There used to be a formula for this and now I can't find it--anyone remember???

I've heard 36 inches (1 yard) per string before, but that works best for average-sized wrists in a pattern that uses all the strings equally. I personally use the length from my shoulder to my hand, and I always have extra string, but I have really small wrists.

I usually do it the length of one arm

I made that formula a few years back in this the 'other' section of the forums. I'll see if I can find it again and if not I'm pretty sure I wrote it down somewhere to do a video on it.

An admin might delete this because I've copied and pasted it from the old post I made before but here's the formula with explanation:

So I realise looking back on this thread that there's a lot of people who aren't great at algebra or don't know it to understand what's going on so I'll try to explain it.

THIS:
(length of string used in proper knots x number of knots in colour y) + (physical size of finished knot x all knots colour y passes under) + length for desired ties + (overhand knot x 2) + length of string for physical loop + length of string for after final knot = perfect string length

is our formula.

This formula uses BEDMAS, I don't know where everyone is at with math so I'll give a quick explanation of that. BEDMAS is the order of operations and stands for Brackets, Exponents, Division, Multiplication, Addition, Subtraction. So when you look at a formula like the one above you follow the order of BEDMAS. So first you look for brackets, so anything encased in (these). If you look at our formula, there's a few. So let's break it down:

Our first bracket is this:

(length of string used in proper knots x number of knots in colour y)

So to figure this out you need to get out some string and tie a couple rows of knots as if you were making a bracelet. Then using a pen mark as close as you can to the top of your knotting string. Tie a knot as if you were making a bracelet, mark the top of your knotting string as close to your knot you just made as possible. Now untie your knot and measure. I suggest doing this a few times to make sure you're accurate. So for example, we'll say it measured 1cm. PS. All of these lengths are made up off of the top of my head for example purposes only.

Now our formula looks like this:

(1cm x number of knots in colour y)

So now you look at whatever pattern you're doing and pick a colour we'll say red, though it doesn't really matter. This is the colour you are measuring for now. Count the amount of knots that appear in the pattern in that colour. Let's pretend it's 50. Our finished first bracket looks like this now:

(1cm x 50)

so let's move onto the next one which is this one:

(physical size of finished knot x all knots colour y passes under)

So get out those couple rows you tied before and your ruler again. Now we're going to measure the size of your physical knot top to bottom. Let's say it's 1mm aka 0.1cm. So let's put that in and look at our bracket:

(0.1cm x all knots colour y passes under)

Now, if you remember 'colour y' we said was red. So you're going to look at your pattern and follow where your red string goes and count all the knots the string goes UNDER. This does not include the times the red is the colour of the knot. Let's say it goes under 80 knots. Our bracket looks like this now:

(0.1cm x 80) making the first bit of our formula look like this: (1cm x 50) + (0.1cm x 80) + length for desired ties

The next bracket:

(overhand knot x 2)

Your overhand knot is the knot used to make the loop at the top of your bracelet. It is the same type of knot used to tie off the braids at the end so using the same method we did for the knots in our pattern, measure the length of string you use in your overhand knots. We'll say it's 2cm. Your formula looks like this:

(2cm x 2) making the formula look like this:

(1cm x 50) + (1mm x 80) + length for desired ties + (2cm x 2)+ length of string for physical loop + length of string for after final knot = perfect string length

The next parts to fill in are easy. Measure how long you would like your finishing braids/ties to be and put that number in where it says 'length for desired ties' -let's say 5cm. Measure the amount of string you want in your starting loop and put it in where it says 'length of string for physical loop'- let's say 2cm. Then add the small bit of string that hands at the end of your braids, after your knot- we'll say 1.5 cm.

WOO YOU'RE ALMOST THERE!

So now we're into some math. Remember BEDMAS? We're going to follow that now. So we're going to do the math in the brackets first. So first bracket is 50 x 1 = 50
50 + (0.1cm x 80) + 5cm + (2cm x 2) + 2cm + 1.5cm = perfect string length.
Second is 0.1 x 80 = 8
50 + 8 + 5cm + (2cm x 2) + 2cm + 1.5cm = perfect string length.
Last bracket is 2cm x 2 = 4
50 + 8 + 5cm + 4 + 2cm + 1.5cm = perfect string length.

Now we're into simple addition! 😄

50 + 8 = 58
58 + 5 + 4 + 2 + 1.5 = string length
63 + 5 = 68
68 + 4 + 2 + 1.5 = string length
68 + 4 = 72
72 + 2 + 1.5 = string length
72 + 2 = 74
74 + 1.5 = string length
75.5

TADA! Your perfect string length would be 75.5 cm for ONE COLOUR! Apply again for all colours and adjust for fancy beginnings and endings.

I also made a video of how to do this on my YouTube channel if the written instruction doesn’t make sense!

I usually just do my arm length. It works basically perfect

@Apeanut41 like the length of one arm or your whole wingspan?

@nschuit this formula & explanation should help you figure out exact length.

@Andyish right? But when I originally posted I didn’t explain it and no one understood it 😂
