The scale component defines a shrinking, stretching, or skewing transformation of an entity. It takes three scaling factors for the X, Y, and Z axes.

All entities inherently have the scale component.


The example below shrinks the entity in half along the X direction, maintains the same scale factor along the Y direction, and stretches the entity by two-fold along the Z-direction:

<a-entity scale="0.5 1 2"></a-entity>


A-Frame uses a right-handed coordinate system. When aligning our right hand’s thumb with a positive axis, our hand will curl in the positive direction of rotation.

If we set any of the scaling factors to 0, then A-Frame will assign instead a negligible value.

Axis Description Default Value
x Scaling factor in the X direction. 1
y Scaling factor in the Y direction. 1
z Scaling factor in the Z direction. 1


Scaling factors can be negative, which results in a reflection.

A notable use for this is for sky spheres. Sky spheres contain the entire scene and have a texture mapped on the interior surface. To do this, we can reflect, or invert, the sphere in the Z-direction.

<a-entity geometry="primitive: sphere; radius: 1000"
material="src: sky.png"
scale="1 1 -1"></a-entity>

Relative Scale

Similar to the rotation and position components, scales are applied in the local coordinate system and multiply in nested entities.
