Important Considerations for Loose Raisins:
When raisins are measured loosely (spooned into the cup without packing), they weigh less per cup than packed raisins. A common average for loose raisins is around **140-150 grams per US cup** (approximately 5 ounces).
Many baking recipes call for "packed" raisins, which would be heavier. See our chart for packed raisins if your recipe specifies that.
Different types of raisins (e.g., Thompson, Sultanas) may have slightly different densities.
For consistent results, especially in baking, clarifying whether to pack raisins or measure them loosely is important, or measure by weight.
