If you had a room 12'6" X 18' How many yards will you need? Using only one seam. Please show your math.
Thanks for your advice. This question was on a Nationwide test. And I am curious if I got it correct.

Can I buy 14' or 15' wide carpet? Then there would be no seams.
If I could only use 12' wide carpet, I would estimate 33.3 sy.
24 x 12.5 = 300 sf/9 = 33.3 sy

| I was there too. Did the exam say just one seam? I calculated (12*12,6)+ (6*12)= 222sq ft. = 24.666 sq yds. That is with two seams, cut and roll. |

| I have been shown the "roll"? method of measuring carpet probably a hundred times but I still can't get it figured out. I just give them the 10% waste factor and be done with it. Does anyone have a idea of how far off this type of measuring may be by like % points or something. I believe I have been told the "roll"? method is more accurate but by how much or by how much is the 10% waste factor less accurate. Somebody help me out here because I don't think I am making any sense. |

First draw a pretty little picture of a 12'6" x 18' room. Split the room into a 12'6" by 12' area and a 5'6" by 12'6" area. Delineate it with a dotted line. That line is the seam. Working with 12' wide carpet, multiply 12 X 12.5= 150. Multiply 12.5 X 5.5= 68.75. Add 150 + 68.75=218.75/9=24.3yds.
Is that what you get, or has my logic gone to s--t? |

Ghost, I don't see the logic in your 12.5 x 5.5????? yep, it may be in the pot! I get the same as Jennifer. The confusion usually comes in with the fraction of a foot over the normal width of the carpet, i.e., in this case the 12.5 room width. You have to focus on dropping it. No matter what, the room is 18 feet long and it will take 2 drops of the room width to cover it. Yes, you do end up with a ton of waste. Can't be helped using this method and the required single seam. If they would allow you to use 2 seams the waste factor would be almost zero.
MCaldwell--there is no area of 6 x 12--there is a 6 x 12.5. You would come up short by 6 inches all across the width of the room.
Ghost--your's is short too! we are trying to cover a floor not make a mini dress!
You have to buy twice the width of your room! |

| The answer is 25 sq yrds or 225 sq ft. 12x12.5 and 6x12.5 You end up with 75 sq ft of waste but that is the least wasteful way to do it with only one seam. if you did it the other direction you would end up with 207 sq feet of waste (18*11.5). Unless you wanted to lay the carpet diagnolly. |

Are we trying to determine how much carpet (carpet only) that has to be bought or are we trying to figure out how much it is going to cost to carpet the room based on the amount of carpet needed or purchased.
Professional carpet installers use the drop and roll method to determine the amount of carpet (carpet only) that has to be purchased. To make a correct calculation the room has to be measured and the width of the roll has to be known. Then such things as furniture moving, tack strips, pad and removal and installation have to be considered. Generally I try to find the seam in the old carpet and use it as a guide.
The second method is to measure the room and add 10% waste and use the provided prices in your estimating program.
It is a good idea to carry a knife and a large baggie and take an ITEL sample anytime you pay for carpet. Keep in mind that most new carpet is completely synthetic and clear water, hot or cold, does not harm it, replace the pad and clean and restretch the carpet. |

I still stand by my calculation. If the carpet has a nap it is the only way to do it so all of the naps lay right.

| 12'6 x 12' and 6' x 12'6 = 18'6" x 1.33 = 24.61 yds. One seam. |

Another tip is to carry a butane lighter and use it to rule out natural fiber, wool or cotton, and the carpet could be a jacquard loom.

RBECKINTEXAS- (I was sitting next to you at the conference I think.)
The key to the question was the fact that the room was 12'6" wide which required the seam in the middle (or 12' out from one end of the 18' room). We are assuming that no 15' wide roll was available. Contrary to a prior post showing you can buy a piece 6' x 12'6" to finish out the room, you will be required to buy a run 25' long by 12' wide. (For the purpose of the test I did not add a waste factor) Rather than calculate out 25 x 12 divided by 9, a easy and quick way is to multiply the 25 times 1.33. (1' of carpet 12' wide equals 1.33 yards.) My answer was 33.25 yards.
If there are openings going into other rooms, you will sometimes need to check the direction of the lay to determine what you go back with. Always imagine working in blocks of 12' widths. Once you start laying in a certain direction, you have to maintain that for consistency. I have never seen industry acceptance of a 'butt' joint for carpeting except in a doorway.
Has anyone else?
(Some carriers have started making their adjusters calculate the removal of the carpet at the actual square footage and allowing for the replacement only with the 'drop & fill' approach. Similar to what is being done with roofing.)

Another estimating point is that carpet installers measure the width of the room from the middle of the doorway to the opposite wall.
The "drop and roll" method is only to determine the amount of carpet to buy and has nothing to do with carpet removal, pad removal,pad replacement, tack strips, subfloor preparation, moving furniture or the amount of carpet to be laid. In a "drop and roll" estimate these are seperate line items. |

Whoa, Hoss. Your right! My brain needs an overhaul. The tearoff would be 25 yards, the installation would be 25 yards, the amount of carpet material to be bought would be 33 yards. The amount of pad would be 225 SQ feet. Pad is sold in 6' widths.
The waste amount of carpet, (6'x12.5'), (if it's a long purple shag), can be used to line the bed of the claim managers truck. |
