Here is the formula.
Carpet gauge vs face weight.
Weight and carpet style.
For most commercial applications a carpet density of 4 000 to.
The last consideration is face weight weight of the carpet pile per square yard.
Fiber face weight is not the same as total carpet weight which includes the weight of the carpet backing and the fiber face weight.
Factors that may affect the minimum face weight needed are how often the room is used the carpet s twist level and the carpet s density.
You can have a carpet with virtually no twist or one with 5 twists.
Obviously styles of carpet are constructed differently and you cannot make comparisons of two different construction styles based solely on face weight for example berbers tend to have lower face weights than saxonies because of their low pile and relatively low number of fibers a very good quality berber carpet might have the same face weight as a saxony of.
Never choose a carpet that has less than 20 oz face weight.
A carpet s density is a measure of the weight of the pile yarn corrected for the height of the yarn.
Pile height the thickness of the carpet from the backing to the surface is one of the factors that determines the face weight of your carpet.
Carpets with higher face weights of over 40 oz are going to be more resilient and longer lasting than those on the lower end of the scale.
A carpet with a low density number risks uglying out before it actually wears out.
Depending on other features of your carpet a lower or higher face weight may be required.
As a general rule the shorter the carpet pile and the lower the face weight the more durable it is as it s less likely the yarn will crush and show signs of wear due to foot traffic.
Density is also influenced by the number of tufts per inch when counting across a width of carpet.
The face weight refers to the amount of ounces of fiber per square yard and the more the better.
The higher this number the denser the carpet.
For example a 35 ounce face weight carpet with a half inch pile height would have a pile density rating of 2520 35 x 36 divided by 5 2520.
Fiber face weight x 36 divided by pile height in decimal form pile density.
A higher face weight means more yarn says grable and more yarn makes for a longer lasting product as an example within one product line the good level carpet has a face weight of 40 oz.

Twist is the number of twists in the yarn per inch.
You want at least a 35 ounce face weight carpet for maximum durability.
The gauge of a machine does not change but the stitch rate can.
So a 1 10 gauge carpet with 10 stitches per inch means there are 100 stitches in one square inch of the carpet.
For high quality carpet face weight is typically 32 ounces per square yard or higher.
Most carpets have a face weight somewhere between 20 ounces and 100 ounces but the average face weight for a residential carpet is about 35 to 60 ounces.
