Which regions are best suited for conic map projections?

Conic map projections are best suited for mapping regions that have a significant east-west extent, particularly those located in the mid-latitudes.1

Because these projections are derived by placing a cone over the Earth—tangent to a specific parallel or intersecting at two standard parallels—they are highly effective at minimizing distortion along those chosen lines of latitude. By selecting standard parallels that correspond to the region being mapped, cartographers can maintain greater accuracy for areas that stretch across these mid-latitude zones.213

While they are excellent for mid-latitude regions, they are generally less suitable for mapping the entire globe or equatorial regions, where other projection types, such as cylindrical projections, are often preferred.41
