What size is an Instagram Reel?

Instagram Reels are 1080 × 1920 pixels, a 9:16 vertical aspect ratio, the same as TikTok and YouTube Shorts. Export at 1080 × 1920 and keep your key action centred, since the caption and action buttons cover the lower third and Reels are cropped to roughly 4:5 in the feed grid.

What are Instagram Story dimensions?

Stories are also 1080 × 1920 (9:16). The important part is the safe zone: keep text and logos clear of the top ~250 px (your profile and the close button) and the bottom ~250 px (the reply bar and any link sticker), so nothing important gets covered.

What is the best size for an Instagram feed post?

Portrait 4:5 at 1080 × 1350 is the best-performing feed size; it takes the most vertical space as people scroll. Square 1:1 at 1080 × 1080 is the safe all-rounder and reads consistently in the grid and in carousels. The maximum width Instagram displays is 1080 px either way.

Should Instagram posts be square or portrait?

Portrait (4:5) for reach: a taller post occupies more of the screen and stops the scroll. Square (1:1) for consistency: it crops predictably in the profile grid and is the safest choice for carousels where every slide must share one ratio.

How long can an Instagram Reel be?

A Reel uploaded from your camera roll can run up to 3 minutes, which is the reliable limit to stay a true Reel. In-app recording offers 15, 30, 60 and 90-second options. Longer uploads exist but aren’t prioritised the same way, so 3 minutes is the safe ceiling.

What size should an Instagram carousel be?

Use 1080 × 1350 (4:5) or 1080 × 1080 (1:1), and size every slide to the same ratio. Instagram forces all slides to match the aspect ratio of the first slide, so a mismatched slide gets cropped. Pick one ratio up front and export each image and video to it.

Reels, Stories and feed posts: the resolution, aspect ratio, length and safe zone for every Instagram format.

9:16

App UI covers the shaded edges. Keep content inside the dashed area.

Resolution: 1080 × 1920
Aspect ratio: 9:16
Max duration: Up to 3 minutes
Max file size: ~650 MB (Reels under 10 min)
File types: MP4, MOV (H.264 / AAC)
Frame rate: 30 fps recommended (up to 60)

The caption, audio ticker and action buttons crowd the bottom and right. Reels also appear cropped to ~4:5 in the feed grid, so keep the key action centered. (Some uploads run longer than 3 min, but 3 min is the reliable Reel limit.)

Resolutions and aspect ratios are stable; durations, file-size limits, crops and safe-zone margins reflect the major social platforms as of June 2026 and shift over time. Confirm in-app before a high-stakes upload.
