16X16 tile will likely be packaged in a box with 9-11 pieces per box..
• Usually about 14- 18 sq feet per box depending on the makers preferences...
• By way of example if your room is 12X12 that's 144 sq feet,
• Divide the sq feet by how many sq feet in the box & you know how many boxes..
• Add about 7-10% to make sure you have enough....

Soooo once you know the sq feet you need, add a little for waste & breakage & ooops cuts & you will have enough..

The fact that a good tile setter starts in the middle of the room & works out also means you may have a fair bit of cutting one all the walls but a centered look is much better and likely allows you to use the pieces up.
