You calculate the sqft of the room, a sqft is still a sqft no matter what the tile dimensions are
I will not explain exactly how to tile but i will tell you that your floor has to be very flat, an 18" tile is harder to install when there are crowns in floor they are not as forgiving as a 12 or 13" tile and you will have unacceptable lippage in your 18" tile, for installing go to john bridges website.
The best way to figure out how many 13x13 tile will be needed to cover 30 sf of floor is to calculate 13x13/144 give coverage per tile (1.1736), then take 30/1.736 = 25.56 tiles.
I assume that the tile is a square of 13 inches by 13 inches. There are exactly 12 inches in 1 foot, so 13 inches is (13 inches)*(1 foot / 12 inches) = 13/12 feet. The "inches" units cancel out; this type of procedure can be used with any units based on ratios. So we have a 13/12 foot by 13/12 foot square tile. To get the area of this tile, we just recall that the area of a square is just the square of the length of a side (just multiply the length of any side by itself). That means the area of this tile is (13/12)^2 square feet, or 169/144 square feet. If we perform the division to get decimal notation, we get 1.17361... square feet. Since we only have 2 significant digits in our initial information (the tile company cannot make tiles that are exactly 13 inches on each side, the real length is greater than or less than 13 inches by an unknown amount), we can only have at most 2 significant digits of accurate information in our result. If the original length is very close to exactly 13 inches, then the area should be close to 1.17361... square feet. The closest area with 2 significant digits to that area is 1.2 square feet.
That is 208 square feet. Since the tiles are a square foot each, then in theory, you'd only need 208. But if they are not placed evenly, or you start placing from the center, you might need as many as 28 more (16+13-1). That would be 6 boxes of floor tile, assuming that you get 40 per box. For the thicker industrial grade tile, you'd get less in a box.

About one hundred =========== 13 feet = 13 x 12 inches = 156 inches The area of a room 13 feet x 13 feet = 156 x 156 sq. in. = 24336 sq. in. area of 1 tile = 16 x 16 sq. in. = 256 sq. in. Dividing area of room (in sq. in.) by area of one tile: 24336/256 = 95.06 95 tiles are needed for a room 13' x 13'
12 x 13 or 156 tiles.
A 13 x 13 tile is 1.74 sq ft. 144/1.74 = 123 tiles
Calculating how many tiles in a room· 12"X12" is DUH 144 sq inches & 1 sq foot· so multiply any tile size by its 2 dimensions ie 12"X12" or 16"X16" divide by 144 & that = the sq ft per tile.· 13"X13" is 169 sq inches divided by 144 sq inches in a sq foot =1.174 per tile· 18"X18" is 324 sq inches per tile divided by 144 sq inches per sq ft= 2.25 sq ft per tile· 20"x20" tiles are 2.778 per tile· 24X24 tiles are 4 sq ft per tileFormula would look like this(Tile L"x W"= sq inches)divided by 144 sq inches=sq ft per tile) room area divided by sq ft per tile= how many tilesSoooo once you know the sq feet you need, add a little for waste & breakage & ooops cuts & you will have enough..
You will need 25, 13x13 tiles.

About 137 tiles, if they are 1ft X 1ft dimension, or about 137 square feet of tile. If you are using smaller tile, calculate how many tile are needed per square foot and multiply that times 137.
To determine how many 16 x 16 inch tiles are needed for a 13 x 13 foot room, first convert the room dimensions to inches: 13 feet equals 156 inches. The area of the room is 156 inches x 156 inches, which equals 24,336 square inches. Each 16 x 16 inch tile covers 256 square inches. Dividing the total area of the room by the area of one tile (24,336 / 256) gives approximately 95.25, so you would need 96 tiles to cover the room fully.
How do I figure a room for 16X16 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 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.... · 12"X12" is DUH 144 sq inches & 1 sq foot · so multiply any tile size by its 2 dimensions ie 12X12 or 16X16 & that = the sq ft per tile. · 13"X13" is 169 sq inches divided by 144 sq inches in a sq foot =1.174 per tile · 18"X18" is 324 sq inches per tile divided by 144 sq inches per sq ft= 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.
One tile of size 13' by 13' will cover 169 square feet and so will be more than sufficient.
13x13= 169in(one tile) 300/169= about 1.8 (amount of tiles that can fit)
