The Row Size Numbers Decoded: Margaux 10, 12, 15 and Beyond
At most luxury houses the sizes come labelled with adjectives. You are offered a Mini, a Small, a Medium and, when the house is feeling expansive, a Jumbo, and not one of those words commits to anything 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. Whatever number turns up in a model name is the bag’s width in inches. Margaux 10 comes in at ten inches across. Margaux 12 is twelve. That single fact carries more practical value than any amount of styling copy, and it is the through-line of this explainer.
The convention reaches well beyond the flagship. The full list runs 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 are the giveaway: nobody writes 15.75 unless the figure is meant to be read literally. What follows is how far the rule goes, 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, stated plainly
Take the number in the name, add the word inches, and you have the width of the bag. That is the system in full, applied consistently enough across the numbered families that it is sensible to treat as a rule rather than a coincidence. It is unusually honest labelling, because it erases the gap between what a size sounds like and what it measures. A Small at one house can be bigger than a Medium at another, yet ten inches is saint laurent ten inches anywhere. For anyone measuring The Row bags against something already in the wardrobe, it turns the comparison into arithmetic rather than guessing. That is also why the brand can offer four sizes of one silhouette and confuse nobody.
| Model | The size number, as width | Dimensions as published (W x 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 | Width from the name; measurements not listed |
| Margaux Shoulder 12 | 12 in per the name | 14.75 x 9 x 5 in, which is the exception to the rule |
| Margaux 17 | 17 in | Given approximately as 17 x 12 x 9 in |
| India 10.00 | 10 in | Not published officially |
| India 12.00 | 12 in | No official figures published |
| India 15.75 | 15.75 in | No official figures published |
| Agnes 12 | 12 in | Width from the name only |
| Agnes 15 | 15 in | Width from the name only |
| Marlo 12 | 12 in | Width by name only |
| Marlo 14 | 14 in | Width from the name only |

| Sofia 10 | 10 in | Archive model, not officially listed |
What the number leaves out
One dimension of three is width, and the remaining two do not scale with it in any predictable way. Place the two Soft Margaux sizes with official figures behind them side by side: 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 no proportional enlargement of the smaller one. Height is what shifts, by two inches, and width moves with it by the same. In practice, stepping up a size delivers a taller opening and more length rather than a deeper bag. Anyone expecting the 12 to swallow twice as much as the 10 will find the difference narrower than the numbers imply.
The handle drop is constant as well, at five inches on both Soft Margaux sizes, and that is another thing the model number never tells you. Five inches gives you a hand-carry or crook-of-the-elbow drop and not a shoulder one, which is precisely why both sizes ship with a removable shoulder strap. Interior fittings differ between them as well: the 10 has a single card slot while the 12 adds a second plus a zip pocket. Day to day, details like those count for more than an inch of width. Use the number to place the bag on a scale, then read the specification to make sense of it.
The one that bends the rule: the Margaux Shoulder 12
One current model breaks the pattern and it is worth spelling out rather than quietly. The Margaux Shoulder 12 carries a twelve in its name, but the brand lists its dimensions as 14.75 x 9 x 5 in. The width in the name and the width in the specification disagree, so the number is functioning as a family size rather than as a literal external measurement on this one. 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. Where a listing gives no dimensions at all, treat the number as a pointer rather than a measurement.
What each width holds in practice
The step most guides miss is translating inches into daily use. A bag under ten inches wide is a phone, cardholder, keys and lipstick proposition, which is the territory of the Sofia 8.75 and of the small clutches. At ten inches you have the textbook small day bag, taking a compact wallet, a phone, sunglasses and a slim pouch without distortion. Twelve inches is the point where a bag starts taking in a paperback, a small notebook, a folded scarf and a full-size wallet at once. A working width is fourteen to fifteen inches, the point at which documents and a tablet no longer have to be forced. Seventeen inches, as on the Margaux 17, reads as a travel dimension 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 overnight use, where soft structure counts as a feature rather than a compromise.
Price follows width, though material moves faster
Size and price move together, though not as sharply as you might expect. Take 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 much larger step for the same two inches. Material makes larger jumps than size does: 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, so the leather Agnes 15 costs only $600 more for three additional inches. If you are optimising spend, the material is the bigger financial decision and the width is the bigger practical one.
The bags that carry no size number
Much of the line sits outside this system, and it is the mixing of the two conventions that starts the confusion. The Park Tote family works in words rather than inches, running Small, Medium, Large and XL alongside the N/S Park Tote and Park Tote Three. The 90’s Bag, the Half Moon and the Bourse Clutch are small bags named without any size marker. With those, dimensions are all you have: the Bourse Clutch is listed at 10.2 x 6.5 x 2.3 in, and the Half Moon is given officially as 8 x 13.5 x 2.5 in, with other listings differing enough that the figure is best read as approximate. No rule governs the archive models either, the Camden measuring roughly 9 x 12.5 x 5.25 in despite carrying no number. The N/S and E/W prefixes are shorthand for orientation, as a rule read as north-south for taller shapes and east-west for wider ones.
How to turn inches into a decision
The practical value of a literal sizing system is that you can try it before you buy. Take a bag you already own and like, measure it, and set its width against the number in the model name you are considering. Do the same for the widest thing you routinely carry, whether that is a laptop, a folder or a water bottle, and add an inch of tolerance for soft construction. 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. When you are between sizes on a soft silhouette, the smaller one tends to look better and the larger one tends to work better. The actual choice in front of you is that trade-off and not the number itself, whenever you buy row handbags in a numbered family.
