<p><strong><code>Element.scrollHeight</code></strong> 읽기 전용 속성은 요소 콘텐츠의 총 높이를 나타내며, 바깥으로 넘쳐서 보이지 않는 콘텐츠도 포함합니다.</p>
<p><code>scrollHeight</code> 값은 수직 스크롤바를 사용하지 않고 요소의 콘텐츠를 모두 나타낼 때 필요한 최소 높이의 값과 동일합니다. 높이 측정은 {{domxref("Element.clientHeight", "clientHeight")}}와 동일한 방법을 사용하여 요소의 안쪽 여백은 포함하고, 테두리와 바깥 여백, (존재하는 경우) 수평 스크롤바의 높이는 포함하지 않습니다. 또한 {{cssxref("::before")}}, {{cssxref("::after")}} 등 의사 요소의 높이도 결과에 포함합니다. 요소의 콘텐츠를 수직 스크롤바 없이 모두 보일 수 있는 경우의 <code>scrollHeight</code>는 <code>clientHeight</code>와 동일합니다.</p>
<div class="note">
<p><code>scrollHeight</code>의 반환 값은 정수로 반올림됩니다. 소수점을 포함한 값이 필요한 경우 {{domxref("Element.getBoundingClientRect()")}}를 사용하세요.</p>
