X image size guide
Keeping 2–4 images at the same aspect ratio makes it easier to check their framing. These are starting points for image creation, not a guarantee of the area X will display.
| Use and image count | Aspect ratio | Size example |
|---|---|---|
| Detail + full image (2 images) | 3:4 | 960×1280px |
| Vertical sections (2–4 images) | 3:4 | 960×1280px |
| Connected wide images (2–4 images, separate tool) | 4:5 / 1:1 | 1080×1350px / 1200×1200px |
| Original four-part split (4 images) | 16:9 (default crop setting) | Up to 1920×1080px |
Start with 3:4, 4:5, or 1:1 when checking for cropping. For four original-format 16:9 images, 1920×4320px is a useful source size; gap compensation requires extra height. Split full image mode uses an aspect ratio based on the source.
What happened to four-image grids on X?
A carousel layout for multiple images was announced for iOS in July 2026, with browser rollout reported in August. In a carousel, viewers move horizontally between images. Four vertically stacked sections, 2×2 image grids, and hidden-picture tricks based on the former cropped grid no longer produce the same effect in this layout.
This page offers a cropped detail plus a full-image overview, as well as vertical sections to read from top to bottom. To connect a wide image horizontally, use the Instagram & X Image Splitter.

If your images are cropped
Testing reports suggest that mixed aspect ratios, the first two images, and their order can affect the visible area. Start with matching ratios, keep important text and faces away from the edges, and check the images in X’s post composer. A 16:9 image may lose its sides; a 9:16 image may lose its top and bottom. App and browser views may differ.

FAQ
The original vertical split and gap effect
In the former X layout, four 16:9 images could be stacked to make a tall photo or illustration look like one picture. Skipping small portions of the source to account for the black or white gaps helped align lines across the panels, like a view through window frames.
Original four-part split keeps the crop, zoom, position, and gap-compensation controls. A carousel does not recreate the former vertically connected picture or gap effect.
