How to size a crib for your space
Measure clearance, not just the room
US-standard crib mattresses are 27.25″×52″, with the crib interior fitting that within 1/2″ per the safety standard. Mini cribs are 24″×38″. Allow 24″ behind the crib if it's on a walkway, and 36″ on at least one long side for parent access.
Walkways and door swing
Plan at least 30″ for primary walking paths and 24″ behind seating that backs up to a wall (e.g., dining chairs that need to slide out). Closet, oven, and refrigerator doors all need full swing clearance — a piece that fits the floor space but blocks a door is the wrong piece.
Delivery path before you order
Measure the narrowest point in the delivery path: front door, hallway turn, stairwell, elevator. A sofa that fits the room can still be impossible to deliver. The diagonal of a doorway is what matters, not the doorway width — tilting helps but not always enough.
Common mistakes
- Choosing a piece that fills the room dimensions exactly — rooms need negative space to feel comfortable.
- Ignoring the height of nearby fixtures (windowsills, light switches, baseboards) that limit where the piece can sit flush.
- Forgetting that rugs reduce usable clearance by 1–2″ on each side.
