Mini Crib vs Full-Size Crib for a Small Room
Both crib types are federally regulated: full-size cribs must meet CPSC standard 16 CFR Part 1219, and mini or portable (non-full-size) cribs must meet the companion standard 16 CFR Part 1220, which carries equivalent slat-spacing and structural requirements adapted to the smaller frame — so a compliant mini crib is a regulated sleep space, not a lesser one.
The same rules, two standards
| Full-size crib | Mini / portable crib | |
|---|---|---|
| Federal standard | 16 CFR Part 1219 | 16 CFR Part 1220 |
| Slat spacing | 2 3/8 inch maximum | Equivalent slat-spacing requirements, adapted to the smaller frame |
| Structural rules | Yes — including the drop-side ban | Yes — equivalent requirements adapted to the smaller frame |
| Safe-sleep surface | AAP guidance is identical: firm, flat, bare — fitted sheet only, under 12 months | |

What to check either way
- The mattress fit: no more than two adult fingers of gap between mattress edge and frame on any side, whatever the crib's size.
- No missing, loose, or cracked slats.
- Buy new, never secondhand — see the drop-side ban.
- Register the crib and check CPSC.gov/Recalls.

Frequently Asked Questions
Both are federally regulated. Full-size cribs must meet 16 CFR Part 1219; mini and portable (non-full-size) cribs must meet 16 CFR Part 1220, a companion CPSC standard with equivalent slat-spacing and structural requirements adapted to the smaller frame.
Yes in effect -- 16 CFR Part 1220 carries equivalent slat-spacing requirements to the full-size standard's 2 3/8 inch maximum, adapted to non-full-size frames.
Yes. AAP safe-sleep guidance -- a firm, flat surface meeting federal safety standards with nothing but a tightly fitted sheet -- applies to the sleep space regardless of crib size, for infants under 12 months.
No. Crib Lab does not recommend secondhand cribs -- pre-2011 and recalled models (including all drop-side cribs) remain in circulation despite being illegal to sell.
