Blank world map
World maps to print on US Letter, sideways. The blank map outlines every country for labeling or coloring; the coastline version has no borders at all, for continents and oceans.
The maps use the Equal Earth projection, which keeps every country's area in true proportion: Africa is shown as big as it really is, unlike on the Mercator maps many of us grew up with. Borders are from Natural Earth, a public domain map dataset.
