If you don’t have the option of a full width Page template in your theme, it’s easy enough to create your own. You’ll need to be able to access your theme’s folder on your server, and so if you can do that, this should be a fairly easy process.
We’ll go through it in five steps.
Step 1: Create a New Template File
On your server, find your theme’s folder (wp-content/themes/your-theme).
Create a new file and name it something unique and appropriate (e.g. full-width-page.php). Remember to end it with the .php extension.
After that, find the file named page.php. Open that, copy the contents, and then go back to the file you just created (full-width-page.php), and paste those contents into your new file.
Now, at the VERY TOP of your new file (i.e. BEFORE the content you just added into it), put the following:
<?php /* Template Name: Full Width */ ?>
It should look something like this:

Step 2: Remove the Sidebar
Next you’ll want to remove the sidebar. Search for the following code and take it out.
<?php get_sidebar() ?>
Step 3: Replace the Div ID
Next, you’ll need to find the Div ID for the content and change it, so we can style it the way we like.
More than likely, the div ID for the content will look like this:
<div id="content">
Change the name “content” to something unique and identifiable like “content-fullwidth.”
<div id="content-fullwidth">
Save the file, and you’re done with the template file.

Step 4: Style Your New Template File
Now you’ll need to widen the content area to give you more space.
Go to your style sheet in your admin area (Appearance > Editor > Stylesheet – style.css) and search for the section that controls the content area of your blog.
Typically your content area in your style sheet is named “#content” (easily enough).
Copy this section and then paste it into the style sheet again, renaming #content to the same name you gave your Div ID in Step 3 above (#content-fullwidth).
Then change the width to something wider.
Save your file, and that’s it for the style sheet.
Step 5: Choose Full Width
When you write a Page now, you should see an option on the right hand side for the “Full Width” template that you created.
