Kids Luggage Size Guide: What Suitcase Size by Age
As a general guide, toddlers under 5 do well with a 45cm to 50cm ride-on or small carry-on case, kids aged 5 to 8 suit a 50cm to 55cm carry-on, and kids aged 9 and up can usually handle a 65cm medium suitcase. The right size depends more on your child's height and how far they need to wheel it themselves than on age alone.
Why Size Matters for Kids' Luggage
A suitcase that is too big is heavy and awkward for a small child to steer through an airport. One that is too small means you end up packing your own bag with their clothes anyway.
Getting the size right means your child can actually pull their own case, and you get the packing space you need for the trip.
Kids Luggage Size Guide by Age
Use height and independence as your main guide, and treat age as a rough starting point only.
Ages 2 to 4
Toddlers
Most toddlers cannot steer a standing suitcase yet, so a ride-on case they can sit on works better than a walk-behind one.
Recommended: 45cm to 50cm ride-on suitcase
Ages 5 to 8
Young kids
This age group can usually wheel a small carry-on themselves over short distances, especially with a lightweight shell.
Recommended: 45cm to 55cm small carry-on
Ages 9 to 12
Older kids and tweens
Kids in this range are packing more for school camps and family trips, and a medium suitcase gives them the room without going oversized.
Recommended: 65cm to 66cm medium suitcase
Ages 13 and up
Teens
Teens can generally use an adult-sized case, though a large 75cm to 76cm suitcase still suits family trips where they are packing for a full week or longer.
Recommended: 65cm medium to 76cm large
Once you know the size, you can narrow further by browsing Luggage For Boys or Luggage For Girls to find a design your child will actually want to take on the trip.

Recommended Kids Luggage by Size
Small Ride-On Suitcases (toddlers)
A ride-on case lets a toddler sit and be pulled along rather than trying to walk and steer at the same time. Options like the Marvel Spider-Man Small Ride-On Suitcase and Disney Frozen Small Ride-On Hard Suitcase double as transport through a long airport walk.
- Sit-on design for tired little legs
- Hard shell for durability
- Licensed Disney and Marvel designs
Best for: toddlers who cannot yet manage their own wheeled case.
45cm to 55cm Small Hard Carry On (young kids)
This is the most popular size across Tosca's Small Kids Luggage range, covering Disney, Marvel, Batman, Harry Potter and Star Wars designs such as the Batman 50cm Small Hard Carry On and Disney Stitch 45cm Small Hard Carry On.
- Light enough for kids to wheel themselves
- Sized to fit most airline cabin allowances
- Wide range of licensed character designs
Best for: kids aged 5 to 8 travelling with a small amount of their own gear.
65cm to 66cm Medium Suitcase (tweens)
Once kids are packing for school camps or longer holidays, a medium suitcase from the Medium Kids Luggage range, like the Batman 65cm Medium Hard Suitcase or Disney Mickey Mouse 66cm Medium Hard Suitcase, gives them enough room without needing an adult case.
- Enough space for a week away
- Still light enough to check as standard baggage
- Available in hard and soft shell
Best for: kids aged 9 to 12 on school trips or family holidays.
75cm to 76cm Large Suitcase (teens and family trips)
A large case from the Large Kids Luggage range, such as the Batman 75cm Large Hard Suitcase or Disney Mickey Mouse 76cm Large Hard Suitcase, suits teens or a family trip where one child's case needs to hold more than a week of clothing.
- Holds a week or more of clothing
- Still a licensed design if your teen wants one
- Doubles as a spare case for family trips
Best for: teens and longer family holidays.
Trolley Backpacks (school-age alternative)
If your child needs something they can carry as a backpack one moment and wheel the next, the Marvel Avengers Trolley Backpack works as a hybrid option for school-age kids.
- Converts between backpack and wheeled trolley
- Good for kids who also need to carry it on stairs
- Sized for day trips or as hand luggage
Best for: kids who need to carry the bag as often as they wheel it.
Frequently Asked Questions
How do I choose the right suitcase size for my child?
Go by your child's height and how confident they are wheeling a bag rather than age alone. A child who cannot yet steer a standing case is usually better off with a ride-on suitcase, regardless of their age.
Can kids use a ride-on suitcase on flights?
Yes, a ride-on suitcase can go through the airport like any other wheeled case. Just check it fits within your airline's cabin baggage dimensions if you plan to carry it on.
What size is considered a carry on for kids' luggage?
Most kids' carry-on cases sit between 45cm and 55cm, which fits within the cabin baggage allowance for most Australian airlines. Always check the specific airline's size limit before you fly.
Should I buy a bigger suitcase so my child does not grow out of it?
It is better to size for what your child can manage now rather than buying ahead. A case that is too heavy or bulky for them to handle defeats the purpose of giving them their own luggage.
