Choosing the right cot for your baby is one of the most important decisions new parents will make. The dimensions of the cot are not just about fitting it into your nursery; they play a crucial role in ensuring your baby’s comfort and safety.
But with so many options out there, understanding the ideal cot dimensions can be confusing. How do you know what size is best for your growing baby? And what about the mattress? In this guide, we’ll help you navigate these questions and make the right choice for your little one.
Why Cot Dimensions Matter More Than You Think

When it comes to baby cots, size does matter. Not only does the cot need to fit well into your nursery, but it also needs to provide a safe, comfortable sleeping environment for your baby. Cots that are too small could make your baby feel cramped as they grow, while cots that are too big might pose safety risks.
For Australian parents, standard cot sizes generally fall within a certain range, but knowing the exact dimensions you need can make a world of difference when shopping for a cot or planning your nursery layout. Let’s explore why choosing the right cot size is so essential.
The Standard Cot Dimensions in Australia
In Australia, the standard dimensions for a cot are typically around 130 cm in length and 69 cm in width. However, variations exist, and depending on your space or specific needs, you may want to go for a cot that’s slightly larger or smaller. Below is a general guide to common cot dimensions:
| Cot Type | Dimensions (Length x Width) | Mattress Size | Suitable Age Range |
| Standard Cot | 130 cm x 69 cm | 130 cm x 69 cm | Birth to 4 years |
| Compact Cot | 100 cm x 50 cm | 100 cm x 50 cm | Birth to 2 years |
| Toddler Cot Bed | 140 cm x 70 cm | 140 cm x 70 cm | Birth to 5 years |
Mattress Considerations
While cot dimensions are important, don’t forget about the mattress. It’s crucial that the mattress fits snugly into the cot with no more than a 2 cm gap between the sides of the mattress and the cot. This ensures that your baby doesn’t get trapped between the mattress and the cot’s side rails, which can be a safety hazard.
Choosing the Right Cot Size for Your Nursery
Before purchasing a cot, it’s essential to measure your nursery space. You want to make sure that the cot fits comfortably in the room, with enough space to walk around it and place other necessary items like a changing table, rocking chair, or storage units. Measure the dimensions of your room, and then compare those measurements to the cot you’re considering.
Tips for Making the Most of Your Nursery Space
- Smaller nurseries: Consider a compact cot if space is tight. These cots are slightly smaller than standard cots, making them ideal for apartments or smaller homes.
- Larger nurseries: If you have a larger room, you can opt for a toddler cot bed, which will last longer as your child grows. This makes it a more economical choice in the long run.
- Portable options: For those who travel often, a portable cot is a great choice. Look for a model that folds up easily and is lightweight, so you can take it with you on family trips.
One great option is our Snoozy Monkey Inflatable Toddler Travel Bed with Safety Bumpers. With dimensions of 12 x 61 x 40 inches, it provides ample space for your toddler to sleep comfortably while offering portability for those on the go.

The inflatable design ensures it’s easy to pack and set up, while the safety bumpers add extra peace of mind for parents. Whether you’re staying at a hotel, visiting family, or going on a camping trip, this bed makes traveling with toddlers much easier.
The Benefits of a Well-Sized Cot
Beyond fitting into your nursery, the right cot size has practical benefits that can help both you and your baby.
- Better sleep: Babies who sleep in a cot that’s appropriately sized will feel more secure, promoting better sleep.
- Longevity: A cot that’s slightly larger (such as a toddler cot bed) will last longer, making it a smart investment.
- Safety: The right dimensions ensure that the cot meets safety standards, preventing hazards like entrapment.
Our Snoozy Monkey Baby Lounger is a perfect example of how a well-sized baby bed can provide both comfort and safety. With dimensions of 76 x 49 cm, it’s designed to give your newborn a snug, secure environment while still offering enough space for them to move. It’s perfect for newborns and infants who need a little extra comfort during sleep or playtime.
Cot Safety Standards: What to Look For
In Australia, all cots must meet certain safety standards to ensure your baby’s protection. When shopping for a cot, look for these key features:
- Fixed sides: Ensure that the cot has fixed sides that don’t drop down, which is now considered a safety hazard.
- Slat spacing: The slats on the sides of the cot should be no more than 2.5 cm to 6 cm apart to prevent your baby from slipping through or getting stuck.
- Sturdy construction: The cot should feel solid and not wobble when you move it.
By choosing a cot that meets these standards and has the right dimensions, you can rest assured that your baby is sleeping in a safe, secure environment.
How to Choose the Perfect Cot for Your Baby
Now that you know the ideal dimensions of cot, how do you make the final decision? Here are some key factors to consider:
- Longevity: Think about how long you want the cot to last. If you want a cot that grows with your child, opt for a larger cot bed.
- Portability: Do you need a portable cot for travel? If so, look for lightweight and foldable options like the Snoozy Monkey Inflatable Toddler Travel Bed with Safety Bumpers.
- Comfort: Ensure the cot has a snug-fitting, high-quality mattress to keep your baby comfortable during sleep.
- Aesthetic appeal: Don’t forget about style! Choose a cot that matches your nursery decor but also meets safety and size requirements.
