Why do we need any standards in sizes ,I think it would be so great if we create any size of Ad that we feel like, just in case – a place of 40×40 is available on the right side of the site, we will make up the Ad of the same size and fix it up there, so great we occupied the size perfectly , but No that’s not a right way !! Technically , by business perspective or by any way it won’t be right way to handle things at higher level . When online advertising started there were no standardization of sizes but with time the online industries started to grow and advance a lot there was a need to make standards of everything so that everyone remains on the same page with no confusion.

With standardization of sizes , the advertiser’s didn’t have to design new ads for each site they advertised on , ans also publishers were able to have standard designs for their pages to accommodate specific ad dimensions.The standardization helped both advertiser and publisher , the publisher don’t have to worry for non standards ad sizes that don’t fit the design of their site , just like i gave example for 40×40 ad size. And for advertiser they just have to create one set of ads and know the most sites will be able to accommodate the ad dimension they use.

I am sure you must have got the right reason for standardization so let’s get to know what are the standard sizes we have in online world ::

728 x 90 : Leader-Board

This size is generally seen on top of the site or sometimes at the middle and bottom.

300 x 250 : Medium Rectangle

Well known used size which is generally seen on every site.

160 x 600 : Wide Sky-Scraper
