We’ve improved the logic for determining media aspect ratios (Image Ratio = Original) in our Social widgets 
-
Single source — the widget uses the platform’s native ratio.
-
Mixed sources — defaults to 1x1. However, if multiple vertical platforms with different ratios are combined (e.g., Instagram 4x5 + TikTok 9x16), the least vertical ratio is used instead of 1x1.
-
Masonry/Popup view — the actual image dimensions are used.
Platform Aspect Ratios:
- Instagram – 4x5
- TikTok – 9x16
- YouTube – 16x9
- Vimeo – 16x9
- Facebook – 1x1
- Twitter – 1x1
- Pinterest – 2x3
- LinkedIn – 1x1
- Tumblr – 1x1
- RSS – 16x9
