stroke-miterlimit

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.

The stroke-miterlimit attribute is a presentation attribute defining a limit on the ratio of the miter length to the stroke-width used to draw a miter join. When the limit is exceeded, the join is converted from a miter to a bevel.

Note: As a presentation attribute stroke-miterlimit can be used as a CSS property. See stroke-miterlimit for more.

You can use this attribute with the following SVG elements:

Example

html
<svg viewBox="0 0 38 30" xmlns="http://www.w3.org/2000/svg">
  <!-- Impact of the default miter limit -->
  <path
    stroke="black"
    fill="none"
    stroke-linejoin="miter"
    id="p1"
    d="M1,9 l7   ,-3 l7   ,3
       m2,0 l3.5 ,-3 l3.5 ,3
       m2,0 l2   ,-3 l2   ,3
       m2,0 l0.75,-3 l0.75,3
       m2,0 l0.5 ,-3 l0.5 ,3" />

  <!-- Impact of the smallest miter limit (1) -->
  <path
    stroke="black"
    fill="none"
    stroke-linejoin="miter"
    stroke-miterlimit="1"
    id="p2"
    d="M1,19 l7   ,-3 l7   ,3
       m2, 0 l3.5 ,-3 l3.5 ,3
       m2, 0 l2   ,-3 l2   ,3
       m2, 0 l0.75,-3 l0.75,3
       m2, 0 l0.5 ,-3 l0.5 ,3" />

  <!-- Impact of a large miter limit (8) -->
  <path
    stroke="black"
    fill="none"
    stroke-linejoin="miter"
    stroke-miterlimit="8"
    id="p3"
    d="M1,29 l7   ,-3 l7   ,3
       m2, 0 l3.5 ,-3 l3.5 ,3
       m2, 0 l2   ,-3 l2   ,3
       m2, 0 l0.75,-3 l0.75,3
       m2, 0 l0.5 ,-3 l0.5 ,3" />

  <!-- the following pink lines highlight the position of the path for each stroke -->
  <path
    stroke="pink"
    fill="none"
    stroke-width="0.05"
    d="M1, 9 l7,-3 l7,3 m2,0 l3.5,-3 l3.5,3 m2,0 l2,-3 l2,3 m2,0 l0.75,-3 l0.75,3 m2,0 l0.5,-3 l0.5,3
      M1,19 l7,-3 l7,3 m2,0 l3.5,-3 l3.5,3 m2,0 l2,-3 l2,3 m2,0 l0.75,-3 l0.75,3 m2,0 l0.5,-3 l0.5,3
      M1,29 l7,-3 l7,3 m2,0 l3.5,-3 l3.5,3 m2,0 l2,-3 l2,3 m2,0 l0.75,-3 l0.75,3 m2,0 l0.5,-3 l0.5,3" />

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 ratio is used to define when the limit is exceeded, if so 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:

stroke-miterlimit=miterLengthstroke-width=1sin(θ2)\text{stroke-miterlimit} = \frac{\text{miterLength}}{\text{stroke-width}} = \frac{1}{\sin\left(\frac{\theta}{2}\right)}

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.
