Hello James,

The width of such Objects is determined by the overall width of the page, divided by the number of Objects in each row.  Or to put it another way, if you wish to increase the width of this Object then you need to either increase the width of the entire page (using the template editing tools) or remove other Objects from the same row (if applicable) and having done so you then expand the Object to occupy a greater share of the row, or put this particular Object on its own row in the page (if acceptable).

You can also increase the width by reducing the width of other Objects in the row.

Hope this helps.

Kind regards,

Paul
