1. Open your theme’s functions.php file and add this code at the end of it:

//* 1600px width for tiled gallery
add_filter( 'tiled_gallery_content_width', 'custom_jetpack_galleries_width', 15 );
function custom_jetpack_galleries_width() {
	return 1600;
}

2. Open your theme’s style.css file and add this code at the end of it:

/* Full width for the home section 3 */
#home-section-3 .wrap {
	max-width: 100%
}

/* Remove left/right padding for width edge-to-edge (optional) */
#home-section-3 .widget-wrap {
	padding: 0;
}

Second part of style.css’s code is optional and I wouldn’t add it as it looks better with some padding on both sides.
