Notes on Measurements and Rankings

Measurement Differences: Some casinos report total floor area (all facilities), while others focus solely on gaming space. Wherever possible, gaming area is prioritized in the ranking.
Sizing Estimates: Figures may vary based on expansions or renovations. These numbers reflect widely recognized estimates to date.
Geographic Diversity: The list spans global destinations—from Asia’s Macao to Europe’s Lisbon, and across multiple U.S. gaming hubs.

Why Size Matters

Large-scale casinos like The Venetian Macao and City of Dreams are masterclasses in immersive luxury and scale. Their sheer size enables them to offer expansive gaming floors alongside shopping, entertainment, and accommodation—all under one roof. In contrast, even smaller huge casinos still blend vast gambling options with hospitality and entertainment, underscoring how modern casinos evolve into full-fledged resorts.

This ranking provides a window into the world of grand-scale gaming—destinations that redefine what it means to be “the largest.”
