Pricing carpet for stairs?

Question

My stairs are 15' long and 3.25' wide. Do most carpets come in 15' widths? Or will I be charged for a 12' width x 15' long?

Answer 1

The rise and run of steps are measured by measuring the tread and riser of each step. This will give you the linear feet of carpet that you need to cover the steps. They will use a 12' wide piece of carpeting if that is the only area you are doing. They will cut it into 3-4 strips that are a 3'4". The will install them with tack strips and put pad on the tread. For a full flight of 12-13 steps you will need at least a 12' x 7' piece of carpet to cover the flight of stairs. Labor to install stairs is higher than flat work. There will also be a minimum charge for the installer to come to the house.

Good luck with your project.

Answer 2

The carpet will not be installed using the width, running across the staircase..

The direction of the nap must run down the steps. You do not want the carpet to grin.

If the total length of the steps and risers is 15' and the width is 3' 4", the carpet needed will be 12' X 5'. That may not be accurate.
Risers and step are usually 1'6"-1'8".

I'm estimating a 12' X 5.0".
That is 6 2/3 sq. yards.
This will be stripped into 3 strips, each 4'.0 X 5'.0.

If 15' carpet is used, it may take a 15'.0 X 3'9", 6 2/3 sq. yds.
This will be stripped into 4 strips, each 3' 9" X 3'9".

Do not depend on this for accurate measurements. I'm not sure how accurate you are.
It should give you an idea.
