How much space does a crib need?

CPSC's full-size crib guidance gives the inside of a full-size crib as 28 ± 5/8 by 52 3/8 ± 5/8 inches. The outside size makers publish is larger and varies by model; some full-size cribs we track are over 60 inches long. This guide lists the published outside sizes by type.

What is the smallest crib?

The chart in this guide lists the smallest footprints we track, by outside length times width from each maker's published dimensions. Mini and folding cribs take the least floor by median.

Do mini cribs take less floor than full-size cribs?

By median, yes: the side-by-side table gives the median floor each kind takes, from the makers' published outside sizes. Mini cribs take the mattress size the crib maker names, and some list a twin-bed conversion, per the maker.

Do all full-size cribs take the same mattress?

CPSC's full-size crib guidance gives a range for the inside size of a full-size crib. Check the mattress size and fit your crib's manual describes. The outside size varies with the frame.

Do mini crib mattresses fit every mini crib?

Not necessarily. The mini crib mattresses we track come in several different listed sizes. Buy the mattress size named in your crib's manual.

Can I fit two cribs in one room?

Add up both footprints plus a gap to reach each crib. The guide shows the median floor two mini cribs and two full-size cribs take.

How to Fit a Crib in a Small Apartment

Measure the floor you can give the crib, then compare it with the crib's outside length and width, not its mattress size. From the makers' published dimensions, a full-size crib we track takes a median of 11.4 sq ft of floor and a mini crib a median of 7.4 sq ft, about 35% less. The smallest footprint we track is the Nestig The Candy Cloud Crib at 30.3 x 22 in.

You’ve got a tape measure, a bedroom that already holds a bed and a dresser, and one open patch of floor. The crib has to fit there, rails and feet included.

Here are the 245 cribs we track that publish an outside size, lined up by the floor they take.

Full-size, mini or folding?

CPSC's business guidance for full-size cribs describes them as having "interior dimensions of 28 ± 5/8 inches" in width and "52 3/8 ± 5/8 inches" in length. The outside sizes makers publish vary more than that, and mini and folding cribs we track come in a range of sizes too. Here's how the three compare on the makers' own numbers.

Full-size means standard and convertible cribs. Sizes are the outside length and width each maker publishes; the meters are scaled to the largest number in the row.

Mini cribs take their own mattress. We track 34 mini crib mattresses in 9 different listed sizes, so match the size in your crib's manual. See mini crib mattresses.

Will it fit? Crib floor-space checker

Measure the open floor, wall to wall or wall to furniture, and enter both sides. We list the cribs whose outside size fits, smallest first.

Uses each maker’s published outside length and width, turned whichever way fits. Leave room to reach the crib and open doors and drawers. Check the maker’s manual for setup and placement.

Two cribs, one room
