Threads carousel size
1080 × 1350px
Aspect ratio
4:5
Make every Threads carousel item 1080 × 1350 px (4:5) — up to 20 photos or videos display as a swipeable strip at uniform height.
Last verified June 2026
Threads carousels attach up to 20 photos or videos to a single post — the platform announced the raise from 10 in late 2024 — and display them as a horizontally swipeable strip. The display rule that shapes the design: every item renders at the same height, so mixed aspect ratios produce a ragged row of different widths. Exporting the whole set at 1080 × 1350 px (4:5) keeps the strip uniform and each frame as tall as the feed allows.

| Square items | 1080 × 1080 px | 1:1 |
| Mixed ratios | anyAllowed — items scale to one shared height, so widths vary and the strip looks uneven. | varies |

The first one or two items show in the feed with the next frame peeking at the edge — that peek crops the following item’s left side, so don’t put critical content on the far left of frames 2+. Within each frame, keep text inside the central 85%: the strip’s rounded corners and tight gutters make edge-hugging type feel cramped, especially on smaller phones.
Twenty slots invite photo dumps, but the carousels that travel on Threads are sequences with a spine: a build process, a ranked list, a step-by-step, a then-vs-now. Put the hook frame first (it’s the one the feed shows), one idea per frame after, and a final frame that asks for a reply — Threads’ ranking rewards the conversation more than the swipe.
Because the strip normalizes height, a landscape chart between two portrait photos shrinks to a small wide tile and breaks the rhythm. If a sequence genuinely needs both orientations, pad the landscape items onto a 4:5 canvas with generous margins so every tile occupies the same footprint.
Instagram carousel exports fit Threads pixel-for-pixel, but the culture differs: Threads audiences respond to looser, more conversational sets than Instagram’s designed slides. Consider posting the same frames with a more candid caption, or trimming a 10-slide design piece down to the 4–5 frames that carry the argument.
Up to 20 photos or videos per post, mixed freely — Threads raised the limit from 10 in late 2024. They display as a horizontally swipeable strip.
1080 × 1350 px (4:5) for every item. All items render at one shared height, so a uniform ratio keeps the strip even; mixed ratios produce tiles of differing widths.
Yes — photos and videos sit side by side in the same strip. Export the videos at the same 4:5 ratio as the images so playback tiles match the rest of the set.
