jojy,

They seem to have no width restrictions either...

I hate running into sites that seem to have google ads as their principal content. Larger ads would encourage that. On the other hand, In many cases, one large ad would make for a better user experience than multiple smaller ones.

Given the "debate" in this discussion, as ASA acknowledged... it implies that AdSense should supply us with these choices... Some could choose not to use it, but I would really like to see at least 25 size choices to best fit into all kinds of pages (not just the current 12)... Obviously, the display ads would require fewer size formats...

We could have a debate about using 10 ad units on a page, too, but that wouldn't mean Google should allow 10 ad units per page just because some people wanted them.

As AdSense continues to evolve beyond its original role as a CPC text-ad network, advertiser demand is likely to the most critical factor in determining what ad sizes and formats are available to publishers. In other words, if Google thinks it can sell 300 x 600 display ads, the 300 x 600 size will have a pretty good chance of joining the existing ad sizes (although one can only hope that, if 300 x 600 is offered, it will be accompanied by tighter restrictions on the number of ad units per page).
