Instagram Image Sizes and Specs (2026): Feed, Reels, Stories & Cross-Platform

Why Instagram image sizes still decide perceived quality

Instagram compresses and crops aggressively. If you upload the wrong aspect ratio, the platform decides what to cut — often faces, product labels, or text. Correct Instagram image sizes keep your subject inside the frame and reduce secondary quality loss.

Design for phones first. Most followers never see your desktop mockup. Preview every export on a small screen before publishing. Over 80% of social browsing happens on phones; a size that looks fine on a laptop can fail on a commute screen.

This guide is the canonical size chart for SocialTools Online. It covers Instagram in depth, then the other platforms you cross-post to, so you do not maintain two overlapping articles for the same intent.

What are the Instagram image sizes for feed, Reels, and Stories?

Portrait feed: 1080×1350 px (4:5) — usually the best use of feed real estate. Square: 1080×1080 px (1:1). Landscape feed is allowed but offers less vertical space. Profile photo displays small; upload at least 400×400 px (sharper when higher).

Carousels should keep a consistent ratio across slides. Slide one needs a clear promise; the final slide should carry the CTA. Margins should stay consistent so swipes feel intentional.

Reels and Stories: 1080×1920 px (9:16). Keep logos, faces, and captions away from the top and bottom edges where username, stickers, and buttons sit. Critical action should live in the center 70–80% of the frame. Cover frames compete as tiny grid thumbnails and as full-screen first frames — test readability at both scales.

Instagram size chart (quick reference)

Feed portrait (recommended): 1080×1350 (4:5). Feed square: 1080×1080 (1:1). Stories / Reels: 1080×1920 (9:16). Profile photo: upload ≥400×400 (displays ~320×320). Safe zone for vertical video: keep critical content in the center ~70–80% of the frame.

Export at these pixel sizes before upload rather than stretching inside Instagram. Stretching invites soft edges and unexpected crops when the app recompresses.

TikTok and YouTube sizes when you cross-post

TikTok video and cover: 1080×1920 px (9:16) — the same canvas as Instagram Reels, which is why a single vertical master often works for both if you leave safe margins.

YouTube thumbnail: 1280×720 px (16:9), minimum width 640 px. YouTube channel banner: 2560×1440 px with a safe text area roughly 1546×423 px on desktop. Thumbnails compete in search — high contrast, 3–5 words max, faces when relevant, readable at phone size.

If you strip Instagram UI chrome and foreign watermarks before posting to TikTok or Shorts, retention improves. Confirm 9:16 after any crop.

X, Facebook, and LinkedIn image dimensions

X (Twitter) in-stream image: 1600×900 px (16:9) or 1200×675 px. Facebook feed link/image: 1200×630 px. LinkedIn post image: 1200×627 px. LinkedIn article cover: 1920×1080 px.

LinkedIn audiences tolerate longer text on images than Instagram. Keep B2B graphics clean and legible — avoid cluttered infographics on mobile. Open Graph style 1200×630 assets also double as trustworthy link previews when you send bio traffic to a blog.

File type, compression, and a privacy-first export workflow

Photos usually prefer JPEG or WebP; graphics with text or sharp edges may prefer PNG. Resize to target dimensions before upload. Compress heavy files when mobile uploads fail. Avoid re-saving screenshots multiple times — quality degrades quickly.

Recommended workflow: pick the ratio → design/shoot → resize in a privacy-first browser tool → verify dimensions → upload. SocialTools image tools process files locally when the tool supports it, so drafts do not need a cloud DAM account.

Batch weeks: lock settings on one “golden” asset (feed 4:5 or Reels 9:16), then repeat the same export path for visual consistency across the calendar.

Common sizing mistakes (and how to avoid them)

Stretching images to fill, designing only at 1080×1080 when you care about feed presence, placing CTAs under UI chrome, and upscaling tiny screenshots until they pixelate.

Another failure mode: maintaining two nearly identical “image sizes” articles that split the same search intent. Use this page as the single size-chart reference, then link out to the image resizer and aspect ratio calculator to execute.
