A practical guide to choosing the right Pyrex Simply Store rectangular glass container size for meal prep, leftovers, and snacks.
Quick answer
For single portions and small sides, choose the 1-cup round; for salads, snacks, or larger leftovers, the 3-cup rectangular is more versatile.
Size matters for everyday use
The 1-cup Pyrex Simply Store container is ideal for individual servings like yogurt, berries, or a single portion of soup. Its round shape fits easily in lunch bags and small fridge spaces.
The 3-cup rectangular container holds more volume and stacks neatly with other rectangular containers, making it a better choice for meal prep and storing side dishes or salads.
Lid compatibility and storage
Each size uses a specific lid: the 1-cup round requires the blue lid for 1-cup round containers, while the 3-cup rectangular uses the blue lid for 3-cup rectangular containers. Lids are not interchangeable between shapes.
If you plan to expand your set, consider buying multiple containers of the same shape so lids can be swapped within that size.
How to choose your size
- For single portions or sides: Choose the 1-cup round container when you need a compact option for dips, dressings, or a single serving of leftovers. Good for lunchboxes and small fridge spaces.
- For larger meals or meal prep: Choose the 3-cup rectangular container when you need to store salads, larger leftovers, or multiple servings. Stacks better with other rectangular containers.
- Check lid compatibility: Each size requires its specific lid. If you already own one size, adding the other means buying a separate lid set. Plan your set to avoid mismatched lids.
