If it is a blogger platform then you should go to your dashboard. If it is still the old version then: design > width and you can edit the width of the page and sidebars etc. If it's the new control panel then: design > customise This will take you to the same page. If you are handy with coding then you can always edit the HTML and CSS to suit yourself
Or you can chage the width of your page, its not that much tough , just need to know a bit css. From design->Edit Html then search (ctrl+F) for Body, and see what the current size , reduce the size until you get your actual page size, it's better to see preview fast.
