Get element height with Vuejs

I want to get the height of a div in order to make the height of another div matching it. I used the method clientHeight, but It doesn't return me the good value (smaller value). Actually, It seems to return a height before all elements are charged. After some research online, I tried to put a window.load() to delay until everything is charged but it doesn't work as well. Some ideas ?

mounted () {
  this.matchHeight()
},
matchHeight () {
  let height = document.getElementById('info-box').clientHeight
}
<div class="columns">
  <div class="left-column" id="context">
  <p>Some text</p>
  </div>
  <div class="right-column" id="info-box">
    <img />
    <ul>
      some list
    </ul>
  </div>
</div>

Took a lot of time ⌚ resolving the issue. Initially I tried to follow answer by Ron C. Trying to get this.$refs.infoBox.clientHeight; just didn't work - it gave undefined.

Then I explored the this.$refs.infoBox object.

Wow!!! I don't know how the code he wrote works for him and all others, but there wasn't any property called clientHeight. Finally got it inside $el.

so we need to replace this.$refs.infoBox.clientHeight; with this.$refs.infoBox.$el.clientHeight;

This just worked well for me.

Update

While using nuxt this.$refs.infoBox.$el.clientHeight; didn't work. but Ron C's answer works for this case. this.$refs.infoBox.$el.clientHeight; seems to work while using @vue/cli

FYI - had the issue accessing $el as well (had undefined). With vue/typescript - the following worked ok:

console.log('scriptPanel: mounted: sizes: ', (this.$refs.scriptSheet! as any).$el.clientHeight)
