Search two places above to see how their true sizes compare
Two places, overlaid on one map at an identical real-world scale — so you can see exactly how their true sizes compare, corrected for the way standard map projections distort size by latitude.
Search two places
Type a city, region, or country into each box. Once both are set, the maps align automatically at true scale.
Random city
Click the dice next to either box to jump to a random city instead of typing.
Overlay opacity
Fade the top map in and out to see how it lines up with the map underneath.
Lock / unlock maps
Locked, both maps pan and zoom together. Unlock to nudge one map independently for finer alignment — pick which one with the A / B toggle.
Reset alignment
Snap both maps back to their automatically computed true-scale alignment.
Measure distances
Click Measure, then click two points on the map for a line and the real-world distance between them. Keep clicking to add more; Clear removes them all.
Zoom
Scroll, pinch, or use the +/- buttons. Zoom always applies to both maps together, so the scale comparison never breaks.
Collapse controls
Use the arrow in the top-right to hide the whole toolbar, or the small arrow above "Locations" to collapse just the search fields and free up map space.
