How Flat Is Texas (States Compared)

Texas is such a large state. It can be hard to imagine the terrain overall and if it’s flat compared to other states.  

If you live in or plan to visit Texas, you may wonder how flat the state is and how its hilliness compares with other US states. This article will explain the flatness of Texas and answer other hill-related questions you might have!

Quick answer; Texas is mostly flat! Texas is considered one of the flatter states in the US in elevation and feeling. 

Feeling means that people think the appearance and terrain of the state are flat, but topographical maps and geological studies show it’s one of the flattest states. So in both perception and scientific reality, Texas is flat!

Flat Parts of Texas

The flattest parts of Texas run along the coast of the Gulf of Mexico. Generally, you can find the flattest parts of Texas to the east and areas near the ocean. 

The flattest parts of Texas include the Great Plains region, the Coastal Plains, and eastern locations where it’s very swampy. Swamps and bogs require a low elevation, and the eastern side of the state has this kind of terrain which bleeds into neighboring states like Louisiana.

The border between Louisiana and Texas is one of the flattest areas.

Hilly Parts of Texas

The most rugged and hilly parts of Texas lay toward the north and west. Hills trail down from the rocky mountains, the Guadalupe Mountains, and the Pecos River, creating the hilliest terrain in the state. 

This area leads into Big Bend country, where the terrain begins to flatten as it moves toward the coast. Guadalupe Peak is the highest place in Texas, rising 8,749 feet high, over 1.5 miles. 

Other hilly parts of Texas include regions in the Texas Hill Country in Central Texas. Most hills here rise to about 400 or 500 feet, which is not particularly tall. This area consists of the Edwards Plateau, another high point, but the plateau itself is flat. 

The plateau is constantly changing and eroding, reshaping the landscape. Erosion takes millions of years, and the elements’ effects on this plateau have produced rolling hills and flat savannahs on different sides. 

How Much of Texas Is Flat?

If you want a hard number to associate with how flat Texas is, there is a percentage that may satisfy you. 

Texas terrain is roughly 44% flat. Only 6% is super flat, 12% is very flat, and a whopping 26% is generally flat. 

That means 57% of Texas is hilly or “not flat,” but this is still a large flatness percentage compared with most states. Even the flattest states in the US hardly exceed 50% flatness.
