4x5 Video Dimensions: Complete 2026 Guide (Resolution, Specs, Examples)
If you're producing video for Instagram, Facebook, or LinkedIn in 2026, the 4x5 aspect ratio is the format to know. It's the highest-engagement format on those platforms — it fills more vertical space than a square post but stays inside the feed without going full-screen, which keeps viewers from scrolling away. This guide covers the exact 4x5 resolution specs, when to use it vs. other ratios, and how to produce 4x5 video without filming in portrait mode.
Quick Reference: 4x5 Video Specs

|---|---|
| Aspect ratio | 4:5 (width:height) |
| Standard 4x5 resolution | 1080 × 1350 px |
| HD 4x5 resolution | 1440 × 1800 px |
| 4K 4x5 resolution | 2160 × 2700 px |
| Frame rate | 24, 30, or 60 fps |
| Codec | H.264 (MP4) |
| Best platforms | Instagram feed, Facebook feed, LinkedIn, Pinterest |
| Max length (Instagram feed) | 60 minutes |
| Max length (Facebook feed) | 240 minutes |
What Is 4x5 Aspect Ratio?
A 4x5 aspect ratio is a near-square portrait format where the video's width is 4 units for every 5 units of height. Render it at the standard 4x5 resolution of 1080×1350 pixels and you get the highest-engaging format Instagram supports for in-feed video.
It's *not* the same as 9:16 (TikTok / Reels / Stories) or 1:1 (classic Instagram square). 9:16 is taller and meant for full-screen mobile experiences. 1:1 is the legacy Instagram format. 4:5 is the sweet spot — taller than 1:1, less aggressive than 9:16, and best-performing for feed-based discovery.
4x5 Resolution in Pixels: The Common Sizes
There's no single "correct" 4x5 resolution — it's about the ratio. But these are the sizes you'll actually use:
- 1080 × 1350 — the standard. What Instagram, Facebook, and LinkedIn expect for feed video. Use this 90% of the time.
- 1440 × 1800 — HD upscale. Good if you're producing for ads where higher fidelity matters.
- 2160 × 2700 — 4K equivalent. Future-proof for archival; most platforms downsample anyway.
- 864 × 1080 — small / draft. Avoid for production, useful for previews.
If your editor exports a slightly different resolution (e.g., 1080×1349) due to rounding, that's fine — feed platforms tolerate ±2 pixels.
Why 4x5 Wins on Mobile-First Platforms
Three reasons 4:5 outperforms other ratios in 2026:
- Feed-screen coverage. A 4:5 video occupies roughly 78% of a typical phone screen in-feed. A 1:1 square covers ~62%. More screen = more dwell time.
- No full-screen takeover. Unlike 9:16, 4:5 doesn't trigger "swipe to dismiss" — viewers can engage with one hand while still seeing the like and comment buttons.
- Cross-platform portability. A 4:5 video runs cleanly on Instagram, Facebook, LinkedIn, Pinterest, and even Twitter/X. 9:16 only works for Reels-type placements.
� Hootsuite's 2026 Social Media Benchmark Report found 4:5 feed videos generated 32% more average watch time than 1:1 and 17% more than 16:9 letterboxed feed posts.
4:5 vs. Other Common Aspect Ratios
| Aspect Ratio | Resolution | Best Use | Engagement Floor |
|---|---|---|---|
| 16:9 | 1920×1080 | YouTube, TV, desktop video | Low on mobile feeds (letterboxes) |
| 9:16 | 1080×1920 | TikTok, Reels, Stories | High but full-screen-only |
| 1:1 | 1080×1080 | Legacy Instagram, ads | Medium — being phased out |
| 4:5 | 1080×1350 | Instagram feed, Facebook feed, LinkedIn | Highest for feed-based discovery |

TikTok (Cross-Posted)
TikTok prefers 9:16, but 4:5 *displays* with subtle vertical bars. Acceptable for cross-posting; not optimal as a primary format.
How to Create 4x5 Videos Without Filming in Portrait Mode
If you're already producing 16:9 content, you have three paths to 4:5:
- Reframe + crop — center your subject, crop to 1080×1350. Loses width.
- Generative fill — let an AI model fill the additional vertical space using context from the surrounding pixels. Modern editors (Premiere, DaVinci, Descript) ship this.
- Re-shoot in vertical — best quality, highest cost.
Or, skip the cropping problem entirely with AI avatar videos — Percify outputs natively in any aspect ratio you specify, including 4:5. No cropping, no generative fill, no quality loss.
Creating 4x5 Videos with Percify
Percify generates 4x5 video at 1080×1350 natively from a text prompt or script. The full workflow:
- Pick or upload an avatar. Use a stock avatar or clone yourself from a 60-second sample.
- Paste your script. Or generate one with the built-in prompt-to-script flow.
- Set output as 4:5 (1080×1350). Aspect ratio is a single dropdown.
- Render. Returns in 2-5 minutes for a 60-second clip.
- Caption + post. The output already includes burn-in subtitles if you enable them.
You skip the entire "shoot widescreen, crop to 4:5" loop. The avatar is framed for vertical from the start.
See the text-to-avatar guide for the full workflow, or compare against other AI video tools before deciding.
Common 4x5 Video Mistakes
- Cropping a widescreen subject without reframing. You'll cut off heads, hands, and product details. Always reframe before cropping.
- Burning in captions outside the safe zone. The bottom 250px of a 4:5 video gets covered by Instagram UI elements. Keep text in the middle 80% vertically.
- Mismatched cover frame. The first frame becomes the static thumbnail in feed. Pick a strong visual; don't let it auto-default to frame 0.
- Exporting at the wrong frame rate. 24 fps looks cinematic but stutters on aggressive scroll. 30 fps is the safe default for feed video.
- Forgetting LinkedIn captions. Default-mute means a captionless video gets ignored.

Conclusion
The 4x5 aspect ratio at 1080×1350 resolution is the highest-leverage video format for Instagram, Facebook, and LinkedIn feeds in 2026 — and the gap will likely widen as feed algorithms keep rewarding screen coverage.

Frequently asked
4x5 aspect ratio is a near-square portrait format where the video's width is 4 units for every 5 units of height. Rendered at the standard 4x5 resolution of 1080×1350 pixels, it's the highest-engaging video format on Instagram, Facebook, and LinkedIn feeds because it covers more vertical screen space without triggering full-screen takeover.
The standard 4x5 video resolution is 1080×1350 pixels. HD upscale is 1440×1800 pixels, and 4K is 2160×2700 pixels. All three preserve the 4:5 aspect ratio. Use 1080×1350 for 90% of cases — it's what Instagram, Facebook, and LinkedIn expect for feed video.
Yes — 1080×1350 is the standard pixel resolution for the 4:5 aspect ratio. The two terms are used interchangeably. If a platform spec calls for '1080×1350 video,' you're being asked for 4:5.
Yes — Instagram supports 4x5 video at 1080×1350 in the main feed (up to 60 minutes long, 4 GB file size). 4x5 is actually Instagram's recommended format for in-feed video because it covers more screen than 1:1 square posts. For Stories and Reels, use 9:16 (1080×1920) instead.
4x5 (1080×1350) is taller than 1:1 (1080×1080) and covers about 25% more vertical screen space in feed. That extra coverage typically translates to ~30% more average watch time, which is why 4:5 has largely replaced 1:1 as the preferred Instagram and LinkedIn feed format. Use 1:1 only when posting to platforms that explicitly require it (older Twitter/X embeds, some ad placements).
9:16 (1080×1920) is full vertical — designed for Stories, Reels, and TikTok where the video takes over the full screen. 4:5 (1080×1350) sits inside the feed, leaving room for captions, like buttons, and comment counts. Use 9:16 for full-screen mobile experiences and 4:5 for feed-discovery content.
Three options: (1) reframe and crop your existing 16:9 footage to 1080×1350, (2) use generative AI fill in modern editors like Premiere or DaVinci Resolve to extend vertical space, or (3) generate native 4x5 video with an AI avatar tool like Percify, which renders directly at 1080×1350 from a text prompt — no cropping or quality loss.
30 fps is the safe default for feed video — it looks smooth during fast scroll. 24 fps gives a more cinematic feel but can stutter on aggressive scroll behavior. 60 fps is overkill for feed content and increases file size without meaningful engagement gain.
