The Row Size Numbers Made Simple: Margaux 10, 12, 15 and Beyond
Adjectives are how most luxury houses handle sizing. You get a Mini, a Small, a Medium and, if the house is feeling expansive, a Jumbo, and none of those words amounts 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 measures ten inches across. Margaux 12 is twelve inches. That single fact does more real work than any amount of styling copy, and it is the through-line of this explainer.
The system runs further than the flagship alone. It reaches across 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 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, put plainly
Take the number buy online in the name, add the word inches, and you have the bag’s width. That is the whole system, and it holds consistently enough across the numbered families to count as a rule rather than a fluke. It is unusually plain labelling, since it closes the gap between what a size sounds like and what it measures. A Small from one house can be bigger than a Medium from another, 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 approximation. It also explains how the brand can run four sizes of a single silhouette without creating confusion.

What the number does not tell you
Width is one dimension of three, and the other two will not scale with it in any predictable way. Put 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. The depth stays identical at 7.5 inches, so the bigger bag is no proportional enlargement of the smaller one. What really changes is the height, up by two inches, and the width, up by the same. What that means in use is that a size up adds a taller opening and more length rather than extra depth. Anyone expecting the 12 to swallow twice as much as the 10 will find the difference narrower than the numbers imply.
Handle drop holds steady too, at five inches on both Soft Margaux sizes, one more detail the model number leaves unsaid. Five inches gives you a hand-carry or crook-of-the-elbow drop and not a shoulder one, which is why both sizes ship with a removable shoulder strap. Interior fittings differ 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 matter more than an inch of width. Read the number to place the bag on a scale, then read the specification to know how it behaves.
The Margaux Shoulder 12, where the rule bends
One current model breaks the pattern and it is worth saying clearly rather than quietly. The Margaux Shoulder 12 has a twelve in its name, yet the brand publishes 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 fits what the silhouette actually does, because it is a reworked shape with elongated tubular handles and narrowed gusseted side panels rather than a simple scaling of the tote. The lesson carries over: use the number as your starting point, then confirm against published dimensions before you commit. Where a listing gives no dimensions at all, treat the number as a guide rather than a measurement.
What each width actually holds
Translating inches into daily use is the step most guides miss out. 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 belong. Ten inches is the classic small day bag, enough for 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 together. Fourteen to fifteen inches is a working width, where documents and a tablet stop needing to be forced. Seventeen inches, as on the Margaux 17, is a weekend and travel size rather than an everyday one.
- 8.75 to 10 in: evenings, errands and anything where the bag should disappear.
- 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 is a feature rather than a compromise.
Price rises with width, but material moves faster
Price follows size, but not as steeply as you would expect. 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 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 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. Where spend is being optimised, material is the bigger financial decision and width the bigger practical one.
The bags with no number
Much of the line sits outside this system, and it is the mixing of the two conventions that breeds 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. 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 having no number. The N/S and E/W prefixes are shorthand for orientation, commonly read as north-south for taller shapes and east-west for wider ones.
Turning inches into a decision
What makes a literal sizing system useful is that you can test it before buying. Measure a bag you already own and like, then 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 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. If you are between sizes on a soft silhouette, the smaller one usually looks better and the larger one usually serves 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.
