What is the formula for working out how many tiles I need to buy please?
Question:
Answers:
Area to tile ie 10m2
Divided by tile area ie 300mmx300mm = 0.09m2
10 divided by .09= 111.11 so 112 + waste
NOT ROOF TILES
It depends on how the size of the tiles you are using. Work out the area you want to tile - multiply the length by the width. If necessary, if its a complicated area, split it into rectangles and calculate the area of each before adding them together. Then work out the area or each tile - 15 cm square is 0.0225 squ metres. Divide the total area by the area of one tile and that will give you the number of tiles. Don't forget to add at least 10% for cutting and wastage.
that depends upon what size tiles and the square area of the work space ?=
divide that by the size of tile USE THE SAME UNITS.. If you measure in inches use inches for the tile.. If you use feet, use feet for the tile.. Assume about 5% waste or less if you don't mess up much...
Example
room is 10ft by 10ft =100 square feet.
using 12" tile (1ft by 1 ft) that is 100 tiles plus waste so 5 extra tiles.. The grout will take up some space so you have to allow for a little play.. but job set up is a different question all together..
If you are using 4" tiles then you need 9 of those per sq ft. (4x3=12=1 linear foot, then do the same for the width cause it's a square that give 3 rows of 3 or 9 tiles) so 900 4"tiles plus the waste of 45 tiles.. In this case it is hard to mess up tiles on the middle of the job so you may need less waste but if you can take them back.. go ahead and get them.
6" tiles is 4 tiles per sq ft for 400 tiles..
I think that will answer that... If you are working in metric then make the appropriate conversions and all still applies
Measure the height to which you want to tile, then divide this by the height of the tile you will be using.
Next measure the length of each wall and divide this by the width of the tile.
Multiply these two answers together and you have the number of tiles you require.
You must allow for having to cut some tiles and for breakages.
Buy the heaviest tile cutter you can afford.
Another tip: Do not use a combined tile adhesive and grout. It is inferior to using a tile adhesive to stick up the tiles and a waterproof grout to fill in between the tiles to finish them off.
Do not rush a job like this.
Work out the square metreage of the walls, say for example it comes to 6.5m2.
If you have a 200mm x 200mm tile, thats .2 x .2 = 0.04 m2.
Divide 6.5 by 0.04 = 162 + 10% for cuts = 162 + 16 = 178 tiles.
You have to convert the 200mm into metres which is .2m because the walls are in square metres (work with like for like units).
I always add 10% for cuts/wastage etc..
178 x .04 = 7.12m2. So if a box states that it has 1.2m2 tiles in the box then get 6 boxes which will give you 7.2 m2.
If it is for a wall measure each wall individually in feet or meters. By length x width/height. If you require a border measure separately the length all around the room. Note it down on a bit of paper. If it is a floor then measure again the length by depth and work out if you are to tile underneath any thing and allow for that in your measurements. Then take the measurements to the tile shop and let them do the maths it should be what they are paid to do. It is easier this way than explaining the formula in text on the maths to it all.
The way I do it is, measure one section of wall at a time, measure hight and width, then divide the width first by the size of the tiles ie wall is ten foot wide, tiles r 6 inches change 10 ft into inches and then divide as mentioned, 10 ft using 6 inch tiles is 20 tiles wide , lets say its same hight so another 20 so multiply 20 by 20 =400 tiles always buy more than u need as u cn take them back if u have any unopened boxes for refund. dont forget, get same batch number cos they can be slightly different.
First you need to figure out your square footage.(L*W)Then you need to figure out what size tiles you want to use. Keep in mind the spacing between the tiles. Depending on the size of the tile and the size of the space you should be able to figure how many tile you should need.
use a tape measure dumbo
use a tape measure... lol... lmao ... anyway once you measure your area multiply the width times the length and you have your area. the number of tiles you need will depend on the size of the tiles themselves. then add 10% extra to allow for cutting edges and screw ups. good luck, its all yours now!
1m2 (if you work it out with 10cm2 tiles) is 100 tiles,thats all you need to know.
Figure the square footage(lenght multiplied width) Depending on the room, count on 10 to 20% extra. Bathrooms usually are 20% because of all the cutting. Large square kitchens are less.
Measure lenght
Measure hieght
LxH =area
