Quart freezer bags typically hold up to 4 cups or 32 ounces of liquid, while gallon freezer bags can hold up to 4 quarts or 128 ounces of liquid.

Quart freezer bags are a convenient option for freezing smaller portions of food, while gallon bags are better for larger items.

The main difference between a quart-size bag and a gallon bag is their capacity. A quart-size bag can hold up to 32 ounces of liquid, while a gallon bag can hold up to 128 ounces.

Quart size technically means, a quarter of a gallon. But while it’s a liquids bag you are not filling it up with water from the tap. You’re filling it with bottles and containers.
