let me help you , i had problem that was sort of hard to really solve let me first tell you what i had : i use elegant theme, so the full page is always easy to create ,but i wanted the full width post too but i figured out out to get it to the full width post but the secondary problem was that post should always have comment box but full width didnt have it because the full width page in the epanel setting was disable but when i enabled it all the pages and post had comment box , i mean even my about, contact us etc had a comment box so it was like im stuck but then i finally found these steps and it workded so fine :

1. Install and activate plugin.
2. Copy the single.php file in your theme folder and rename it to: single-fullwidth.php
3. Insert: “Template Name: Fullwidth Post” into the comments area so it would look something like this:

<?php
/*
Template Name Posts: Full Width
*/
?>

And remove the <?php get_sidebar(); ?> bit.
which is normaly at the bottom of the lines inside the file single.php

now save the file with the name : single-fullwidth.php and then upload it in you site for me with the fact i use an elegant theme so i had to place the file in the same forlder : wp-content/themes/mytheme

“mytheme” is the name of your theme so just place the file in that folder where there is your index.php save it and now go to your wp dashboard you will find a “full width ” in your drop down : post template area , good luck for any further help just let me know
