| Platform | Post Type | Recommended Pixels | Aspect Ratio |

| YouTube | Video Thumbnail | 1280 × 720 px | 16:9 |
| YouTube | Channel Banner | 2560 × 1440 px (Safe: 1546×423) | 16:9 |
| TikTok | Video Cover & Post | 1080 × 1920 px | 9:16 |

Social media interfaces are dynamic. On TikTok and Instagram Reels, the bottom 25% of the screen is overlaid with creator captions, audio tags, and follow buttons, while the right side is filled with like, comment, and share icons.
Always maintain a 220-pixel safe buffer on the top, bottom, and right margins when placing titles, subtitles, or product logos. This guarantees that your core message is never obscured by mobile UI overlays.
The highest-engagement format on Instagram is Portrait (4:5 aspect ratio, 1080 x 1350 pixels). It occupies the maximum vertical screen space in the mobile feed, capturing user attention longer than square (1080 x 1080 px) or landscape (1080 x 566 px) formats.
While the total recommended banner size is 2560 x 1440 pixels (16:9), the safe zone for text and logos is the central 1546 x 423 pixel box. Anything placed outside this central area will be cropped on mobile devices and tablet screens.
Both TikTok videos and Instagram Reels use a 9:16 vertical aspect ratio at 1080 x 1920 pixels. Be sure to keep key text elements inside the safe zone (at least 220 pixels from the top and bottom) to avoid being obscured by profile usernames, captions, audio icons, and sidebar buttons.
For LinkedIn feed posts, 1200 x 1200 pixels (1:1) or 1080 x 1350 pixels (4:5) are ideal. For OpenGraph link preview cards, LinkedIn requires a 1.91:1 ratio at 1200 x 627 pixels.
Social platforms aggressively recompress images that exceed max dimension limits or have irregular aspect ratios. If you upload a 4000x3000 photo, the platform's automated compression will blur fine details. Sizing your image to exact platform dimensions (e.g. 1080x1350 for Instagram) before uploading ensures pristine clarity.
