How Much Macramé Cord Do I Need? A Practical Guide to Measuring and Cutting

Few things are more frustrating in macramé than running out of cord three rows from the bottom of a wall hanging. The opposite problem, cutting far too much, wastes money and leaves you with a pile of offcuts. The good news is that estimating how much macrame cord you need is a skill you can learn with a few rules of thumb and a little planning. This guide explains how to think about cord length, cord count and total quantity, whether you are following a pattern or designing your own piece.

Why knots eat so much cord

Every knot bends cord around other cords. A square knot’s working cords travel sideways and loop back, so they use several times more length than the filler cords at their center. A dense area of double half hitches uses even more. That is why a finished wall hanging that is 60 cm long might need individual cords several meters long. The more knots you tie, and the thicker the cord, the more length each knot consumes.

Start with the pattern, if you have one

If you are following a written pattern, it should list the cord thickness, the number of cords and the length of each. For example, a pattern might say “16 cords of 134 inches” for the main cords and “32 cords of 36 inches” for fringe. Stick closely to the specified cord thickness. If you swap 3 mm cord for 5 mm cord, your knots will be larger, the finished piece will be wider and longer, and you will need more cord overall.

It is also wise to cut slightly longer than the pattern states, particularly if you tie tightly. An extra 10 to 20 percent is a common safety margin, and leftovers can always become fringe, tassels or keychains.

Rules of thumb when designing your own piece

Makers use a handful of rough ratios as a starting point. They are estimates, not laws, because every maker’s tension and every design is different.

The finished-length multiplier

• Light knotting with lots of open space and fringe: cut each cord roughly 3 to 4 times the finished length.
• Moderate knotting, such as rows of alternating square knots with some gaps: cut about 4 to 5 times the finished length.
• Dense knotting, such as solid areas of double half hitches: cut 6 times the finished length or more.

Remember the fold

Most wall hangings and plant hangers mount cords with a lark’s head knot, which folds each cord in half. That means one cut length becomes two working ends. If you want each hanging end to be four times the finished length, cut each cord to eight times the finished length before folding. Forgetting this is the most common reason beginners run short.

Working cords versus filler cords

In a sinnet of square knots, the two outer working cords do all the traveling while the two center fillers barely move. For long sinnets, such as plant hanger arms, some makers cut the working cords longer than the fillers, or swap positions partway down so the cords are used more evenly.

How many cords do you need?

Length is only half the question. The number of cords determines how wide your piece will be.

1. Decide the finished width, often the length of your dowel minus a little on each side.
2. Measure how wide one mounted cord is. Tie a lark’s head with your chosen cord and measure its width. With 4 mm to 5 mm cord, one lark’s head is often around 1 cm, but check your own.
3. Divide the width by the knot width. A 40 cm wide piece with 1 cm lark’s heads needs about 40 lark’s heads.
4. Round to your pattern’s grouping. Square knots work in groups of four ends, and each folded cord gives two ends, so one square knot uses two folded cords. Choose an even number of folded cords so every row divides cleanly.

Make a test swatch

The single most reliable way to estimate cord is to test. Cut four cords to a known length, say 100 cm each, mount them and tie a short section of the knot pattern you plan to use, for example 10 cm of alternating square knots. Then measure how much cord remains on each end.

If 10 cm of finished knotting used 45 cm of working cord, your ratio for that pattern is 4.5 to 1. Multiply by your planned knotted length, add the length of any fringe you want at the bottom, and add a margin for finishing. A swatch takes fifteen minutes and can save you an entire reknot.

Calculating total cord to buy

Once you know how many cords and how long each is, the total is simple multiplication. Suppose you need 20 cords, each cut to 4 m: that is 80 m of cord. Add any separate pieces, such as a wrapping cord for a gathering knot or a hanging cord for the dowel, then add 10 percent for mistakes. Cord is often sold by the meter, yard or by weight, so convert units before you order.

A quick worked example

You want a wall hanging about 50 cm long, excluding fringe, with moderate knotting and a 15 cm fringe.

• Knotted section: 50 cm x 4.5 = 225 cm per hanging end.
• Add fringe: 225 + 15 = 240 cm per end.
• Add a small margin: about 260 cm per end.
• Double it for the lark’s head fold: 520 cm, so cut each cord to about 5.2 m.
• With 16 folded cords, that is roughly 83 m, plus extra for the hanging cord.

Cord type changes the math

Not all cords behave the same. Single-strand (twisted) cotton is soft, combs into fluffy fringe and packs tightly, so knots tend to be compact. 3-ply cord is a rope of three twisted strands; it holds a crisp shape and unravels into wavy fringe, but it can use a little more length per knot. Braided cord is smooth and strong, good for plant hangers and outdoor pieces, yet it does not fringe well and its knots can sit slightly larger. Thicker cords of any type consume more length per knot than thinner ones. Whenever you change cord type or thickness, redo your test swatch instead of reusing an old ratio.

What to do when you run short

It happens to everyone eventually. You have a few options:

• Swap working and filler cords so the longer fillers become working cords.
• Add a new cord by hiding its end inside a sinnet or behind a row of double half hitches, then trim once secure.
• Redesign the bottom by ending the knotting earlier and turning the remaining length into fringe.

Adding cords neatly is a skill in itself. Our in-depth guide Macramé: Achieving Perfection covers selecting cord, measuring length and width, preparing cords, adding cords and finishing techniques, which is exactly where these rules of thumb become second nature.

Keep records of every project

The best estimates come from your own history. Each time you finish a piece, write down the cord thickness, how many cords you used, how long you cut them and how much was left over. After a few projects you will have personal ratios that are far more accurate than any general rule. The printable Macramé Project Planner includes project sheets and an inventory table designed for exactly this kind of note-taking.

If you would rather start with patterns that already give exact cut lengths, every project in The Macramé Bible lists its cord thickness, count and length before the first step, so you can shop and cut with confidence and spend your time knotting.
