ResPick will help you check your website responsive design with popular screen resolutions and sizes. This is one of my favorite tool when design themes and templates.
Just input your blog / website URL and click CHECK NOW button. In checker window, click a screen resolution / size that you want to check. You can click on selected screen again to rotate screen.
If you want to share the test with your friends or customers, click Share button when you are in checker window, and copy the share URL then share it direct with them.
Welcome all your suggestions. Thanks.
