The Row Size Numbers Made Simple: Margaux 10, 12, 15 and Beyond

Most luxury houses size their bags with adjectives. You get a Mini, a Small, a Medium and, if the house is feeling expansive, a Jumbo, and none of those words commits to a single thing you can measure. The Row takes a quietly different route across a large part of its line, and noticing it makes the whole catalogue easier to read. The number sitting in a model name is the bag’s width in inches. Margaux 10 comes in at ten inches across. Margaux 12 comes in at twelve. That single fact is worth more in practice than any amount of styling copy, and it is the backbone of this explainer.
The convention reaches well beyond the flagship. It includes Margaux 10, 12, 15 and 17, India 10.00, 12.00 and 15.75, Agnes 12 and 15, Sofia 8.75 and 10, and Marlo 12 and 14. The decimals give it away, because nobody writes 15.75 unless the figure is meant to be read literally. Below: how far the rule holds, where it bends, what the number leaves out, and how to turn it into a decision when you are choosing between two sizes of the same bag.
The rule in plain terms
Read the number in the name, add the word inches, and that is the width of the bag. That is the whole system, and it holds consistently enough across the numbered families to count as a rule rather than a accident. The labelling is unusually honest, because the gap between what a size sounds like and what it measures simply closes. One house’s Small can outsize another house’s Medium, but ten inches is ten inches anywhere. If you are comparing The Row bags with something you already own, the comparison becomes arithmetic rather than instinct. It also explains why the brand can run four sizes of one silhouette without muddling anybody.
| Bag | Size number read as width | Published dimensions (W x ysl H x D) |
|---|---|---|
| Soft Margaux 10 | 10 in | 10 x 7 x 7.5 in |
| Soft Margaux 12 | 12 in | 12 x 9 x 7.5 in |
| Soft Margaux 15 | 15 in | Name gives the width; measurements not listed |
| Margaux Shoulder 12 | 12 in by name | 14.75 x 9 x 5 in, the exception to the rule |
| Margaux 17 | 17 in | Approximately 17 x 12 x 9 in |
| India 10.00 | 10 in | Not officially published |
| India 12.00 | 12 in | No official figures published |
| India 15.75 | 15.75 in | Not officially published |
| Agnes 12 | 12 in | Only the width, taken from the name |
| Agnes 15 | 15 in | Width by name only |
| Marlo 12 | 12 in | Only the width, taken from the name |
| Marlo 14 | 14 in | Width from the name; nothing further listed |
| Sofia 8.75 | 8.75 in | Archive piece; not listed officially |
| Sofia 10 | 10 in | Archive piece; not listed officially |
What the number leaves out
One dimension of three is width, and the remaining two do not scale with it in any predictable way. Set against each other the two Soft Margaux sizes with official figures behind them: the 10 measures 10 x 7 x 7.5 in and the 12 measures 12 x 9 x 7.5 in. Depth is identical at 7.5 inches, which means the larger bag is not a proportional enlargement of the smaller one. What actually changes is the height, up by two inches, and the width, up by the same. In practice, stepping up a size gets you a taller opening and more length rather than a deeper bag. If you expect the 12 to hold twice what the 10 holds, the difference will be smaller than the numbers imply.
The handle drop stays constant too, at five inches on both Soft Margaux sizes, which is another thing the model number keeps to itself. Five inches is a hand-carry or crook-of-the-elbow drop rather than a shoulder one, and both sizes ship with a removable shoulder strap to make up the difference. The interior fittings are different too, since the 10 has a single card slot while the 12 adds a second plus a zip pocket. Those details shape how a bag behaves day to day far more than an inch of width ever will. Use the number to place the bag on a scale, then read the specification to understand it.
The Margaux Shoulder 12, where the rule bends
One model in the current line departs from the pattern, and that is worth stating clearly rather than quietly. A twelve sits in the name of the Margaux Shoulder 12, but the brand lists its dimensions as 14.75 x 9 x 5 in. Name width and specification width part company here, so on this model the number serves as a family size rather than a literal external measurement. That is consistent with what the silhouette does, since it is a reworked shape with elongated tubular handles and narrowed gusseted side panels rather than a plain scaling-up of the tote. The lesson generalises, then, and use the number as a starting point before confirming against published dimensions and committing. If a listing offers no dimensions at all, the number is a pointer and not a measurement.
What each width actually holds
Most guides skip the step that matters, which is translating inches into daily use. Under ten inches wide you are looking at a phone, cardholder, keys and lipstick kit, which is where the Sofia 8.75 and the small clutches live. Ten inches is the classic small day bag, room enough for a compact wallet, a phone, sunglasses and a slim pouch without distortion. At twelve inches a bag begins swallowing a paperback, a small notebook, a folded scarf and a full-size wallet at once. Fourteen to fifteen inches is a working width, the point at which documents and a tablet stop being a squeeze. Seventeen inches, as on the Margaux 17, is a weekend and travel size rather than an everyday one.
- 8.75 to 10 in: evening use, errands and any occasion where you want the bag to vanish.
- 12 in: the line’s most versatile width and the one most buyers settle on.
- 14 to 15 in: work, the commute and days when you carry other people’s things as well.
- 17 in: travel and staying over, where soft structure is a feature and not a compromise.
Price climbs with width, but material moves faster
Price follows size, but not as steeply as you would expect. Using observed 2026 market prices, the Soft Margaux 10 sits at $3,650 and the Soft Margaux 12 at $4,350, so two inches of width costs about $700. Marlo 12 is observed at $3,600 and $4,900 depending on the version, and Marlo 14 at $5,300, a far bigger step for the same two inches. Material moves in bigger jumps than size does, since India 10.00 is $3,850 in leather against $5,370 in suede, and Agnes 15 runs $5,000 in leather, $5,800 in suede and $4,300 in a canvas blend. Agnes 12 sits at $4,400, meaning the leather Agnes 15 costs only $600 more for three additional inches. If you are optimising spend, choosing the material is the bigger financial decision, and choosing the width is the bigger practical one.
The models that carry no number
Plenty of the line falls outside the system, and confusion starts when the two conventions get mixed. Words rather than inches govern the Park Tote family, which runs Small, Medium, Large and XL alongside the N/S Park Tote and Park Tote Three. Small bags such as the 90’s Bag, the Half Moon and the Bourse Clutch are named without any size marker. For those, dimensions are the only guide: the Bourse Clutch is listed at 10.2 x 6.5 x 2.3 in, while the Half Moon is given officially as 8 x 13.5 x 2.5 in, with other listings differing enough that the figure is safest treated as approximate. Archive models follow no rule either, with the Camden measuring roughly 9 x 12.5 x 5.25 in despite bearing no number. The N/S and E/W prefixes are shorthand for orientation, typically read as north-south for taller shapes and east-west for wider ones.
How to turn inches into a decision
A literal sizing system earns its keep because you can test it before you buy. Measure a bag you already own and like, and compare its width against the number in the model name you are considering. Do the same with the widest thing you routinely carry, be it a laptop, a folder or a water bottle, and add an inch of tolerance for the soft sides. Remember that these are unstructured shapes in most cases, so a bag will look smaller when empty and fuller in use than any flat measurement suggests. If you are between sizes on a soft silhouette, the smaller one usually looks better and the larger one usually performs better. That trade-off, not the number itself, is the real choice in front of you when you buy row handbags in a numbered family.
