How many 20x20 square inch tiles dose it take to cover 56 square feet?
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 16X16 tile is 1.778 sq feet
- 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....
- THE FORMULA IS : area divided by sq ft per tile ie 225 sq feet of 18X18 tiles would take 10 tiles....
- 12X12 is DUH 1 sq foot
- 13X13 is 1.174
- 18X18 tiles are 2.25 sq ft per tile
- 20"x20" tiles are 2.778 per tile
- 24X24 tiles are 4 sq ft per tile
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.

1070 square feet is 154080 square inches. (1 square foot is 12x12 or 144 square inches.) a 20x20 inch tile is 400 square inches. So the question could be restated as "how man…y 400 square inch tiles does it take to cover 154080 square inches?" 154080 / 400 = 385.2
20X20" tiles are 1.67'X1.67' giving a total sq ft per tile of 2.8 s/f 100 tiles would cover 280 sq feet so looks like 97 tiles gets you to 272. we always recommend about …5-7% overage to allow for a broken tile or a bad cut.
550 sq feet = 550*12*12 = 79200 sq inches. 20"x20" = 400 sq inches. So number of tiles required = 79200/400 = 198 That is the mathematical answer. It assumes that the …550 square feet shape is such that every offcut can be reused (not so easy if it is 550 sq feet in a circular shape!), that you cut every tile perfectly, there are no breakages, etc. In real life, depending on your level of skill, get at least 5% more tiles.
500 sq feet = 500*12*12 = 72000 sq inches Each tile is 20*20 = 400 sq inches So, number of tiles required = 72000/400 = 180 This assumes that either the shape is such that on…ly whole tiles are required or that all offcuts are used.
How many 20X20 tiles If this is homework the answer looks like this . 20X20= (sq inches per tile) Â¨ Sq Inches per tile divided by 144 = (sq feet per tile) (A…bout 2.8 sq ft per tile) but do your own math, that's what a cell phone calculator is for, . divide 400 by sq feet per tile= your # of tiles needed If this is the real world there are grout lines, miscuts & broken tile & undersized tiles to consider, ask the guy at home depot to figure it.. I would expect. 140-160 tiles on your cart at check out
20" = 2.78 square feet. Now divide the area of the tiles into the area of the room. 140/2.78 = 51 tiles
440 6-inch square tiles.
Assuming they are 20 by 20 inches, then the area of a tile is 400 feet 2 /144. 200 feet 2 /(400 feet 2 /144) = 72
Area of each tile = 20*20 sq inches = 400 sq inches. Area to be covered = 1744 sq ft = 1744*144 = 251136 sq inches. So minimum number of tiles required = 251136/400 = 627.8 i…s 628 tiles. That is the mathematical answer which assumes that almost all the offcuts can be used. If the area to be covered is odd shaped there will be a lot of offcuts that cannot be used unless you want a mosaic effect!
a 12 x 2 inch square tile is 1 foot by foot = 1 sq ft you need 252 tiles
Since each 12x12-inch tile is one square foot, you will need 750 ofthem.
20 inches = 20/12 ft = 1.67ft 6 inches = 6/12 ft = 0.5ft 1.67X0.5 ft = 0.83 sq ft. Therefore 900sq ft / 0.83 sq ft = 1080 tiles However the above answer …is how much is needed without waste. I.e. no partial tiles for the perimeter.
18 10x10-inch tiles.
If that is 60" tiles it would take 16 total.
Area to be covered = 25 sq ft = 25*12*12 sq inches = 2600 sq inches. So minimum number of tiles required = 3600/(16*16) = 14.06 is 15 tiles. However, that assumes that there… is almost no wastage - a very unlikely assumption.
