What is an Aspect Ratio?

An aspect ratio describes the proportional relationship between width and height. It's expressed as two numbers separated by a colon (e.g., 16:9), where the first number represents width and the second represents height.

Why Does It Matter?

Maintaining aspect ratio prevents images and videos from appearing stretched or squished. It's crucial for responsive design, ensuring content looks correct across different screen sizes.

CSS aspect-ratio Property

Modern CSS supports the aspect-ratio property, making it easy to maintain proportions:

.video-container {
  aspect-ratio: 16 / 9;
  width: 100%;
}

Responsive Images

Use aspect ratio with object-fit for responsive images that maintain their proportions:

.image-container {
  aspect-ratio: 4 / 3;
}
.image-container img {
  object-fit: cover;
  width: 100%;
  height: 100%;
}
