## Calculator Use

Use this calculator to find the square footage, square inches, square yardage, square meters or acres for a building, home, garden or construction project. Calculate square footage, inches, yardage, meters and acres for landscape, flooring, carpet, or tiling projects to estimate area and the amount of material you will need. Also calculate the cost of materials when you enter the price per square foot, price per square inch, price per square yard or price per square meter.

Price is entered in the fields, for example, as $ price: 3.00 per: 1 square unit: foot (ft²) meaning $3.00 per 1 square foot or $ price: 25.00 per: 1000 square unit: foot (ft²) meaning $25.00 per 1000 square feet etc ….

If you want to calculate volume of bulk materials such as mulch or gravel you should use our calculator for cubic yards and cubic meters.

Enter measurements in US units or metric units. Calculate area from your measurements in inches (in), feet (ft), yards (yd), millimeters (mm), centimeters (cm), or meters (m). You can also enter decimal values. For example, if you have one measurement that is 7’3" you can enter that as 7.25 feet (3"/12" = 0.25 ft). If you have a measurement of 245 cm you can also enter that as 2.45 m.

## What to leave out

A good rule of thumb to ensure you’re taking proper measurements is to exclude space you can’t walk on or live in. These types of spaces do not count as “gross living area.”

“Someone might think, ‘If I get the measurement of my first floor and I have a two-story house, I just multiply that by two,’” Day says. However, if that first floor includes a two-story foyer, you can’t count the non-usable space.

Basements and garages, even if they are finished, don’t generally count toward total square footage. Basements are typically excluded because they are built below grade, meaning below ground level. If your state does allow basements to be included in the total square footage of a home, though, you’ll likely need an ingress and egress, or a safe way to enter and exit the basement to the outside.

Finished attic spaces — with some regulations, including ceiling heights — can count toward the total square footage of your home. If you are planning to sell your home, work with a real estate agent to craft a listing that accurately reflects your property.

## How much to allow for waste?

To allow for waste, you must consider the installation. For most standard installations, 10% extra for waste is sufficient. Percentage of waste for more elaborate patterns like running tile on a 45 degree angle, herringbone or cross hatch, consult with your installer. Add 15% for tile being installed in a room with lots of jogs and corners. These installations will require more cuts and thus more waste.

Length x Width + Waste = Amount Needed

## How to find the square footage of a rectangle

- Measure the
**width**and**length**of the area in feet. - Multiply your length and width together to get your area.

Note: If your measurements aren't in feet, convert them to feet first using our length converter.

Once you've carried out your calculation, you will have your square feet (ft^{2}) figure. To calculate your cost of materials, simply multiply this figure by your price per square foot.

## How many square feet is a 12×12 room?

The square footage of a room measuring 12 feet wide by 12 feet long is **144 square feet**. To calculate this you simply multiply the width by the height. 12ft × 12ft = 144 sq ft.

## Convert among square inch, square foot, square yard and square meter

You could, for example, perform all of your measurements in inches or centimeters, calculate area in square inches or square centimeters then convert your final answer to the unit you need such as square feet or square meters.

To convert among square feet, yards and meters use the following conversion factors. For other units use our calculator for area conversions.

## How to calculate how many pieces of bullnose you will need?

If you have ten feet exposed edge that needs bullnose this is equal to 120″. If you selected a 6″ bullnose or trim piece, you will need to divide 120″ by 6″, which will give you 20 pieces of bullnose needed. Using 8″ decorative liner for the same 120″, you divide 120″ by 8″ which would be 15 pieces of liner needed.

## How to Measure for Laminate Flooring in 3 Steps

Determining how much laminate flooring you need to buy is relatively simple, but it pays to measure properly. Just follow these basic steps.

**Step 1:** Figure out the square footage of each room in which you want to install laminate-wood floors. To do so, use a tape measure to determine the room’s length and width. Then multiply the length by the width to get your square footage. For instance, if the room is 12 feet wide and 12 feet long, you will need enough flooring for 144 square feet (12×12=144).

**Step 2: **Add 10% to the square footage to accommodate cuts and waste. (If you’re choosing a tile pattern, add 20%). This is important because the cuts in the flooring need to be staggered. And you’ll want pieces left over just in case you need to mend or replace a board. So that’s 144 feet plus 10%, or 14 feet, for 158 square feet.
