Billboard sites are individually graded and therefore a standard rate does not apply.

Variables include location, (demographic) if the site has lights, siting, is it at traffic lights or on a highway plus numerous other factors which affect viewing time, eg angle to road etc.

The industry has 3 standard sizes. 06 sheet, 24 sheet and Supersite. The numbers refer to the number of sheets of paper required to cover a board however modern printing presses use larger sheets of paper and now these sites only require half the number but the old name still remains.

The term Supersite was an upgraded 48 sheeter and was originally a trade name used by Australian Posters in the 1980s as a marketing name for slightly larger size board.

Eventually the industry adopted the name and new size and is now the standard for large format advertising.
