# Coffee Grind Size Converter
Interactive grind size chart with clicks and levels guide for adjusting your grinder between Espresso, V60, French Press and more. Technical micron mapping for all extraction methods.Why doesn't the same grind setting work for all coffees?
Why doesn't the same grind setting work for all coffees?: Bean density varies by roast level and origin. A light roast is typically denser and requires a finer grind to extract properly, while a dark roast is more porous and needs a coarser setting.
How do I know whether to grind finer or coarser?: Let your taste guide you: if the coffee tastes bitter and dry, grind coarser so the water flows faster. If it tastes sour, salty or watery, grind finer to increase the contact surface area.
What is 'channeling' and how does grind affect it?: Channeling occurs when water finds a path of least resistance through the coffee bed. An uneven or inappropriate grind for the pressure, especially in espresso, encourages this problem and ruins extraction.
Can I use this chart with a blade grinder?: Blade grinders produce non-uniform particles, fine powder and large chunks simultaneously. The micron values are indicative, but actual results will vary significantly compared to a burr grinder.

Use the diagnostic guide at the bottom as a reference. If coffee tastes bitter, go a couple of clicks coarser. If it tastes sour, go finer. Always adjust one step at a time.
