What Size Is Right for Me?

A Guide to Dreamroo Bentos & Food Storage Containers

When it comes to packing lunches or storing food, the right container makes everything simpler. Too small and it won’t fit enough food. Too large and it takes up unnecessary space.

The goal is finding the container that fits your lifestyle, your meals, and your family’s needs.

Let’s break down each option.


Bento & Lunchbox Sizes

Classic Bento

Best for:

  • Snacks

  • Light lunches

  • Toddlers and younger kids

The Classic Bento is the perfect starter size. It’s compact and easy to carry while still giving you compartments to separate food.

Great for:

  • daycare lunches

  • small appetites

  • snack-style meals

Example meal ideas:

  • crackers, cheese, and fruit

  • yogurt, granola, and berries

  • mini sandwiches and veggies

If you’re packing lighter lunches or snack plates, this size works beautifully.


Everyday Bento

Best for:

  • School lunches

  • Older kids

  • Balanced meals

The Everyday Bento is larger than the Classic and holds about 1000 ml, making it perfect for full lunches.

This size is ideal when you want to pack:

  • a sandwich

  • fruit

  • veggies

  • snacks

Example lunch:

  • sandwich

  • strawberries

  • cucumber slices

  • crackers

For most families, this becomes the go-to everyday lunchbox.


Duo Bento

Best for:

  • Simple meals

  • Larger portions

  • Teens or adults

The Duo Bento keeps things simple with two larger compartments (approximately 600 ml and 400 ml).

Perfect when you want to pack:

  • leftovers and a side

  • pasta and fruit

Example lunch:

  • turkey sandwich

  • grapes or chips

It’s also great for meal prep or quick lunches on the go.


Flex Bento

Best for:

  • Variety meals

  • Picky eaters

  • Grazing lunches

The Flex Bento offers five compartments, making it ideal for variety.

Great for:

  • snack-style lunches

If your child loves options (or prefers foods separated), this is a favorite.
