Instagram Post Size & Dimensions Guide 2026

Every Instagram image and video size in one place — updated for 2026. Use these exact dimensions to avoid cropping, blurry uploads, and algorithm penalties for low-resolution content.

Most Important

Reels

The primary growth format on Instagram. Always film in portrait — this is what fills the phone screen edge to edge.

⚠️ Keep important content away from the top 250px and bottom 400px — the caption, buttons, and profile info overlay these areas on mobile.

Feed Photo

Square, Portrait & Landscape

Instagram supports multiple aspect ratios for feed photos. Portrait (4:5) takes up the most screen space and generally gets more engagement.

Stories

Instagram Stories

Same dimensions as Reels. Stories disappear after 24 hours unless saved to Highlights. Supports photos and videos.

Carousel Posts

Carousel / Album Posts

Carousels are experiencing a major comeback in 2026 — they drive the highest save rates and can go viral days after posting. Use the same dimensions as feed photos.

RECOMMENDED SIZE

MAX SLIDES

MIX TYPES

Tip: Keep all slides the same aspect ratio. Mixing portrait and landscape in one carousel causes inconsistent cropping.

Profile

Profile Picture

Displayed at 110×110 px on mobile but stored at higher resolution. Always upload the largest version available for crisp display on high-resolution screens.

Why Correct Dimensions Matter

Uploading content at the wrong size doesn't just look bad — it can hurt your performance. Instagram re-compresses videos and images that don't match its preferred dimensions, which reduces quality. Low-quality content gets pushed less by the algorithm.

For Reels specifically, the 9:16 format fills the entire phone screen — there's no wasted space, no black bars, nothing to distract from your content. Landscape or square reels show with black bars on mobile, which signals to viewers (and the algorithm) that the content wasn't made for the platform.

Always film and edit natively in the format you're posting. Cropping after the fact loses quality. Tools like CapCut, InShot, and Adobe Premiere Pro all have preset templates for every Instagram format.
