Thank you, I think I'm getting there 🙂 I'll give it a go and see what happens.

Sorry for not making it more clear. The way I portrayed it is not very mathematically correct. It's meant to be easier understood even if you don't understand math.

45cm is the base length you need for a string in a 14cm long bracelet.

To that base length you add 1 cm per percent. For example, if you have 50%, you add 50cm.

45cm+50cm=95cm

If you are trying to calculate it for a bracelet of a different length, you have to calculate the base length for that length and you need to multiply the percentage with the bracelet length divided by 14. It's just a lucky coincidence that 1% correlates with 1cm of string in a 14cm long bracelet.

Hi, I'll preface this with a honest admission, I have dyscalculia and struggle with numbers but I wanted to get my head round this. When I struggled I asked my husband who does get numbers and he couldn't figure it out either. So with the calculation for string one you say:

"Length of string 1 = 45cm + 50% = 95cm"

Which I assumed meant you ad half of 45 to 45 but that only gives 67.5. I'm just not seeing how to get 95?

So sorry for being slow witted with this but it looks such a useful skill to have and be able to not waste, or run out of thread.

TIA

I made a google sheets calculator using your formula. Is there somewhere I can post it for people to test out?

fantastic, thank you so much for sharing the formula!!!!! Worked perfectly with #166980. Would you by chance have a clue how to calculate for special patterns like for example #145574? Because I figured out that the for these loop-like bracelets, outer threads require extra lengths.

So, how can I use this formula with pattern #192159?

What a fantastic formula! I used it for pattern #197862 and it worked out perfectly, even though I calculated a different bracelet length. Thank you so muc, you are truly amazing!!! 🙂

This is SO COOL you were able to figure this out!!! I'm definitely going to take it into consideration when making bracelets in the future!

@whoistaji I must have made a mistake. The 100 needs to be outside the bracket or on top. You're right.

hiya, i have a clarification question "percentage of knots made = number of knots : (number of rows x 100)"
so lets say there were 16 rows and 8 knots made. would the formula plug in be: 8/(16*100) which would equal 5 percent? tbh ive just been doing it as (8/16)*100...

@str6yk1ds the formula is for ties on each end as stated in the beginning. Each tie uses 10cm.

You can adjust the formula to fit whatever amount of string you'd need for a loop.

This formula does not include shaped starts.

Does this include the amount of string needed for ties on each end and/or a loop or shaped start?

@ElliElli you look at where the arrow is coming from. If the arrow follows the string, the knot belongs to that string.

You can also use "add a variation" to make the strings two different colours to see more clearly.

@halokiwi thank you very much! Just one last question, in case the string colors overlap, like in the string 2 and 4, how to distinguish which knot belongs to the correct string? To avoid miscounting.

Hi! Sorry to bother but how exactly does one count the knots? That’s the only confusing part for me. Per example in the string 2 I count four knots instead of three, how does one know when a knot does not belong? I got confused because I count the knot in row 6 as belonging to the string 2 instead of the string 4. I tried

@user254780

You just put 16 anywhere it says "length of bracelet"

length of string = length needed for ties + square root of (2 x (length of bracelet^2)) + percentage of knots made with that string x (length of bracelet/14)

would turn into

length of string = length needed for ties + square root of (2 x (16^2)) + percentage of knots made with that string x (16/14)

length of string = length needed for ties + square root of (2 x (256)) + percentage of knots made with that string x 1,14

length of string = length needed for ties + square root of 512 + percentage of knots made with that string x 1,14

length of string = length needed for ties + 22,63 + percentage of knots made with that string x 1,14

But I think you figured that out yourself too 😄
