aspect-ratio media feature

Defined as the ratio of value of the width media feature to the value of the height media feature.

Possible values

  • Value: <ratio>
  • Applies to: bitmap media types
  • Accepts min/max prefixes: yes


The Cascading Style Sheets (CSS) <ratio> type is defined in the Media Queries specification as a positive (not zero or negative) integer followed by optional whitespace, followed by a solidus ("/"), followed by optional whitespace, followed by a positive integer—for instance, "16/9".


The following declaration will apply "border:none" when the screen's aspect ratio is 91/50 (equivalent to 1.85, which is a common widescreen movie aspect ratio) or smaller.

@media screen and (max-aspect-ratio: 91/50) {
div { 
  border: none;
