How do I make the home page show 10 posts? Currently showing 5 Posts per page.

Hello World,

I went to settings -> reading -> posts per page -> 5.

Now I have 5 posts on every page. How do I make it so that my home page has 10 posts? and every other page remains 5 posts?

Here’s my index.php

<?php get_header(); ?>
<div class="cont">
  <div class="main">
    <?php while ( have_posts() ) : the_post(); ?>
    <?php  if ( !is_paged() && ( $wp_query->current_post <= 2 ) ) : ?>
    <?php  if ( $wp_query->current_post == 0 ) : ?>
    <a href="<?php home_url(); ?>">
    </a>
    <div class="three_container">
    <?php endif; ?>
      <div class="newest" <?php post_class() ?>>
          <a href="<?php the_permalink() ?>">
            <?php the_post_thumbnail( array(280,280) ); ?>
          </a>
          <h2>
            <a href="<?php the_permalink() ?>">
              <?php the_title(); ?>
            </a>
          </h2>
          <?php the_excerpt(); ?>
      </div>
    <?php  if ( $wp_query->current_post == 2  ) : ?>
    </div>
    <div class="sidebar-container">
      <div class="posts-container">
      <?php endif; ?>
      <?php else : ?>

      <div class="blog-posts" <?php post_class() ?>>
          <a href="<?php the_permalink() ?>">
            <?php the_post_thumbnail( array(180,180) ); ?>
          </a>
          <h2>
            <a href="<?php the_permalink() ?>">
              <?php the_title(); ?>
            </a>
          </h2>
          <?php the_excerpt(); ?>
          <div class="entry-date">
            <p><?php echo get_the_date(); ?></p>
          </div>
      </div>
      <?php endif; ?>
      <?php endwhile; ?>
      </div>
    </div>
      <?php get_sidebar(); ?>
      <div class="old">
        <?php echo get_next_posts_link('Older Posts ?'); ?>
      </div>
    <?php get_footer(); ?>
  </div>
</div>
