How big is a manzana? About 1.73 acres, and here's why

The first time we saw "manzana" on a listing

We spent about forty years in the States. Square feet and acres were the only land units that meant anything to us. We knew we wanted an alternative as the climate kept changing, but leaving the country was never really on the table.

Then we came to El Salvador to see family and reconnect with our roots. Somewhere during that visit we fell in love with the place, and we realized this was the alternative we'd been looking for.

So we started looking at property. The listings said things like "2 manzanas" or "850 varas cuadradas," and honestly, we couldn't tell whether that meant a backyard or a farm. Every website we checked explained it a little differently.

That confusion is where our calculator came from. We built the tool we wished we'd had on day one.

So what exactly is a manzana?

A manzana is a square measuring 100 varas on each side. The vara is an old Spanish unit about 83.6 cm long, roughly 33 inches. So a manzana is a square about 83.6 meters, or 274 feet, on each side.

100 varas times 100 varas gives you 10,000 square varas, exactly. That clean number is the whole definition, and it's the one thing everyone in Central America agrees on.

To picture it: a manzana is about one and a third American football fields, end zones included.

Why is it called a manzana?

Yes, manzana also means apple. The land unit and the city block share the name for a reason, though. When Spain founded cities in the Americas, it laid out buildings inside squares of 100 varas per side, with room for a street on each edge. Those squares were called manzanas, and they were the same size as the farmland unit. That's why across much of Latin America "una manzana" still means a city block. How the word for apple ended up there in the first place, nobody fully agrees, and we won't pretend to know.

Same name, slightly different size

Every Central American country defines the manzana as 10,000 square varas. The catch is that each country's vara is a tiny bit different, so the metric size shifts:

If you're ever comparing property across borders, compare in square meters. It's the only unit that means the same thing everywhere.

How manzanas show up in a Salvadoran deed

Salvadoran deeds (escrituras) often mix units in one sentence. You might read something like "una manzana cinco mil setecientas cincuenta y cinco varas cuadradas." That means 1 manzana plus 5,755 square varas, for a total of 15,755 square varas: about 11,011 m², or roughly 2.72 acres.

A bit of history explains the mix. The Central American countries agreed to adopt the metric system back in 1910, and official land records work in metric today. But manzanas and varas never left everyday conversation, so you'll see both, sometimes in the same document.

One more number worth knowing

El Salvador's Constitution limits how much rural land one person can own to 245 hectares. That's about 350 manzanas. Most buyers will never come close, but it's a good example of why it helps to be comfortable with both units.
