Hi @Pakistanpowerto
Firstly, you should check the theme settings or section settings to find setting image ratio.
Or You can try follow this path:
Themes => edit code => asset => base.css
and add this code to bottom of the file base.css

.collection-list .card__inner {
  --ratio-percent: 100% !important;
}
