Mexico vs Texas Size: How Much Bigger Is Mexico?

By SimpleMapLab·Published 15 May 2026·Reviewed against CIA Factbook + US Census·CC-BY 4.0

Mexico covers 758,449 sq mi (1.96 million km²). Texas covers 268,596 sq mi (695,662 km²). Mexico is 2.82× larger — almost three Texases fit inside. The two share a 1,254-mile border via the Rio Grande. Until 1836, Texas WAS Mexican; it was independent for nearly 10 years, then became the 28th US state in 1845, triggering the Mexican-American War.

How much bigger is Mexico than Texas?

Mexico is 2.82 times larger than Texas by total area — about 490,000 sq mi more land. That gap alone is bigger than Alaska (570,641 sq mi minus Texas) or roughly two Californias. Almost three Texases stacked together would fit inside Mexico, with about 16% of one extra Texas worth of land left over.

Population-wise, Mexico has 4.24× Texas's population (129M vs 30M). That makes Mexico 1.45× denser, since the area ratio is only 2.82× — population grew faster than land. Both have most of their population in metropolitan areas: Mexico City's metro (~22 million) is by itself bigger than the entire Texas Triangle (Houston + Dallas-Fort Worth + San Antonio + Austin combined, ~20 million).

Texas was Mexican: 1821-1836

Today's Texas-Mexico border is the most famous of the post-1848 era — but the deeper history is that Texas was a Mexican state from 1821 to 1836. After Mexican independence from Spain (1821), the territory was called “Coahuila y Tejas” — a combined Mexican state of two regions. Mexico encouraged American immigration to Texas (the Stephen F. Austin colonies, starting 1825) to populate the underdeveloped northern frontier.

By 1830, Anglo settlers outnumbered Mexican Texans 3:1, and tensions over slavery, religion, and political autonomy mounted. The Texas Revolution (October 1835 – April 1836) ended with the Battle of San Jacinto (Apr 21, 1836) — Santa Anna captured, Texas independence achieved. The Republic of Texas existed as a sovereign nation from March 2, 1836 to December 29, 1845 — nine years and nine months.

US annexation of Texas (Dec 29, 1845) triggered the Mexican-American War (1846–1848). The war ended with the Treaty of Guadalupe Hidalgo, which transferred 525,000 sq mi of Mexican territory to the US (the “Mexican Cession”) — making California, Nevada, Utah, most of Arizona and New Mexico, parts of Colorado and Wyoming part of the United States. See Mexico vs USA for the full transfer.

Economic reversal: Texas earns more than Mexico

Despite Mexico being 2.82× larger and 4.24× more populous, Texas's economy is 1.41× the size of Mexico's. Texas GDP (2024): $2.6 trillion — would rank #8 globally as a country. Mexico GDP: $1.85 trillion — #15 globally. Per capita: Texas ~$85,000 vs Mexico ~$14,300 — a 5.9× gap reflecting the wage difference between US states and Latin American economies.

The Texas–Mexico economic relationship is enormous: Mexico is Texas's #1 trading partner ($288 billion in goods trade, 2024). Texas ports (Houston, Brownsville, Laredo) handle most US-Mexico land trade. The two economies are deeply integrated despite the wide per-capita gap.

Frequently asked questions

Yes. Mexico covers 758,449 sq mi (1,964,375 km²); Texas covers 268,596 sq mi (695,662 km²). Mexico is 2.82 times larger by total area. Almost three Texases fit inside Mexico — close to a clean integer.
Mexico is 2.82× larger — a difference of about 490,000 sq mi. That difference is roughly equal to the size of Alaska (570,641 sq mi) or about 2× California.
Yes. Texas was a Mexican state ("Coahuila y Tejas") from 1821 (Mexican independence from Spain) to 1836 (Texas Revolution and independence as the Republic of Texas). Texas operated as an independent country for nearly 10 years (1836–1845), then was annexed by the United States in December 1845 as the 28th state. The annexation triggered the Mexican-American War (1846–1848), which ended with the Treaty of Guadalupe Hidalgo and the Mexican Cession.
The Mexico-Texas border is 1,254 miles long, forming the southern boundary of Texas via the Rio Grande River (called Río Bravo del Norte in Mexico). This is the longest US-Mexico state border. The Rio Grande border was established by the 1848 Treaty of Guadalupe Hidalgo after the Mexican-American War.
Mexico has approximately 129.4 million people; Texas has 30.5 million. Mexico has 4.24× Texas's population. Density: Mexico 170/sq mi vs Texas 117/sq mi — Mexico is 1.45× denser. The Mexico City metropolitan area alone (~22 million) is bigger than the entire Texas Triangle (Houston + Dallas + San Antonio + Austin combined, ~20 million).
Texas. Texas GDP (2024): $2.6 trillion. Mexico GDP: $1.85 trillion. Texas's economy is 1.41× Mexico's despite being one-third the area and one-fourth the population. Per capita: Texas ~$85,000 vs Mexico ~$14,300. The gap reflects US vs Mexico wage differences and Texas's concentration of high-margin sectors (tech, finance, energy, agriculture, aerospace).
Mexico has 31 states + Mexico City (CDMX) = 32 federal entities. Texas has 254 counties (the most of any US state). Mexican states average ~24,000 sq mi (similar to West Virginia); Texas counties average ~1,070 sq mi (similar to Rhode Island).
Mexico: 5,797 mi of coastline (Pacific on the west + Caribbean/Gulf on the east). Texas: 367 mi of Gulf of Mexico coastline. Mexico has 15.8× more coast than Texas. Mexico is on two oceans; Texas has one shoreline.
Mexico is approximately the size of Indonesia × 1.03, Saudi Arabia × 0.91, Greenland × 0.91, or Iran × 1.19. Among countries, Mexico ranks 13th by area.
The Republic of Texas (1836–1845) claimed approximately 389,000 sq mi at its peak — including the Texas Panhandle and parts of present-day New Mexico, Colorado, Oklahoma, Kansas, and Wyoming. After US annexation (1845) and the 1850 Compromise of 1850 (which ceded the northwestern territory to the US in exchange for $10 million), Texas shrank to its modern 268,596 sq mi.
