Saint Laurent Niki
slouchy quilted flap bag with a leather-interwoven chain strap
In short
The Saint Laurent Niki Medium is published at 28 x 20 x 8.5 cm: a slouchy, crinkled-leather shoulder bag with a chain-through-leather strap that can be doubled or worn long. The 8.5 cm depth sits between the flat YSL flaps and the padded LouLou, and the 28 cm width makes it a full-size shoulder bag rather than a crossbody. This page keeps that figure and everything it is compared against.

Published size references (checked against the pages listed below)
Values here are published references for the model. Anything we could not verify on an open page is left as “not published yet” on purpose — we do not fill gaps with guesses.
Specifications in cm and inches
Every figure below has a record behind it on this site. Where the record has no value (interior and opening measurements are rarely published), the row says so instead of carrying a guess.

How this size sits in the range
The rows below are the nearest published sizes on this site to the Niki, measured the same way (width, height, depth). They are here so a 25 cm body can be judged against a 24 cm and a 28 cm one instead of against a number alone.
| Reference | Width | Height | Depth | What fits at that size | Where the figure comes from |
|---|---|---|---|---|---|
| Niki (this page) | 28 cm / 11.0 in | 20 cm / 7.9 in | 8.5 cm / 3.3 in | Phone, wallet, keys, sunglasses and a pouch in a slouchy body. | config/model-reference.json · ysl-niki-medium |

| Loewe Puzzle | 29 cm / 11.4 in | 19 cm / 7.5 in | 14 cm / 5.5 in | A 13-inch tablet, a wallet, keys and a pouch; the geometric body folds flat when half empty. | config/model-reference.json · loewe-puzzle |
| Bottega Veneta Jodie | 28 cm / 11.0 in | 23 cm / 9.1 in | 8 cm / 3.1 in | A full daily load with an 18 cm handle drop — the tier most buyers mean by "a Jodie". | bv-jodie-bag-size-guide (this site) |
| Louis Vuitton Capucines BB | 27 cm / 10.6 in | 17.3 cm / 6.8 in | 9 cm / 3.5 in | A structured daily bag: phone, wallet, keys, sunglasses and a compact, kept to 9 cm of depth. | config/model-reference.json · lv-capucines-bb |

| Dior Saddle | 25.5 cm / 10.0 in | 20 cm / 7.9 in | 6.5 cm / 2.6 in | Phone, cardholder, keys and sunglasses in a flat saddle body; a wallet starts to strain the 6.5 cm depth. | config/model-reference.json · dior-saddle-medium |
Comparisons use published outside measurements. Two bags of the same width can hold different amounts, because depth and body rigidity decide more than width does.

Every centimetre above is printed in this site’s own records; inch values are the same figures converted at 2.54 cm per inch and rounded to one decimal, so no page carries a second set of inches. Rows marked as reference points are neighbouring models published on this site, not Niki tiers — they are here to give the ladder a scale.
The same figures are indexed, with the source page and the date each one was checked, in the Luxury Bag Size Index — the cross-brand table that holds the published centimetre figures for bags, belts and shoes in one place.
Dimensions in cm and inches
One published figure for the Niki Medium, with the two YSL lines either side of it quoted for scale.
The Niki Medium is published at 28 x 20 x 8.5 cm, which is 11 x 7.9 x 3.3 inches. The Niki sits between two Saint Laurent ideas: flatter than the LouLou, which is published at 32 x 22 x 12 cm at its Medium tier, and much roomier than the Envelope at 24 x 18 x 6 cm. The 28 cm width is the figure that makes it a shoulder bag rather than a crossbody — it reads as a full-size bag on most frames.
The leather is crushed rather than smooth, so the published figures describe the body at rest. A Niki loaded for a working day spreads by a centimetre or so at the base, which is normal for a soft body and is exactly why photograph-based sizing is unreliable for this model.
Inch values are the published centimetres converted at 2.54 cm per inch and rounded to one decimal, the same rule the guides use. Rows with no published figure say so.
How to recognise it in a photo
Crinkled, lived-in leather with large diamond quilting, a leather-interwoven chain and a metal YSL on the front.
Not this style when: A crisp body with an all-metal chain is not a Niki.
The Niki is identified by its surface and its strap rather than by hard hardware.
- Shape and closure: Crinkled, lived-in leather with large diamond quilting, a leather-interwoven chain and a metal YSL on the front.
- Not this model when: A crisp body with an all-metal chain is not a Niki.
- Hardware: the record lists silver; the clasp or turn-lock should match that finish in the photos.
- Materials: crinkled lambskin on the record — grain and sheen in the photo should look consistent with those.
- Size in frame: the model record publishes 28 x 20 x 8.5 cm, so a photograph with a phone or a tape beside the bag is the only way to check the tier.
- Strap and hardware: ask for the strap or handle laid straight, so the drop can be read rather than estimated from a worn photograph.
- Look at the strap: the chain runs through leather rather than bare, and the leather itself should show the crushed, irregular grain the Niki is published with.
What fits inside
A full personal-items load at 28 x 20 x 8.5 cm, and where the soft body starts to sag.
A full wallet, a phone, keys, sunglasses in a soft pouch and a compact fit together with the bag still sitting flat against the body. A slim tablet fits in the 28 cm width, and a folded scarf or light jumper is realistic in the 8.5 cm gusset if the hard items stay minimal.
What it will not do cleanly is documents. An A4 folder has to bend, and a laptop stands above the rim, so the Niki is a day bag for personal items rather than a work bag — the OnTheGo or a tote is the answer for a folder.
- Phone, wallet, keys, sunglasses and a pouch in a slouchy body.
- A full wallet, a phone, keys, sunglasses and a compact fit without the bag being full.
- A slim tablet fits at the 28 cm width; a hard case alongside it begins to pull the base.
- An A4 folder or a laptop does not belong in this body — a tote is the correct answer.
These capacity notes are read off the published outside dimensions and the tier ladder, not from a measured interior: the site has no published interior figure for this model, so treat them as a size guide rather than a packing list.
No interior figure is published for the Niki, so these notes are read from the 28 x 20 x 8.5 cm outside dimensions.
How it compares with the next size up
Three published Saint Laurent sizes sit within 4 cm of the Niki Medium in width.
Against the Envelope Medium at 24 x 18 x 6 cm, the Niki Medium is 4 cm wider, 2 cm taller and 2.5 cm deeper — enough to move from cards-and-phone to a full wallet and a compact. Against the LouLou Small at 25 x 17 x 9 cm, the Niki is 3 cm wider and half a centimetre shallower, so the two carry similar loads in different bodies, padded against crushed.
One tier up within the wider Saint Laurent range is the LouLou Classic Medium at 32 x 22 x 12 cm, which adds 4 cm of width and 3.5 cm of depth. That is the step where a slim laptop starts to be arguable. Below the Niki, the Jamie Small at 25 x 15 x 7.5 cm is the compact tier of the same flat-quilted family.

- The crushed leather grain is the identifying feature in photographs, and the quilted Y-chevron stitching should follow the curve of the flap rather than run straight.

Questions buyers ask about the Saint Laurent Niki
What are the published dimensions of the Saint Laurent Niki?
The model record publishes Saint Laurent Niki at 28 x 20 x 8.5 cm, which is 11.0 x 7.9 x 3.3 inches at 2.54 cm per inch. Width, height and depth are the three figures in that order, measured outside the body. The Niki is published as Baby, Medium and Large; this site publishes the Medium 28 × 20 × 8.5 cm figure.
What fits inside the Saint Laurent Niki?
Phone, wallet, keys, sunglasses and a pouch in a slouchy body. That reading is derived from the published outside dimensions and the size's position in the range — it is an estimate of capacity, not a measured interior, because no interior figure is published for this model.
Which other sizes does the Niki come in?
This site can source one published size for the Niki: 28 x 20 x 8.5 cm. Rows marked as reference points in the ladder table are neighbouring models, not Niki tiers.
Does the Niki Medium hold a laptop?
No. At 28 x 20 x 8.5 cm a slim tablet fits, but a laptop stands above the rim and the soft body will not hold its shape around one. The published figures for this tier describe a personal-items shoulder bag; a folder or a laptop belongs in a structured tote such as the OnTheGo MM.
How does the Niki compare with the Envelope?
Both are Saint Laurent flaps with a chain. The Envelope Medium is published at 24 x 18 x 6 cm and the Niki Medium at 28 x 20 x 8.5 cm, so the Niki is 4 cm wider, 2 cm taller and 2.5 cm deeper. The practical difference is that the Niki takes a full wallet and a compact together and the Envelope does not.
Where do the numbers on this page come from?
Sizes come from the model record for Saint Laurent Niki and from this site's own guides, listed row by row in the ladder table and in the sources table at the end of the page. Nothing here is averaged: where two published values disagree, both are printed.
Model references that sit next to this one
These pages use the same published-specification format, so a size, a strap drop or a depth can be compared without leaving the site.
