What length shibari rope to use

Buy 8 m. It is one of the two standard Western lengths and it is what we cut to. The other is 7.5 m, and either works as a first rope.

Japanese rope is usually 7 m. We will cut that too, on request.

At a glance

Length	Where you see it	What it suits
2 m	Quarter-length or baby rope	A small extension when a tie is nearly finished
4 m	Half-length	Extending a tie without adding a full rope
7 m	The Japanese convention	Classical kinbaku
7.5 m	Common in UK and EU shops	Half a metre under 8 m, ties the same patterns
8 m (about 26 ft)	Standard in Western shops, and our default	Two-rope ties, chest harnesses, almost everything an introduction class teaches
10 m	Specialty	Suspension uplines
12 m	Specialty	Long uplines

Folded length

Rope is worked doubled for most shibari. Fold an 8 m rope at its midpoint and you have two working legs of about 4 m each. That is the length you are handling, even though the label says 8 m.

Shops and class equipment lists give the full end-to-end length. If a class asks for a 4 m rope, assume it means an actual 4 m rope, because lists routinely ask for a mix, “one 4 m and one 8 m” being a common pattern. If a sheet is ambiguous, ask the teacher before you buy. All lengths on this page are end-to-end.

Why we cut to 8 m

7.5 m and 8 m are where most of the Western market sits. Shibari Notes calls 6 mm at 8 m the most common choice. Anatomie in London sells its treated jute at 7.5 m and 15 m, and its own beginner guidance puts most jute sold at 7.5 m. Both numbers are normal.

We cut to 8 m because it is the length an introduction class in the Benelux is most likely to assume, and because the extra half metre leaves more working end when a tie is finished. Check your class equipment list before you buy, though. Some teachers work at 7.5 m and some ask for a separate short rope.

Where to buy other lengths

If you want a wider off-the-shelf range than we carry, buy from someone else. That is a shorter list than it looks.

• Anatomie, London, sells treated jute at 7.5 m and 15 m. If a 15 m rope is what you want, buy from them.
• TheRopestry has the clearest cut-length catalogue, 4 m through 16 m, including dedicated upline lengths.
• AMATSUNAWA sells jute on rolls, roughly 90 m to 450 m, plus 4 m samples. That is the right purchase if you intend to cut and finish your own rope. It is the wrong one if you want rope you can tie with on arrival.

The full shop list, with what each is best for, is in our guide to buying rope in the Benelux.

The 7 m question

Japanese rope is usually cut to 7 m, though nowadays it varies and 8 m is common there too. Several European shops settled on 7.5 m. There is no well-sourced history for either number.

A practical explanation is reach. Some people measure rope to roughly four of their own arm spans, or four full pulls from hand to hand. That tends to land near 7 m and keeps a doubled rope manageable. It is a useful way to choose your own rope length.

The origin stories are less clear. One says 7 m is roughly the perimeter of two standard tatami mats laid side by side. Another links the length to the tan, a traditional cloth bolt. The second explanation does not survive the measurements: kimono cloth was measured with the longer kujirajaku, and documented bolts ran roughly 9.9 to 10.6 m historically and sit around 12.5 m today. Nowhere near 7.5 m.

We have even been told that 7 m came from the length of rope sold at Japanese post offices. We could not find that story in print or online, let alone verify it. Treat it as rope folklore.

If you learned at 7 m, or you want the classical length, write to us and we will cut 7 m lengths from the same stock as the 8 m rope. Same rope, same finish, shorter length.

Length and the body you are tying

You use more rope on a larger person and less on a smaller one to tie the same pattern.

The practical effect is at the end of a tie, in how much working end you have left. A chest harness on a larger frame can consume most of an 8 m rope, where the same harness on a smaller frame leaves you a comfortable tail. If you are new, 8 m is fine for whoever you are tying. Once you have some experience you may start tailoring: longer when you keep running out, shorter when you keep managing an awkward tail.

How many ropes a tie takes

The number depends on the tie and on the person. A thigh tie takes one 8 m rope, sometimes two. A chest harness is commonly two, sometimes three. More rope buys flexibility, not correctness.

Two 8 m ropes is the working minimum. Three is what we recommend, and what the kit ships, because the third rope is what lets you extend a pattern instead of untying to reuse the first. The full first-purchase question is in what to buy for your first class.

Half and quarter lengths

Short ropes are often called baby ropes. With an 8 m standard, a half-length is 4 m and a quarter-length is 2 m.

They are useful when a tie is nearly finished and you need a little more rope. Adding 2 m or 4 m avoids pulling through a full 8 m rope and then managing the excess.

A useful addition to an established rope bag is two half-lengths and one quarter-length. They supplement the full-length ropes rather than replacing the two or three full ropes in a first kit.

When you need something longer

Uplines are the usual reason to go past 8 m. EU shops sell them at 10, 12, 15 and 16 m, and the length you need depends on the height of the hard point and how the line is routed. Ask your instructor before ordering rather than picking a number off a table.

We do not stock long lengths. We will cut 10 m or 12 m from the same Ogawa or POSH stock as the standard 8 m rope. Allow a few extra days, because it is made to order.

Long rope is not a first-kit purchase. The ties most beginners learn are 8 m ties.

What we ship, and what we cut

We stock 8 m lengths in both fibres: 6 mm Ogawa jute and 5 mm POSH, hand-finished in Leuven and dispatched in two working days.

Write to us before you order for anything else:

• Baby ropes at 2 m or 4 m.
• Other shorter lengths from 5 to 7 m, including the classical 7 m.
• Longer, 10 to 12 m.
• A set with more than one length in it, if you tell us the mix by email before ordering.

The material, diameter and finish stay the same at every length. What changes is how much pull-through a tie needs and how much tail you are left managing. Allow a few extra days on any non-default length.

A working set after a year or two often looks like several 8 m ropes for body work, one or two longer ropes for uplines, and a few baby ropes for extensions and detail. Nobody buys that on day one. Add to it when a tie you keep wanting shows you what is missing.

Diameter is covered in rope thickness and the fibre choice in POSH vs jute.
