The 10 Biggest Casinos in Las Vegas

Wynn Las Vegas is the biggest casino in Las Vegas by reported gaming space, with 196,232 square feet (18,231 square metres) in Nevada’s fiscal-year 2025 property report. The Venetian ranks second at 166,194 square feet (15,440 square metres). MGM Grand, Bellagio, Aria, and Mandalay Bay follow, each with more than 150,000 square feet (13,935 square metres) assigned to gaming activities.

This ranking uses one consistent source and measurement: total square footage reported to the Nevada Gaming Control Board for pit games, slots, keno, bingo, race and sports, and poker or pan. It does not mix gaming floor with hotel rooms, convention space, shopping, pools, or the total resort footprint.

2. The Venetian Resort Las Vegas - 166,194 sq ft (15,440 m²)

The Venetian reports 51,084 sq ft (4,746 m²) of pit games, 105,141 sq ft (9,768 m²) of slots, and 9,969 sq ft (926 m²) of poker and pan. The workbook lists no square footage in its main row for keno, bingo, or race and sports.

3. MGM Grand - 156,524 sq ft (14,542 m²)

MGM Grand’s reported total consists of 29,240 sq ft (2,716 m²) for pit games, 115,479 sq ft (10,728 m²) for slots, 6,005 sq ft (558 m²) for race and sports, and 5,800 sq ft (539 m²) for poker and pan. Its slot allocation is the third-largest among these ten properties, behind Santa Fe Station and Mandalay Bay.

4. Bellagio - 156,000 sq ft (14,493 m²)

Bellagio sits only 524 sq ft (49 m²) behind MGM Grand in the official totals. It reports 38,332 sq ft (3,561 m²) of pit games, 103,698 sq ft (9,634 m²) of slots, 6,320 sq ft (587 m²) of race and sports, and 7,650 sq ft (711 m²) of poker and pan.

5. Aria Resort & Casino - 152,644 sq ft (14,181 m²)

6. Mandalay Bay - 151,910 sq ft (14,113 m²)

Mandalay Bay reports 15,763 sq ft (1,464 m²) for pit games and 123,695 sq ft (11,492 m²) for slots, plus 10,454 sq ft (971 m²) for race and sports and 1,998 sq ft (186 m²) for poker and pan. Slots account for more than four-fifths of the reported gaming total.

7. Santa Fe Station - 151,001 sq ft (14,028 m²)

Santa Fe Station is the highest-ranked locals-oriented property in this list. Its 130,000 sq ft (12,077 m²) of reported slot space is the largest slot allocation among the ten, supplemented by 5,376 sq ft (499 m²) of pit games, 4,000 sq ft (372 m²) of keno, 8,400 sq ft (780 m²) of bingo, 1,005 sq ft (93 m²) of race and sports, and 2,220 sq ft (206 m²) of poker.

8. South Point - 146,002 sq ft (13,564 m²)

South Point reports 110,842 sq ft (10,298 m²) of slots, 13,057 sq ft (1,213 m²) of bingo, 8,677 sq ft (806 m²) of race and sports, 8,580 sq ft (797 m²) of pit games, and 4,846 sq ft (450 m²) of poker and pan. Its mix illustrates why “casino size” is broader than a count of slot cabinets.

9. The Orleans - 135,800 sq ft (12,616 m²)

The Orleans reports 111,240 sq ft (10,335 m²) of slots, 11,400 sq ft (1,059 m²) of pit games, 5,960 sq ft (554 m²) of poker and pan, 4,750 sq ft (441 m²) of race and sports, and 2,450 sq ft (228 m²) of keno. It ranks above several better-known Strip resorts when the comparison is limited to regulated gaming space.

10. Red Rock Casino Resort Spa - 126,987 sq ft (11,797 m²)

Red Rock reports 73,314 sq ft (6,811 m²) of slots, 18,967 sq ft (1,762 m²) of bingo, 15,563 sq ft (1,446 m²) of pit games, 13,259 sq ft (1,232 m²) of race and sports, 4,450 sq ft (413 m²) of poker and pan, and 1,434 sq ft (133 m²) of keno.

Methodology and boundaries

The source workbook contains every Nevada nonrestricted location, so geography has to be defined before sorting. This list includes properties with Las Vegas postal addresses and excludes properties identified with other cities or distant Clark County markets. Green Valley Ranch and Sunset Station would rank near the top on square footage, but both are in Henderson and are excluded from a list titled “in Las Vegas.” Laughlin and Mesquite properties are also excluded.

We use the total in each property’s main row. The state workbook can include a separately named race-book or sports-pool row for some properties. Adding those satellite rows for selected casinos but not others would create an inconsistent ranking, so no separate row is merged into the published total.

The figures are financial-statement square footage, not a tape-measure survey made on the publication date. Renovations, reconfigurations, openings, and closures can change the active floor after the fiscal-year report.

Why other “biggest casino” lists differ

• They use older property fact sheets. A resort may still quote a rounded historical floor size.
• They combine the whole resort. Hotel, convention, retail, and entertainment areas can dwarf the casino.
• They treat the Las Vegas Valley as the city. This can add Henderson properties or exclude downtown.
• They compare slot floor only. Pit, poker, bingo, keno, and sportsbook areas then disappear.
• They use rounded marketing figures. “About 150,000 square feet” cannot resolve a close ranking.

The state-reported total is the most reproducible measure available for a cross-property comparison. It may not match the number a resort uses to describe its public casino floor, because the two sources can define allocated space differently.

Biggest does not mean best

Gaming space says nothing by itself about table limits, paytables, accessibility, crowd levels, smoke policy, restaurant quality, or whether a particular game is operating. A smaller casino can offer a better fit for a player’s preferred game and budget.

Use this ranking to compare physical gaming allocation, not quality or value. Before visiting, check the casino’s current game information and contact the property if one specific table, poker room, bingo session, or accessibility feature matters.
