When two line segments meet at a sharp angle and miter joins have been specified for stroke-linejoin, it is possible for the miter to extend far beyond the thickness of the line stroking the path. The stroke-miterlimit imposes a limit on the ratio of the miter length to the stroke-width. When the limit is exceeded, the join is converted from a miter to a bevel.

The ratio of miter length (distance between the outer tip and the inner corner of the miter) to stroke-width is directly related to the angle (theta) between the segments in user space by the formula:

miterLength / stroke-width = 1 / sin ( theta / 2 )

For example, a miter limit of 1.414 converts miters to bevels for theta less than 90 degrees, a limit of 4.0 converts them for theta less than approximately 29 degrees, and a limit of 10.0 converts them for theta less than approximately 11.5 degrees.
