Dry vs Liquid Measuring Cups: The Real Difference

A common kitchen question: if a dry measuring cup and a liquid measuring cup both hold one cup, why own both? They do hold the same volume. The difference is how you use them accurately.

Dry measuring cups

These come in nested sets — ¼, ⅓, ½, 1 cup — and are designed to be filled to the very top and leveled off with a straight edge. You cannot level a liquid this way without spilling, so dry cups are made to be filled exactly to the rim.

Liquid measuring cups

These are clear, have a spout, and have measurement lines printed up the side with room above the top line. You fill to a line and read it at eye level. Trying to fill a liquid cup "to the brim" guarantees a spill and an inaccurate measure.

Which to use for what

• Flour, sugar, oats, cocoa: dry cups, spooned and leveled.
• Milk, water, oil, juice: liquid cup, read at eye level.
• Honey, peanut butter, sour cream: dry cups — these thick ingredients need to be scraped level, and a dry cup lets you do that.

The simplest answer

Skip the debate by weighing. A scale measures dry and wet ingredients with equal accuracy, in the same bowl, with nothing to level or read at eye level. Convert any recipe with our ingredient converters and the dry-versus-liquid question disappears.
