I have two grids nested within a grid. Unfortunately the right nested grid .grid-3 sets the height of the rows so that both the left and right grid are the same

    You can also try grid-auto-rows: fit-content(1em);. Of course, use whatever sizing makes sense for you. I also tried the approach described by Temani (minmax(min-content, max-content)) and the results were identical when rendering my HTML.

    According to Elad Schechter - Medium,

    The fit-content function accepts one param, the maximum value. ... The fit-content() function is similar to using the minmax() function, with a minimum value of 0. One key difference: The minmax() is more likely to occupy the max space allowed, while the fit-content does not occupy any more space than necessary.

    Your needs will determine whether fit-content is more appropriate than using minmax and vice-versa.

    You can try minmax(min-content, max-content) ref 

    div {
  border: 1px dotted black;
}
.grid-2 {
  display: grid;
  grid-template-columns: repeat(2, 1fr);
  grid-auto-rows: minmax(min-content, max-content);
}

.grid-3 {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr;
  grid-auto-rows: minmax(min-content, max-content);
}

.left {
  background-color: red;
}
 
.right {
  background-color: green;
}
    <div class="grid-2">
      <div class="grid-2">
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
     </div>
     <div class="grid-3">
         <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
     </div>
</div>

    You can also use only max-content or min-content

    div {
  border: 1px dotted black;
}
.grid-2 {
  display: grid;
  grid-template-columns: repeat(2, 1fr);
  grid-auto-rows: max-content; /* min-content*/
}

.grid-3 {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr;
  grid-auto-rows: max-content; /* min-content*/
}

.left {
  background-color: red;
}
 
.right {
  background-color: green;
}
    <div class="grid-2">
      <div class="grid-2">
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
     </div>
     <div class="grid-3">
         <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
     </div>
</div>

    By default grid items stretch to all grid cell area. So you have this options here if you want grid's height to fit content:

    • Set alignment for all items using align-items for grid container (default value is align-items: stretch). So just set align-items: start for grid-2. Demo:

      div {
  border: 1px dotted black;
}

.grid-2 {
  display: grid;
  grid-template-columns: repeat(2, 1fr);
  align-items: start;
}

.grid-3 {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr;
}

.left {
  background-color: red;
}
 
.right {
  background-color: green;
}
      <div class="grid-2">
      <div class="grid-2">
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
     </div>
     <div class="grid-3">
         <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
     </div>
</div>

  align-self: start;
}

.left {
  background-color: red;
}
 
.right {
  background-color: green;
}
      <div class="grid-2">
      <div class="grid-2">
        <div class="left">L</div>
        <div class="left">L</div>

        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
     </div>
     <div class="grid-3">
         <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>

        <div class="right">R</div>
        <div class="right">R</div>
     </div>
</div>

    • Set alignment for grid items individually using margin property with auto values. Auto margins for grid cell take all available space in any direction. So just set margin-bottom: auto for grid-3. Demo:

      div {
  border: 1px dotted black;
}

.grid-2 {
  display: grid;
  grid-template-columns: repeat(2, 1fr);
}

.grid-3 {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr;
  margin-bottom: auto;
}

.left {
  background-color: red;
}
 
.right {
  background-color: green;
}
      <div class="grid-2">
      <div class="grid-2">
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
        <div class="left">L</div>
     </div>
     <div class="grid-3">
         <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
        <div class="right">R</div>
     </div>
</div>

    If you want right grid to take all parent vertical space but make its cells to fit content use this answer.
