This turks head knot is a massive 41 bight x 21 part design which measures about 10" (253 mm) inside circumference in it's current relaxed state. This one will stretch to about 11 1/2". Here you can see the distinctive overlapping pattern. The core-less para cord lies flat. A para cord with 5 or 7 strand cores would be much thicker and stiffer than this example.
