Look at what you normally mix after a feeding and how high it rises in your kitchen. A large jar can suit a baking build, while a smaller one gives a modest maintenance portion a visible starting level.
Check the mouth and lid
Compare the width of the opening against your spatula or hand for cleaning. Look at the lid and cover supplied and follow the maker's directions for active fermentation and storage.

Department questions
How do I compare a 12-ounce jar with a 32-ounce jar?
Compare your usual starter quantity and how much headroom each jar gives it. Read the maker's guidance for risen starter separately from full container volume.
What does a movable band tell me?
Mark the height just after feeding, then check the change at later times. Use a fixed graduation if you also want to record the actual height.
Do all jar kits come with a thermometer strip?
Check the exact contents. A graduated jar with a level band can be sold without a temperature strip or feeding-date band.
