Measure each wall along the floor, from baseboard to baseboard, not at eye level. That's the space furniture actually sits in. Measure all four walls, because rooms are rarely perfectly square and an inch can matter. Write the numbers in inches: "120 ร 132" is easier to work with than "10 ft ร 11 ft".
For each window note the distance from the nearest corner, its width (including the trim), and the sill height from the floor. A low sill limits what can go under it, and you'll want the crib away from windows and any blind or curtain cords.
Measure the door's width and note which side the hinges are on and whether it swings into the room. An in-swinging door sweeps a quarter circle as deep as the door is wide (most interior doors are 28โ32", 30" is common). Keep that zone empty. Do the same for a closet: sliding doors need no floor space, but swing doors need their own arc, and bifolds stick out about 12โ18".
Mark outlets (you'll want one near the chair for a lamp or sound machine and one by the changing area), heating and cooling vents, radiators, and light switches. Furniture in front of a switch or a floor vent is a common surprise.
Subtract the door, door swing, windows and closet from each wall. What's left is where furniture can go. In most bedrooms that's one full solid wall plus a few shorter stretches. This number matters more than the room's square footage.
Use the product's outside dimensions (length ร depth ร height), not the mattress or drawer size. Then add the floor space it needs to be used:
| Piece | Typical outside size | Add this in front |
|---|---|---|
| Full-size crib | About 53ยฝโ57" ร 29ยพโ31" | 24โ30" along the side you lift baby from |
| Mini crib | About 39โ40" ร 26" | 24โ30" along the open side |
| Dresser / changer | 18โ21" deep | About 36" to open drawers and stand |
| Glider or rocker | 28โ34" wide ร 30โ40" deep | If it reclines, often 15โ30" more depth |
| Walkway | 30โ36" is comfortable, 24" is tight |
Typical ranges, not specs for any one product. The US full-size crib inside is fixed at 28" ร 52โ " by federal rule; frames vary. See full-size vs mini crib dimensions and how much space a glider needs.
Got your numbers? Type them in (or snap 3 photos) and drag in the crib and dresser you're eyeing.
Try it with your room, free โMeasure the narrowest doorway, hallway and stair turn on the route to the nursery. An open door's clear opening is usually about 1ยฝโ2" less than the door itself because of the door's thickness and stop, so a 30" door gives roughly 28". Most cribs and dressers ship flat-packed, but a fully assembled dresser or a glider may not, so compare the box or item size to that number.

At the floor, from baseboard to baseboard. That's where furniture sits, and baseboards and trim can take up an inch or two compared with a measurement higher on the wall.
Outside dimensions for the room (the full frame, including posts), inside dimensions only for choosing the mattress.
About 36". Drawers pull out 15โ20", and you need room to stand in front of them.
30โ36" is comfortable. 24" works in a pinch, but it's tight when you're carrying a baby.
Measure the door's clear opening with the door open, which is usually about 1ยฝโ2" less than the door's width, and compare it to the smallest side of the box or the assembled piece.
