I see you already have this function defined, so change the functions.php code with this:

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', 'custom2_jetpack_galleries_width', 15 );
function custom2_jetpack_galleries_width() {
	return 1600;
}
