Canning Jar Size Guide
Common canning jar sizes are 4oz and 8oz (half-pint) for jam and jelly, 16oz (pint) for pickles, salsa and sauces, and 32oz (quart) for larger batches and whole vegetables. Choose a size you will use up reasonably quickly once opened.
Small: jam and jelly
4oz and 8oz (half-pint) jars suit jam, jelly, marmalade and small-batch preserves, so each jar is finished before it can spoil once opened. They are also popular for gifting.
Medium: pints
16oz (pint) jars are the versatile everyday size for pickles, salsa, sauces, relishes and pie fillings. They hold enough for a meal or two and fit most recipes and canners.
Large: quarts
32oz (quart) jars suit larger batches, whole vegetables, tomatoes and anything you use in volume. Note that jar size affects processing time, so always follow a tested recipe for the exact size you use, and adjust for altitude.
