Measuring Cup Sizes & How They Differ

Learn about measuring cup sizes.

The ability to obtain precise ingredient measurements – whether for liquid or dry – is foundational to the art of baking. Truth be told, baking is more of a science with exact ratios and specific techniques that all work together to create delicate confectionaries, delectable treats, and wholesome home goods from your kitchen. The question is – what do you use to get those accurate measurements? Measuring cups of course! Keep reading to discover more about measuring cup sizes, how they affect your baking, along with the different types of sets and options available to you.


Measuring Cup Sizes

Before you can delve into the standard measuring cup sizes, is it important to first understand the difference between liquid and dry cups.


Measuring Cup Types

Liquid Measuring Cup: This typically looks like a jug with a handle and single pointed spout. Due to the fact that fluids are measured and behave differently than dry ingredients, a cup-like vessel is better suited to the task. They are easy to decant into while the spout makes it easy to pour the liquids (using the handle) into your mixing bowl. They are also most typically made from glass or clear plastic materials.

Dry Measuring Cup: Dry ingredients like powders (flour and sugar) and solids (grains, nuts, etc) typically need to be scooped into the cup and then leveled out using a knife or flat tool. While it is most common to use only a single liquid measuring cup (due to its larger capacity), dry measuring cups usually come as a set featuring a range of sizes (or as sets that include measuring spoons) for you to more easily calculate the required weights. These are usually made from materials like stainless steel and plastic.

Standard Measuring Cup Sizes

When it comes to measuring cup sizes, you will often find at least two and sometimes three units of measurement on each one.

  • The most common unit is cups and fractions thereof – this is especially helpful when you need to figure out how many cups in a quart for example.
  • The second is imperial units, like ounces.
  • And finally there are metric units, which come in milliliters and liters.


Liquid Measuring Cup Sizes: The jugs/pitchers will usually have measurement marks printed up the side in ascending order with zero at the bottom going up in 1/4-cup increments. Typically a liquid measuring cup will only hold one cup's worth of liquid (often with ounce/millimeter measurements alongside them). It is, however, possible to find larger options that hold up to two or even four cups – these are ideal if you often measure large quantities of liquids.

Dry Measuring Cup Sizes: These smaller cups are individually marked with the measurement of the utensil. They start with the smallest unit of 1/4 a cup (some may begin with 1/8 cup), and continue upward through 1/3 cup, 1/2 cup, and finally 1 cup. Again, it is easier to break down one cup into smaller units of fractions to more accurately calculate each of the ingredients.

Shop Dry Measuring Cups

Measuring Spoon Sizes: Measuring spoons can be purchased on their own or as a set with dry measuring cups. They mark the smallest units of measurements possible beginning with 1/4 teaspoon, 1/2 teaspoon, 1 teaspoon, and 1 tablespoon (3 teaspoons). These spoons can typically be used to measure both dry and liquid ingredients due to their small volume.

Baking Measuring Rules

  1. Apart from measuring smaller amounts of liquids (like extracts using a dry measuring spoon), liquid and dry measurements are not interchangeable.
  2. In order words, you need to use the jug solely for liquids and the cups for dry ingredients, otherwise you can easily get inaccurate readings.
  3. If the dry ingredients are placed in a measuring jug, they cannot be correctly leveled out and potentially even compacted, resulting in too much of the ingredient.
  4. Filling a dry measuring cup with a liquid can be a challenge and also result in false readings because of the surface tension of liquids (it's easy to overfill).
  5. When measuring liquids, place the jug on a flat surface, pour into the top, and bend down to read the measurement at eye-level.


Measurement Conversions

Another reason cups and fractions of cups are so important is they allow you to resize your recipes. It is crucial to be able convert measurements for instances where you are multiplying or cutting a recipe down. Below are the liquid and dry measurement conversions for your convenience.


Liquid measurements converts as follows:

  • 1 fluid ounce = 2 tablespoons.
  • 1 cup = 8 fluid ounces.
  • 1 pint = 2 cups or 16 fluid ounces.
  • 1 quart = 2 pints or 32 fluid ounces.
  • 1 gallon = 4 quarts or 128 fluid ounces.


Dry measurements convert this way:

  • 1 tablespoon = 3 teaspoons.
  • 1/4 cup = 4 tablespoons.
  • 1/3 cup = 5 tablespoons + 1 teaspoon.
  • 1/2 cup = 8 tablespoons.
  • 1 cup = 16 tablespoons.


Now that you can more accurately discern between the different measuring cup sizes, you are able to effortlessly improve your baking skills by obtaining the most precise numbers each recipe calls for!
