In short
Where the number just works. At Up to 5lb, Preemie, 36M, 6 / 6X, 6X, Little Planet by Carter's 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 5, Il Gufo, Converse Kids, Levi's Kids cut the same number differently. Check those before you trust the label.
Bottom line: for most sizes, a Little Planet by Carter's number is a safe bet elsewhere — measure once, then double-check only the handful of “stranger” brands above.

Fit & the transitions that trip parents up
Little Planet by Carter's-specific things the size number alone won’t tell you — drawn from its own charts.
Shares Carter’s size chart
Little Planet is Carter’s organic sub-brand and uses the same chart, so the numbers carry straight over from Carter’s.
Slim, Plus and Husky cuts (sizes 4–14)
Like Carter’s, Little Planet offers Slim, Plus and Husky alongside the regular cut in kid sizes 4–14 — each the same height, adjusted through the waist and seat.
Age-range labels, and the cotton can shrink
The labels are age ranges — a “3M” means 0–3 months — and the organic cotton can shrink slightly in the wash, so a child near the top of a size often prefers the next one up.
Specialty & inclusive fits
Which trimmer, roomier, or adaptive cuts Little Planet by Carter's publishes alongside its standard sizes.

Should you buy Little Planet by Carter's?
Consider it if…
- You want GOTS-certified organic cotton — Little Planet is Carter’s organic line, made with certified-organic and recycled materials.
- You want affordable organic — organic basics at closer to mainstream prices, not a boutique-organic markup.
- You want soft baby-and-toddler basics — bodysuits, sleep & play, and coordinated organic sets.
