If this setting is too low, your brush strokes might feel too thick and opaque. The default setting is 7%, which produces a relatively realistic brush stroke-like result.

If you want your brush tip to have uneven dimensions, use the Roundness slider to shrink the brush tip vertically all the while preserving its horizontal size.If you don't want the pressure on your pen to affect the brush size, set this parameter to 100%. The minimum size is set to a percentage of your brush tip's maximum size, which is 25% by default.

If you are using a pressure-sensitive pen tablet, use the Minimum Size slider to set the size of your brush when using your pen with very little pressure.When drawing with a pressure-sensitive pen tablet, your brush's size will range between its minimum and maximum size, depending on the amount of pressure you put on the pen when drawing. NOTE: When drawing with a mouse, your brush is always at its maximum size.
