There should be an internationally agreed standard for the size of both lasagne dishes and sheets of lasagne.
@robpumphrey you've heard of ISOgne I take it

@robpumphrey 100% agree.

ISO standards for bakeware is something we've slept on for too long.

@robpumphrey it should be A series paper. A4 is a family lasagne. A6 is a one person ready meal.
@robpumphrey it's the rounded corners on the dish that get me every time. Apart from that the dish is 3 sheets wide and feeds 6 ordinary people or 4 hungry ones.
@lornajane
Same problem with corners, and I can't resist eating the bits I snap off.
