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

Adjectives are how most luxury houses handle sizing. 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. 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 is ten inches across. Margaux 12 is twelve inches. That one fact does more practical work than any amount of styling copy, and it runs through this explainer end to end.

The system runs further than the flagship alone. The 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 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 row bag.

The rule, put plainly

Read the number in the name, add the word inches, and that is the width you get. 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, 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 ten inches anywhere. For anyone comparing The Row bags to something already in their wardrobe, that makes the comparison arithmetic rather than guessing. It also explains how the brand can run four sizes of a single silhouette without confusing anybody.

What the number misses

Width is only one of three dimensions, and the other two scale with it in no predictable way to speak of. 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 not a straight scaling of the smaller one. What changes is the height, which adds two inches, and the width, which grows by the same. What that means in use is that a size up brings a taller opening and more length rather than extra depth. If you expect the 12 to hold twice what the 10 holds, the difference will be less 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 exactly 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 decide how a bag behaves day to day far more than an inch of width does. Use the number to place the bag on a scale, then read the specification to learn what it does.

The Margaux Shoulder 12, and where the rule bends

One current model breaks the pattern and it is worth stating clearly rather than quietly. The Margaux Shoulder 12 has a twelve in its name, yet the brand gives 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. 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 applies: use the number as your starting point, then confirm against published dimensions before you commit. Where a listing carries no dimensions at all, read the number as an indication rather than a measurement.

What each width really holds

The step most guides miss is translating inches into daily use. Under ten inches wide you are looking at a phone, cardholder, keys and lipstick proposition, which is where the Sofia 8.75 and the small clutches belong. At ten inches you have the textbook small day bag, taking a compact wallet, a phone, sunglasses and a slim pouch without distortion. At twelve inches a bag begins taking a paperback, a small notebook, a folded scarf and a full-size wallet all 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, 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 useful width in the line and the one most buyers settle on.
• 14 to 15 in: working days, commuting and the days you end up carrying other people's things too.
• 17 in: travel and overnight trips, where the soft structure is a feature rather than a compromise.

Price tracks width, but material moves faster still

Price follows size, but not as steeply as you would expect. 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 is observed 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. Material moves in larger jumps than size does, since 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. 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 larger financial decision and width the bigger practical one.

The models that carry no number

Much of the line sits outside this system, and it is the mixing of the two conventions that breeds 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. Small bags like the 90's Bag, the Half Moon and the Bourse Clutch carry no size indication at all. For those the dimensions are the only guide, so 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. No rule governs the archive models either, the Camden measuring 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, generally 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 with the number in the model name you have in mind. 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 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 implies. If you are between sizes on a soft silhouette, the smaller one usually looks better and the larger one usually performs 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.
