Remove sidebar and use full width of page

Hello lovely WordPress people,

I am tweaking my website/blog and for the homepage I would like to have no sidebar. I was able to change that but now there still is some space where the sidebar used to be. I know I should do this with a new page template but I am not sure how to change this with my theme specifically.

Page.php

<?php get_header(); ?>

<div id="content">

	<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
    <div class="post" id="post-<?php the_ID(); ?>">
        <small class="caps"> </small>

        <h1><?php the_title(); ?></h1>

        <div class="entry">
			<?php the_content('<p class="serif">Read the rest of this page »</p>'); ?>

            <?php wp_link_pages(array('before' => '<p><strong>Pages:</strong> ', 'after' => '</p>', 'next_or_number' => 'number')); ?>
        </div>
    </div>

    <?php endwhile; endif; ?>

    <?php edit_post_link('Edit this entry.', '<p>', '</p>'); ?>

    <?php comments_template(); ?>

</div>

<?php get_sidebar(); ?>

<?php get_footer(); ?>
