The most prevalent capacity for coffee makers is 12-cups. While this may sound like a lot of coffee, it is important to note that in standard measurements a "cup" of coffee is 6 fluid ounces. Most household mugs hold around 12oz of coffee, meaning these machines will produce around 5-8 mugs of coffee.
12-cup machines vary greatly in price, with an average of around $65. Most of the top ranked products have glass carafes and programmable settings.
