The Row Size Numbers Made Simple: Margaux 10, 12, 15 and Beyond
At most luxury houses the sizes come labelled with adjectives. You are offered a Mini, a Small, a Medium and, when the house is feeling expansive, a Jumbo, and not one of those words promises a figure you can measure. The Row does something discreetly different across a large part of its line, and once you spot it the whole catalogue becomes easier to read. Whatever number turns up in a model name is the bag’s width in inches. Margaux 10 comes in at 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 from start to finish.
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. Look at the decimals, since nobody writes 15.75 unless the figure is meant literally. What follows is how far the rule holds, 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 coincidence. It is unusually honest labelling, because it closes the gap between what a size sounds like and what it measures. A Small from one house can be roomier 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 guessing. It also explains why the brand can run four sizes of one silhouette without muddling anybody.
| Model | Size number as width | Listed dimensions (W x H x D) |
|---|---|---|
| Soft Margaux 10 | 10 in | 10 x 7 x 7.5 in |
| Soft Margaux 12 | 12 in | 12 x 9 x the row terrasse bag 7.5 in |
| Soft Margaux 15 | 15 in | Width taken from the name; no measurements listed |
| Margaux Shoulder 12 | 12 in per the name | 14.75 x 9 x 5 in, which is the exception to the rule |
| Margaux 17 | 17 in | Given approximately as 17 x 12 x 9 in |
| India 10.00 | 10 in | Not published officially |
| India 12.00 | 12 in | No official figures published |
| India 15.75 | 15.75 in | Not published officially |
| Agnes 12 | 12 in | Width by name only |
| Agnes 15 | 15 in | Width from the name only |
| Marlo 12 | 12 in | Only the width, taken from the name |
| Marlo 14 | 14 in | Width by name only |
| Sofia 8.75 | 8.75 in | Archive model; not listed officially |
| Sofia 10 | 10 in | Archive model, not officially listed |
What the number will not tell you
One dimension of three is width, and the remaining two do not scale with it in any predictable way. Consider the two Soft Margaux sizes that have official figures behind them, since 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 proportional enlargement of the smaller one. Height is what shifts, by two inches, and width moves with it by the same. In practice, stepping up a size gets you a taller opening 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 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. Fittings inside differ as well: a single card slot on the 10, 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. Use the number to place the bag on a scale, then read the specification to make sense of it.
Where the rule bends: the Margaux Shoulder 12
A single current model breaks the pattern, and it deserves to be said 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. Name width and specification width do not agree here, so on this model the number serves as a family size rather than a literal external measurement. 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 plain scaling-up of the tote. Generalise the lesson, then, 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 actually holds
Most guides skip the step that does the work, which is translating inches into daily use. Anything under ten inches wide is a phone, cardholder, keys and lipstick affair, the territory of the Sofia 8.75 and the small clutches. Ten inches is the standard small day bag, enough for a compact wallet, a phone, sunglasses and a slim pouch without distortion. Twelve inches is where a bag starts 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 weekend and travel dimension rather than an everyday one.
- 8.75 to 10 in: evenings, quick errands and anything where the bag ought to disappear.
- 12 in: the most useful width in the line 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 trips, where the soft structure is a feature rather than a compromise.
Price follows width, though 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 considerably 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 weightier financial decision and width the bigger practical one.
The models that carry no number
Plenty of the line falls outside the system, and confusion sets in when the two conventions get mixed. The Park Tote family relies on 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. 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 treated 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. The N/S and E/W prefixes are orientation markers, commonly read as north-south for taller shapes and east-west for wider ones.
How to turn inches into a decision
The practical value of a literal sizing system is that you can try it before you buy. 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 suggests. Caught between sizes on a soft silhouette, you will generally find the smaller one looks better and the larger one 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.
