Enter the total number of knots and the area of fabric (cm^2) into the Knot Density Calculator. The calculator will evaluate and display the Knot Density. 

Knot Density Formula

The following formula is used to calculate the Knot Density. 

KD = #K / AF

  • Where KD is the Knot Density (knots/cm^2)
  • #K is the total number of knots 
  • AF is the area of fabric (cm^2) 

How to Calculate Knot Density?

The following example problems outline how to calculate Knot Density.

Example Problem #1:

  1. First, determine the total number of knots. 
    1. The total number of knots is given as: 700.
  2. Next, determine the area of fabric (cm^2). 
    1. The area of fabric (cm^2) is provided as: 20.
  3. Finally, calculate the Knot Density using the equation above: 

KD = #K / AF

The values given above are inserted into the equation below:

KD = 700 / 20 = 35 (knots/cm^2)


Example Problem #2: 

For this problem, the variables needed are provided below:

total number of knots = 1045

area of fabric (cm^2) = 501

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer. 

KD = #K / AF = ?
