Hi Ed, Roof shinges are measure by the square which equals 100 square feet and usually comes packaged as 3 or 4 bundles of asphalt shingles. To find out how many squares you need, multiply the width of the area times the length in feet and divide by 100 (i.e. 20'w x 10'h = 200 sq. ft. ÷ 100 = 2 squares). It's usually a good idea to add 1% to 5% in for waste. You can find out more about roofs and roofing in our article How to Choose a Roof for Your Home.

Danny,

need the correct formula to calculate measurements for replacing shingles on a roof. How many yards do I need for the job. (e.g.) 50×14 = Sq Yrds?

Thanks, Ed

Hi Donna,
To find the number of cubic cubic yards of concrete needed, multilply the length x width x depth in yards (or fractions of a yard). One cubic yard of concrete equals a volume of 3′ x 3′ x 3′, which is the same as 27 cubic feet, so you can also measure it in feet (or fractions of a foot), then divide the total by 27 to find the number of yards. For example, to calculate the yards of concrete needed for a slab 12′ x 12′ x 4″, multiply 12 x 12 x 0.33 = 47.52 cubic feet ÷ 27 = 1.76 yards. Another way of thinking about it, is that a 4″ thick slab 9′ x 9′ equals one yard of concrete.

Kathy,
Depending on how many nooks and crannies there are, you can either subtract the parts that are not included from the whole, or divide the room up into various sections and add the square feet for each of them together.

How do I find the required amount of carpet when my rooms all run together? The main floor of my Townhouse is all open. Do I take the dimensions of the entire floor and subtract the SQ ft of the unuseable space (like the open stairs, bath, foyer and kitchen)?

Lee,
To find the number of square feet or square yards in your room, just type the dimensions of your room in the boxes above and click on the calculate button.
If you want do the calculations yourself, the formula is:
width x length = square feet
Divide that number by 9 to get the number of square yards.

Am I missing something. The instructions don’t say how to calculate amount of carpet, wood flooring, tile etc. needed.

Do you multiply the width X Depth and divide by three to get square yards etc.

It has been so long since I have figured how to do this that I have forgotten.

Sorry if I seem so dense, but I need to measure for wood flooring for my upstairs.

Thanks for your help.
