Large format maps are an indispensable tool in the GIS mapping industry. They offer comprehensive visual renditions of complex geographic areas. But to fully utilise these maps—namely, to organise and analyse the various locations and boundaries of Earth—they must be appropriately sized and fit to scale before being printed.

To resize and print oversized maps, careful scaling techniques must be undertaken. This will ensure that, once printed, the detail in the maps remains of optimal quality and is decipherable by users. In this article, we will uncover the process of scaling oversized maps for print jobs using such techniques. Whether you're a map designer, an architect, or a topographer, understanding the nuances of resizing large format maps is crucial for generating high-quality printouts that effectively communicate geographic information.
