how many 300 mm tiles

[vivaro]

im looking at laying some 300mm tiles on a floor , can you try to help me and calculate how many tiles

room sizes
2.5 mtrs long
2.0 mtrs wide at 1 end
600mm wide at other end

as you can see by sizes room has a angle wall
any help would appreated

[Dave]

i would say need 4.5 mtrs or 50 tiles as there is 11 to the mtr at 300mm

[vivaro]

i tell them to get 5 mtrs , will be a through cuts to do
thanks dave for your help

no probs mate good luck with job and post some pics..........

heres a nice easy calculation for you. In your head convert cms to meters.
So 30 x 30 = 0.3 x 0.3
Which equals 0.09
1/0.09 = 11.11

So there are 11.11 tiles to a meter. Multiply this by the sq meterage of the room and you have the number of tiles you need.

Same with any other tile...
30 x 60 = 0.3 x 0.6
== 0.18
1/0.18 = 5.56
So 5.56 Tiles per meter.

Also, if your room isn't square, then draw it out neatly on paper, and try and square off anything you can and work it out in sections. If its an angled wall, then i draw a rectangle so the wall would run through both corners of the rectangle, then when you work out the area of the rectangle, the area of the bit you want is half of that.

Its really hard to explain but really simple to show someone with a piece of paper and a pen. Hopefully ive made some sense though.

oh, and another thing to add... when im working out tiles, if the tiles are less than33 x 33 then i allow 5% extra for wastage, and if theyre more than 33 x 33 i allow 10%. This normally works out pretty much spot on. If its mosaics, then its much less than 5 %.

Every box of tiles i buy of 300x300 from which ever manufacturer has only 11 tiles in it so 9 tiles at 300 x300 gives you 900 sqaure then two tiles divided into 6 x 100mm and that added to 900 gives you 1 sq mtr..

[Dave-T]

yeah, most people work to 11 tiles to a meter with 300 x 300s. Its not technically exactly right as it is 0.11 of a tile out. Which on most floors isn't worth worrying about. Even a lot of manufacturs work on 11 to a meter now. Doing maths at degree level however made me pretty obsessive about accurate figures, so i allways still do all my working out to 4 decimal places and round to 2 on the last calculation. For the most part just rounding tiles per m2 off to a whole or half number is fine. That calculation is worth remembering though as you dont have to remember the number of tiles for each size, you can just chuck the numbers into a calculator and save the brain for more pressing matters like tea and pies.

i agree dave mate and yes! tea no sugar and sauce on pie please....lol
