How to enlarge margins in excel

Question

I am attempting to enlarge my page from a-p in width. How do I enlarge my margins?

Answer 1

do you mean widen the columns a thru p?

if that's the case, take your mouse and left click column A and drag it over to column P.  You will see the contents of those columns being highlighted as you do it.  Then put your mouse in between one of the columns (for example inbetween  A and B columns). You'll notice our mouse curson change to a different symbol.  Click and then drag the columns; as you do you'll see the columns widen.  

You can also do this one column at a time (same technique...just put your mouse inbetween the column, click and drag it wider or smaller).

Same techique works on the row height too.
