How much cord do macrame knots use?

Square knots typically use 4 times the finished length. Spiral knots use about 4.5 times. Half hitches use about 3.5 times. Berry knots are the most cord-intensive at around 5 times the finished length.

Should I add extra cord for mistakes?

Yes, always add 10-15% extra cord. It is much better to have leftover cord than to run short mid-project. For beginners, add 20% extra.

What cord thickness should I use?

For wall hangings, 3-5 mm cord is most popular. For plant hangers, 4-6 mm works well. For small jewellery or keyrings, 1-2 mm cord gives fine detail. Thicker cord creates bolder, more visible knots.

Does cord type affect how much I need?

Yes. Braided cord is less stretchy and maintains its length well. Single twist cord can stretch 5-10% over time. Cotton cord tightens with use while synthetic cord stays consistent.

How do I calculate for a mixed-knot project?

Divide your project into sections by knot type. Calculate each section separately using the appropriate multiplier, then add them together plus fringe and mounting allowances.

How We Calculate This

How the Calculation Works

Each type of macrame knot consumes a different amount of cord relative to the finished length. The calculator applies a multiplier based on the knot type:

Square knots: 4x | Spiral knots: 4.5x | Half hitches: 3.5x | Berry knots: 5x | Gathering knots: 3x

The formula is: cord per strand = (finished length x multiplier) + fringe length + mounting allowance. Total cord = cord per strand x number of strands.
