How to Use Path Length for Animations
The stroke-dasharray and stroke-dashoffset CSS properties let you create
line drawing animations. By setting both to the total path length, then animating
stroke-dashoffset to 0, you create the illusion of the path being drawn.
Step-by-Step
- Get your SVG path's
dattribute - Paste it above to calculate the total length
- Copy the generated CSS
- Apply the CSS class to your path element
JavaScript Alternative
var path = document.querySelector('path');
var length = path.getTotalLength();
path.style.strokeDasharray = length;
path.style.strokeDashoffset = length;
// Trigger animation
path.style.transition = 'stroke-dashoffset 2s ease-in-out';
path.style.strokeDashoffset = '0';
SVG Path Commands Reference
| Command | Name | Parameters |
|---|---|---|
M | Move to | x y |
L | Line to | x y |
H | Horizontal line | x |
V | Vertical line | y |
C | Cubic Bézier | x1 y1 x2 y2 x y |
S | Smooth cubic | x2 y2 x y |
Q | Quadratic Bézier | x1 y1 x y |
T | Smooth quadratic | x y |
A | Arc | rx ry angle large-arc sweep x y |
Z | Close path | (none) |
Lowercase commands use relative coordinates. Uppercase commands use absolute coordinates.
FAQ
Why do I need the path length?
For stroke animations, you need to know the exact length to set stroke-dasharray
and stroke-dashoffset correctly. If these values don't match the actual path length,
the animation won't look right.
What units is the length in?
The length is in SVG user units, which correspond to the coordinate system defined by your
viewBox. If your viewBox is "0 0 100 100", a path from (0,0) to (100,0) would
have a length of 100 units.
Can I animate multiple paths?
Yes! Calculate the length for each path separately and apply individual animations.
Use animation-delay to sequence them.
