Why Size Matters for Lunches
A container that is too small means insufficient food. Too large and food slides around, gets messy, and takes up unnecessary bag space. Matching container size to portion size keeps lunches neat, fresh, and satisfying.
500ml — Snacks and Sides
Ideal for fruit portions, vegetable sticks with hummus, small salads, or children's snack boxes. Compact enough to fit in a small bag pocket.
800ml — Standard Adult Lunch
The most popular size for adult work lunches. Fits a generous portion of rice with protein and vegetables, a full salad, or a pasta dish. This is the size included in the SEIDO 3-pack.
1200ml+ — Meal Prep Portions
For large appetites or double portions. Suits hearty grain bowls, meal prep batches, or packing a main and side together. Useful for active individuals and batch meal prep.
Our Recommendation
The SEIDO 3-pack (3 × 800ml) covers most work lunch needs. The 800ml size is versatile enough for varied meals and the three containers give you a full week rotation.
