By Marko Visic·Published 15 May 2026·Sources: CIA World Factbook, US EIA·CC-BY 4.0

Saudi Arabia covers 830,000 sq mi (2.15 million km²) — the 12th-largest country in the world. Texas covers 268,596 sq mi (695,662 km²) — the second-largest US state. Saudi Arabia is 3.09× larger — about three Texases fit inside. But Texas flips the script economically: Texas's nominal GDP is roughly 2.4× Saudi Arabia's (Texas is roughly 2.4× bigger by economy despite being one-third the area).

The oil-giant matchup: Saudi outpumps, Texas out-earns

Saudi Arabia and Texas are the world's two largest oil-producing regions. Saudi pumps roughly 10.5 million barrels per day (state-owned Aramco, plus minor private); Texas pumps ~5.4 million bbl/day (mostly private operators in the Permian Basin and Eagle Ford). Saudi production is 1.94× Texas's.

But the economic outcome inverts: Texas's nominal GDP is roughly 2.4× Saudi Arabia's. Reasons: Texas's economy is diversified far beyond oil (tech in Austin, healthcare in Dallas, aerospace in Houston, finance throughout, agriculture across the Panhandle). Saudi's economy remains heavily oil-dependent — petroleum and petrochemicals make up about 45% of GDP. Vision 2030, Saudi's diversification plan, aims to shift the economy toward tourism, manufacturing, and renewables.

Both regions are mostly desert

Saudi Arabia is roughly 95% uninhabited desert. The southeast quadrant is the Rub' al Khali (Empty Quarter) — the world's largest contiguous sand desert at ~250,000 sq mi. No permanent settlements, sand dunes hundreds of feet tall, temperatures regularly exceeding 130°F. The population clusters in three zones: the western Hejaz (Mecca, Medina, Jeddah), the central Najd (Riyadh), and the eastern oil region (Dammam, Dhahran, Khobar).

Texas has substantial desert too: the Chihuahuan Desert covers western Texas (Big Bend, El Paso, Marfa). The Llano Estacado plateau covers the Panhandle. But Texas also has Gulf Coast humid subtropical climate, East Texas pine forests, and the Hill Country oak savannas — much more variety. About 84% of Texas is rural in terms of land use, but population is concentrated in the Texas Triangle (Houston-Dallas-San Antonio-Austin).

Why this comparison matters

Saudi Arabia and Texas are the only two oil regions on Earth that pump more than five million barrels a day, and people search the comparison because it is the closest real-world test of “what if a US state went up against the country whose energy policy moves the world.” The result reshapes how readers picture both. Saudi Arabia, often imagined as a small Gulf state on a world map, is actually 12th-largest country on Earth and roughly the size of Mexico. Texas, often imagined as the country-sized state, fits inside Saudi Arabia three times.

The comparison also illuminates how geography shapes geopolitics. Saudi Arabia's land area gives OPEC its anchor producer; Texas's shale basins explain why the United States overtook Saudi Arabia as the world's #1 crude producer in 2018 and now sets the marginal global price.

Geography and climate

Saudi Arabia covers the bulk of the Arabian Peninsula and ranges from sea level on the Persian Gulf to 9,843 ft at Jabal Sawda in the Asir Mountains. The interior is the Najd Plateau (2,000–5,000 ft); the southeast is the Rub' al Khali (Empty Quarter), the world's largest contiguous sand desert at roughly 250,000 sq mi. Climate is hyper-arid: Riyadh averages less than 4 inches of rain a year and summer highs of 110°F (43°C); the Empty Quarter regularly exceeds 130°F (54°C).

Texas spans four ecoregions: Gulf Coastal Plains (humid subtropical), Interior Lowlands (rolling prairie), Great Plains (the Llano Estacado plateau and Panhandle), and the Basin and Range / Chihuahuan Desert in the Trans-Pecos. Elevation runs from sea level on Padre Island to 8,751 ft at Guadalupe Peak. Annual rainfall ranges from 8 inches in El Paso to 56 inches in Beaumont. Texas has roughly 1,000 tornadoes a year on average; Saudi Arabia, none. Both share comparable summer heat in their deserts but Texas's humidity east of the I-35 corridor changes the experience entirely.

Population and density

Saudi Arabia's 36.4 million residents (General Authority for Statistics, 2024 census) cluster in three zones: the Hejaz (Mecca, Medina, Jeddah) on the Red Sea, the Najd (Riyadh) in the center, and the Eastern Province (Dammam, Dhahran, Khobar) on the Persian Gulf. Roughly 84% of Saudis live in urban areas; foreign workers make up about 38% of the population. The Empty Quarter and most of the northern desert hold under 1 person per square mile.

Texas's 30.5 million residents (US Census Bureau, 2024 vintage estimate) concentrate in the Texas Triangle — Houston (7.5M metro), Dallas–Fort Worth (8.1M), San Antonio (2.7M), and Austin (2.5M) — which together hold about 70% of the state population on roughly 20% of the land. Texas grew by 470,708 residents in 2023 alone, the largest absolute population gain of any US state. About 84% of Texans live in metropolitan areas; the Panhandle and Trans-Pecos have densities below 10/sq mi.

The economy and what people do

Saudi Arabia's $1.07 trillion economy (IMF, 2024) is concentrated in the Eastern Province, an area roughly 1.5 times the size of Texas's Permian Basin, where Aramco operates the world's largest oil and gas complex at Ghawar. Petroleum and petrochemicals account for about 45% of GDP and roughly 70% of fiscal revenue. Vision 2030 is shifting investment toward tourism (NEOM, Diriyah), mining, and renewables. Currency: Saudi riyal (pegged at 3.75 SAR per USD since 1986).

Texas's $2.6 trillion economy (US BEA, 2024) is more diversified: energy (Permian Basin, Eagle Ford, Gulf refining), tech (Austin, Dallas), aerospace (Houston, Fort Worth), agriculture, healthcare, and finance. Houston is the world's energy-trading capital; Austin hosts Tesla, Samsung Austin Semiconductor, and a growing chip-manufacturing cluster. Currency: US dollar.

10 surprising facts about Saudi Arabia vs Texas

Frequently asked questions

Yes. Saudi Arabia covers approximately 830,000 sq mi (2,149,690 km²); Texas covers 268,596 sq mi (695,662 km²). Saudi Arabia is 3.09 times larger by total area. Three Texases plus a small partial fit inside Saudi Arabia.
Saudi Arabia is 3.09× larger than Texas — about 561,000 sq mi more land. That difference is larger than Alaska + South Carolina combined, or roughly the size of Iran.
Saudi Arabia produces more crude oil — about 10.5 million barrels/day (2024 avg). Texas produces ~5.4 million barrels/day. Saudi outproduces Texas by 1.94×. However, Texas's oil production alone exceeds every OPEC country except Saudi Arabia, and Texas is the #1 oil-producing US state by a wide margin.
Texas — roughly 2.4× Saudi Arabia by nominal GDP despite being one-third the area. Both rank among the world's top-twenty largest economies (with Texas counted as a country). Texas's diversified economy (energy + tech + finance + agriculture) outperforms Saudi's oil-dominated economy.
Saudi Arabia has approximately 36.4 million people; Texas has 30.5 million. Saudi has 1.19× Texas's population on 3.09× the land — making Saudi Arabia much less densely populated overall (44/sq mi vs Texas's 117/sq mi). Most of Saudi's interior is the Rub' al Khali (Empty Quarter), one of Earth's largest sand deserts.
Both have substantial desert terrain. Saudi Arabia is mostly arid Arabian Plateau plus the Rub' al Khali (the world's largest contiguous sand desert, 250,000 sq mi). Texas has the Chihuahuan Desert in the west and Llano Estacado plateau. Both have significant coastlines (Texas Gulf of Mexico; Saudi Red Sea + Persian Gulf), and both produce most of their petroleum from sedimentary basins.
Saudi Arabia is dramatically hotter on average. Summer temperatures in Riyadh average 110°F (43°C); record highs reach 124°F (51°C). Texas summer averages 95°F (35°C) in Dallas/Houston, with record highs around 120°F (49°C) in remote areas. Saudi's deserts have lower humidity but higher daytime temperatures.
Saudi Arabia (830,000 sq mi) is approximately 1.45× the size of Alaska (570,641 sq mi) or 3.18× Texas. It's larger than Alaska alone, the next-closest US state by area. Saudi + Texas combined ≈ 1.10 million sq mi — bigger than the entire state of Alaska.
Saudi Arabia is approximately the size of Mexico × 1.09, Greenland × 0.99, Iran × 1.31, or Texas + Alaska combined × 0.99. Among countries, it ranks 12th by area (between Algeria and Mexico).
Roughly 95% of Saudi Arabia is uninhabited desert. The population is concentrated in the western Hejaz region (Mecca, Medina, Jeddah), the central Najd plateau (Riyadh), and the eastern oil region (Dammam, Dhahran). The Rub' al Khali in the southeast is one of the most hostile environments on Earth — temperatures regularly exceed 130°F, no permanent settlements, sand dunes hundreds of feet tall.
