While different models of Keurig coffeemakers will have different options for cup sizes, they all have onething in common--the buttons you press to brew a cup of coffee havepictures of what sort of cup you should put under there, but sometimesit's hard to guess if an odd-shaped mug will hold the volume of coffeethat's about to be brewed.
  How can you avoid overflows or half-emptymugs? Use this handy guide to understand the four most common Keurigcoffee maker brew options.
While the more upscale models will offerthree or four of these, some of the models will offer only one or two.
Keep that in mind as you determine which options you have availableon your Keurig coffee maker.
  6oz - This will brew the most intensecup of coffee.
While it is still designed to fill a normal sized coffeemug (the standard size you get for free at conventions and have stuffedall the way to the back of your cupboards) it won't fill it all theway up.
This is a particularly useful setting if you like to have extracream or sugar in your coffee but don't want to lose an excessiveamount of flavor.
  8oz - This is a normal cup of coffee.
It will be moderately strong and fill a normal sized coffee mug up tothe top, with a little room for a tub or two of creamer.
  10oz - This will overflow a normalsize coffee mug.
Beware.
Best suited for slightly larger mugs or smalltravel mugs, this setting is also good if you're not a fan of extremelyrobust coffee.
There will still be a strong flavor, but it will be noticeablyless strong than the previous two settings.
  12oz - This size is best suited toextremely large mugs (such as the taller kind commonly for sale at coffeeshops) or travel mugs.
  Keep this guide in mind as you shopfor or use your own Keurig coffee makers.
Knowing what those littleflashing buttons really mean can help you avoid spills or underfillyour favorite mug.
