What The Row Size Numbers Mean: Margaux 10, 12, 15 and Beyond

Most luxury houses reach for adjectives when they label their sizes. A Mini, a Small, a Medium and, if the house is feeling expansive, a Jumbo: not one of them commits to anything you can measure. Across a large part of its line The Row does something quietly different, and the moment you notice it the catalogue becomes far easier to read. The number printed in a model name gives the bag’s width in inches. Margaux 10 measures ten inches across. Margaux 12 comes in at twelve. That single fact carries more practical weight than any amount of styling copy, and it is the backbone of this explainer.

The system runs further than the flagship alone. It takes in 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 intended literally. What follows sets out 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, spelled out

Read the number in the name, add the word inches, and that is the bag’s width. That is the system in full, applied consistently enough across the numbered families that it deserves to be treated as a rule rather than a coincidence. 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 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 estimation. It also explains why the brand can run four sizes of one silhouette without muddling anybody.

What the number will not tell you

One dimension of three is width, and the remaining two will not 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 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 smaller than the numbers imply.

Handle drop holds steady too, at five inches on both Soft Margaux sizes, one more detail the model number keeps to itself. 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. The interior fittings also differ, 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. Read the number to place the bag on a scale, then read the specification to know how it behaves.

Where the rule bends: the Margaux Shoulder 12

One model in the current line bends 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. The width in the name and the width in the specification fail to match, so the number is operating as a family size rather than as a literal external measurement on this one. It squares with the silhouette itself, a reworked shape with elongated tubular handles and narrowed gusseted side panels rather than a straightforward scaling of the tote. The lesson carries over: use the number as your starting point, then confirm against published dimensions before you commit. If a listing offers no dimensions at all, the number is a guide and not a measurement.

What each width will actually carry

Most guides skip the step that matters, which is translating inches into daily use. Anything under ten inches wide is a phone, cardholder, keys and lipstick proposition, the domain of the Sofia 8.75 and the small clutches. Ten inches is the classic small day bag, room enough 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, where documents and a tablet stop being a squeeze. Seventeen inches, as on the Margaux 17, reads as a travel dimension 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, travel to work and days when other people’s things travel with you.
• 17 in: travel and overnight trips, where the soft structure is a feature rather than a compromise.

Width lifts the price, but material moves faster

Size and price move together, though not as briskly as you might 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. Observed prices put Marlo 12 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. Bigger leaps 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. 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

A good deal of the line sits outside this system, and mixing the two conventions is where the trouble starts. 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. Small bags such as the 90’s Bag, the Half Moon and the Bourse Clutch are named without a size marker of any kind. 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 treated as approximate. Archive models follow no rule either, with the Camden measuring roughly 9 x 12.5 x 5.25 in despite having no number. The N/S and E/W prefixes are orientation markers, habitually 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 prove it before buying. 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 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. 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 lets on. Caught between sizes on a soft silhouette, you will generally find the smaller one looks better and the larger one works better. 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.
