Help!: Tile calculator

[mart08]

Hi guys, just banging my head as can't find a decent tile calculator on the web! Every time i go to use mine the tile sizes i want aren't listed!! Thought I'd ask on here as It'll be quicker. Thanks in advance.

Tile conversion chart from CTD..

All coverage figures are for guidance only and are rounded to the nearest tile, except in the case of very large sizes. With floor tiles, allowance has been made for the grout joint in calculating the coverage. Please note that not all the sizes are shown on this chart.

Thanks Dave.

No probs...

If your tile size isn't shown here to get the M squared coverage for your tile you simply apply the following:

For square tiles:

Divide 1000mm by the dimension of your tile.

Square the answer (multiply it by itself).

That will give you the figure.

For example for 500mm x 500mm tiles you divide 1000 by 500 and get 2

Multiply 2 by itself, that gives you 4

For oblong tiles:

Divide 1000mm by the length

Divide 1000mm by the width

Multiply the two answers - that's the figure you need.

If you want the results in square yards then work in imperial.

One inch is 25.4mm. If you're really fussy, measure the tiles.

Then using the approach above, instead of dividing 1000mm by the mm dimensions of the tiles, you divide 36 inches by the inch dimension of the tiles.

I've never taken grout lines into account, but if you really wanted to I guess you could add the thickness of the grout line to each dimension of the tile before you work this out.

One rider with both this method and the table that Dave has provided:

ADD 10% to the order for wastage, cuts and mistakes etc. If the job is likely to produce a lot of waste because of the way they are to be laid then you may need to add more. This may be affected by a pattern.

Sometimes I have been known to 'count' the tiles on each surface, imagining them fixed in place. To do this I measure each surface and then count fixed increments in both directions, taking into account the cuts on the edges, and knowing that I have to leave good edges on cut tiles abutting other tiles.

......or you could just use that one

Not to step on any toes but

Height of tiles (cm) by Width of tiles (cm) = X
10000 divided by X = tiles per m2

for example
25x40 = 1000(x)
10000 divided by 1000(x) = 10.... 10 tiles per m2

to show it works on complicated ones

10.8x25.5 = 275.4
10000 divided by 275.4 = 36.31082 tiles per m2



This is for when you forget to bring your computer with you to price up a job

[Dave-T]

I do the same as you DETileD, only i do it in metres, find it a bit easier. For example a 150 x 150 tile...

0.15 x 0.15 = 0.0225
1/0.0225 = 44.4444

Down to what everyone finds easiest really, but thats the method thats picked up quickest by my staff. Whatever way you do it though, it becomes second nature quickly.

Grout quantity calculations tho, theres a different matter. lol. I've spent hours trying to teach people that one.

[Mark B]

I agree with Dave-T.

As we all seem to measure walls and floors in m2 I find it easier to measure the tiles in m2 too.

But as Cornish Crofter says, you still need to allow for cuts and layouts that will require more tiles.

[DEtileD]

I agree.
Formula's all the same. Can look up tiles in km if you wanted 0.00015x0.00015 etc

Where I teach the CM method (in stores) it is probably easier for the staff to understand (less fractions) , for the average tiler M2 is probably easier (less zeros).

[Dave]

We fixers measure up in sqr mtrs.......leave it down to the store to work out quantities....not all customers know what they are going to buy..( size wise) so sqr mtrs is easier to price....

[mickbull]

This is the easy way guy's and gal's:-

Say you are using 150x150 tiles, and you need to know how many in a square metre...

The magic number is 1

So the sum is: 1 divided by .150 divided by .150 = 44.44 tiles per m2

So if it was a 600x400 tile it would be...

1 divided by .600 divided by .400 = 4.16 tiles per m2

This can work either way, so could be 1 divided by .400 divided by .600 would bring out the same result!!

Easy!!

[bigandy]

I find this is the easiest



look on the pack or on the label in the shop

I had an hour to spare, and I was bored, so I sat down and did a tile amount calculator (number of tiles, m2s, margins, etc etc). While at it, I included a planing aide (for educational purposes), which suggests how you plan a generic surface given the details you enter into the calculator.

I can't guarantee that it's error free, cuz I couldn't be arsed to check twice

Making it kept me amused for an hour or so, but now I'm bored again

Cheers.

and dont forget to add at least 7.5% waste

[peterhouse]

iwant to be a tiler utill iread all this,,,,,,,,,lol allready got headace as my maths are not tha good,plus i ome from the generation that works in feet and inches

Hello there

I had 20 minutes to spare so i had a play with swe's tile calculator, great calc by the way swe.

The tile calculator will now give a price for the tiles and an idea of grout needed. Plus a couple of other bits to give a total price for the project.

The wife was happy to see just how much it was going to cost me to tile the utility!

Attachment is removed coz you is a new member and need to post more first. OK.
