add_image_size set exact width + height does not matter

Hi,
by floating I mean “does not matter on height, but need the exact width”.

The Image is 1070px wide. I put the code to the functions.php and it added options to the dropdown menu automatically. It´s in theme setup.

The whole code looks this way:

if (!function_exists('webreseni_setup')) :
	function webreseni_setup()
	{
	
		load_theme_textdomain('webreseni', get_template_directory() . '/languages');

		add_theme_support('post-thumbnails');

		add_image_size('figure', 241, 140, TRUE);
		add_image_size('recommended', 85, 9999, FALSE);

		add_image_size('fb_thumb', 1200, 630, TRUE);
		add_image_size('4_x_img_nahledy_mobile_app', 155, 9999, FALSE);

		add_image_size('full_widthn', 956, 9999, TRUE);
    add_image_size('full_widthn2', 956, 9999, false);
    add_image_size('full_widthn3', 956, 9999);
    add_image_size('full_widthn4', 956, 100, false);
    add_image_size('full_widthn5', 956);

		add_filter('image_size_names_choose', 'ml_custom_image_choose');

		function ml_custom_image_choose($args)
		{

			global $_wp_additional_image_sizes;

			// make the names human friendly by removing dashes and capitalising
			foreach ($_wp_additional_image_sizes as $key => $value)
			{
				$custom[$key] = ucwords(str_replace('-', ' ', $key));
			}

			return array_merge($args, $custom);
		}

		//	add_filter('jpeg_quality', create_function('', 'return 100;'));
// This theme uses wp_nav_menu() in one location.
		register_nav_menus(array(
				'primary' => __('Primary Menu', 'webreseni'),
		));

// Enable support for Post Formats.
		add_theme_support('post-formats', array('aside', 'image', 'video', 'quote', 'link'));

// Allows theme developers to link a custom stylesheet file to the TinyMCE visual editor.
		function webreseni_add_editor_styles()
		{
			add_editor_style('custom-editor-style.css');
		}

		add_action('init', 'webreseni_add_editor_styles');

// Setup the WordPress core custom background feature.
		add_theme_support('custom-background', apply_filters('webreseni_custom_background_args', array(
				'default-color' => 'f9f9f9',
				'default-image' => '',
		)));

// Enable support for HTML5 markup.
		add_theme_support('html5', array('comment-list', 'search-form', 'comment-form',));
	}

endif; // webreseni_setup
add_action('after_setup_theme', 'webreseni_setup');

Anyway, even if I use the WordPress settings to set the sizes of a thumbnail, it only resizes to 700px wide. It almost looks like there is some width maximum, is it possible?

Hi, thanks for help. I found the problem https://codex.wordpress.org/Content_Width it was set to 700px. In twenty* is set to 525px ($GLOBALS[‘content_width’] = 525;), that´s ridiculous.

In twentyseventeen is the width size 525px, maybe it´s fine for that layout, I don´t know.

“What is rather strange in your case is it appears that the full size image is not available in the image insertion dialog box. ” – No, it´s not removing it, you can see it in dialog in the image above “Původní velikost 1070 x 504”.
