Instagram Stories video dimensions in 2026: 1080×1920 (9:16) native. Full list of supported aspects, pixel sizes, and common upload mistakes.
Instagram Stories video dimensions: 1080×1920 (9:16 aspect ratio).
The recommended Instagram Stories video dimensions in 2026 are 1080×1920 in a 9:16 aspect ratio. This is the resolution the feed renders at natively — uploading at a smaller size triggers an upscale and visible softness; uploading larger gets downscaled, costing you sharp text.
Instagram Stories supports 9:16 (1080×1920). The platform's encoder re-transcodes anything you upload, so shipping at the native ratio is the single biggest lever for retaining quality. Bitrate matters less than ratio — match the ratio and the algorithm doesn't have to letterbox or center-crop.
Common mistakes creators make on Instagram Stories: (1) exporting at 1280×720 instead of full HD — works, but you lose half the pixel density on retina phones. (2) Letterboxing a 16:9 clip into a 9:16 frame with black bars — the algorithm reads the dead zones as low-quality content and suppresses reach. (3) Burning in captions in the wrong safe-zone for Instagram Stories — UI chrome differs per platform, so a caption that's clear on TikTok can be obscured by Instagram Stories's overlay.
If you're repurposing from another platform, convert the aspect ratio first. A common conversion path is reframing a 16:9 long-form clip into a 9:16 short by using smart-crop (subject tracking) rather than naive center-crop. Note: auto-splits videos longer than 60s into chained 60s segments.
The comparison table below shows the recommended video dimensions across the platforms most creators publish to alongside Instagram Stories.

| TikTok | 1080×1920 | video-short |
1080×1920 (9:16) is the native resolution. Instagram Stories accepts 9:16 (1080×1920) but renders best at the primary ratio.
Yes — Instagram Stories will accept higher-resolution uploads, but the player tops out at 1080×1920 on most devices, so you're paying upload bandwidth for pixels the viewer never sees.
Instagram Stories either letterboxes (black bars) or center-crops. Both reduce reach because the algorithm reads the dead space or the cut-off subject as low-quality content.
No. Instagram Stories doesn't support re-uploading a different version under the same post. Delete and re-publish if you must change ratio.
9:16 is the native frame. If you're cross-posting, render the master at 9:16 and convert outward — converting toward 9:16 from another ratio always loses pixels.
