Turk’s Head Size Reference

I love knots because they’re technical & creative. At the heart of every knot is math – something I’m still learning. Because the Turk’s Head is the base for so many other knots, it helps to know the math. It’s pretty simple and once you see it visually, it’s easy to remember.

The Rules

Bights & parts cannot be equal (5B 5L).

Bights & parts cannot share a multiple. (6B 9L share a multiple of 3).

Bights & parts cannot both be even because they share a multiple of 2.

A prime number of bights & parts is always possible – except for equal numbers.

Additional passes do not change the number of bights and parts – a doubled 5B 7P Turk’s Head is still 5B 7P.

The Visuals

Bights: Narrow to wide

Parts: Short to long

Prime Number

Not Possible

Square: Nearly equal bights & parts

Wide: More bights than parts

Tall: More parts than bights
