How to scale icon from SVG sprite displayed in background?

Question

css

Packed all my SVG icons into one sprite. I want to display one of the icons in backgrounda size smaller than in the SVG itself, but it does not work.
The only thing that worked was to output as output, and then apply Like transform: scale();
this:

.my-div:before {
    content: '';
    position: absolute;
    left: 5px;
    top: 5px;
    height: 72px;
    width: 72px;
    background-image: url('../img/icons.svg');
    background-repeat: no-repeat;
    background-position: 0 -397px;
    transform: scale(0.52);
  }

But I think this is complete bullshit.
What do you think? How to do it right?
