LAS VEGAS (KLAS) — Las Vegas is mentioned in lists of things from around the world. But when it comes to the size and height of the hotels – it dominates.

Regarding the world’s largest hotels, the Las Vegas valley is home to five of the top 10, 8 of the top 15, and 25 of the top 50. It isn’t however, home to the largest hotel in the world. That goes to the First World Hotel in Malaysia with 7,351 rooms. This is 259 rooms larger than The Venetian Resort (Venetian and Palazzo Towers).

When looking at the hotels just in the Las Vegas valley it's hard to picture just how many rooms there are available to tourists. The top 10 largest hotels in Las Vegas have 47,186 rooms.

According to the Las Vegas Convention and Visitors Authority (LVCVA), there are 150,487 rooms in total.


The STRAT Tower falls into a category of its own. The tower is not a building that can be lived in. However, it is the tallest structure in Las Vegas since 1996.

It was initially known as the Stratosphere, until 2020. Currently, the STRAT hotel is listed with 2,427 rooms which in Las Vegas doesn't even put it in the top 15 for the number of rooms.

The STRAT tower is the tallest observation tower in the United States and the second-tallest in the Western Hemisphere after the CN Tower in Toronto. It is also the second-tallest free-standing structure in the U.S. west of the Mississippi River.
