Practical Tips
- Keep key text centered with generous side margins to survive responsive cropping.
- Export distinct OG and Twitter card variants if you need precise presentation.
- Preview share cards with platform validators before major launches.
For cross-device and cross-platform delivery, define primary and secondary aspect ratios before design production begins. This avoids rushed crops and improves visual consistency in real-world usage.
A ratio-first workflow also helps engineering and content teams align early, especially when assets must support both app UI and marketing surfaces.
