cutting plywood - rec size? Advice and information on tiling and fixing tiles to a variety of surfaces

[Heeber]

Hi folks - this may be a very dumb qn, but here goes....

I am going to be tiling a floor 239cm x 189cm. The flooring is 18mm flooring hardboard t&g sheets.

I've bought 244cmx122cm 6mm hardwood plywood to cover it first. My question was what is recommended for cutting these sheets - is it better to keep the pieces as large as possible - i.e. I could get one full sheet in (slightly trimmed in length) plus another narrowed. But - is it 'better' to trim into a regular size first - say 50 x 100 and 'tile' them?

Thanks,
Heeb

H,

If poss.

One full sheet.

As less joints = less movement = less chance of cracking tiles or grout!!!
