If you are into coffee brewing, one of the first thing that you will notice is that different brewing methods would require varying coffee grind sizes. One of the most confusing issue that new coffee brewers face is in selecting a suitable coffee grind size. This guide demystifies the selection of coffee grind sizes and provides you with a simple list to refer to before you start brewing your very next cup of coffee!
The Coffee Grind Range

A rough conversion of the numbers to the actual size
First up, always remember that the coffee grind size is made up of an incremental range of sizes rather than just 3 fixed, defined sizes. If you have used a coffee grinder, whether electronic or manual, you would have noticed that the adjustment of the grind is usually not fixed to just ‘fine’, ‘medium’ or ‘coarse’. Rather, each individual’s definition of a ‘fine’, ‘medium’ or ‘coarse’ coffee ground grind size may vary.
So, how do you tell if your grind size corresponds to the required grind size?
Well, here are some grind sizes you can use as a gauge!

Comparison of Coffee Grind Sizes
How the coffee grind sizes are obtained?
Depending on the grinder you are using, the gauge or presentation method of the grind size may vary. For some electronic grinders, a number is allocated to the grind size, with the larger number representing a larger grind size. Other grinders will only indicate how you can vary your grind size.
With hand grinders, the grind sizes can be varied by adjusting the distance between the grinder blades. For example, take a look at the YAMI Hand Grinder that we recommend;
By adjusting the screw in picture #3, you will control the distance between the blades. The nearer the blades, the finer the grind size.
