Walking into a kitchenware store or searching online, 'glass jars with lids' all look similar-transparent, round, with a lid. But after bringing them home, problems arise: the size doesn't fit, the lid doesn't seal properly, or the contents get damp...
This article helps you understand how to choose a glass jar with a lid.
How to choose the capacity?
The capacity of glass jars is usually measured in ounces (oz) or milliliters (ml). Reference table:

|
4-8oz(120-240ml) |

|
12-16oz(350-475ml) |
Tea leaves, coffee beans, nuts, candies |
|
24-32oz(700-950ml) |
Flour, pasta, oatmeal, cookies |
|
64oz(1.9L) |
A large amount of useful content, kimchi |
How to choose the right lid?
Three common types of lids:
| SingleType | Sealing principle | Features | Suitable for |
| Glass lid + silicone ring | The glass lid is pressed tightly, and the silicone ring fits snugly over the jar opening | The best sealing performance | Dried goods, tea leaves, coffee beans |
| Screw cap (metal/plastic) | Tighten the thread and press the gasket together | Simple structure, easy to clean | Liquid, jam, kimchi |
| Bamboo and wood cover+silicone ring | Silicone ring seal, decorated with bamboo and wood | Natural texture | Candy, decoration, gifts |
Sealing test method:
- Fill with water, cover with lid, invert for 10 seconds
- Turn the jar upside down and shake it vigorously
- No water seeps out → Sealing is qualified

Q: Are brown glass jars better than transparent ones?
