# stroke-miterlimit

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.

## Usage context

Categories Presentation attribute | inherit 4 Yes SVG 1.1 (2nd Edition)
<miterlimit>
The limit on the ratio of the miter length to the `stroke-width`. The value of <miterlimit> must be a <number> greater than or equal to 1.

## Example

```<?xml version="1.0"?>
<svg width="120" height="500"
viewBox="0 0 120 500" version="1.1"
xmlns="http://www.w3.org/2000/svg">

<polyline stroke-linejoin="miter"
stroke-miterlimit="6"
points="-20,500 60,60 140,500"
stroke="black"
stroke-width="15"
fill="none" />

<polyline stroke-linejoin="miter"
stroke-miterlimit="5"
points="-20,700 60,260 140,700"
stroke="black"
stroke-width="15"
fill="none" />

<path d="M-20,500 L60,60 L140,500
M-20,700 L60,260 L140,700"
stroke="white" fill="none" />
