The web is getting fatter, as much as 25 percent fatter in the last year alone.
That’s right, based on the top 1,000 most visited sites on the web, the average page download size has jumped 25 percent since this time last year — 626 kB per page to 784 kB. That’s a hefty weight gain in just a year and of course usually the larger the page, the slower the page.
The latest page size data comes from the HTTP Archive, which keeps monthly tabs on the size of web pages.
As you might expect, the largest single type of content on the average page is still images, which account for 451kB of the total 784kB. Images alone do not, however, account for the rapid increase in page size.
