With dimensions of 600mm x 900mm, the Colombier affiche format matches the identical size of the iconic French B2 paper dimension - giving it a surface area of 540,000 sq mm or 0.54 sq meters. Translating to "poster Colombier", its name denotes the format's specific suitability for eye-catching posters, lobby signs, advertising placards, campaign boards, striking leaflets and attention-grabbing print proclamations. This is thanks to its B2 proportions being both impressively sizable yet still practical for mass public circulation. Although international ISO sizes now prevail across printing applications, Colombier affiche remains popular as the classic go-to French format for effective promotional visuals that must be seen from a distance. So whether election hoardings, real estate pitches or neighbourhood announcements, Colombier affiche conveys large notices with true French transmission heritage. Contemporary businesses, marketers, agents and campaign managers value upholding the format for awareness and recall - knowing bold Colombier affiche messaging cuts through today's visual noise much as it commanded engagement across French public spaces and forums of the past.
