| X post, landscape | 1600 x 900 | 16:9. Inside the 2:1 to 3:4 range X shows in full. |

| LinkedIn profile background | 1584 x 396 | 4:1. Your profile photo overlaps part of it, so keep anything important away from the lower left. |

X's help centre says images with aspect ratios between 2:1 and 3:4 display in full in the timeline. LinkedIn doesn't publish one required size for post images; the sizes above match the shapes it displays. Profile and header images are cropped differently on phones and desktops, so keep faces and text near the centre.
Your image is drawn on a canvas in this page and saved straight to your device. It's never uploaded.
