How big should a web banner be?

Websites are designed for a resolution of 1024 x 768px. Below are the standard web banner sizes that you can implement on any website. The ones highlighted in pink are considered the 5 most effective web banner sizes according to Google. Below is a mock-up of the 5 most effective web banner sizes on a web page.

The remaining ads, Large Rectangle (336 x 280), Half Page Banner (300 x 600) and Medium Banner (300 x 250) also have image and text options in Google Adsense and are typically placed in the sidebar widget of a website or embedded on the web page in the main content area. The size of the TEAM header banner is the exact size of the HOME page header banner (1600 px X 1050 px), although it is displayed thinner. While it's great to hear people thinking about how images should be formatted, the answer to this question is often not straightforward. One of the trickiest things about creating websites today is that we have to ensure that the user experience is equally effective on all devices and screen sizes, whether it's a phone that fits in your pocket, a laptop or a much larger retina display.

We need to bear in mind that even if a computer screen is physically the same size as someone else's, their screen resolution may be different, making the same design look very different to them. The 300×250 banner should be part of your banner inventory, as it works very well on both desktop and mobile, and covers a large part of the overall inventory.
