Dear Mauricio,

Two ways to accomplish it, an easy an a mor difficult one.

The easy way, make a new layout for the extra size.

The difficult way, change the FRX file for every object on the page.
Remember all sizes in the frx are in 1/10.000 of an inch.
But i dont think it is usefull if just 1 page layout extra is needed.
This system i use for printing bank cheques, as all banks issue cheques with different layout.
