Change Paper Size

Hi

I have to change the paper size of a report. Paper size is half of the A4 sheet paper, this is not mentioned in the PaperSize Propery. Is there any way to change it.

It has to be supported by your default printer for you to be able to select it. Can you select it (without changing printer) from other programs?

Paper size has Erick informed is coming from printer settings. Change to default printer that supports natively that kind of paper and will see it.
