Find your child’s MarMar Copenhagen size on the left. Twins wear the same number the same way — your size carries straight over. Strangers use the same number but cut it shorter or longer, so don’t trust the label alone.

In short
Where the number just works. At 0M/50, 2M/56, 4M/62, 6M/68, 9M/74, 1Y/80 and more, MarMar Copenhagen lines up with every brand we track — the size carries straight over.
Where labels drift. The exceptions are the “strangers” above — e.g. at size 6Y, Brooks Brothers Kids, Polo Ralph Lauren Kids, Fabletics cut the same number differently. Check those before you trust the label.
Bottom line: for most sizes, a MarMar Copenhagen number is a safe bet elsewhere — measure once, then double-check only the handful of “stranger” brands above.

What shoppers say about the fit
Community consensus
Shopper opinion · not Little & Youth’s measurementThis is what parents report anecdotally — crowd sentiment, not a Little & Youth determination. Our sizing above is computed from MarMar Copenhagen’s own published chart; the notes here come from public parent discussion.
MarMar Copenhagen’s fit depends on the piece, and independent fit feedback is thin. Its signature modal-rib basics — bodysuits, leggings, rompers — are soft and stretchy and sit close to the body: one stockist calls the fit ‘true to slim,’ while another says MarMar runs slightly large with a generous cut, so even the retail read is split. The brand’s own notes are the clearer guide. MarMar says each size covers a small height window either side of its label and that it uses double sizes on its roomier, stretchier pieces such as outerwear and knitwear; product notes then flag the cut — its thermal suits are labeled slim fit, several jackets ‘roomy,’ and at least one kids’ coat ‘oversized.’ The few parents who mention size are mixed: one loves the fit of the modal bodysuits and leggings, one found her baby needed the next size up sooner than the label suggested, and one orders dresses with elasticated sleeves a size up so they last longer. On quality, most Trustpilot reviewers praise the softness and durability; a minority, mostly in older reviews, report pilling, small holes or fading after washing. It is a premium-priced brand.
Based on anecdotal discussion from multiple publicly available online sources; your experience may differ.
Should you buy MarMar Copenhagen?
Consider it if…
- You want soft, stretchy modal basics — softness is the most repeated praise on Trustpilot (‘soft as butter’), and the modal-rib bodysuits and leggings are where a parent singles out the fit.
- You want pieces that last and hand down — several Danish reviewers call the clothes durable, one saying they hold up for ‘many generations.’
- You like to read the cut before you order — MarMar’s product notes label pieces slim, loose, roomy or oversized, and its double sizes mark the items with extra give.
- You’re dressing several ages at once — a US parent of four says the range, from outerwear to swim, covers all her kids.
Think twice if…
- Your baby is long or growing fast — one parent found her son needed the next size up well before the label suggested; go by height on the chart rather than age.
- You want one clear fit verdict — stockists disagree (one says true to slim, another slightly large) and few parents comment on size, so check each item’s fit note.
- You expect flawless wear every time — a minority report pilling, pulls, small holes or fading after washing, mostly in older reviews; recent reviews are largely positive.
- You’re price-sensitive — a recurring complaint in older Danish reviews is that the quality didn’t match the premium price.

Does MarMar Copenhagen run big or small?
There isn’t a clear answer. The modal basics are stretchy and sit close to the body; one stockist calls the fit true to slim and another says slightly large, and the few parents who mention size range from ‘great fit’ to ‘needed the next size sooner.’ Size by your child’s height and read each item’s fit note.
How does MarMar’s sizing work?
Sizes are labeled by age and height in centimeters. MarMar says each size covers a small height window either side of its label, and it uses double sizes on roomier, stretchier pieces such as outerwear, knitwear and underwear.
Should I size up?
Not by default. One parent orders dresses with elasticated sleeves a size up so they last longer, which works because the sleeves gather. Pieces MarMar labels roomy or oversized already have room built in, while its thermal suits are cut slim.
How does the modal hold up in the wash?
Most reviewers praise the softness and durability, and several say the clothes hand down well. A minority, mostly in older reviews, mention pilling, fading, stiffening rib or small holes.
Is MarMar worth the price?
Recent Trustpilot reviewers mostly say yes for softness and quality (4.4 of 5 overall). Older Danish reviews include several who felt the quality didn’t match the premium price.
What measurements do I need to size MarMar Copenhagen accurately?
MarMar Copenhagen publishes height, chest, waist, hip, inseam, sleeve in its size chart. Height is the primary driver, and the chest/waist figures let you confirm body fit for a child between sizes.
How do MarMar Copenhagen’s sock sizes work?
MarMar Copenhagen’s socks are sized by shoe size, not age — buy for your child’s current shoe size, and if they fall between two ranges choose the smaller so the sock stays up. See how every kids’ shoe brand runs and how wide each is cut on our kids’ shoe sizing guide.
