Social Media Image Sizes: The Complete 2026 Cheat Sheet
Every platform crops, compresses and reformats your images differently, and an image that looks sharp on one network turns into a blurry, badly-cropped mess on another. This cheat sheet collects the sizes that matter in 2026, and explains the two or three rules that prevent 90% of quality problems.
Feed posts: 1080×1080 (square), 1080×1350 (portrait 4:5 — takes the most screen space and usually performs best), 1080×566 (landscape). Stories and Reels: 1080×1920 (9:16). Keep text and faces inside the central "safe zone", because the interface overlays the top and bottom ~250 pixels. Profile picture: 320×320, displayed as a circle — keep the subject centered.
Shared link / post image: 1200×630 — the same size as the Open Graph image, so one file covers both your website previews and your Facebook posts. Cover photo: 820×312 on desktop, but it crops to roughly 640×360 on mobile, so keep critical content in the center. Event cover: 1920×1005. Profile: 170×170 (rendered from a larger upload; use at least 320×320).
YouTube
Thumbnails: 1280×720, under 2 MB. This is the single highest-impact image on the platform — it largely determines your click-through rate. Use high contrast and text readable at small sizes: most people see your thumbnail at roughly 320 pixels wide. Channel art: 2560×1440, with the "safe area" for text at 1546×423 in the center (TVs see everything, phones only see the middle strip). Profile: 800×800.
Post images: 1200×627. Profile photo: 400×400 minimum. Personal banner: 1584×396. Company logo: 300×300. LinkedIn compresses aggressively, so upload PNGs for anything containing text or logos.
X (Twitter)
In-feed images: 1600×900 (16:9) displays without cropping. Header: 1500×500 — note that the profile picture overlaps the bottom-left corner. Profile: 400×400.
Three rules that prevent most quality problems
1. Always downscale, never upscale. Making an image smaller keeps it sharp; stretching a small image larger creates blur that no platform will fix. Export from your design tool at 2× the target size when you can.
2. Resize to the exact dimensions before uploading. When you let the platform crop for you, it decides what gets cut — usually badly. Our free image resizer includes one-click presets for the sizes above and keeps the aspect ratio locked so nothing gets distorted, all processed locally in your browser.
3. Compress before the platform does. Every network re-compresses your upload. Feeding it an already-optimized image (JPEG/WEBP at 80–90% quality, done with a compressor you control) gives its algorithm clean source data and produces visibly better results than uploading a raw 8 MB photo.
One workflow for all platforms
Design once at high resolution (e.g. 2160×2160 for a square campaign visual), then batch-resize to each platform's dimensions and batch-compress the results. With browser-based tools this takes about a minute for a full campaign, nothing gets uploaded to third-party servers, and every network receives an image at its native size.
