Here’s how Magnetic Me fits your child compared to other brands you might be considering, so you know before it’s in your cart.
Enter your child’s measurements once — we’ll size them in Magnetic Me and at 100+ other brands, each from that brand’s own published chart. Height and weight are required; add chest, waist, hips and inseam to sharpen the fit.
Magnetic Me publishes one unisex chart, so that is what we size against.
Pick the size your child wears at Magnetic Me to see which brands have the same label and measurements (twins) and which run shorter or longer (strangers) — based on each brand’s own chart.

Where the number just works. At PRE (preemie), 3-6M, 6-9M, 9-12M, Magnetic Me 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 4T, Polo Ralph Lauren Kids, Cat & Jack, Columbia Kids cut the same number differently. Check those before you trust the label.
Bottom line: for most sizes, a Magnetic Me number is a safe bet elsewhere — measure once, then double-check only the handful of “stranger” brands above.

Magnetic Me-specific things the size number alone won’t tell you — drawn from its own charts.
About 84% of buyers mark Magnetic Me true to size. The modal (bamboo-feel) footies and coveralls run a little roomy, so a size lasts longer; the organic-cotton pieces and two-piece PJ sets have less give and run snugger.
The recurring note is tight wrist and ankle cuffs on a solidly built baby — size up if your baby is chunky through the hands and feet.
Which trimmer, roomier, or adaptive cuts Magnetic Me publishes alongside its standard sizes.
This is what parents report anecdotally — crowd sentiment, not a Little & Youth determination. Our sizing above is computed from Magnetic Me’s own published chart; the notes here come from public parent discussion.
Magnetic Me runs true to size, and the modal styles lean roomy. On the brand’s own review-sizing question, about 84% of buyers mark it true to size, 11% ‘runs large’ and only 5% ‘runs small’ — and the split is mostly about fabric. The modal (bamboo-feel) footies and coveralls are stretchy and frequently described as running a little big, which parents like because a size lasts longer; the organic-cotton pieces and two-piece PJ sets have less give and are the ones called snug or ‘runs smaller than the modal’. The recurring specific complaint is tight wrist and ankle cuffs on a chunky baby, and Reddit parents of newborns are split: some say NB runs small and skip straight to 0–3, others found it spot-on or even loose on a preemie. Buy the labelled size in modal; consider one up in cotton.

Find my child’s size →Shop Magnetic Me ↗Mostly true to size: about 84% of the brand's reviewers say so, with the rest leaning 'runs large' (11%) over 'runs small' (5%). Modal footies and coveralls run a touch roomy; the organic-cotton styles and two-piece PJs are the snugger ones. Newborn is the exception where Reddit parents disagree — some find NB small and go straight to 0–3 months.
Not in the modal styles — order the labelled size and expect a little growing room. Size up in the cotton footies and two-piece sets if your baby is near the top of a weight range or has chunky wrists and ankles, since those have less stretch and tighter cuffs.
Parents consistently prefer the modal for fit: softer, stretchier and slightly roomier. The cotton is described as running smaller and stiffer, and one parent said the cotton PJs are 'more true to size vs the bamboo styles' — meaning less room to grow.
Reviewers report little shrinkage and no pilling with cool washes and low or delicate drying; a few air-dry the modal to be safe. Close the magnets before washing — parents who do say the magnets never loosen, while those who don't are the ones reporting bunching.
