TL;DR: A Japanese silk table runner cut from nothing — that is, a vintage obi used exactly as it was woven — is roughly 30 to 40cm wide and 3.5 to 4.5m long, heavy enough to lie flat without slipping, one of a kind, and priced from about $45 to several hundred dollars depending on fibre and era. A standard shop runner is shorter, lighter, washable, repeatable, and costs a fraction as much. The obi wins on presence and story. The standard runner wins on laundry. This page is the honest comparison, including the cases where you should buy the cheap one.
We sell the obi, so read the price and durability rows here with that in mind. We have tried to write the comparison we would want if we were choosing, which means naming the two situations where a standard runner is the right call.
What is the actual difference in size?#
This is the argument that decides most tables, and it is a difference of purpose, not of taste.
An obi is a sash. It has to wrap an adult torso two or three times and still leave enough length for an elaborate knot at the back, which is why the formal ones run 3.5 to 4.5m long. Width settles around 30 to 40cm because that is what sits comfortably between ribs and hips. Those two numbers happen to be very close to what a table runner wants, which is the whole reason this category exists. The champagne brocade piece in our shop measures 31 × 440cm; the silver one measures 30.5 × 440cm.
A retail table runner is designed against a different constraint: it is sold in fixed sizes to fit standard dining tables, so it comes in set lengths, most of them comfortably under three metres, with a hem at each end.
| | Vintage obi | Standard retail runner | |—|—|—| | Width | 30–40cm, set by the human body | Typically similar, set by the table | | Length | 3.5–4.5m, one length only | Fixed lengths, usually well under 3m; pick the one that fits | | Fit method | Fold or double back the excess | Buy the size | | Edges | Already finished; no cutting or hemming needed | Hemmed | | Weight | Substantial, especially brocade | Light | | Repeatable | Never — each piece is one of one | Yes, buy two |
The practical consequence: on a long table an obi runs the full length and still gives you a generous fall at each end. On a small table you fold it, and folding is not a compromise. A doubled obi is thicker, sits with more authority, and shows twice the pattern density at the centre. Our guide to styling an obi as a table runner works through the fold options for each table shape.
How differently do they drape?#
Pick up a mass-market runner and it flutters. Pick up a brocade obi and it falls.
Weight and weave do that. Formal obi are woven from pre-dyed silk yarns, often with metallic thread passages, into a dense cloth with relief in it. The fabric has body. Laid down a table it stays where you put it, does not creep when someone leans on it, and holds a fold cleanly at the table edge rather than curling. The trade-off is that it is not supple: an obi will not drape softly over a rounded edge the way a loose linen runner does. It behaves more like a flat panel than a cloth.
There is also the way it reads under light. Because the metallic passages are foil-wrapped thread rather than print, the pattern changes as you move around the table and as the light changes through the evening. That is the effect people are actually buying. It does not photograph well and it is obvious in the room.
Which one is better value?#
Depends entirely on what you are buying.
| | Vintage obi | Standard runner | |—|—|—| | Typical price | $45–65 polyester, $85–130 silk blend from the Showa era, $160–280 pure silk Meiji or Taisho | A small fraction of that | | Cost per year | High up front, decades of life if kept out of sun and stored rolled | Low up front, replaced when it stains | | Washing | Spot clean only | Machine wash | | Uniqueness | One of one; there is no restock | Buy the matching napkins | | Resale | Vintage textiles hold value; a graded, documented piece holds more | None | | Delivery | Shipped from Japan, 5–14 days by EMS in our case | Two days from a warehouse |
Two cases where the standard runner is simply the right purchase, and we would rather say so:
- A table with small children eating at it every day. Spot-clean-only is a real constraint. Yoghurt is not a spot.
- You want a pair, or a set that matches the napkins. One of one means one. If the scheme depends on symmetry across two tables, we cannot supply it and a retail range can.
And the case where the obi is not just nicer but cheaper than the alternative: when what you actually want is a piece of textile art. Compare it against a framed print rather than against a runner and the arithmetic looks different, especially since the same object can move to a wall. Our obi wall hanging guide covers that mount.
What about the things that look like flaws?#
Two of them come up constantly, and both are normal.
Fold lines. Vintage obi were stored folded, for decades, so most arrive with soft creases across the width. They are not damage and they relax with use or gentle steam held away from the cloth. We say so on the listing rather than photographing around them.
Silk that is not silk. Plenty of vintage obi are polyester, especially anything from the 1970s onward, and a polyester obi is an honest vintage garment that should cost less. The problem in this market is listings that say “silk” and mean nothing by it. Learn the four tests in our guide to telling silk from polyester before you spend at the top of anyone’s range, ours included.
How do you choose between them? A short checklist#
Run down this list and the answer usually declares itself.
- How long is the table? Over 2m of runnable length, the obi is the only one of the two that covers it in a single piece.
- Who eats at it, and how often? Daily family meals with small children point to washable. Dinner parties and a mostly decorative table point to the obi.
- Do you need more than one? More than one means retail.
- Do you want it to be interesting, or to disappear? A brocade obi is a focal point. If the scheme needs the table to stay quiet, a plain linen runner does that job better and for less.
- Will it sit in direct sunlight? If yes and you cannot move it, do not buy silk of any kind. Light fades dye and weakens the fibre, and the damage is permanent. Our care guide explains what to do instead.
- Are you buying an object or a story? A vintage obi comes with an era, a weave, a motif vocabulary and a reason someone commissioned it. If none of that matters to you, you are paying for something you will not use.
What you are actually paying for#
The price gap between a $20 runner and a $130 obi is not a materials markup. It is the fact that somebody stood in a market in Japan, handled the piece, checked the reverse for moth holes and hidden staining under the folds, dated it, graded the fibre, measured it, and wrote down what is wrong with it as well as what is right. That work is why two pieces that look similar in a photograph can be worth $45 and $280, and it is the work a mass-market supply chain does not do because it does not need to.
If you want the whole picture before choosing, our complete guide to vintage obi as home decor covers types, eras and rooms, and the motifs woven into the piece have meanings worth knowing, which we unpack in what the motifs on your obi mean. Every obi in the KINU Tokyo shop is listed with its fabric, era, exact dimensions and condition, and each one is one of one.
