Four compartments or five? It sounds like a small detail, but picking the right bento box layout genuinely changes how easy lunch packing is day to day. A 5 compartment bento box gives you one extra section to work with, and for some kids and some lunchboxes, that extra space makes all the difference. For others, four compartments is plenty. Here is how to figure out which suits your child.
Part of our complete guide to silicone baby feeding sets.
What a 5 Compartment Bento Box Actually Gives You
Five sections means more flexibility. You can separate foods that cannot touch (hello, sandwich-phobic kids), fit a small dip or sauce pot without crowding out the main meal, and still have room for fruit and a snack. It suits kids who eat a wider variety of foods, or who are in the phase where everything on the plate must have its own personal space.
It also works well for older children who need more volume. More compartments means you can spread food across the box without piling things on top of each other, which keeps everything fresher and more appealing when lunchtime rolls around.
The trade-off is size. A five compartment box is physically larger than a four compartment option. Worth checking it fits your child's bag before buying.
When Four Compartments Makes More Sense
For toddlers and younger children, four sections is often the better fit. Smaller hands, smaller appetites, smaller bags. A four compartment silicone bento is compact enough to pack easily, light enough for little ones to carry, and still gives you enough variety to build a balanced lunch.
Four compartments handles the classic lunch formula well: a main, a fruit, a vegetable, and a snack. If that covers your child's lunch most days, the extra section may just sit empty and add unnecessary bulk.

Silicone vs Hard Plastic: Why the Material Matters
Whatever compartment count you go with, the material is worth thinking about. Silicone bento boxes have a few practical advantages over hard plastic options.
- Silicone is flexible, so it is easier for kids to open and close without adult help.
- It is free from BPA and other plasticisers, which matters for food that sits in the box for hours.
- Silicone holds up in the dishwasher, handles temperature changes well, and does not stain or hold odours the way some plastics do.
- It is softer and lighter, which reduces the chance of damage if the box gets dropped or squashed in a bag.
For parents who want food-safe materials without the bulk and brittleness of hard plastic, silicone is a practical choice.
Building a Balanced Lunch in Either Box
A good bento lunch does not need to be complicated. The compartments do the work for you by making it easy to include different food groups without any thought.
A simple approach that works across both box sizes:
- One section for a protein or main, such as cheese, boiled egg, leftover pasta or a small sandwich cut to fit.
- One section for fruit, fresh or dried.
- One section for vegetables, raw sticks, cherry tomatoes or steamed florets.
- One section for a grain or carb, crackers, rice cakes or a small wrap.
- In a five compartment box, the extra section fits a dip, a sweet treat or a second snack.

Which One Should You Buy
A quick way to decide:
- Child under three or starting daycare, go with four compartments. Compact, lighter, and sized right for small appetites.
- Child at school who eats a wide variety or takes a larger lunch, try five compartments. The extra section earns its place.
- Fussy eater who needs foods strictly separated, five compartments gives you more room to work with.
- You want one box that does most jobs, four compartments handles the basics reliably.
Both sizes are available in our silicone bento boxes range, with options to suit toddlers through to primary school. If you are still deciding, browse the full collection to compare sizes and see what fits your child's routine.
