Your piece is half done. And the cord ran out.
You measured, you cut, you dove in all excited. Halfway through, that doubt creeps back: is it going to be enough?
Which of these have you said before?
- I did the math and got it way, way off.
- Ran out of cord for the knotting at the end. So the end never got finished.
- I've got so much cord sitting here because I overestimated and had leftovers.
- Messed up the math on a bag and had to undo it 3x.
- Couldn't find how to calculate cord anywhere. Anyone know where to look?
- You really have to think the math through.
- And the leftovers weren't enough to make anything.
When you run short, the order stalls and you're scrambling for more cord.
When you have too much, your money just sits in a drawer.
As one maker in the group put it:
“Hard on your patience, hard on your wallet.”
You've tried everything to get that math right
And every option let you down in its own way.
Someone else's numbers
They were worked out with someone else's hands. If you knot tighter or looser, the cord won't add up.
The spreadsheet
If you're not a spreadsheet person, you're stuck. Delete one formula by accident and the whole result changes.
Rules of thumb
They assume you know where to start. If your starting number is off, your cord comes out wrong at the end.
Asking in a group
Everyone gives you a different answer, and your order sits on hold.
She was right. Without a test, the math is a guess.
But nobody has time to test every piece from scratch with a customer waiting. That's why I made a calculator that saves your tests and does the math for you.
The math follows your hands and your tension
Every maker knots a little differently. That's why the calculator learns from you.
- 1
You tie a small test piece: your sample.
Using your knot, your cord and your tension. Then you measure what's left on the 4 strands.
- 2
The calculator does the math.
It works out how much cord your hands use for that knot and saves your sample.
- 3
Every new piece uses your sample automatically.
Same knot, same thickness: it picks it up on its own. If you have several, it uses the average.
- The cutting list: how many cords to cut and how long each one should be.
- How much cord your hands use, saved for your next pieces.
- The list as a PDF, image or text, so you can cut without doing any math.
I checked the calculator against the Ágape Skirt
I'd written down in my notebook how much cord the 6 cm waistband took. Then I ran the same piece through the calculator and compared.
6 cm waistband
- Working cord (ties the knots)
- 0 cm0 cm
- Filler cord (runs down the center)
- 0 cm0 cm
For both cords, the calculator allowed a little more than the piece actually used. That difference is the safety margin: it's set to 20% by default, and you can lower it to 10%. A small margin, and it's your call.

You're looking for a pattern, a template or step-by-step instructions for a piece.
You want to figure out the selling price for your piece.That's my next product.
You want to learn how to tie the knots.The calculator does the cord math. It doesn't teach macrame.

I used to struggle with cord math, too.
I'm Bru, and I love this creative, special world of knots made by hand. I've been doing macrame for 3 years, I set up my own studio, and I love making pieces for everyday use.
But the math was always the hard part. On my very first piece, a lampshade, I had tons of cord left over because I got the math wrong. Since then, I write down how much cord each knot uses, and I've learned that every pair of hands is different. Now I make tools that save you time and keep you from losing money.
Now those notes fit right on your phone.Bruna

No. The calculator starts with the table I measured knot by knot. Once you make your own samples, it switches to your hands.
The calculator accepts 3 to 8 mm cord and adjusts the number of cords to the thickness. My table was measured with 4 mm cord. For exact knot usage with a different cord, make a sample.
Both. It's set to inches, feet and yards, and you can switch to centimeters and meters on the home screen. Cord thickness stays in millimeters, since that's how cord is sold.
