Enter the total square footage of the land parcel and the total square footage of the building to determine the land to building ratio.This calculator can also determine the land or building area when given the other variables.

## Land to Building Ratio Formula

The following formula is used to calculate a land to building ratio:

L:B = AL / AB
• Where L:B is the land to building ratio
• AL is the area of the land (ft^2)
• AB is the area of the building (ft^2)

To calculate the land to building ratio, divide the area of the land by the area of the building.

## What is land to building ratio?

Definition:

A land to building ratio is defined as the total square footage of a land parcel divided by the total area of the building footprint.

The land to building ratio is used in real estate to evaluate how much land is taken up by a building to determine if there is room for my development.

## How to calculate a land to building ratio?

Example Problem:

The following example outlines how to calculate a land to building ratio.

First, determine the total square footage taken up by the building. In this case, the total land area is 5000 square feet.

Next, determine the area of the entire lot. In this example, the entire lot of land is 10,000 square feet.

Finally, calculate the land to building ratio using the formula above:

L:B = AL / AB

L:B = 10,000 / 5,000

L:B = 2:1
