League and Labor

The league (Spanish legua) and the labor are land measurement units inherited from Spanish colonial Texas. They still define the size of named-survey polygons throughout South Texas, the Rio Grande Valley, and parts of Central Texas — anywhere that traces back to Spanish, Mexican, or early Republic-of-Texas land grants.

League

A league is approximately 4,428.4 acres — about 7 square miles. Geometrically it is a square 5,000 varas on each side.

Spanish and later Mexican authorities granted leagues primarily for cattle ranching. A family that could occupy and ranch one league of frontier land could claim it as a sitio de ganado mayor (a cattle grazing site). Empresario contracts in the 1820s and 1830s — where colonization agents brought settlers into Texas — typically included multiple leagues per family settled.

After Texas independence in 1836 and statehood in 1845, the Republic and the State continued to issue grants in leagues to honor the inherited Spanish system and to maintain continuity. Many South Texas ranches today still occupy areas measured in original leagues.

Labor

A labor is approximately 177.1 acres — exactly 1/25 of a league. Geometrically it is a square 1,000 varas on each side.

Labors were granted for farming, not ranching. The smaller size reflects what a single family could realistically cultivate without livestock. A typical Mexican-era empresario grant gave a settler "a league and a labor" — a few thousand acres of grazing land for cattle plus around 177 acres of farmable land near a water source.

Vara

A vara is about 33.33 inches — roughly a yard, but slightly less. It is the underlying linear unit for all Spanish colonial land measurement in Texas. Survey field notes from the era measure distances in varas:

• A league is 5,000 varas on each side
• A labor is 1,000 varas on each side
• A "section" in modern Block & Section TXSS is often described in field notes as ~1,900 varas on each side (one mile)

How Leagues and Labors Appear Today

You will rarely see "league" or "labor" written out in a modern legal description. Instead, the original league or labor is named after its grantee and referenced as a survey:

John Smith Survey, Webb County

If you look up that survey in GLO records, the field notes will tell you whether it was originally granted as a league, a labor, or some combination.

When Township America computes acreage for a survey-name reference, the returned value reflects the actual polygon — so a single-league grant comes back as ~4,400 acres and a single-labor grant as ~177 acres, give or take what the original surveyor measured.

Why This Matters

For PLSS users coming to Texas work, the league/labor history is the answer to a common puzzle: "Why are these surveys all weirdly sized — some 4,400 acres, others 177, others totally irregular?" The sizes are not random; they trace back to the colonial-era grant categories. Recognizing a league or a labor in the survey size is a quick way to date the original grant.
