What's the size of 400 acres? How big are 400 acres? Width and length of a rectangular area. An acre is 43,560 square feet.

1 square mile = 640 acres
A quarter square mile = 160 acres
A standard residential lot = .2 acres, often 132ft x 66ft

Type the acreage and one side in feet. The calculator will show the dimensions.

How to Calculate
To calculate the dimenions of 400 acres, you need to know one side of the dimenions. This formula is used for rectangular areas only. For example, if you have 400 acres, you can convert 400 acres to 17424000 square feet. Let's say that one side is 3615 feet. You can then divide the square footage by the known side.
400 acres x 43,560 / 3615 feet = 4819.92 ft
To calculate acreage when you know the dimensions, use the following formula. Take one side (in feet) of the area and multiply it by the other side (in feet). This will give you the square footage. Since there are 43,560 square feet in an acre, you then divide the square footage by 43,560.
(Side 1 in Feet x Side 2 in Feet) / 43,560 = acres
How to Use
I use this calculator to get a quick estimate of the dimensions for a specific acreage, usually for land size but also state parks, lakes, and other properties that use acreage as a measurement. Type the number of acres into the calculator and one side. You'll get a quick idea of the dimensions of 400 acres.
