Standard Ad Sizes

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
