Social Media Image Sizes Guide 2025: Dimensions for Every Platform

Last month, I spent two hours creating the perfect promotional graphic for a client's new product launch—beautifully designed, text perfectly positioned, colors on-brand. Uploaded it to Instagram, and... the platform cropped off the top and bottom, cutting through the headline and call-to-action button. The post looked amateurish, the client was frustrated, and I had to redo everything from scratch. All because I used 1920×1080 (standard HD video dimensions) instead of Instagram's 1080×1080 square format. That painful lesson taught me something: in social media, getting dimensions wrong isn't a minor mistake—it's the difference between professional content and something that screams "I don't know what I'm doing."

Each social platform has specific size requirements, aspect ratios, and safe zones. Use the wrong dimensions, and your carefully crafted images get butchered by automatic cropping. Text gets cut off, faces disappear, important details vanish. This guide provides the exact, current specifications for every major platform—Facebook, Instagram, Twitter/X, LinkedIn, YouTube, Pinterest, TikTok—plus design tips to ensure your content looks perfect everywhere you post it. Whether you're a social media manager, small business owner, content creator, or just tired of your posts looking bad, these specifications will save you hours of frustration and embarrassment.

Why Image Sizes Matter So Much

Social media platforms aren't passive galleries—they actively reshape your images to fit their layouts. Understanding why this happens helps you work with the system instead of fighting it.

Automatic Cropping and Its Consequences

When you upload an image that doesn't match a platform's expected dimensions, the algorithm crops it automatically. This isn't optional—the platform needs consistent layouts for feeds, so it forces conformity.

Professional designers account for this by using platform-specific templates. Amateurs don't, and their content suffers. It's that simple.

Image Quality Degradation

Platforms compress uploaded images to save server storage and bandwidth. If you upload an image too small or too large, quality suffers:

• Too small: Platform upscales it, making it pixelated and blurry
• Too large: Platform downscales aggressively, introducing compression artifacts
• Just right: Minimal compression, maximum quality

The exact dimensions each platform expects result in the least quality loss. Deviate significantly, and your crisp images become muddy messes.

Mobile vs Desktop Display

Most social media consumption (60-70%) happens on mobile devices. Desktop might show your full 1920px wide image beautifully, but mobile users see a 360-414px wide screen. If critical details are too small at mobile scale, most people won't see them.

Always preview your images on actual phones before posting. What looks great on your 27-inch monitor might be invisible on an iPhone.

Instagram Image Sizes

Instagram is the most visually-focused platform, which paradoxically makes it the least forgiving about dimensions. Get sizes wrong here, and it's immediately obvious.

Instagram Feed Posts

Safe zones: Keep text and important elements at least 100px from edges. Instagram's UI overlays (likes, comments, username) can cover edge content.

Instagram Stories

Stories are vertical, full-screen experiences. The 1080×1920 canvas gives you maximum real estate, but the top 250px and bottom 250px are danger zones where Instagram's UI elements appear. Place all important text and visuals in the center 1080×1420 px area.

Instagram Reels

Reels use the same dimensions as Stories but are video-focused. Always shoot/export at 1080×1920 to maintain quality. Lower resolutions look noticeably worse, especially on newer high-resolution phones.

Instagram Profile Picture

• Display size: 110×110 px on profiles, 32×32 px in feed/comments
• Upload size: 320×320 px (minimum 110×110 px)
• Format: Displayed as circle—design with circular crop in mind

Upload at 320×320 or higher for best quality. Instagram displays profile pictures as circles, so ensure important elements (face, logo) fit within the circular frame. Corners will be cropped.

Facebook Image Sizes

Facebook has more post types than any other platform—feed posts, cover photos, events, ads. Each has different requirements.

Facebook Feed Posts

Facebook favors landscape images (1.91:1). While you can post square or portrait, landscape takes up more screen space and looks more professional in feeds.

Facebook Cover Photos

Facebook's cover photos display differently on desktop vs mobile. Desktop shows the full 820×312 area, while mobile crops to a taller viewport. Design covers with important elements centered to ensure they're visible on both.

Facebook Stories and Profile Picture

• Stories: 1080×1920 px (9:16), same as Instagram
• Profile picture: Upload 180×180 px minimum, displayed at 170×170 px on profiles, 32×32 px in comments

Twitter/X Image Sizes

Twitter (now X) has simpler image requirements than Instagram or Facebook, but precision still matters for professional appearance.

Twitter Feed Posts

Twitter's multi-image layouts are automatic based on number of images. Two images display side-by-side. Three images show one large + two small. Four images show a 2×2 grid. Design accordingly.

Twitter Header and Profile

Twitter's header photo shows behind the profile picture on the left side. Keep important elements away from the left 20% to avoid overlap.

LinkedIn Image Sizes

LinkedIn is the professional network, so image quality and proper sizing matter even more—sloppy visuals hurt your professional credibility.

LinkedIn Feed Posts

LinkedIn Profile Elements

LinkedIn's background photo is wide and short. Avoid busy designs—simple, professional images with subtle branding work best.

YouTube Image Sizes

YouTube is video-first, but thumbnails and channel art are critical for clicks and brand recognition.

YouTube Thumbnails

Thumbnails are mini-billboards for your videos. Use 1280×720 px for maximum quality. Include bold text (70-100pt font minimum), high-contrast colors, and close-up faces if possible. Thumbnails display at various sizes—300×168 px on desktop, smaller on mobile—so keep designs simple and readable.

YouTube Channel Art

YouTube channel art is tricky—different devices show different crops. Design with the 1546×423 px safe area as your main canvas, then extend the design to fill 2560×1440 px background. Keep all text and logos within the safe area.

Pinterest Image Sizes

Pinterest is uniquely vertical-focused. Tall images perform dramatically better because they take up more screen space in feeds.

Pinterest Pins

Pinterest caps pin height at 2.1:1 ratio. Anything taller gets truncated with "See more" button. The 2:3 ratio (1000×1500 px) is the sweet spot—tall enough to dominate feeds without being cropped.

TikTok Image and Video Sizes

TikTok is video-native, but understanding dimensions ensures your content fills the screen properly without black bars.

TikTok Video Specifications

TikTok's vertical format is non-negotiable. Horizontal videos display with large black bars above and below, looking unprofessional. Always shoot or export at 9:16 (1080×1920 px).

Design Best Practices Across Platforms

Beyond knowing dimensions, following design principles ensures your images look professional and perform well.

Text Readability

Mobile-first sizing:

• Minimum font size: 30-40pt for body text, 60-80pt for headlines
• Maximum text coverage: Keep text under 20% of image area (especially for Facebook ads)
• High contrast: Dark text on light backgrounds or vice versa. Avoid low-contrast combinations like yellow on white.

Safe zones for text:

• Keep text at least 5-10% from all edges
• Platform UI elements (profile pics, buttons, timestamps) often overlap edges
• Center-weighted designs are safest across all platforms

File Format and Compression

Most platforms accept JPEG and PNG. JPEG works for photos (compress to 80-85% quality). PNG works for graphics with text or transparency. Avoid uploading massive files—platforms compress them anyway, and large uploads slow down posting.

Branding Consistency

Maintain visual consistency across platforms:

• Color palette: Use brand colors consistently (2-3 primary colors)
• Typography: Stick to 1-2 fonts maximum per image
• Logo placement: Bottom corner (10% from edges), 50-150px depending on image size
• Style: Maintain consistent photo filters, graphic styles, layout patterns

Platform-Specific Optimization Tips

Instagram Optimization

• Use carousel posts: Up to 10 images in one post—great for storytelling or product showcases
• Stories highlights: Design custom cover images (1080×1920 px with centered icon/text)
• Grid planning: Preview how posts look together in your grid—use tools like Preview app or Later
• High-res uploads: Always upload at 1080px dimension minimum—Instagram's compression is aggressive

Facebook Optimization

• Video over images: Facebook's algorithm favors video—even simple slideshows outperform static images
• Link previews: Use Facebook's debugger to preview how shared links appear before posting
• Text overlay: Keep text under 20% of image for ads (use Facebook's text overlay tool to check)

LinkedIn Optimization

• Professional photography: High-quality, professional images perform better than casual snapshots
• Data visualizations: Charts, graphs, infographics get high engagement on LinkedIn
• Document posts: Upload PDFs directly (up to 100 pages, 300 MB)—they display inline in feed

Pinterest Optimization

• Text overlays essential: 70% of top pins have text overlays explaining content
• Bright colors: Vibrant, saturated colors stand out in busy Pinterest feeds
• Multiple pins per URL: Create 3-5 different designs for the same blog post/product—test which performs best
• Pin descriptions: Use keyword-rich descriptions (500 characters) with hashtags

Common Mistakes to Avoid

Mistake #1: Using One Size for All Platforms

Creating one 1920×1080 image and posting it everywhere results in poor cropping on most platforms. Invest 10 extra minutes creating platform-specific versions—the quality difference is night and day.

Mistake #2: Ignoring Mobile Preview

Designing on a desktop monitor without checking mobile preview is a recipe for disaster. Most people will see your content on phones—always preview at mobile dimensions before posting.

Mistake #3: Text Too Small or Too Close to Edges

Text that's readable on desktop becomes illegible on mobile. Use 40pt+ minimum for body text. Keep all text and important elements at least 100px from edges to avoid UI overlaps.

Mistake #4: Low-Resolution Uploads

Uploading 500×500 px images on Instagram (which expects 1080×1080 px) makes them look pixelated. Always meet or exceed platform requirements for crisp, professional appearance.

Mistake #5: Forgetting Safe Zones for Stories

Placing text at the very top or bottom of Stories means it gets covered by username, stickers, or CTA buttons. Keep all important content in the center 70% of the canvas.

Final Thoughts: Precision Equals Professionalism

Getting image sizes right isn't glamorous work, but it's the difference between content that looks professional and content that looks amateurish. When your posts consistently appear perfectly formatted—no awkward crops, no blurry photos, no cut-off text—people notice. They might not consciously think "Wow, great dimensions," but they perceive quality and professionalism.

The brands and creators who succeed on social media aren't just creating good content—they're creating content that's optimized for each platform's specific requirements. A beautiful design posted at the wrong dimensions is still a failure. A decent design posted at correct dimensions looks polished and purposeful.

Save this guide, bookmark the quick reference table, and use it every time you create social media graphics. The few extra minutes you spend ensuring proper dimensions will save you hours of frustration, embarrassment, and redos. Your audience deserves to see your content as you intended it—perfectly framed, fully visible, and professionally presented.
