Latin American Pacific Coast vs. US Coastline: Length Comparison

The United States coastline is significantly longer than the Latin American Pacific coast.

• US total coastline (NOAA): ~12,383 miles (19,928 km) – Atlantic, Pacific, Gulf, Arctic, Great Lakes, islands.
• US Pacific coast (lower 48 + Alaska): ~7,600 miles alone (Alaska ~6,640 mi).
• Latin American Pacific coast (Mexico to Chile): ~6,000–7,000 miles (estimates vary by measurement method).

Even the US Pacific coast alone exceeds or roughly equals the entire Latin American Pacific coastline. The US total coastline is roughly double.

Measurement methodology (fractal dimension, scale) affects absolute numbers, but the US advantage is robust across methods.
