DOMMatrixReadOnly: translate() method

The translate() method of the DOMMatrixReadOnly interface creates a new matrix being the result of the original matrix with a translation applied.


DOMMatrix.translate(translateX, translateY)
DOMMatrix.translate(translateX, translateY, translateZ)



A number representing the abscissa (x-coordinate) of the translating vector.


A number representing the ordinate (y-coordinate) of the translating vector.

translateZ Optional

A number representing the z component of the translating vector. If not supplied, this defaults to 0. If this is anything other than 0, the resulting matrix will be 3D.

Return value

Returns a DOMMatrix containing a new matrix being the result of the matrix being translated by the given vector. The original matrix is not modified.

If a translation is applied about the z-axis, the resulting matrix will be a 4x4 3D matrix.


This SVG contains two squares, one red and one blue, each positioned at the document origin:

<svg width="250" height="250" viewBox="0 0 50 50">
  <rect width="25" height="25" fill="red" />
  <rect id="transformed" width="25" height="25" fill="blue" />

The following JavaScript first creates an identity matrix, then uses the translate() method to create a new, translated matrix — which is then applied to the blue square as a transform. The red square is left in place.

const matrix = new DOMMatrixReadOnly().translate(25, 25);

  .setAttribute("transform", matrix.toString());
