If you mean three documents, you can use the canvas size command, three times with different anchor points for top-centre, middle-centre and bottom-centre. You may wish to be pixel-precise rather than using 33.33% as the canvas size value, which could mean that one of the three tiles is sized a little different to the other two.

There are also various scripts:
