The Row Size Numbers Decoded: Margaux 10, 12, 15 and Beyond
At most luxury houses the sizes are named with adjectives. A Mini, a Small, a Medium and, if the house is feeling expansive, a Jumbo: none of those words commits to 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. The number in a model name is its width, in inches. Margaux 10 comes in at ten inches across. Margaux 12 comes in at twelve. That one fact does more practical work than any amount of styling copy, and it runs through this explainer throughout.
The system runs further than the flagship alone. 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. 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 torn between two sizes of the saint-bags.com/tote-bags same bag.
The rule in plain terms
Take the number in the name, append the word inches, and you have 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 coincidence. It is unusually honest labelling, because it erases the gap between what a size sounds like and what it measures. A Small from one house can be larger than a Medium from another, but ten inches is ten inches anywhere. For anyone comparing The Row bags to something already in their wardrobe, that makes the comparison arithmetic rather than guesswork. It also explains why the brand can run four sizes of one silhouette without muddling anybody.

What the number does not tell you
Width is one dimension of three, and the other two refuse to scale with it in any predictable way. Line up 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. The depth is identical at 7.5 inches, so the larger bag is not a proportional enlargement of the smaller one. Height is what moves, by two inches, and width moves with it by the same. In practice that means stepping up a size gives you a taller mouth and more length rather than a deeper bag. Anyone assuming the 12 will swallow twice as much as the 10 will find the difference 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 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 cover the rest. Interior fittings are different too: 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 understand it.
The Margaux Shoulder 12, where the rule bends
A single current model breaks the pattern, and it deserves to be said plainly 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. The width in the name and the width in the specification do not match, so the number is operating 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: treat the number as a starting point, then confirm against published dimensions before you commit. Where a listing gives no dimensions at all, treat the number as an indication rather than a measurement.
What each width really holds
Turning inches into daily use is the step most guides pass over. Anything under ten inches wide is a phone, cardholder, keys and lipstick affair, the domain of the Sofia 8.75 and 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. Twelve inches is the point where a bag begins absorbing 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 travel and weekend dimension rather than an everyday one.
- 8.75 to 10 in: evenings, errands and anything where the bag should disappear.
- 12 in: the most useful width in the line and the one most buyers settle on.
- 14 to 15 in: work, commuting and days when you carry other people’s things too.
- 17 in: travel and overnight use, where soft structure is a feature rather than a compromise.
Price climbs with width, but material moves faster
The two track each other, size and price, though less sharply than you might assume. 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 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. Larger jumps come from material than from size: India 10.00 is $3,850 in leather against $5,370 in suede, while Agnes 15 runs $5,000 in leather, $5,800 in suede and $4,300 in a canvas blend. With Agnes 12 at $4,400, the leather Agnes 15 is only $600 more for three additional inches. Where spend is being optimised, material is the bigger financial decision and width the bigger practical one.
The models that carry no number
A good deal of the line sits outside this system, and mixing the two conventions is where the confusion starts. The Park Tote family trades 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 at all. 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 treated as approximate. Archive models follow no rule either, and the Camden measures roughly 9 x 12.5 x 5.25 in despite bearing 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.
Turning inches into a choice
A literal sizing system proves itself because you can test it before you buy. Measure a bag you already own and like, and compare its width to the number in the model name you are considering. Repeat it for the widest thing you carry routinely, whether a laptop, a folder or a water bottle, then add an inch of tolerance for the soft sides. Bear in mind that these are unstructured shapes in most cases, so a bag looks smaller when empty and fuller in use than any flat measurement suggests. Caught between sizes on a soft silhouette, you will generally find the smaller one looks better and the larger one earns its place. That trade-off, rather than the number itself, is the real choice in front of you when you buy row handbags in a numbered family.
