Why do countries look different sizes on traditional maps?
Traditional world maps often use the Mercator projection, which distorts the size of landmasses, making countries near the poles appear much larger than they actually are. SizeOnMap.com uses equal-area projections to show true relative sizes.
Can I compare more than two territories at once?
Yes! You can add as many territories as you want to the map. Each territory can be moved, rotated, and customized independently.
How accurate are the size comparisons?
Our geographic data comes from reliable sources and uses proper equal-area projections. However, all map projections involve some distortion, and geographic boundaries may change over time.
