Or just want a map that you can cut a small piece (up to a square 10° of longitude) from and have it just work (no skewing or non-proportional scaling required) although non-interactive world maps should use Robinson, Winkel-Tripel or something.

Of course, "a square 10° of latitude", while the same size on the full map, will cover different areas. The side length is approximately:

• 1110 km near the equator (0°)
• 960 km in North/South Africa or Florida (30°)
• 790 km in NYC, Venice or south NZ (45°)
• 558 km in Oslo, Anchorage or northernmost Antarctic islands (60°)
• 289 km in central Greenland, northernmost peninsula of Russia or Canada or southernmost sea (75°)
• at higher latitudes, approx. 𝑥 km when 6𝑥 km from the pole

If you're at the Amundsen-Scott research station, a square 10° of latitude won't do, as it covers just about your bed.
