The champion – with 170,000 square feet – remains MGM Grand (which partly accounts for its nickname, "the Green Monster"). For sheer casino square footage, the 21 in Las Vegas that crack the century mark are:
| MGM Grand | 170,000 | Bellagio | 155,000 | Aria | 150,000 | Mandalay Bay | 135,000 | The Orleans | 135,000 | Texas Station | 132,437 | Caesars Palace | 129,000 | Sam’s Town | 120,000 | Luxor | 120,000 | The Rio | 120,000 | Venetian | 120,000 | Wynn LV | 110,000 | Monte Carlo | 102,220 | Palazzo | 102,000 | Circus Circus | 101,286 | Sunset Station | 101,000 | The Mirage | 100,220 | Aliante Casino | 100,000 | Stratosphere | 100,000 | Riviera | 100,000 | Excalibur | 100,000 |
