How to Figure Out the Square Footage of a Home

Definition of Sq. Footage

Sq. footage is a measurement of space, and space is the measurement of any two-dimensional area contained inside a set of traces. Consider it within the sense of a dance flooring. Take a second to think about a dance flooring that’s 20 toes by 20 toes (6.09 meters by 6.09 meters). How can we specific the world that it takes up? This one is simple, as a result of the dance flooring is a sq.. We merely multiply the width of the ground by the size of the ground, 20 toes occasions 20 toes equals 400 sq. toes. Subsequently, the whole space of the dance flooring is 400 sq. toes (37.2 sq. meters). The equation is similar for a rectangle [source: MCWDN].

Space of a sq. or rectangle = Width x Size


It is necessary to remember the fact that a sq. foot would not essentially should be formed like a sq.. The dance flooring above could possibly be formed like a triangle and canopy the identical quantity of space. In case you had been requested to find out the world of a triangle or a circle, the equation could be completely different, however the idea is similar. Plug in the correct numbers and you will get the correct reply. Each equations are listed beneath.

Space of a triangle = ½ (Base x Top)

Space of a circle = 3.14 x radius2

So we have established that the sq. in sq. toes would not consult with form. All measurements of space are expressed in sq. models — the usual foot simply occurs to be the unit utilized in U.S. actual property.

It is Hip to Be Sq.­­ Most homes are formed like rectangles or squares, which makes calculating the sq. footage straightforward, whether or not you are measuring outdoors or inside the house. However what if you’ll want to measure inside a home that has an odd variety of partitions and corners that aren’t 90 levels? That doesn’t should be tough both.

Learn how to Determine Out the Sq. Footage of Non-Rectangular Rooms

When you’ve got a room that’s not an ideal rectangle – perhaps it has a sq. space hooked up – simply divide it into separate rectangles, calculate the sq. footage for every of them, and add up their totals such as you would with the remainder of your home.

Nonetheless, some houses have areas that aren’t rectangular.

Learn how to Determine Out the Sq. Footage of a Semicircle

For instance, you could possibly have a semicircle coming off of a room to provide a panoramic view of the encircling space.

In that case, measure the road that makes up the straight portion of the semicircle.

Then, divide it by two, so you will have the radius (r).

Plug that quantity into the equation for a circle’s area: πr2.

Lastly, divide the reply by two.

So, should you measure the straight line and it equals 10 toes, you’d divide that by 2, getting 5 toes.

After you sq. 5 toes, you’d have 25 toes after which, multiplying it by π, you’d arrive at 78.54 toes. Divide that by 2 and you’ve got your sq. footage for the semicircular area: 39.27 toes.

Learn how to Determine Out the Sq. Footage of a Triangular Area

Does the home in query embody a triangular area?

In that case, flip the triangle right into a proper triangle by beginning on the tallest level and slicing it down the center (if it’s already a proper triangle, skip that step).

Then, multiply the peak by the bottom and divide that quantity by two. That’s it. That’s the sq. footage of the triangular area.

In case you needed to minimize your triangle in half, simply discover the sq. footage for each and add them collectively.

When doubtful, ask the professionals

If calculating the sq. toes of your explicit property feels overwhelming, contemplate hiring an expert appraiser to do it. The typical appraisal value for a single-family dwelling usually runs about $350. A condominium appraisal price is mostly between $300 and $500, and multi-family dwelling value determinations can run anyplace from $600 to $1,500.

Whereas two completely different skilled appraisers may consider the identical dwelling and give you barely completely different sq. footage figures, they do all goal for scientific accuracy. “We’re all the time capturing for someplace between 1 to three % variance,” Day says.

How a lot to permit for waste?

To permit for waste, you should contemplate the set up.  For most traditional installations, 10% further for waste is ample.  Proportion of waste for extra elaborate patterns like working tile on a 45 diploma angle, herringbone or cross hatch, seek the advice of along with your installer. Add 15% for tile being put in in a room with plenty of jogs and corners. These installations would require extra cuts and thus extra waste.

Size x Width + Waste = Quantity Wanted

Learn how to calculate the sq. footage of a home

When making ready to measure the sq. footage of a house, be it a house, condo, or townhouse, begin with just a few easy provides:

  • Paper and pencil
  • Calculator
  • Measuring tape and/or laser measuring device

If the property is an ideal rectangle, merely measure the size and width and multiply these two numbers collectively. For instance, in case your one-story home is 60 toes broad by 40 toes lengthy, then your property is 2,400 sq. toes (60 x 40 = 2,400).

Nonetheless, most properties have extra complicated flooring plans. When that is the case, it’s useful to comply with these easy steps to measure sq. footage.

  1. Draw a tough sketch of your complete area, labeling all the rooms you’ll want to measure. Embrace hallways and vestibules as their very own “room.”
  2. Measure the size and width, in toes, of every room. Then, multiply the size by the width to calculate that room’s sq. footage. For instance: If a bed room is 12 toes by 20 toes, it’s 240 sq. toes (12 x 20 = 240). For every room, write the whole sq. footage within the corresponding area in your sketch.
  3. As soon as every room is measured, add up all of the measurements to find out your property’s whole sq. footage.

Notice In case you reside in a tract dwelling, condominium or townhome neighborhood, you could possibly get architectural drawings or grasp builder plans of your flooring plan. These might have already got your sq. footage calculated.

Convert amongst sq. inch, sq. foot, sq. yard and sq. meter

What number of sq. toes is a 20×20 room?

The sq. footage of a room measuring 20 toes broad by 20 toes lengthy is 400 sq. toes. To calculate this you merely multiply the width by the peak. 20ft × 20ft = 400 sq ft.

When you’ve gathered sq. footage (minus non-cleanable areas) for all rooms, add them collectively. This quantity is your whole sq. footage that must be cleaned.

You possibly can take this course of a step additional and add cleansing prices to the equation. Multiply whole washable sq. footage by a base value for cleansing. For example, in case your whole space to be cleaned is 5,000 sq. toes and the worth per sq. foot is 25 cents, you possibly can multiply $0.25 occasions 5,000 to get a complete of $1,250 for cleansing charges.
