How to Measure Nursery for the Perfect Crib Fit

1. Accurately Measure Your Nursery

Use a tape measure or other measuring tool to get the correct measurements of the room. You can do this alone but help from another person might help you get more accurate dimensions. Measure severally from different starting points to account for any errors. 

2. Identify the Crib’s Placement Area

Measuring the room will help you determine the available space for the crib. The room’s dimensions will also help you pick the correct crib size. The next step is choosing the area where you will place the crib. 

The crib should be placed near the nursery’s door and away from windows and other furniture. Ensure that the crib fits the placement area. 

3. Check the Layout of the Room

After selecting the area you will put the crib, get your preferred crib, and place it in the room. This will help you examine the room’s layout and determine whether the crib is perfect for the nursery.

4. Plan for the Future

The crib may be perfect for the room but babies grow and when they do their needs also change. Will the crib still fit when the baby starts growing and you have to convert the crib to a toddler bed? Plan for your baby’s future needs.

Apart from their compact size, they are ideal for smaller spaces as most are portable or foldable. They can be carried to other rooms or folded to create space.

The dimensions of oversized cribs vary but their standard measurement is 60 by 31 inches. Due to their size, they have extra room for growth and can have a higher age limit than other crib sizes. 

Oversized cribs are suitable for larger nurseries and homes. The larger rooms allow for a good placement of the crib away from the windows, furniture, and hanging fixtures.

Despite their larger size, oversized cribs are still safe for use by newborns. Their age limit is quite higher than the age limits of other crib types. They can be used until the ages of 3-4 years. 

Typical Features: 

  • Larger than standard and mini cribs
  • Suitable for larger nurseries
  • More Spacious

Advantages

  • They can fit bigger babies. Babies grow very fast, when they get to 2 or 3 years old, they can no longer fit inside the crib. This forces parents to spend on beds sooner. Oversized cribs extend the period of use for babies to 3 to 4 years and parents have a longer period to budget for baby beds. 
  • They are safer for use by babies. Some babies are bigger but are not yet old enough for beds. Oversized cribs are perfect for them as there is no risk of them bumping their heads.

Convertible cribs generally have the same dimensions as the standard crib size. The cribs can be converted to a toddler bed, daybed, and even a full-sized bed. The design allows your baby to use the crib as they grow. 

When the crib was converted into a toddler bed and sofa bed, its main dimensions remained largely unchanged removing some of the side rails. Converting to a full-size bed involves removing all of the crib’s sides and rails and installing a bed conversion kit, which significantly expands the dimensions to a new size that is typically approximately 54 x 75 inches (a standard full-size bed).

Conversion Options:

  • 2 in 1 
  • 3 in 1
  • 4 in 1

Advantages:

  • They grow with your child. When your baby outgrows the crib, you can convert it into a toddler bed and they can continue to use it. Some can be converted into a full-size bed and used for longer periods. 
  • They are economical. Convertible beds can be used for a long time and you do not need to spend money replacing them, unlike other cribs.

Each crib has typical standard crib dimensions. They measure 52/53 by 28 inches, their mattresses measure 27 x 51. They are designed for twins and allow parents to optimize space. 

Although they can be detached into two cribs, it is wise to keep them attached when you want to maximize space. Additionally, when twin babies sleep where they can see and touch each other, they sleep better and can bond well. 

Typical Features: 

  • The cribs can stay attached or separated into two cribs

Advantages
