Website Page Size Checker is one of the many SEO tools that Mrephrase has developed over these years. This wonderful tool, as the name suggests, is a page size checker that can be used to know the page size of any specific URL. It is a magic tool that users can use to check website size online. If your website takes longer than usual to load then perhaps you need to work on the size of your website because it can result in a high bounce rate as the internet users don't tend to have the patience to wait for the web page to open. An average small web page size is estimated to be 12 KB and that will load very quickly. The more media on a page, the bigger the page size and the slower it will load. Embedded videos, images, audio, graphics, flash, and other forms of media will increase your page size. First things first, it's important for the health and performance of your website that you know the size of your website but how to know the total size of a website? That's where a website page size checker or page size inspector comes into play.
