can someone tell me if this is correct.
1. measure from one end of the room to the other to find the centre of the room but measure two points and join together with straight edge.
2. measure from the other way and two points again and then put a square on the first line and then join the other two marks up and then this should give me the centre of the room plus my lines will be square which will mean all layed tiles will be square and then all cuts at edge done as neccessary.


Is the above correct, please help

yes...but in addition loose lay one row of tile length and width of the room...then you'll have an idea of how the cuts will be at the walls..adjust accordingdly to make sure you don't get any small/fiddly cuts.

Thanks Wine~o, so my way to square it up is correct will do on the dry laying thanks

No it isn't

That will give you a parallel line from the edge, but not necessarily square with the walls at the end of each line.

To do that you would need to apply the 2-3-4 rule.

whats the 2-3-4 rule please scruff im starting in the morning

you go along 3unit then loosely at right angles 4 units then its 5 units diagonally makes a square

if you want to make a square you must work accurately if you use 3x1"par[69x22mm] draw a point centrally across the timber where they join these must be exactly 3 4 and 5 where the lines cross so have about 3"/75mm so you have a small overhang each end so the screw is away from the end where the lines cross

you can use any units you like inches feet metres or multiples off for example 15x20x25"

a 3 feet x 4 feet right angle will measure 5 feet across the diagonals

So if you mark 4ft from the wall along the center line, then 3ft along the wall, if it is 5ft from the two ends the wall is square with the line.

scruff i think i got that, but if its not 5ft then what line do i move

use multiples off inches or cms as in multiply the 3 4 and 5 by say 8 so 24x32 and the diagonal 40

the big one [5]is a diagonal between the 3 and 4 outer ends

Big-All
sorry to be a pain, are you able to do a simple sketch and post it on here

Bit like this...

You move the line in or out until it is, to get the perfect square.

You may find centralizing the tile both directions and cutting the edge tiles to fit will be the best plan, as it's very unlikely to be square all round.

Lay a dummy run along the line the full length of the room.
