With ample dimensions of 630mm x 900mm, the Colombier commercial format has a surface area of 567,000 sq mm or 0.567 sq meters. As its name suggests, Colombier commercial was specifically designed for all varieties of business communications like invoices, contracts, inventories, accounts, files, reports and financial statements. The size was used ubiquitously by French industrial and commercial enterprises before ISO standardization. Today Colombier commercial's big, flat, expansive proportions still lend businesses a traditional professional appearance when printed with letterheads, orders, plans, schematics and important records. Although infrequently mass produced now beyond specialty runs, the format remains popular with firms wanting to convey heritage, expertise and distinction by upholding old French commerce customs on paper. Accountants, law offices, wineries and property companies in particular value the sophistication Columbier commercial sheets impart through their visual reminder of history’s great mercantile houses and notable trading guilds that launched global enterprises. The size itself retains commercial gravitas.
