A standard crib is 28"x52", but a nursery also needs a changing area, rocker, and storage. See the minimum room size and how to plan the layout safely.
Whether it fits comes down to the measurements most people skip.
Real openings run about 1 to 2 inches under the labeled size, and a single inch can flip the result. Check your own measurements before you buy or move.
Verdicts compare all six item orientations against the space using verified building standards. See our methodology

Most “it didn't fit” stories trace back to one of these oversights.
Frequently asked
A 9x10 foot room (90 sq ft) is the minimum for a functional nursery with a crib (30"x55"), a dresser/changing table (36"x20"), and a glider (30"x38"). This leaves clear walking paths and room to access the crib from the long side.
01A large walk-in closet (6x8 feet or bigger) can fit a crib, but it is very tight. There is no room for a glider, the ventilation may be inadequate, and you need to verify the space meets local building codes for a sleeping area (egress window, smoke detector).
02Standard cribs accommodate babies up to 35" tall, which is typically 18-24 months. Plan the room layout knowing you will transition to a toddler bed (27"x52") or twin bed (38"x75") within 2-3 years — make sure the room can support the upgrade.
