different post sizes in wordpress

I want to display my images in a different size thumbnail in my single.php compared to my home.php.

Here's my code I added in functions.php

add_theme_support( 'post-thumbnails' );
add_image_size('new-thumbnail-size',600,340, true);

Here's my single.php

<?php if( get_the_post_thumbnail() ) : ?>
<div class = 'postImgCon'>
                        <div class="feat-img">
                                <?php the_post_thumbnail('new-thumbnail-size'); ?>
                                <?php endif; ?> 

The image is not cropping or changing at all. Any help would be greatly appreciated.
