Every social media platform has its own unique set of image dimension requirements, and these specifications change frequently as platforms redesign their interfaces and introduce new features. Using incorrectly sized images results in awkward cropping, unwanted letterboxing, blurry stretching, and an overall unprofessional appearance that undermines your brand credibility. Whether you are a social media manager handling multiple client accounts, a content creator building your personal brand, or a business owner trying to maintain a professional online presence, knowing the exact image dimensions for each platform is absolutely essential.
In this comprehensive guide, we will cover the exact pixel dimensions for every major image placement on Instagram, YouTube, Facebook, LinkedIn, Twitter/X, TikTok, and Pinterest — all updated for 2026. We will also show you how to use MyImgToolsPro's free Social Media Resizer to instantly format your images for any platform with a single click.
Instagram Image Sizes (2026)
Instagram remains one of the most visually demanding platforms, with strict expectations for image quality and dimensions. Here are all the current size specifications:
Square Post: 1080 x 1080 pixels (1:1 aspect ratio). This is the classic Instagram format and still the most commonly used. It looks consistent in the feed grid and provides a large, impactful canvas for product photos and lifestyle imagery.
Portrait Post: 1080 x 1350 pixels (4:5 aspect ratio). This vertical format takes up more screen real estate in the feed than a square post, making it ideal for catching attention while scrolling. It is now the recommended format for maximum engagement.
Landscape Post: 1080 x 566 pixels (1.91:1 aspect ratio). While less common, landscape format is useful for panoramic shots and cinematic compositions. Be aware that it appears smaller in the feed grid compared to square and portrait formats.
Story / Reel: 1080 x 1920 pixels (9:16 aspect ratio). Full-screen vertical format used for Instagram Stories and Reels. This is a critical dimension, as Stories and Reels are now among the most viewed content types on the platform.
Profile Picture: 320 x 320 pixels (1:1 aspect ratio). Displayed as a small circle on your profile page and next to your posts. Upload at 320x320 minimum for sharp rendering on all devices, including retina displays.
YouTube Image Sizes (2026)
Channel Banner: 2560 x 1440 pixels. This is the large header image at the top of your channel page. The safe area (visible on all devices) is 1546 x 423 pixels in the center, so keep important text and logos within this zone.
Video Thumbnail: 1280 x 720 pixels (16:9 aspect ratio). Thumbnails are arguably the most important visual element on YouTube — they directly influence click-through rates and video performance. Use bold text, bright colors, and clear subject faces for maximum impact.
Profile Picture: 800 x 800 pixels (1:1 aspect ratio). Displayed next to your videos and comments. Keep it simple and recognizable at small sizes — a face close-up or a bold logo works best.
Facebook Image Sizes (2026)
Cover Photo: 820 x 312 pixels (desktop) / 640 x 360 pixels (mobile). Facebook displays the cover photo at different crops on desktop and mobile, so keep important content centered.
Post Image: 1200 x 630 pixels (1.91:1 aspect ratio). This is the recommended size for link previews and shared images. It renders consistently across both mobile and desktop feeds.
Profile Picture: 170 x 170 pixels (desktop) / 128 x 128 pixels (mobile). Displayed as a circle. Upload at 512x512 minimum for crisp rendering.
Event Cover: 1920 x 1005 pixels. Used for Facebook Events and displays prominently at the top of the event page.
LinkedIn Image Sizes (2026)
Profile Banner: 1584 x 396 pixels. The professional equivalent of a Facebook cover photo. Use it to showcase your expertise, company branding, or portfolio highlights.
Post Image: 1200 x 627 pixels for horizontal images, 1080 x 1080 for square images. LinkedIn's algorithm tends to favor posts with images over text-only posts, so always include a visual.
Profile Photo: 400 x 400 pixels (1:1 aspect ratio). Cropped to a circle. Professional headshots perform best on LinkedIn.
Twitter/X Image Sizes (2026)
In-Stream Photo: 1600 x 900 pixels (16:9 aspect ratio). This dimension ensures your image displays fully in the timeline without being cropped.
Header Photo: 1500 x 500 pixels (3:1 aspect ratio). The banner at the top of your profile page.
Profile Photo: 400 x 400 pixels. Cropped to a circle on the platform.
