A square foot or sq ft is one imperial unit of area the is widely offered in the joined States, Canada, China, and also the unified Kingdom. Its symbol is a basic square through a vertical line bisecting it (), commonly used in numerous branches, such together architecture, real estate, and also interior space plans. It may also be sometimes written together a square with a slash v it. Its abbreviation is commonly composed as sqft or sq ft.

As a unit of area, it has actually a magnitude tantamount to the area that a square through sides the 1 foot. This size provides it advantageous to talk around the area of day-to-day objects such together a home (typically 500-1000 sq ft), a room (~100 sq ft) and even one A4 piece of paper (0.65 sq ft) without having actually to usage either very huge or very small numbers. Over there exist, obviously, other devices of area that deserve to express the exact same magnitude as the sq ft and also might even be an ext suitable for very tiny objects (like the square inch), very huge objects (like the acre), or to just to interact with the remainder of the civilization by using the standardized SI/Metric units (whose default unit the area is the square meter).

You will see soon exactly how to transform from square meters to square feet, indigenous square inches to square feet, etc... But for now, let"s talk about some situations in i m sorry you might want to calculate the square footage the something using a basic square footage formula. These situations include selling, leasing, renting, or to buy a residence or a room; building a shed or a garage for your car; or maybe even when paint a room. In every these situations, our square footage calculator will help you. Although, for the critical three, us recommend looking in ~ our repaint calculator.


Technically, it is not correct to talk around the square footage formula; we have to rather talk about area formula. However, as lengthy as we know that a square clip formula is simply another method to say that we will certainly take an area formula and also apply it using square feet, i think we deserve to all agree the an exact technical hatchet doesn"t matter much here.

The square clip formula is different depending on the shape of the object we want to calculate the area for. The simplest and also most usual case is the square, or, an ext generally, the rectangle. Because that these polygons, the formula is as basic as acquisition the length of two nearby sides in feet and also multiplying castle together. Since we space working with a rectangle, we know that taking two next sides is the same as taking the height and the width of it. If us name these two sides A and also B, the other two necessarily must have the exact same dimensions as A and B, respectively.

square_footage = length_A * length_B

This could sound favor a simple mathematics formula, but it is specifically how to measure the square clip of a rectangular room in actual life. We simply need come measure two consecutive political parties in feet and multiply the values together. This square clip formula is, in fact, the very same as the one provided in the area that a rectangle calculator, but, in instance of this calculator, offered to discover square footage instead of calculating polygons.

Not all rooms space perfect squares or rectangles, and it becomes more tricky to calculate square footage in together a situation. If the room is nearly rectangular, one can gain a pretty an excellent approximation simply by considering it together a rectangular and also performing a similar calculation as we have actually seen before. But when the form of the room (or every little thing you desire to measure) is far from rectangular, we absolutely recommend utilizing the corresponding Omni calculator for that shape,e.g., it could be a triangle area calculator, the area the a circle calculator, or any other shape.Note the these calculators because that geometrical shapes can calculate locations in nearly any unit you would wish for. This method that friend can convert from acres to sq ft, to square meters, come square feet, and so on, utilizing the same procedure that we have explained in the ahead section.


Once again, we tackle a widespread worry that, regardless of the symptom which might arise in real life, has actually some rather straightforward maths in ~ it. The calculations that square clip pricing are, mathematically, the simple department of the price the a details property by its complete square footage. In everyday life, this value changes significantly relying on such determinants as a location of the property, to plan or potential use, and also so on. It is nevertheless a useful amount to advice the value that a particular house or property.

Before we speak a bit an ext about the usefulness the this measurement, let"s take a look at at how we have the right to use this calculator as soon as square footage pricing comes right into play. First, make sure that the "One room/area" alternative is selected in ~ the optimal of the calculator. The area can be calculated in the previous procedures or can also be inputted by the user. Then either the price per sq ft or the full cost must be provided to attain the other value. Let"s look in ~ a complete example:Input the dimension of the property"s (or property chunk"s) width and also length in your preferred units,Input the number of properties/chunks the the residential or commercial property with the dimension input above, entry the total area in your wanted units,Input the total pricing that the property,Obtain the square clip pricing as dollars (or your regional currency) every sq ft.

This is an instance of one of the most straightforward scenarios, but it is an extremely representative of the usual uses of this square clip calculator. We think that it is essential not just to know just how to calculate square footage or just how to measure up square clip but likewise to understand what you can do with those values once you gain them.

When it pertains to square clip pricing, the usefulness depends on the reality that it allows to compare properties (mostly houses) of different sizes and also prices. It"s the equivalent of performance per dollar charts of computer parts, for example. In this manner, one can compare a 1500 sq ft through a 500 sq ft and also know i m sorry one represents a far better real state option, looking beyond just the price or the size of them. In fact, this have the right to be offered with any other area unit with or there is no converting from square meter to square feet or acre to square feet - every time we want to do a fair comparison.


We have touched previously on how to calculate and also measure square footage in a simple situation favor a rectangle-shaped room/house or a circular and also triangular... However there are cases in i beg your pardon the shape of the residential property we desire to measure square clip from, is a bit much more complicated than that. In those cases there are two options: (1) utilizing the area that a polygon calculator and also other comparable calculators by Omni (we deserve to recommend the hexagon / octagon area calculators or (2) gain creative, as we"re gonna carry out now.

For very facility and rarely often, rarely shapes, there is no an easy recipe for how to measure up the square footage of a home using just one tool. However, we deserve to use a an easy trick to achieve the suitable result. Us can shot to decompose the area right into several tiny pieces that have a constant shape, because that which we have the right to calculate square footage. To each of those pieces, we apply the square clip formula equivalent to that polygonal form (different Omni Calculators will certainly prove beneficial here). If we then add up the an outcome from every piece, us will acquire the total square footage of the house, no matter its shape.

There is a possibility that the residence will have rounded corners that curvy forms (they are very popular nowadays), and this can seem impossible to do. But in reality, one can gain a very an excellent approximation making use of a right line that goes come the middle of the curved ones or, if we want to be more precise, many small polygons. It could be time-consuming, but it simultaneously deserve to be as accurate as one needs.
