Social media image sizes (2025 update) for every platform

When clients first started asking me to handle their social media, I figured the image part would be easy. Create one clean graphic, upload it across platforms, and the tools would adjust everything automatically.

Boy, was I wrong.

Between cropped headers, stretched thumbnails, and text that disappeared on mobile, it didn’t take long to realize that each platform plays by its own rules — and they change often. I spent way too much time backtracking, resizing, and apologizing for things that looked off once they went live.

Now, I keep a running list of up-to-date social media image sizes and build templates for the most common social media asset sizes my clients need. It helps me move faster, avoid guesswork, and keep everything looking professional from feed to ad to story.

This guide pulls all of that together—current specs, practical tips, ad dimensions, and tools I use to make the process smoother. I’ve worked with dozens of brands on organic and paid social strategy, and image sizing is one of the first things I coach teams to get right.

Why You Should Care About Social Media Image Sizes

I used to treat image sizing like an afterthought. If the content were strong, the image would carry it, right? But after managing dozens of campaigns and cleaning up more than a few formatting issues, I’ve learned it plays a much bigger role in performance than I expected.

Here’s what I pay attention to now.

Engagement depends on visual quality.

I’ve tested posts with the exact same copy and design, but different image sizes, and the difference in click-through rate was impossible to ignore. One version looked sharp and well-fitted; the other was awkwardly cropped and lost a chunk of the message.

That drop in performance was hard to ignore—and I’m not the only one who’s noticed.

According to HubSpot’s 2025 Global Social Media Trends report, Instagram, Facebook, and YouTube are the top platforms for both engagement and lead quality, and every one of them is powered by visuals. If your images are misaligned, off-brand, or low-res, you’re missing opportunities before your audience even reads the caption.

Ads get rejected or underperform.

One of the first paid campaigns I ran through Meta was rejected for something I didn’t catch: an image that didn’t meet their minimum width requirement. No warning, no adjustment — just silence. I didn’t even realize it hadn’t run until I checked the analytics a few days later.

LinkedIn can be just as strict. I’ve seen image ads quietly throttle their reach because the size wasn’t quite right, or the aspect ratio threw off the preview. If you’ve ever watched a high-performing campaign stall for no apparent reason, image formatting is one of the first things to check.

Your brand looks inconsistent.

Cropped-off logos. Misaligned visuals. Graphics that look perfectly fine on desktop but fall apart on mobile. I’ve been there and so have your customers.

Those inconsistencies add up. They make your brand feel disjointed, even if the message is right. After I started using platform-specific dimensions, our visuals finally felt consistent on every screen. No missing margins. No off-brand templates. Just clean, reliable content that felt intentional across every channel.

And that matters, because visuals are often the first impression your audience gets.

Social Media Image Sizes At-a-Glance

Social Media Image Sizes by Platform

I used to try to get away with a one-size-fits-all approach. I’d design once, resize for two or three channels, and call it a day. That never worked out the way I hoped.

Every platform handles visuals differently — some crop aggressively, some downscale uploads, and others prioritize entirely different aspect ratios. Now I work from a detailed spec sheet and build everything with those dimensions in mind.

Here’s the breakdown I keep bookmarked.

Facebook Image Sizes

Profile: 320 x 320 px
Cover: 851 x 315 px
Feed post: 1080 x 1350 px
Stories: 1080 x 1920 px
Ad formats:

Feed: 1080 x 1080 px
Link ad: 1200 x 628 px
Story ad: 1440 x 2560 px

Link preview: 1200 x 630 px

I’ve seen the most issues here with cover photos — what looks good on desktop can get oddly cropped on mobile. When in doubt, center your focal point and keep important details away from the edges.

Instagram Image Sizes

Profile: 320 x 320 px
Square post: 1080 x 1080 px
Portrait: 1080 x 1350 px
Landscape: 1080 x 566 px
Stories and Reels: 1080 x 1920 px
Grid thumbnail: 161 x 161 px
Reels cover: 420 x 654 px
Ad formats: same dimensions as organic posts

For Instagram, I focus on the vertical format since most of the feed is optimized for visuals that are 4:5 or taller. Square still works, but portrait images tend to perform better in terms of reach and engagement.

If Instagram is a major channel for your team, HubSpot’s free Instagram template can help you build a cohesive grid and maintain consistent brand visuals.

Twitter (X) Image Sizes

Profile: 400 x 400 px
Header: 1500 x 500 px
Feed post:

Landscape: 1600 x 900 px
Portrait: 1080 x 1350 px

Link preview: 1200 x 630 px
Ad formats:

Single image: 1200 x 628 px
Square: 800 x 800 px
Carousel: 800 x 418 px

I’ve had good luck with landscapes on X, but I’ve recently started testing more portrait crops. The mobile preview space has shifted, and portrait images get more screen real estate when done correctly.

TikTok Image Sizes

Profile: 200 x 200 px
Feed, Stories, Carousel: 1080 x 1920 px
Ad options:

Vertical (min): 540 x 960 px
Carousel: 1200 x 628 px (landscape)

Most visuals here are full screen, so I treat TikTok like a vertical-first platform. Even the ads need to match that format to avoid awkward black bars.

LinkedIn Image Sizes

Profile: 400 x 400 px
Cover images:

Personal: 1584 x 396 px
Company: 1128 x 191 px

Feed post: 1200 x 627 px
Life tab:

Hero: 1128 x 376 px
Gallery: 900 x 600 px

Ad specs:

Carousel: 1080 x 1080 px
Sponsored content: 1200 x 627 px

For LinkedIn, brand polish matters. I double-check everything — especially on company pages — because even slight misalignment stands out in a professional feed.

To go deeper on optimizing LinkedIn for lead gen or brand building, I recommend HubSpot’s LinkedIn publishing tips and post creation workflows.

Pinterest Image Sizes

Profile: 165 x 165 px
Cover: 800 x 450 px
Standard pin: 1000 x 1500 px (2:3 aspect ratio)
Carousel or ad: 1000 x 1000 or 1000 x 1500 px
Story pins: 1080 x 1920 px

Pinterest leans heavily into vertical. If I stick to 2:3 for pins, I avoid any awkward auto-cropping, especially in the mobile feed.

Pinterest can drive a surprising amount of referral traffic if images are done right. This HubSpot overview on image best practices helped shape how I think about vertical visuals across platforms, not just on Pinterest.

YouTube Image Sizes

Profile: 800 x 800 px
Banner: 2560 x 1440 px

Safe zone: center content within 1546 x 423 px

Thumbnail: 1280 x 720 px
Podcast thumbnail: 1280 x 1280 px

YouTube’s banner size can be tricky. What looks good on a desktop might get cropped on a TV or mobile device. I test previews on all devices before finalizing.

Threads Image Sizes

Profile: 320 x 320 px
Feed post: 1440 x 1920 px
Link preview: 1200 x 600 px
Carousel: up to 20 images

Threads content is often cross-posted from Instagram, so I use the same image dimensions and safe zone rules. Portrait orientation tends to display best.

Snapchat Image Sizes

Profile: 320 x 320 px
Geofilter: 1080 x 1920 px
Ads: 1080 x 1920 px
Banner: 375 x 278 px

With Snapchat, everything is built for the phone screen. I keep designs simple, vertical, and clutter-free near the top and bottom edges.

Google Business Profile Image Sizes

Logo: 720 x 720 px
Profile: between 250 and 750 x 750 px
Cover: 1024 x 576 px
Video: 1280 x 720 px (max 30 seconds, 75 MB file size)

These visuals appear across Maps, Search, and business listings, so I treat them like front-door signage — clean, high-resolution, and brand-aligned.

Bluesky Image Sizes

Profile: 400 x 400 px
Banner: 1500 x 500 px
Feed image: 1200 x 627 px
Post image: 1080 x 1080 or 627 x 1200 px

The platform allows some flexibility, but sticking with standard aspect ratios (1:1 or 4:5) keeps things crisp across different screens.

Tumblr Image Sizes

Profile: 128 x 128 px
Banner: 3000 x 1055 px
Post image: 500 x 750 px
Ads: 1280 x 1920 px

Tumblr still favors vertical imagery and posts that are graphic-forward. I’ve seen stronger results when visuals are kept light on text and optimized for mobile scrolling. It’s worth testing vertical formats here—even legacy platforms have loyal communities.

Image Sizes for Paid Social Ads

Ad specs can be slightly different from organic posts, even when they appear similar in the feed. I’ve learned to double-check image dimensions before launching any campaign. It helps avoid rejections, scaling issues, and blurry visuals that eat into performance.

Here’s what I keep on hand when building creative for paid social.

Here’s a quick guide from HubSpot on image requirements for social posts.

Tools and Templates for Social Media Assets

I’ve used everything from Photoshop to Paint in a pinch, but over time, I’ve built a go-to stack of tools that simplify sizing, designing, and reformatting social media graphics. These are the tools I return to again and again, especially when I need to resize or reformat social media asset sizes quickly and consistently.

Canva

If I’m building something from scratch or need a quick resize, Canva is the first place I go. Their templates are already optimized by platform, and the drag-and-drop editor makes it easy to maintain brand consistency. I especially like the ability to create custom folders for each client or campaign.

Built-in templates for feed posts, stories, ads, banners, and more
Resize tool for reformatting one design across platforms
Free and Pro versions available

Pixlr

When I need to clean up an image or crop something quickly, I use Pixlr. It’s a lightweight browser-based tool with just enough photo editing features to get the job done, without feeling overwhelming.

Good for fast edits, crops, or overlays
Supports layering, transparency, and filters
Free to use, with advanced features behind a paywall

Adobe Express

Adobe Express is great when I need more design flexibility without jumping into Photoshop. It’s fast, web-based, and comes with a growing collection of pre-sized templates for all major platforms.

Ideal for branded campaigns or content that needs polish
Easy-to-use animation and video features
Supports JPG, PNG, and transparent backgrounds

Adobe Express also makes it easy to format videos for different platforms, which is becoming more important as social feeds lean more heavily into short-form video. If you're keeping an eye on where video is headed this year, HubSpot’s Social Media Video Trends report offers a helpful look at what’s performing and why.

Hubspot Social Media Templates

For consistent branding across platforms, I rely on HubSpot’s free social media image templates. These are especially useful when I’m onboarding a new brand or reworking a content calendar, and they’ve saved me hours when resizing social media assets across channels.

Includes editable templates for Facebook, Instagram, LinkedIn, Twitter, and Pinterest
Sized to match current platform requirements
Compatible with Canva and other design tools

If you‘re using HubSpot’s Marketing Hub, you can also manage and publish directly through the Social Inbox tool, which helps keep content and image assets organized in one place.

Tips for Better Image Optimization

Sizing your images correctly is a great start, but fully optimizing them requires a few extra steps. These are the tactics I now use as a default when prepping social media visuals.

Mobile-first design: Most engagement happens on phones. I always test how visuals look in mobile previews and adjust spacing, font sizes, and placement accordingly.

Pro tip: I test every image in preview mode across desktop and mobile before publishing. It takes 30 seconds, and it’s caught more issues than I can count.

Safe zones matter: For stories, reels, and ads, I leave room at the top and bottom — usually around 250 to 340 pixels — to ensure that buttons, logos, or UI overlays don’t cover up anything important.
Use JPG for photos, PNG for logos: I stick to JPGs for photos because they are lighter and load faster. For logos, icons, or any design element with transparency, PNGs keep things sharp and clean.
Stay consistent across platforms: Even when the specs change, the brand elements don’t. I use the same color palette, typography, and layout structure to build recognition, regardless of where the image appears. I follow the same approach for website visuals, too, keeping image sizes consistent so everything loads cleanly and looks sharp across touchpoints. This article on website image sizes is one I come back to often.
Review AI-generated images manually: Tools like Adobe Firefly or Canva’s AI helpers can speed up production, but I always review outputs carefully. They occasionally miss brand guidelines or crop things in weird ways. AI is great for drafts, but polish still matters.

And authenticity is what wins. In fact, 76% of marketers say their most relatable, lightly produced content performs better than polished campaigns, which means your visuals don’t have to be fancy, just correctly sized and true to your brand.

Why Image Sizing Is Worth the Effort

It took a few campaigns — and more than a few resizing regrets — before I understood just how much image sizing impacts performance. Once I started tailoring visuals to each platform’s specs and aligning them with correct social media asset sizes, I noticed sharper images, stronger engagement, and far fewer issues with paid ads.

One campaign still comes to mind. We were promoting a product launch and created a single image to use across every channel. On the desktop, it looked great. But on mobile, our CTA was cropped. After swapping in a properly sized portrait version, click-throughs jumped 27% overnight.

The fix was easy. The results weren’t something we could have achieved with guesswork.

And we’re not the only ones shifting focus. Nearly two-thirds of marketers now prioritize quality over quantity, which means that every image needs to do its job. Getting the size right is one of the easiest ways to ensure it does.

It’s a small step that makes a big difference. And once you work it into your process, it’s hard to imagine going back.

FAQs

Have questions? Here are a few of the most common ones I hear from teams trying to get their images right the first time.

What size should social media images be?

Social media image sizes vary by platform, but the most commonly used dimensions are 1080 x 1080 pixels for square posts, 1080 x 1350 for portrait posts, and 1080 x 1920 for stories or full-screen vertical content.

What’s the best aspect ratio for social media?

The best aspect ratios are 1:1 for square feed posts, 4:5 for portrait images, and 9:16 for stories, reels, and other vertical formats.

Should I use JPG or PNG for social posts?

Use JPG for photos and full-image backgrounds because they load faster. Use PNG for graphics, logos, or images that need transparency or sharper lines.

What happens if I upload the wrong size?

If your image is the wrong size, it may be cropped, compressed, or rejected by the platform. This can make your post look unprofessional and negatively impact performance. That’s why I always test image previews before publishing.
