Social media platforms resize and re-compress every image you upload. If you upload at the exact dimensions they expect, the platform applies minimal processing and your image stays sharp. Upload something too large or the wrong aspect ratio, and the platform will crop it unpredictably and compress it aggressively.
This guide covers the recommended image sizes for every major platform in 2026, with links to free tools that resize to each platform's exact requirements.
Instagram Image Sizes
Instagram is the most dimension-sensitive platform. It automatically crops images that don't match its supported aspect ratios, and it compresses heavily — uploading at exact dimensions minimizes quality loss.
- Square post: 1080 × 1080 px (1:1)
- Portrait post: 1080 × 1350 px (4:5) — takes up the most feed space, best for engagement
- Landscape post: 1080 × 566 px (1.91:1)
- Story / Reel: 1080 × 1920 px (9:16 full screen)
- Profile photo: 320 × 320 px (displays at 110 px circle)
Pro tip: Always upload at 1080px wide. Instagram downscales anything wider, but if you upload narrower, it upscales and you lose sharpness.

Facebook Image Sizes
Facebook supports a wide range of image sizes but displays them at specific dimensions in the feed. Uploading at the recommended sizes avoids re-compression artifacts.
- Feed post: 1200 × 630 px (1.91:1) — optimal for link previews and shared posts
- Square post: 1080 × 1080 px (1:1)
- Cover photo: 820 × 312 px (desktop) / 640 × 360 px (mobile) — upload at 820 × 462 px to cover both
- Profile photo: 170 × 170 px (displays as circle)
- Event cover: 1200 × 628 px
- Group cover: 1640 × 856 px
Resize for Facebook — get pixel-perfect dimensions for every Facebook image type.
Twitter/X Image Sizes
Twitter/X crops images in the feed to a 16:9 aspect ratio. If your image isn't 16:9, the platform decides what to crop — and it doesn't always choose well.
- In-feed image: 1200 × 675 px (16:9) — displays without cropping
- Two images: 700 × 800 px each (7:8)
- Header/banner: 1500 × 500 px (3:1)
- Profile photo: 400 × 400 px (displays as circle)
Pro tip: For single-image tweets, 1200 × 675 is the sweet spot. The entire image shows in the feed without being cropped, and the file stays under Twitter's 5MB limit for photos.

LinkedIn Image Sizes
LinkedIn is increasingly visual, and properly sized images get significantly more engagement than poorly formatted ones.
- Feed post: 1200 × 627 px (1.91:1) or 1080 × 1080 px (1:1 square)
- Article cover: 1200 × 644 px
- Company banner: 1128 × 191 px
- Personal banner: 1584 × 396 px
- Profile photo: 400 × 400 px (displays as circle)
- Company logo: 300 × 300 px

YouTube Image Sizes
YouTube thumbnails are critical for click-through rate — a compelling thumbnail at the right size can double your views.
- Thumbnail: 1280 × 720 px (16:9) — minimum 640px wide, under 2MB
- Channel banner: 2560 × 1440 px (upload size) — safe area is 1546 × 423 px (center)
- Channel profile: 800 × 800 px (displays at 98 px circle)
- Video watermark: 150 × 150 px (PNG with transparency)
Pro tip: YouTube's channel banner displays differently on TV, desktop, and mobile. The safe area (the part visible on all devices) is only the center 1546 × 423 pixels of the full 2560 × 1440 image. Keep important text and logos within the safe zone.
Resize for YouTube — create perfectly sized thumbnails and channel art.
WhatsApp Image Sizes
WhatsApp compresses images aggressively when sent as regular photos. Uploading at the recommended size minimizes additional compression.
- Profile photo (DP): 500 × 500 px (displays as circle, 192 × 192 px)
- Status image: 1080 × 1920 px (9:16, same as Instagram Stories)
- Shared image: maximum 1600 × 1200 px — anything larger is resized down and compressed further
Pro tip: To share full-quality images on WhatsApp without compression, send them as documents instead of photos. The file is delivered without any re-compression.
