The Row Size Numbers Explained: Margaux 10, 12, 15 and Beyond
Adjectives are how most luxury houses name their sizes. A Mini, a Small, a Medium and, if the house is feeling expansive, a Jumbo: and none of them means anything you can measure. The Row does something quietly different across a large part of its line, and once you notice it the whole catalogue becomes far simpler to read. Whatever number sits 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 does more practical work than any amount of styling copy, and it is the spine of this explainer.
The convention reaches well beyond the flagship. The roll call 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 literally. What follows is how far the rule extends, 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
The number in the name plus the word inches gives you the width of the bag. That is the entire system, and it is applied consistently enough across the numbered families to be treated as a rule rather than a fluke. It is unusually honest labelling, since it closes the gap between what a size sounds like and what it measures. One house’s Small can beat another house’s Medium, but ten inches is ten inches anywhere. For anyone measuring The Row bags against something already in the wardrobe, it turns the comparison into arithmetic rather than guessing. It also explains how the brand can run four sizes of a single silhouette without confusing anyone.

What the number misses
One dimension of three is width, and the remaining two do not scale with it in any predictable way. Set 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 not a scaled copy of the smaller one. The height changes, gaining two inches, and so does the width, by the same amount. In practice that means stepping up a size gives you a higher 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 slighter 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 will not tell you. Five inches is a hand-carry or crook-of-the-elbow drop rather than a shoulder drop, and both sizes come with a removable shoulder strap to make up the difference. Fittings inside differ too: a single card slot on the 10, while the 12 adds a second plus a zip pocket. Those details settle how a bag behaves day to day far more than an inch of width does. Read the number to place the bag on a scale, then read the specification to understand it.
The Margaux Shoulder 12, and where the rule bends
A single current model breaks the pattern, and it deserves to be said out loud rather than quietly. The Margaux Shoulder 12 has a twelve in its name, yet the brand lists its dimensions as 14.75 x 9 x 5 in. Because the width in the name and the width in the specification disagree, the number is doing the job of a family size rather than 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 straightforward scaling of the tote. So generalise the lesson, and use the number as a starting point before confirming against published dimensions and committing. Where a listing carries no dimensions at all, read the number as a signal rather than a measurement.
What each width will actually carry
Turning inches into daily use is the step most guides pass over. A bag under ten inches wide is a phone, cardholder, keys and lipstick affair, which is the territory of the Sofia 8.75 and of the small clutches. Ten inches is the classic small day bag, good for a compact wallet, a phone, sunglasses and a slim pouch without distortion. At twelve inches a bag begins absorbing 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 are no longer a squeeze. Seventeen inches, as on the Margaux 17, reads as a weekend and travel dimension rather than an everyday one.
- 8.75 to 10 in: evening, errands and anything where you want the bag to disappear.
- 12 in: the most versatile width on offer and the one most buyers end up choosing.
- 14 to 15 in: work, commuting and days when you carry other people’s things too.
- 17 in: travel and staying over, where soft structure is a feature and not a compromise.
Width lifts the price, but material moves faster
The two track each other, size and price, though less steeply than you might assume. On observed 2026 market prices, the Soft Margaux 10 sits at $3,650 and the Soft Margaux 12 at $4,350, which puts two inches of width at about $700. Marlo 12 has been observed at $3,600 and $4,900 depending on the version, with Marlo 14 at $5,300, a far bigger step for the same two inches. Material makes bigger 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, meaning 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. 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 like the 90’s Bag, the Half Moon and the Bourse Clutch carry no 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 best read as approximate. Archive models follow no rule either, with the Camden measuring roughly 9 x 12.5 x 5.25 in despite carrying no number. Orientation shorthand is what the N/S and E/W prefixes provide, broadly read as north-south for taller shapes and east-west for wider ones.
Making the decision from the inches
The practical value of a literal sizing system is that it can be verified 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 with the widest thing you routinely carry, be it a laptop, a folder or a water bottle, and add an inch of tolerance for soft sides. Keep in mind that most of these are unstructured shapes, which is why a bag looks smaller empty and fuller in use than any flat measurement implies. When you are between sizes on a soft silhouette, the smaller one tends to look better and the larger one tends to perform better. That trade-off, rather than the number itself, is the genuine choice in front of you when you buy row handbags in a numbered family.
