Hi there,

We have reduce the width size on single page as of user point of view to read the content.
You can add below line of code in Appearance > Customize > Additional CSS to make the content area to full width.

@media (min-width: 1400px) {
	.post-template-default .site-content .container, 
	.page-template-default:not(.woocommerce) .site-content .container {
		max-width: 1340px;
	}
}
@media (min-width: 1600px) {
	.post-template-default .site-content .container, 
	.page-template-default:not(.woocommerce) .site-content .container {
		max-width: 1540px;
	}
}
@media (min-width: 1800px) {
	.post-template-default .site-content .container, 
	.page-template-default:not(.woocommerce) .site-content .container {
		max-width: 1740px;
	}
}

Thank you for using our theme.
