Paracord bracelet math formulas_reduce your scrap
Вставка
- Опубліковано 27 січ 2013
- After making paracord bracelets and watching various videos, and reading comments, people have asked how much cord do they need to make a particular bracelet.
I came up with these math formulas to make the Solomon's bar. The Caterpillar feet braid. The Oak spike sinnet, & the Tire tread bar.
These formulas are for the length of the bracelet, including the side release buckle (3/8).
Hopefully this will save you from using too much cord, which results in excessive waste.
If you want any other formulas for other types of bracelets, please suggest in the comment box below.

This worked great!!!! Totally reduced my amount of waste cord! I now only trim 1" to 2" of excess cord!!! Thank you for posting this!
Thank you for taking the time to do this video. No formula is perfect for everyone, as you mentioned, but this is a great starting point. Hope Stormy's collar has a easy release on it. If not, it could be fatal. I read about one person who thought making the collar loose would solve the problem. However, her cat manged to get the collar caught between the upper and lower jaw and the cat choked to death. Don't let anything like that happen to Stormy.
Thank you folks for you aptitude of mathematics. You Mr. Fuller helped me out tremendously.
Thanks for the formula's! I will try the Solomon today.
Great video my friend, thank you so much for all the help!
Best wishes

You can also use your scraps for core cords (the parts that run between buckles that the other cords wrap around). The ones around 16 inches can be doubled for a two cord core, the 8 inch or so can be melted to the same/diff. color to make a two-cord core, etc, on top of making fishing lures, zipper pulls, tiny keychains, parabuddies, etc.
Dragon's Claw, Fishtail and piranha please, sir. Thank you so much for the others!
Thank you. I found your video most helpful.
Wow, can't wait to test these formulas out. The Tire Tread in JD's book p. 112 , he says to use two 7 foot lengths for a 7.5 inch bracelet. That would only fit a 7 inch wrist, according to a chart I found.Your formula for a 7.5 inch bracelet uses only 5 ft. for primary length and 4 feet for the secondary length cord. Quite a savings of 5 feet of cord. I am impressed. Good work !
triumphmanful 6ft-7ft would be all you need for your standard cobra variation knots, however getting into or attempting any new designs out there floating around will require 10ft+ each color/cord (normally includes the core) for 7in-8in wrist size. Thickness will always add more length. Test your lengths and record for the proper tension at the end. All these numbers you see are simply guidelines or suggestions. YOU decide the final length needed for your project. Use common sense and you'll never come up short or waste. Good luck and have fun cording or knotting.
I love that you figured this out and tried to share it. Would have loved to see your spreadsheet but the email you shared bounced :(
Yeah sorry about that. My computer died. And after 7 years I got a laptop. I'll try to see if I can pull the spreadsheet off the old hard drive. If I can I'll let you know. I'm in a better place now. I started this to occupy my time while looking after my wife of 23 years who was battling cancer. Unfortunately she did not make it. And after that, I kinda went away for some years. After 7 years, I've had a special person who helped me thru the pain and loneliness. I will try to get back to this and maybe post some new stuff. Thank you for asking about the spreadsheet. Thank you and have a good day .
Hi Bowfinger, you know what else would be really helpful that I haven't been able to hit on yet? A formula to tell you exactly how much length you need to add to fit a certain size of wrist. My wrist is 6.5-7 inches, but the oatspike sinnet I wear measures out to be an 8 on my jig. Whereas a Portuguese Sinnet measures out to 7.5 on the jig. You always hear to add .75 to 1.25 blah blah. I think any tyer would agree that the better the fit, the happier the customer. Just a thought.
Excellent. Thank you.
Great tutorial! Thanks!
Will save me tons of money and profit in my pocket. Thanks for the tutorial. I would like to see for the fishbone weave if you get time.
Saved me a ton of cord, thanks!
All that "waste" is useful for smaller paracord projects like zipper pulls or keychain tabs. It adds to the profit.
I used 6" x Y + Y on ea color for snake knot and it was perfect!
This is extremely helpful , im just starting to add paracord items to my bow shop and this will be soooo helpful! waste is the death profit of a small bus, lol :-) THANKS FOR ALL YOUR HARD WORK!!
I would love to see one for Stitched Solomon Bar :-)
thank you this very helpful.
Thank s Amanda. I come up with 377.10023" for the primary color ( I would round up to 390") and 190.56" for the secondary (again round up to 210")
as for finishing with a buckle, I just melted the cord against the buckle ( so it acts like a stop- however I would suggest watching Mrcoop1967's video on making the oat spike with a buckle, excellent video. thanks again & have an awesome day!
this is a 2 part question first can you find the formula for a 5ft dog leash in the oat spike and second how did you finish the oat spike with the buckle
Thank you for this video! Will be making a milepede (quick deploy) 2 color bracelet with a straight buckle. Would u have the computation for this please?
Was watching this vid with all seriousness then at 1:28 made me smile! Thanks for this vid, really helped. Kisses and pats to ur catty too :)
You're very welcome, Brianna. I agree. Too much waste, can be a death kneel for a beginning Entrepreneur, as inventory costs eat into profit margins. say, you make 10 bracelets, using 10' of cord per bracelet, when you can make them using 8'. wasting 20' of cord. when you could have made an additional 2 1/2 bracelets. it can add up quickly. I will try to remember your suggestion in a future video, as the next one is almost done. Fishtail, dragons tongue, shark jaw bone, Aztec sun braid are in.
Ok, I have a question about measuring for bigger projects. First off let me say that this video was very helpful. I screen-shotted the formulas so I could use them for reference. Thanks for that! I want to make a bow shoulder sling for my bow. I would like to use carabiners at each end. Slip the whole thing through the bow and clip the carabiner around the sling itself. This is just for carrying it. How do you figure out how much paracord to use if you want the sling to be 4 ft long when you are finished without a ton of waste? I'm content using the cobra weave because it's the one I am comfortable using. I have wrist slings that we bought, I will probably make my own. How do you attach the cords to the carabiners and not have the weave come loose? Any suggestions or advice would be greatly appreciated. Thanks so much!!!
Greetings, I ask if you have come up with any other formulas? If so what are they? And if can you do the ladder rack knot?
Glad you found it helpful.
to all the rest of you waiting for a part 2.
my stupid camera froze up, waiting on the replacement.
Thanks to all for the support--Charles
Nice video. Question. What would the math formula be for a king cobra bracelet with 2 colours using one continues strand of each colour. No stops and restarts. From bringing to end.
yeah, could've used another 12" on the secondary :) (probably another 12" on the primary as well) maybe i should've taken my braiding strength into consideration. you did point it out on the video, and i think i might've subconsciously ignored it. Thanks for the formula, it did give me a base idea of the length i needed. keep up the good work.
I wanna do a Viper Paracord Bracelet an my wrist measured out at 10 1/4 in .how much paracord would i need ?
You're very welcome. that was the whole point, so that people can save on cordage, and make more pieces. Part 2 is out. and one on the snake braid is almost done-stay tuned.
Thank you ,Sue
I have done the Aztec sun bar. I will see if I can put that one in.
I should be almost ready to post a part 2.
Wow! didn't think this would be so popular. Thanks to everyone for watching, Subbing, and all the thumbs, very much appreciated
you can always make parapeeps, and sell them, and you can add hearts and ribbons to bracelets for cancer and other meanings, i've seen the vid here
Thank you, sir. Your video is super helpful and cost saving for those of us on limited budgets!
Would you happen to know the formulas for the Trilobite and the Aztec Sun Bar, as well????
Thank you again and have a great summer, keep cool.
Thank you
You're welcome.
can you figure out the double cobra
Hey everyone,could someone tell me how much Paracord for1foot of box Knot weave ?Thank you
is it true that the langth of rope needed is just hoe long the bracelet is?
***** those scraps can be used for zipper pulls or small keychains!
thats what i do...
you bet, lots of thing one could do. paracord jelly fish keychains are my favorite. making fishing lures is another one I like.
How about the King Cobra weave, do i just double the length of each color?
Thanks for the tutorial...do you have one for a King Cobra using a ParaClaw Buckle?
Gregory Miyata hmm. You bring up a good point, I measured at the point of attachment from one piece of the Buckle to the other, and had one next to the inch that allows for the buckle. I'll try to get back to you with a formula for that that does not allow for the width of the buckle just the finished braided part. You said king cobra that's with Cobra weave double back on itself correct? Can you send me a link to your para claw buckle. Thank you
Thank you for watching Yondaime flash.
MrCoop1967 has a most excellent video on making the oat spike with a buckle, that said he does his a bit different then J.D does. he incorporates a 2 strand core from the secondary color, so be sure to include that into your math.
Using the formula of oak spike, how I can do it with the buckle?
Is that a paracord collar on your cat? If so, awesome!
Can someone explain loop please, think I know what it is but am not exactly sure
H ow would I calculate if i had a 8.4 wrist just saying
well, on this video, I was using 3/8" buckle ( the width of the buckle)
these 4 formulas included the buckle( which was the 1 inch length that the buckle made when clasped). IE; a 7" bracelet was 6" of braiding PLUS the
1 inch that the buckle made.
What I did not take into account, was that different buckles have different lengths.
All other videos will have the formulas made for finished braid length only.
So yes, I would add other 1" - 1.5" to your Variable "Y"
Thanks for that question.
Hi..trying to do a hex nut bracelet....would you have the formula for this type bracelet? Your video is extremely helpful. Thank you!
Not familiar with it, What type of knot is the Base? I:e Solomans bar, or catapiller braid,. If it's one of this listed. perhaps add 1.5" to the formula. example= instead of 4.5" per inch-per strand, make it 6" per inch.
I calculated it and it seems to work, given that I haven’t made a bracelet using this formula. Is the total of all of these in feet?
In inches.
Say you're doing the Solomons bar
(4.5inches of stand to make an 8 inch bracelet ) per cord/color.
(4.5 × 8") + 8 = 44 inches or 3.6666667 feet.
Measuring in inches is more accurate or at least easier.
Hope that helps.
Hi I'd like to clarify something. Will there be an additional inch for the loops on the buckles? I saw a video says 6 inch bracelet needs 7.5 feet of paracord 0.0 and with your computation i got 6 inch bracelet needs 5.5 feet. Its a lot of difference
Hello Eggy, the loop that goes thru the buckle is about 3 inchs long.
Not sure what braid you're talking about. let me know so I can help you figure it out
uhm im trying to do a normal cobra weave :)
so with wht i have computed, i need to add another 3 inch along with length i have computed with your formula?
Ok the cobra (reg.) uses about 4 & 1/2 inchs per color/strand, for every inch of finished braid, plus the length of the braid in your case six inches, so, IE:6 ". 4.5 x 6 + 6 equals 33 inches of each color, or 66 inches if using one whole strand, so just add 6 more inches ( 3 per 'loop' heck add a foot, then measure your drop if it's more then a foot left, the formula works for you, if less, then add a little more to the Multiplier ( the 4.5")
this is a excel formula, put it in a cell, make the "y" the cell you enter your length.
=sum(4.5 * y + y) remember, it is for one strand, in a two strand (normally) braid.
Do u use the same formula for the wide/double cobra
+Noah J which one? the "King" cobra.
Or a double wide reg solomon's' bar interweave?
The fat cobra that's starts out as a reg, then doubles back onto itself is the "king cobra"
well. the first part does appy, but when going back over for the second pass, the formula won't work. since I've never done one, I can't give you a true number to use, but if you're willing to try:
=SUM(4.5* Y + Y) +SUM ( 9 * Y ) per color/strand.
let me know if it works, and how much it's over, or short, on a piece of how long. Thanks
when i make the shark tooth braid,i use 9' cord for 81/2'' projct.and either i end up with way too much extra,or not enough,or if i un-braid and do it again,i get very little scrap.frickn' fustrating....
Mahalo for the tip.i will try your formulation and see what happens
Good job
there is a part 2, that includes the shark jaw bone braid. another tip to remember is: the looser the braid, the more you use
*****
i'll check it out
thank you
Well I tried your formula and they came up short ! I had to fuse on more cord too. I followed your formulas exactly. I have a 7.75" wrist and the bracelet says 8.25 " bracelet. What went wrong. I did the Oak Spike Sinnet and the Tire Tread Braid . ??????
triumphmanful hmm. the looser the tying the more cord you use. try adding 1" to the formula and see what that does.
i just tried your formula for the oak spike sinnet, 2ndary color formula is off. the secondary color ends too early and i couldn't finish the bracelet. didn't get to see if the primary color is correct, as i didn't get to finish. just thought i'd let you know.
same thing happened to me ! Formulas suck !
Do you have these formulas in a text file somewhere?
I do have them written down in a Word file, check out /watch?v=LWc0KtQQMPs. to see what I mean. and that has a place to request a file
How much cord do I need if my wrist is 71/2"
How much cord do i need
Mr. Bowfinger, could you please, please, PRETTY please give a formula for the Zawbar bracelet. I have made two and have had JUST enough to finish it off, I had to improvise because I didn't have enough to finish it as it was on the tutorial. Your formulas have been perfect for me so far, I hate having a lot of scrap but not as much as I hate not having enough cord to finish. If you can do that I would really appreciate the help
Hello, Angiedj62. Thanks for watching. I'm not familiar with the "Zawbar" braid.
Perhaps you can send me a link to it,if it's on you tube. I think after the holidays are over, I'll try to make a video explaining how I come up with these formulas. thanks again, and have a joyous holiday season.
*****
Thanks for replying, hope this will show you the Zawbar. I couldn't post a ling but under Youtobe just enter "Zawbar" in the search field. It was done byParacord 101. Thanks for your help.
Thank you sooooooo much
But just so you know, 4.5 X Y + Y is the same as 5.5 X Y
Hayden Fuller yup! you're right, I'll try to amend that. thanks
you know, I've never real done one, but, you might be the second pass will be thicker. So the per inch # will be off, so if you do it just doubled, you'll be short.
Do the 1st pass as normal, but then add a second formula to it, but doubled the per inch. Like so. Y=10"
=sum(4.5* x Y+Y) would give you 55"
double that gives you 110"
=sum(4.5 x Y+Y) + sum(9 x Y) would give you 145"
this is just a theory,only gives a guess as how the core radius is multiplied,
add 24" then cut & measure the drop
Do you have a video that shows how to weave a "D" ring into a dog collar?
sorry, I don't, but when I made the cat & dog collars, (in caterpillar braid),
I just ran the secondary cords thru the 'D' ring then back into the braid. I hope that helps. Hmmm. watch this video,

And in the comments you can request a spreadsheet. and I'll send a picture of how I do it. thanks for watching
tumbling brass?
The one is them two Solomon that has 2 side by side
Drinking game: 1 shot for OK and 2 shots for ALRIGHT..
Get wasted!!!
Hi cat :)
fish tail braid and how do you calculate Y
Thanks for watching Diane, please watch part 2 of the paracord formulas
/watch?v=tHl6wiNkDWg.
"Y" is the length of the bracelet.
Example if doing a solomans bar for 8 inches-the formula would be
( 4.5" X 8" plus 8") = 44" PER color/strand.
They are wrong. Did a 7.5 cobra bracelet ,added 1 inch to it;so 8.5 x 4.5 inches = 76.5inches of cord. Made it 80 inches, and still came up an inch short on the bracelet!
Was it 80" per strand?, and was the braid loose?
2 color bracelet ; 80 inch total . You said 4.5 per inch of color. Braid was tight as could be.
D Eret umm, 4.5" per inch PER cord = 76.5 " each color/strand, or 153" one color/strand. sorry that you got confused.
D Eret have to take in consideration the thickness of the finished item.
It would be 4.5 x 8.5+8.5
You
i'm thinking your favourite colour is yellow
How about a formula for a King Cobra bracelet or a King Cobra dog collar.
I have one in theory, but not verified because I have not yet made the actual braid. to be verified, I first need to be able to make (3) attempts, and come within 3-5" of each other, without coming up short. if you wish to try- place this in an excel cell:
=SUM(4.5*C53+C53)+SUM(9*C53)
C53 being the cell number ( it can any cell # you make it to be) A1, B2, etc.
It's still in experiment phase. if you do try it, I would love to know the results, thanks.
How about cord lengths for 95 weight cord? Everybody uses 550, I need to figure out length for a solomon braid bracelet using 95 weight paracord. NOT braiding around a 550 strand like everyone else does, I hate that, actually braiding the bracelet.
Hmm, a good question, the diameters will be different and therefore the maths will be different. A good way to get a idea is to use a known length, say 48" make the braid. Measure the finished part. Subtract the the remaining running ends. With that measurement, subtract the finished length, then divide the finished length. IE: starting with 48" get a finished piece of 5" with no leftover. (48-5)/5= 8.6"
8.6 × 5 +5 = 48 inches
@@Bowfinger6383 yeah suppose I will have to experiment.
I didn't see anything asked about your oak spike sennet bracelet formula. All your others had main color (I.e. caterpillar feet braid) as 8.5"xY+Y=? And secondary color as 2.8xY+3 (loop)=?
But on the oak spike you have main color = 6.235"xY+3"=? And secondary color as 3.176"xY=?
It's backwards from what your other formulas are and there's no "+Y" at the end of the 2nd color formula. Is the way you currently have in the video correct or is something missing?
Thank you beyond all words for these videos because I'm on disability and don't sell my stuff so I end up paying for the cord and while I don't mind that as it's my hobby, it does make me sick when a video says "5' of each color used" when all you really needed was 3-4' so I wasted 1-1.5' of cord which is fine if I'm making paracord buddies but I don't do many of those and I'd rather have all those scraps in 1 long piece for more bracelets.
So your video is a game changer for me. Thanks for doing these videos from all of us on a limited budget and all the people who can't stand waste :)
Thanks for watching BanjoDoje. as per the " Oat spike sinnet" you are correct in ,that there is no (+Y) in that formula,because as you make this braid,it has no core strand to braid around,
I.E: solomans bar has 2 core strands ( that is the (+Y) part.
The primary color in this video is the yellow, since it is the predominate color and uses more then the black. the (+3) that is in the formula is that little loop that gets "cow-hitched" to the buckle at the beginning. be mindful, however, that while this formulas works really good for me, your results may vary, ( the tighter you make the braid-the less you use & vice versa). I would recommending adding at least 1 foot to the total length of each color when first doing it. so that you will be able to finish. thanks again, and have a great time braiding.
*****
Ahhhh, ok, thanks for explaining that! That answers a lot of questions that I'd had in regards to amount of cordage and why some took what seemed to be way less than what I thought it should. That's why. No core strand! Well, that cleared that up - I learned something today so I should be able to sleep tonight :) Thanks.
I am making a pair of 8 foot reins. I did the math and got 144 feet. Does that sound correct?
4.5(96+96)+4.5(96+96)
4.5(192)+4.5(192)
864+864
1728in = 144 feet
I think it should be 4.5(96)+96 + 4.5(96)+96 = 528 + 528 = 1056 in. = 88 ft.
Kathryn Jones 100ft sounds close. All about trial and error on your first project. That said I'm sure you've figured out the correct formula by now.
WTF
I'm not a math wiz
I need it explained in voice, please
TheJollyHellHound that sucks! Life is all about numbers and common sense.
can you figure out the double cobra
