Crib vs. Mini-Crib Explained for New Parents

Crib vs. Mini-Crib

Welcome to the wonderful world of parenting! As you await the joy of your new child coming into the world, you are busily planning how your child’s nursery needs to be laid out. You want it to be perfect down to every detail. But it is easy to get overwhelmed with perhaps the most important choice—what kind and size of crib you need for your little one’s rest time. With that said, you may be wondering what the differences are between a standard crib and a mini crib. 

The most significant difference between a standard crib and a mini-crib is their size. Besides that, both offer their own advantages; standard cribs tend to last longer and are more durable, while mini cribs are more customizable and adaptable to different settings. 

This article will further help explain the differences between these two common types of cribs so you can determine which option works best for your child and your home. 

What Is the Difference Between a Mini-Crib and a Regular Crib?

Simply put, the major difference between a standard crib and a mini-crib is the size. A crib that is smaller in any way from a standard crib is, by definition, a mini-crib. 

A standard crib has dimensions mandated under federal law by the Consumer Product Safety Commission (CPSC). Mini-cribs, on the other hand, do not follow uniform standards for most of these categories. The dimensions are primarily dependent on the manufacturer and model. Nevertheless, there are still some ranges in which mini-cribs fall. 

The table below gives a comparison of the dimensions between the two types of cribs:

Mattress Length and Width52 inches by 28 inches (with only a variance of 5/8 inches permitted for either dimension)LENGTH – Ranges from 36 to 43 inches
WIDTH – Often the same as the standard, but some can be only 24 inches
Mattress Depth6 inchesRanges from 1 to 6 inches
Height of Crib Rail20 inches from the top of the mattress to the top of the crib railSame as standard
Height of Mattress Support6 inches off the groundTypically same as the standard, but regulation does not specify for mini-cribs

Simply put, you know exactly what you are getting as far as size when you purchase a standard crib. However, the variance in sizes of mini-cribs allows more flexibility in finding a crib to fit a tighter space in your home.

Standard Crib vs. Mini Crib: Safety Standards

Before further exploring the differences between standard cribs and mini-cribs, it should be noted that safety regulations apply equally to both types of cribs. Regulations are looser only as it pertains to the size of mini-cribs, not to their safety standards. 

Major updates were made to standardize crib safety features according to the 2008 Consumer Product Safety Improvement Act (CPSIA). Again, these apply to ALL cribs. These include the following:

  • Banning of Drop-Down Cribs – Due to numerous documented accidents, no cribs with the drop-down sideboard can be manufactured or sold in any way.
  • Regulating of Bed Slats – Before 2008, cribs could be made with lightweight and flimsy wood. These cribs would be susceptible to breaking, especially on the weight-bearing slats underneath the mattress. The new regulations mandate specific kinds of wood that are durable and capable of bearing the weight limit crib manufacturers advertise.
  • Increased Durability of Crib Hardware – Cribs must be equipped with hardware that prevents or deters the natural loosening of screws and bolts common with heavy use. This dramatically reduces the chance of accidents caused by equipment failure.

Why Use a Standard Crib?

What are the benefits of choosing a standard crib over a mini crib?  The most obvious advantage is in the standard crib’s history. Modern-day cribs date back to 1620, with these earliest varieties being little more than hollowed-out logs. However, numerous changes have allowed what we now call the standard crib to take shape, culminating in the first fixed set of federal standards from the U.S. Food and Drug Administration in 1973.

The process of standardization culminating out of 400 years of evolution has produced a crib with a wonderfully tested balance of size, functionality, and aesthetics. 


The standard measurements noted earlier are not simply random dimensions. They have grown out of hundreds of years of experience with the following contributing factors:

  • Room for Kids to Explore – The standard width and length allows plenty of room for infants as they begin to explore, roll, and eventually pull up on the sides of the crib. 
  • Conversion Ability – While not every standard crib is convertible, the vast majority of them possess the ability due to their size to grow with your baby. Standard cribs can convert to toddler beds, day beds, and often up to full-size beds (extra side rails and other accessories would need to be purchased).
  • Appropriate Height – Both standard and mini-cribs have regulated levels of bed-rail height (20 inches from the mattress) that, while not escape-proof, give the perfect balance of security and accessibility for parents to lean over and pick up or lay down their babies.


A major advantage to the uniform dimensions among different models of standard cribs is the ease of purchasing bedding. All you have to do is buy bedding for standard cribs. This is a crucial benefit over mini-cribs which are not uniform, and as such, leave you struggling to determine and then find the appropriate-sized bedding.

Additional Features

Because of their size, standard cribs can fit a variety of needs in your child’s bedroom. They are perfectly capable of being free-standing solely as a crib. But there are also standard crib models such as this that come with drawers and compartments that allow for the extra storage of bedding and toys. This is a wonderful feature in an area where space is already tight.

Why Use a Mini-Crib?

If standard cribs have so many strengths, why mess with a good thing? The answer is that the mini-crib can sometimes provide solutions to the needs of modern parents that standard cribs cannot. Mini-cribs differ in size precisely because a specific dimension might be the perfect fit within a room. Their size also presents a versatile functionality that separates them from standard cribs.

Built for Tight Spaces

As real estate prices soar, the reality that many parents face is trying to find an affordable house or apartment within both their budget and their space needs. As a result, parents may have to place the nursery in a smaller room, which will take great creativity in fitting all the necessary items.

A mini-crib gives you the ability to save a few precious inches of space in a tight nursery while also providing a safe environment for your child. 


While mini-cribs aren’t inexpensive, they are almost always less expensive than a standard crib. However, mini-cribs offer far more good quality options at lower prices than standard cribs do.

Note: You should never buy an inexpensive crib because it is the lowest price. Always research, look at ratings, and ask other parents you know what they use and like. 

Suitable for Multiple Children

Some of you may have the wonderful experience of expecting twins (or more!). But you are also probably sweating out the challenge of finding space for all your bundles of joy.

Mini-cribs are ideal when it is clear that two or more regular cribs are just not practical. Keep in mind that it is never a good idea to have multiple children in one crib. Especially if space is at a limit, mini-cribs give you added flexibility to give each child their own space while also allowing room for other necessary furniture in the nursery, as well as more open space for them to play and explore!

Added Sleeping Area 

Like many others, you may need to have your parents or others close to you taking care of your child for you a few days a week while you work or have some time to yourself. Instead of lugging a pack-and-play back and forth to these regular “babysitting” venues, purchasing an additional mini-crib to store in the guest room at your relative’s home gives your child a familiar place to hang out when they are there. 

Ease of Assembly

Unless you are an engineer or naturally gifted with your hands, you probably dread the process of assembling your crib. Mini-cribs will be much more attractive for you from this perspective. By design, all mini-cribs are smaller and more lightweight than standard cribs. As a result, it is less work to put together a mini-crib as the individual pieces are much easier to handle during the assembly process than those of a standard crib.


The lightweight nature of mini-cribs also makes them easier to move around the house. While not all mini-cribs are equipped with them, a good number of models also come with wheels, making transportation even easier. There are several advantages to this portability:

  • Move the Baby Wherever You Are – Instead of having baby monitors all over the house, just roll the mini-crib to wherever you happen to be as your baby naps or plays.
  • Allows the Baby to Have a Safe Spot in Your Room – You may especially want to have your child close to you at night when you are sleeping. A mini-crib can easily slide into your room without taking up too much space. The crib also provides you and the baby with a safe place and allows you to resist the natural but dangerous urge of placing your baby in the bed with you at night.
  • Cleaning the Nursery – When you can move your child’s crib more easily, the more quickly you can clean under and around it! No parent wants to see dust bunnies rolling around under their child’s crib. While a standard crib is not impossible to move, the mobile nature of the mini-crib gives you greater confidence that your child’s primary play and resting area are sufficiently clean.  

Standard Crib vs. Mini Crib: Which is Better? 

As you can see, the mini-crib offers several versatile features that make it more customizable to a specific family’s needs than a standard crib. However, the mini-crib’s adaptability also creates some limitations and weaknesses that should be considered before deciding.

How Long Can a Baby Stay in a Mini Crib?

The CPSC regulations stipulate that a child has outgrown a non-full-size crib (i.e., mini-crib) either when they can climb out or when they reach 35 inches. The CPSC is not as specific when it comes to weight, and so there is some variance among different manufacturers as to the weight limit. On average, the weight limit of mini-cribs is approximately 35 pounds. So 35-35 is a good rule of thumb for remembering the maximum limits for your child in a mini-crib.

For standard cribs, you often have more ability to lower the mattress. So, depending on the model, a child 35 inches tall still may be able to fit. The primary rule here is simply when they can climb out of the crib. While there is no standard weight limit, most standard crib manufacturers state a limit of 50 pounds in their safety manuals.

The bottom line is that your child will almost certainly have to transition out of a mini-crib long before a standard crib.

Sturdiness and Stability

The trade-off with having lighter materials is that a mini-crib is not nearly as sturdy as a standard crib. It does not imply that a mini-crib is dangerous, but a standard crib will absorb more use and abuse than a mini-crib because it is heavier.

In addition, mini-crib models that have wheels will inevitably be more unstable than a standard crib. Wheels are a great help for moving the mini-crib around. But even with brakes on, a mini-crib with wheels will rock and sway more readily than a standard or mini-crib without wheels.

Bedding Options

While finding a mini-crib to fit the size of your room is such an asset, it can be somewhat challenging to locate the sheet size that your particular style of mini-crib needs. The great benefit of a standardized size like a full-size crib is that accessories come in standardized sizes as well. Finding customized bedding for your mini-crib can be costly and time-consuming.

The most important litmus test for mini-crib bedding is to make sure it is snug and breathable and not loose (which may cause your child to get caught up in it).


While it is a CPSC regulation that mattresses should be sold with new mini-cribs, finding a new mattress can be very difficult if something happens to the original. Standard cribs have mattresses both of regulated length and width but also in thickness (6 inches). Mini-crib mattresses can vary in all of these dimensions.

As with bedding, it is vitally important to find the absolute perfect size mattress. If too small, your child could fall into the slats underneath or get caught between the mattress and sideboard. If too large, your child could get trapped in the extra material. It is a good idea to research the availability of mattresses and bedding for the mini-crib size you need before purchasing the crib.


As mentioned above, one benefit of mini-cribs is that they take up less space compared to the traditional crib. If you live in a small home or apartment and have limited room, a mini-crib may be a better option for your case. However, if you have ample space available for the baby, a standard crib will be just fine. 


It was mentioned before that the initial cost of mini-cribs is often less than standard cribs. However, with the factors listed above, you should still estimate the total costs you might anticipate over your baby’s life within a crib. This includes the following factors:

  • How long do you anticipate your child staying in the crib you select?
  • Will the crib convert into a larger bed?
  • How much money do you have budgeted for bedding and other accessories for the crib?

It is not always true that standard cribs cost less in the long run, but they often are. This is because, as mentioned earlier, mini-cribs usually don’t have the ability to grow with your child, so parents are often forced to purchase a new crib or another bed anyway. If possible, view the purchase of a crib as a long-term investment instead of what is the least costly at the beginning.

Final Thoughts

As you can see, you can get a safe and long-lasting crib for your baby, whether you choose a standard or a mini-crib. Both types are absolutely worth the investment if you have done your homework and figured out what works best for you. After all, the greatest investment is the health and joy of spending time with your new baby! The tools given here will help guide you into making a decision that will give you satisfaction and peace of mind.
