Colorado is certainly one of the bigger states in the US. Of course, you can answer the question of how big is Colorado by talking about the landmass. If you rank US states by their landmass, Colorado ranks eighth out of all 50 US states. If you have visited Colorado, then you probably figured that it was a large state.
That is certainly true. The total area of the state of Colorado is 104,095 square miles. One other thing to note is that this area consists mostly of land. Colorado only has 376 square miles of water. This means that its water accounts for less than one percent of the state's total area.
Colorado Is Not An Extremely Populous State
In contrast to its ranking by landmass, Colorado doesn't rank all that high if you measure the state's size by population. According to the 2020 US Census, the state of Colorado had an estimated population of 5,812,069 people on July 1, 2021. Colorado only ranks 21st in terms of its total population out of all 50 US states. It is also worth noting that Colorado's population only grew by roughly 700,000 people between April 1, 2010, and April 1, 2020.
