Billboards are an excellent way to advertise to the masses, as it can be seen in residential areas, public transports, work and social events.
Billboards have been used since the early 19th century, following the invention of lithographic printing, that allowed cheap printing of large sheets. The earliest billboards were mostly to be found on the sides of buildings before being used on the roadside following the availability of cheaper automobiles.
Billboards come in many sizes which some are common than others. Sizes vary depending on the country as listed in Designs.ai’s document size guide.
