Can this calculator handle L-shaped or irregular rooms?

No, the tool only tests two axis-aligned straight-strip orientations. Irregular shapes require a measured carpet plan or professional layout.

What does the cutting and matching allowance cover?

The allowance percentage covers trimming and simple matching before conversion to linear yards, helping account for waste from cutting and aligning carpet strips.

How are linear yards calculated from room dimensions?

Linear yards equal the minimum of the two straight-strip plans, multiplied by the allowance factor, then divided by three to convert feet to yards.

Does the tool consider patterned carpet or pile direction?

No, the calculator does not include pattern repeat, pile direction, door seams, or room joins. A measured carpet plan is needed for those factors.

About this tool

What Carpet Calculator does

A Carpet Calculator that estimates the linear yards of carpet needed by comparing two straight-strip layouts based on room dimensions and roll width. Users enter room length, room width, carpet roll width, and a cutting and matching allowance percentage. The tool outputs the shorter straight-strip length, the total length with allowance applied, an approximate seam count, and the resulting linear yards. The result is derived from a transparent formula that rounds full roll-width strips first, then converts footage to yards by dividing by three. The page also includes a control example and notes on assumptions, helping users verify their project requirements against the calculated output.

Step by step

How to use the GQ Calc Carpet Calculator

1
Enter the room length in feet
2
Enter the room width in feet
3
Input the carpet roll width in feet
4
Set the cutting and matching allowance percentage
5
Review the output for linear yards, total length with allowance, and approximate seam count

Is it right for you

Best for

DIY renovators and small contractors who need a quick, transparent estimate of carpet linear yards for standard rectangular rooms without patterned repeats.

Limitations

Results assume straight-strip layouts only
Patterned carpet and room joins are not accounted for
Linear yard output depends on user-entered allowance percentage
