Social Media Image Sizes - The Complete Guide

Profile Image

Your profile image is the face of your brand. It’s often the first thing people see, so it needs to be clear, recognizable, and consistent across platforms. Whether it’s a logo, a personal headshot, or a symbol that represents your brand, it should instantly convey who you are. Think of it as your digital handshake, it sets the tone for how people perceive your brand at a glance.

Cover Photos

Your cover photo gives you a larger visual space to make an impact. While your profile picture is fixed and minimal, cover photos give you room to showcase campaigns, promotions, events, or any brand updates you want to highlight. Since they’re the biggest visual element on your profile, they should align with your branding and be updated periodically to stay relevant.

‍

Post Images

Post images are the visuals that accompany your regular posts and updates. These can be standalone graphics or images paired with text to reinforce your message and improve engagement.

‍

Visual posts tend to be more memorable and eye-catching than plain text, making them an effective way to grab attention as people scroll through their feeds. To maximize their impact, keep your brand colors, fonts, and style consistent, but don’t be afraid to experiment with different formats and styles to see what resonates with your audience.

Shared Link Images

These are the images that preview shared links, whether it’s a product page, blog post, or external resource. A good shared link image should capture the essence of the linked content, provide context, and make people want to click. Think of it as a teaser that gives just enough information to spark curiosity. Also known as ‘link previews’. 

‍

Infographics

Infographics take complex information and break it down into a visually digestible, easy-to-remember format. Whether it’s data, step-by-step processes, industry insights, or how-to guides, infographics help turn dense information into something engaging and shareable. From product user guides to educational content, they’re a great way to communicate value quickly.

Memes

Memes are the ultimate engagement drivers. They add humor, relatability, and personality to your brand. A well-placed meme can humanize your brand, make your audience laugh, and encourage shares.

‍

That said, humor is subjective. Not every meme will land well, so make sure yours aligns with your brand voice, values, and audience interests. Also, keep them culturally relevant and steer clear of anything that could be misinterpreted.

Videos

Videos are one of the most engaging content formats across social media. Whether it’s tutorials, behind-the-scenes clips, product showcases, event coverage, or promotional content, a well-crafted video can significantly increase engagement and brand recall.

To make the most of your videos, keep them concise, dynamic, and aligned with your brand messaging. Use captions for accessibility and optimize them for each platform’s preferred format.

Thumbnails

Thumbnails are the preview images for larger content pieces like videos, e-books, or whitepapers. They might seem small, but they play a huge role in whether someone decides to click or not.

A strong thumbnail should be clear, visually striking, and relevant to the content. Use bold visuals, minimal but impactful text, and high-contrast colors to make it stand out in a crowded feed.

➡️Pro tip: TestMyThumbnails helps YouTube and video creators optimize their video thumbnails by simulating how they appear in real YouTube feeds, enabling data-driven decisions for better visibility and click-through rates.

Product Photos

If you’re selling a product, high-quality product images are non-negotiable. They should showcase your product in the best light while also telling a story about how it fits into your customers’ lives.

‍

Lifestyle images, where your product is shown in real-world use, helps potential buyers visualize themselves using it. Encourage user-generated content by featuring customer photos and testimonials, as this builds trust and credibility while keeping your content fresh and authentic.

Post Images

‍

Your post images are your daily bread on Facebook, whether you’re sharing updates, promotions, or just keeping your audience engaged. They need to be clear, high-quality, and properly scaled to avoid awkward cropping or pixelation.

• Recommended Size: 1200 x 630 pixels
• Minimum Size: 600 x 315 pixels
• Aspect Ratio: 1.91:1
• Supported Formats: JPG, PNG
• Maximum File Size: 30MB

💡 Pro Tip: Always upload images in the highest resolution possible without exceeding file size limits. A higher resolution ensures that your content remains sharp across different devices and screen sizes.

Cover Photo

‍

Your cover photo is like the welcome mat of your Facebook page, it sets the tone for visitors. It’s also one of the biggest visuals on your profile, so it needs to be strategic, high-resolution, and well-balanced.

• Desktop Dimensions: 820 x 312 pixels
• Mobile Dimensions: 640 x 360 pixels
• Safe Zone: Keep all important elements within 560 x 312 pixels to avoid them getting cut off on different screens.
• Supported Formats: JPG, PNG
• Max File Size: 100KB (smaller file sizes load faster)

💡 Profile pictures overlap cover photos slightly, especially on mobile. Avoid placing key elements like text or faces near the bottom left corner, as they may get covered.

Profile Picture

‍

This is your brand’s digital face. Whether it’s your logo or a headshot, your profile picture needs to be clear, recognizable, and consistent across platforms.

• Desktop Display: 170 x 170 pixels
• Mobile Display: 128 x 128 pixels
• Minimum Upload Size: 180 x 180 pixels
• Shape: Circular frame (even though you upload a square image, the edges will be cropped)

💡 To keep your branding intact, ensure your logo or key elements are centered, avoiding the edges where cropping occurs.

Ad Image Sizes

Facebook ads come in various formats, but thankfully, the platform has standardized most image ad dimensions.

• Single Image Ads: 1080 x 1080 pixels (1:1 aspect ratio)
• Carousel Ads: 1080 x 1080 pixels (1:1 aspect ratio, supports multiple images)
• Right Column Ads: 1200 x 1200 pixels (1:1 aspect ratio, mostly desktop view)
• Story Ads: 1080 x 1920 pixels (9:16 aspect ratio, full-screen mobile format)

Always keep 20% or less text on images to avoid reduced reach. Facebook prioritizes ads that are visually clean and engaging over text-heavy creatives.

‍

Event Cover Photo

Hosting an event? Your event cover photo should be bold, eye-catching, and informative. It’s the first thing people notice when they check out your event page.

• Ideal Size: 1200 x 628 pixels
• Aspect Ratio: 2:1

💡Since event covers display differently across devices, keep all text and important visuals centered to prevent cropping on mobile screens.

‍

Group Cover Photo

If you run a Facebook group, the group cover photo is your visual first impression. Since groups are often community-driven, this is your chance to establish a strong identity.

• Recommended Size: 1640 x 856 pixels
• Aspect Ratio: 1.91:1

💡 Facebook automatically adjusts group covers based on different screen sizes. Always preview your image on both desktop and mobile to ensure nothing important gets cut off.

‍

Video Specifications

Video content dominates Facebook. Whether you’re sharing tutorials, product launches, or behind-the-scenes clips, your video dimensions play a big role in engagement.

• Recommended Aspect Ratios: 16:9, 1:1, 4:5, 9:16 (depends on format)
• Minimum Resolution: 720p (higher is always better)
• Maximum File Size: 4GB
• Maximum Length: 240 minutes
• Supported Formats: MP4, MOV

💡 Square (1:1) and vertical (9:16) videos perform better for mobile viewers, while landscape (16:9) works best for desktop. Optimize your videos based on where your audience engages the most.

Profile Image

Your profile picture is your brand’s digital identity. It’s what appears next to your tweets, replies, and even in notifications. A poorly cropped or blurry profile image can weaken credibility, while a sharp, well-centered one makes you instantly recognizable.

• Recommended Size: 400 x 400 pixels
• Minimum Size: 200 x 200 pixels
• Aspect Ratio: 1:1 (Square, but displayed in a circular frame)
• Maximum File Size: 2MB
• Supported Formats: JPG, PNG

💡 Since Twitter crops profile pictures into a circular frame, make sure the most important elements, like your logo or face, are centered to prevent anything from getting cut off.

Header Image

Your header image is prime real estate. It’s the biggest visual on your profile and a great opportunity to reinforce your branding, highlight promotions, or showcase a mission statement.

• Recommended Size: 1500 x 500 pixels
• Aspect Ratio: 3:1
• Maximum File Size: 5MB
• Supported Formats: JPG, PNG

Here are some things to consider:

❌Your profile picture overlaps the header image slightly, so avoid placing critical design elements in that area.

✅Twitter displays headers differently across devices, sometimes cropping the edges. Keep text and key visuals toward the center to maintain readability on mobile and desktop.

Tweet Image Size

Tweets with images get 3x more engagement than plain text tweets. But, not all images are displayed the same way. You want to ensure your graphics are well-sized, properly cropped, and engaging even in preview mode.

• Recommended Size: 1200 x 675 pixels
• Minimum Size: 600 x 335 pixels
• Aspect Ratio: 16:9
• Maximum File Size: 5MB
• Supported Formats: JPG, PNG, GIF

‍
✔ Use bright, high-contrast colors to stand out in a fast-moving feed.
✔ Add minimal but impactful text. Twitter crops images in previews, so keep important words in the center.
✔ If you’re posting multiple images, Twitter lays them out in a grid, test how your images will be displayed before posting.

‍

Multi-Image Tweets

Sometimes, one image isn’t enough. If you’re posting multiple images in a single tweet, Twitter arranges them differently based on the number of images.

• 2 Images: Both displayed side by side (700 x 800 pixels recommended).
• 3 Images: One large image on the left, two smaller images stacked on the right (700 x 800 pixels for the left image, 1200 x 600 pixels for the right images).
• 4 Images: Arranged in a 2x2 grid (1200 x 600 pixels per image).

Multi-Image Posting Tips:

• Test layouts before posting, some crops can be unexpected.
• Make sure your branding or main subject isn’t cut off in the preview.
• Keep a consistent theme across all images for a cohesive look.

‍

GIFs on Twitter

GIFs are a game-changer for engagement. They’re eye-catching, loop continuously, and require zero effort from the user. Whether you’re responding with a reaction GIF or sharing branded animations, they should be optimized for quality.

• Maximum File Size: 5MB (Mobile), 15MB (Web)
• Recommended Dimensions: 1280 x 720 pixels
• Frame Rate: Up to 40fps
• Supported Formats: GIF

Why GIFs Work:
✔ They add motion to a fast-moving feed.
✔ They work well for storytelling, tutorials, and humor.
✔ They autoplay, making them instantly eye-catching.

Twitter Video 

Videos on Twitter autoplay as users scroll, making them one of the most engaging formats. But if your video isn’t sized properly, it can appear blurry, cropped, or awkwardly framed.

• Recommended Aspect Ratios: 16:9 (Landscape), 1:1 (Square), 9:16 (Vertical)
• Minimum Resolution: 720 x 720 pixels
• Maximum Resolution: 1920 x 1080 pixels
• Maximum Length: 2 minutes 20 seconds (140 seconds)
• Maximum File Size: 512MB
• Supported Formats: MP4, MOV (H.264 and AAC codecs recommended)
  ✔ Make the first 3 seconds count. Twitter videos autoplay, but users need a reason to keep watching.
  ✔ Keep it short and engaging. The sweet spot for engagement is 15–45 seconds.
  ✔ Add captions! 85% of Twitter users watch videos without sound. Captions keep them engaged.

‍

Twitter Ads

If you're running Twitter ads, image and video quality is non-negotiable. Poorly formatted visuals can lead to low engagement and wasted ad spend.

Image Ads

• Recommended Size: 1200 x 1200 pixels (1:1) or 1200 x 628 pixels (1.91:1)
• Maximum File Size: 3MB
• Formats: JPG, PNG

• Formats: MP4, MOV

✔ Use short, snappy copy, Twitter is all about quick messaging.
✔ A/B test different formats to see what resonates with your audience.
✔ Make sure your ad looks great on both desktop and mobile.

Instagram Post Sizes

You’ve got options when it comes to feed posts, but each format has its own best practices:

• Square Posts: The classic 1:1 aspect ratio. Use 1080 x 1080 pixels for high quality. These display well across devices and work great for balanced compositions.
• Portrait Posts: A vertical format with an optimal size of 1080 x 1350 pixels. This format takes up more screen space while scrolling, making it ideal for showcasing details.
• Landscape Posts: A wider format best for panoramic shots. Stick to 1080 x 608 pixels to maintain clarity. Instagram allows wider images, but they’ll get compressed on the feed.

⚡ No matter which format you choose, Instagram scales images down to 600 x 600 pixels (square), 600 x 750 pixels (portrait), and 600 x 315 pixels (landscape) for display. So, always upload at the highest recommended resolution to avoid pixelation.

‍

Instagram Carousel Sizes

Carousels allow you to post up to 10 images or videos in a swipeable format. The same dimensions apply as regular posts:

• Square: 1080 x 1080 pixels
• Portrait: 1080 x 1350 pixels
• Landscape: 1080 x 566 pixels

All carousel slides should maintain the same aspect ratio, or Instagram will crop them to match the first image.

Instagram Stories

‍

Stories demand a 9:16 aspect ratio, which means a recommended size of 1080 x 1920 pixels. This format fills the entire phone screen, making it perfect for immersive content.

• Safe zone: Keep text and essential elements within the central 1080 x 1420 pixels to prevent cropping on different devices.
• File formats: JPEG or PNG for images, MP4 or MOV for videos.
• Max video length: Each Story frame can be up to 15 seconds long. If it’s longer, Instagram automatically splits it into multiple clips.

⚡Use interactive features like polls, questions, and stickers to keep engagement high.

Instagram Reels & IGTV

Reels and IGTV are all about video content, but they have slightly different specs:

• Reels: Vertical 1080 x 1920 pixels (9:16 aspect ratio).
• IGTV Videos:
  
  • Cover photo: 420 x 654 pixels (keep text centered).
  • Video aspect ratio: 9:16 (vertical) or 16:9 (horizontal).
  • Max video length: 60 minutes for uploaded videos, but shorter videos (under 10 minutes) tend to perform better.

Instagram Profile Picture

Your profile picture might seem minor, but it’s a crucial branding element. Here’s what you need to know:

• Optimal size: 320 x 320 pixels (displays at 110 x 110 pixels).
• Format: Square images work best, but remember Instagram crops them into a circle. Keep important details in the center.

Instagram Ads Image Sizes

‍

If you’re running ads, make sure they’re formatted correctly:

• Single Image & Carousel Ads: Follow the same size guides as regular posts.
• Story Ads: 1080 x 1920 pixels with a 4:5 safe zone to prevent cropping.
• Video Ads: Should follow the recommended 9:16 (vertical) or 4:5 (portrait) aspect ratios.

Profile Images

The optimal image size for IG profile pictures is 200 x 200 pixels. And like other platforms, TikTok displays profile pictures in a circular format. Ensure the image is clear and consistent across all platforms. 

Video Dimensions and Aspect Ratios    

• TikTok’s vertical video aspect ratio of 9:16 has been magical and is one of the key reasons behind the platform’s phenomenal success. The ratio creates a more immersive viewing experience on mobile devices than almost any other ratio.
• When it comes to resolutions, TikTok isn’t picky. It supports various resolutions, but 1080 x 1920 pixels is the optimal resolution for high-quality content.

⚡️Using optimized image forms allows you to fully leverage TikTok's short-form video format for dynamic and engaging content. For more impact, utilize effects, transitions, and music to enhance viewer experience. Also, incorporate concise text overlays on videos to convey messages effectively. 

⚡️Design eye-catching thumbnails to entice viewers. Use clear visuals and consider incorporating text or captions that hint at the content. Maintain a consistent thumbnail style for brand recognition. 

⚡️Overall, stay current with TikTok trends to find out more ways to boost discoverability and engagement.

Channel Art Dimensions

The optimal dimensions for YouTube channel art are 2560 x 1440 pixels. Note that this might not display fully across all devices. But there’s a “safe area” of 1546 x 423 within this standard dimension that’s sure to display on any device, so capitalize on this and make sure it captures the most important elements. 

Video Upload

YouTube supports various resolutions, but for optimal quality, upload videos in 1080p (1920 x 1080 pixels) or higher. On the other end of the spectrum, you can’t go lower than 1280 x 720. 

Use familiar colors, fonts, and layouts across your videos. Incorporate branding elements, logos, and a tagline to create visually cohesive branding. For seamless playback, utilize file formats like MP4.

Thumbnail Size

The recommended thumbnail size is 1280 x 720 pixels, just like the videos they represent. You can vary as you need, but you must maintain a 16:9 aspect ratio. Eye-catching thumbnails evoke curiosity. But don’t get too creative, make sure you accurately represent the video content. Experiment with different thumbnail styles and monitor their impact on click-through rates.

Post Images:  

Optimal dimensions for images in LinkedIn posts are 1200 x 627 pixels. Try not to get too creative with your LinkedIn post images. Strive for clarity and professionalism for enhanced engagement.

Banner Images:

For profile banners, use images with dimensions of 1584 x 396 pixels. Don’t forget to make sure that the banner complements your professional brand.

Company Page:

Maintain a square logo with dimensions of 300 x 300 pixels for a polished company page appearance.

Video Content Dimensions:

LinkedIn supports aspect ratios from 1:1 to 2:1. Optimal dimensions are 1280 x 720 pixels for 16:9 videos.

Video Length: 

LinkedIn allows videos up to 10 minutes. But aim for concise content. Attention spans are flickery here. You must focus on delivering valuable insights within the first few minutes. 

Use your video captions to maximize the appeal and accessibility of your content. Note also that most users watch LinkedIn videos with the sound off, so you need to maximize visual cues.

‍

Pinterest

Pinterest is also visually driven, and the size of your images matters a lot. From pins that resonate with creativity to board covers and profile images that showcase your brand, mastering Pinterest's dimensions ensures your presence is a visual feast for ideas and inspiration. 

Here’s what you need to know to achieve pixel-perfect precision with your Pinterest assets:

Pin Image Dimensions:

• For standard pins, the optimal dimensions are 1000 x 1500 pixels. This vertical format maximizes visibility in the Pinterest feed.
• For square pins, 1000 x 1000 pixels work well, but you can choose others depending on the image content.
• For promotional content, use the standard pin size of 1000 x 1500 pixels. Like the vertical format above, this ensures your image stands out on your users’ feeds while also maintaining a consistent look.   

⚡️Descriptive titles are crucial for discoverability. Pinterest's search algorithm often relies on text. Craft clear and compelling titles with keywords for your pins. Utilize rich pins for automatic updates like product prices.

Board Cover

Board covers are displayed as 800 x 450 pixels. Anything bigger or smaller could impact how your image turns up across multiple seeds.

Profile Image

Maintain a square profile image with dimensions of 165 x 165 pixels. 

‍

Consistency in Branding

Branding isn’t just about logos, it’s about making your brand instantly recognizable. Keep your colors, fonts, and logos consistent across all platforms. Whether it’s your signature red or a calming shade of blue, make sure it shows up consistently in your visuals. Every post should reinforce your brand’s identity at a glance.

Optimizing for Mobile Viewing

Social media is a mobile-first world, and your content needs to match. Think about how people scroll, fast, distracted, and on small screens. Your images, videos, and text should be sharp, easy to read, and formatted for mobile. Treat your content like a pocket-sized masterpiece that grabs attention instantly.

Creating Engagement-Focused Content

Your content should spark conversations, not just sit there. Ask questions, start challenges, and create posts that encourage likes, shares, and comments. Don’t just post and hope for the best, add clear calls-to-action (CTAs) so people know what to do next. Whether it’s clicking a link, signing up, or dropping a comment, make engagement effortless.

Making Content Accessible and Inclusive

Social media should be easy for everyone to enjoy. Use alt text for images so visually impaired users can understand your content. Add subtitles to videos—not just for accessibility but because many people watch without sound. A little effort in inclusivity goes a long way in expanding your audience.

Adapting to Platform Trends

Trends shift fast, and what works on Instagram might flop on LinkedIn. Stay updated on platform-specific trends, are carousel posts dominating? Are long-form videos picking up steam? Follow platform shifts and tailor your content accordingly.
