When contacting FDP to make a carpet request it can be very helpful
to have a ROUGH idea of how much carpet you will be needing.
To help you estimate how much carpet you may need and approximate the possible cost for budgeting
purposes we have included a little background information. Ninety percent of broadloom carpet is
manufactured in rolls 12 feet wide. (Ocasionally 15 ft widths or other sizes may be available, but usually
LESS THAN 12 ft WIDE, If the area you are carpeting is carpet is ordered in 12 foot roll widths.)
(or if you are purchasing CARPET TILES) then measuring for carpet is easy to calculate and instructions
are given in the section below.
Measuring for Carpet IN AREAS LESS THAN 12 FEET WIDE & for Carpet Tiles
(Rough Estimate Only)
In order to calculate the amount of carpet you need for a room you first need to calculate
the total square feet of the area you want to cover. To determine a floor's square footage,
multiply the length times the width in feet. When measuring, round UP to the nearest foot
measuring both the longest and the widest part of the room (and halfway out into all doorways).
Measuring for Carpet In Areas GREATER than 12 ft Wide (Rough Estimate Only)
If you have a room that is wider than 12 feet you will need to have a seam(s). And this is where
measuring gets more complicated and should be calculated by your carpet professional.
Ideally you want to minimize the amount of seams as much as possible.
EXAMPLE: You want to carpet an area 16 feet wide x 16 feet long using a 12 foot wide roll of carpet.
The main piece of carpet would be 12 ft wide (the width of the roll) x 16 foot long.
Since the room is 16 ft wide an additional 4 ft wide by 16 ft long strip will have to be seamed
along side. (16 ft wide room - 12 ft wide roll = 4 additional feet on the side)
To install with only one seam, you would have to order a 34 foot length of carpet.
Here is the breakdown: one 12 foot x 16 foot main piece + one 12 ft x 16 foot piece
(to cut a 4 foot side piece) plus 1 foot to each length to cover irregularites***
(16 + 1) + (16 + 1) = 34 ft length x 12 foot roll
For irregularly shaped floors: (Rough Estimate Only)
Sketch a floorplan. Square off all areas into individual sections.
(Be sure to measure into doorways.) Once in individual sections,
measure each section with a tape measure, writing down the
Length & Width of each area on your floor plan. Calculate the square
footage in each section by multiplying the L x W in each section.
To determine your TOTAL square footage just add all the individual
For Stairs: (Rough Estimate Only)
Total Square Footage of Stairs = ( # of steps x 2) x Width of Steps
Measure the Width of the stairway. (Round inches UP to the nearest foot).
Length = the number of steps in the stairway multiplied by 2 (feet).
