How Much Coffee Per Cup

The Cup Size Confusion

The word "cup" means different things in coffee. Your coffee maker marks cups at 5 oz (148 mL), a standard coffee serving is 6 oz (177 mL), a US measuring cup is 8 oz (237 mL), and a typical mug holds 12 oz (355 mL). This calculator disambiguates these sizes and tells you exactly how much coffee to use.

Why Cup Size Matters

A "12-cup" coffee maker does not make 12 measuring cups (96 oz) of coffee. It makes 12 five-ounce cups (60 oz). Using the wrong cup size can result in coffee that is twice as weak or twice as strong as expected.

Examples

12-Cup Coffee Maker

12 cups on a standard drip coffee maker (5 oz each)

12 x 5 oz = 60 oz (1,776 mL) water. At 1:16 ratio, use about 111 g (21 tablespoons) of medium-ground coffee.

Key takeaway: Always check whether your coffee maker uses 5 oz or 6 oz cup markings.

Get the Right Amount Every Time

Match your cup definition to your actual mug or carafe markings.

  • Check your coffee maker manual for actual cup size (usually 5 oz)
  • Use a kitchen scale for the most accurate dose
  • When in doubt, start with 2 tablespoons per 6 oz of water

Frequently Asked Questions about How Much Coffee Per Cup

Why does my 12-cup coffee maker only make 60 oz?

Most coffee makers define a "cup" as 5 ounces (148 mL), not the standard US measuring cup of 8 ounces (237 mL). So a 12-cup coffee maker produces 60 ounces of brewed coffee.

What is the correct cup size for a coffee maker?

Nearly all drip coffee makers (Mr. Coffee, Cuisinart, Hamilton Beach) use 5 oz cups. Some European models use 4 oz or 6 oz. Check your manual or measure the carafe at the highest line and divide by the number of cups.

How do I measure coffee without a scale?

Use level tablespoons: about 2 tablespoons of medium-ground coffee per 6 oz of water. One standard coffee scoop equals 2 tablespoons (~10 g). For best consistency, keep your grind size the same each time.
