# How Many Inches Are In A Square Foot?

There are 144 sq in in a square foot. You get this answer by multiplying how many inches there are in a foot, which is 12, by itself (because it is a square so all the sides are of equal length). So, 12 x 12 equals 144.

A square foot is an imperial unit of measurement (in America it is called a U.S. Customary unit) of area and is very often used to measure areas within houses or other buildings. Square yards and square metres are also commonly used in these instances, with a square metre being a metric measurement.

A square foot is often seen represented by the abbreviation, ‘sq ft’, but in architecture or interior design plans it can often be seen as a symbol comprising of a square with a slash through it.

To work out the total square footage of a room is easy to do. You need to measure the length and the breadth of the room and then multiply the two numbers together. For example if a room measured 14 ft by 20 ft, you multiply 14 by 20, which will give you a total of 280 (14 x 20 = 280). You now know the square footage of that particular room.

If you need to calculate the square footage of an entire house, or other building, simply calculate the square footage of each individual room and then add them all together. Naturally, this rule applies if you want your measurements to be in square yards or square metres too. Just remember that a yard is three ft or 36 in, and that a metre is a 100 cm (or roughly 39 in if you need a metric measurement but do not have a metric rule).

1 foot = 12 inches.

1 square foot = 12 x 12 = 144 square inches.

There are not inches in a square foot, there are "square inches".
