As children grow, their needs evolve, especially when it comes to their sleeping arrangements. This comprehensive guide from Snuglee will help you determine the ideal bed size for your child at different stages of their growth.
Popular bed sizes for kids
Children's beds come in various sizes to accommodate their growth and changing needs. Here are the most common sizes:
- Toddler beds (Small single beds)
- Single beds
- Small double beds
- Double beds
- Space-saving beds (Bunk beds, Trundle beds, etc.)
How to determine the best bed size for your child
Stage 1: Toddler beds (1-3 Years)
A comfortable and safe bed plays a vital role in helping your toddler establish healthy sleep habits. Opting for the best beds for toddlers (1-3 years), such as a low Montessori-style bed, can support their independence and ensure a secure sleeping environment.

Stage 2: Beds for Preschoolers (3-5 Years)
As your child grows, upgrading to beds for preschoolers (3-5 years) provides more space and comfort. A playful design, such as a house bed or floor bed, can make bedtime more exciting while supporting their growing independence.

Stage 3: Beds for Kids (5-8 Years)
Children in this age range need a bed that balances comfort and durability. The best beds for kids (5-8 years) are often single or small double beds with enough room to stretch and play, while still being safe and cosy.
Stage 4: Beds for Preteens (8-12 Years)
Preteens require more space and support for their growing bodies. Beds for preteens (8-12 years), like standard double beds or cabin beds with storage, are ideal for maximizing comfort and functionality.
Stage 5: Beds for Teens
For older kids and teens, high sleeper beds for teens are a great space-saving option. These beds provide room underneath for a study area or extra storage, making them perfect for smaller bedrooms.

When a space-saving bed is top priority
For families with limited space or multiple children, space-saving beds can be an excellent solution.
Types of space-saving Beds
- Daybeds: Double as a seating area during the day.
- Trundle Beds: Provide an extra bed that can be stored under the main bed.
- Bunk Beds: Save floor space by stacking beds vertically.
- Cabin Beds: Feature built-in storage like drawers, cupboards, or desks.
- Shorty Beds: Shorter than standard single beds, perfect for small rooms.

Wondering when to transition from a toddler bed to a bigger one? Most children are ready between the ages of 3-5, but it's essential to consider their comfort and safety. Signs that it's time for an upgrade include frequent climbing out of the bed or needing more space to sleep comfortably.
