Social Media Image Sizes: The Complete Guide for Every Platform

Getting your social media image sizes wrong doesn’t just cost you a few awkward crops. A stretched Facebook cover photo, a cropped LinkedIn banner, or a TikTok clip with text buried under the like button are the kind of avoidable mistakes that make an otherwise well-run business look unprofessional online. Platforms update their specifications often enough that a chart saved a couple of years ago can quietly mislead you today.

This guide sets out the current social media image sizes for every major platform, the safe zones that most size charts skip entirely, a short note on alt text, and a practical workflow for resizing assets without redesigning them six times over. Whether you manage your own channels or brief an in-house designer, it’s worth bookmarking.

Social Media Image Sizes at a Glance

Here are the social media image sizes we reference most often when briefing design work for clients across Northern Ireland, Ireland and the UK. These image dimensions and social media dimensions cover the placements that come up most in day-to-day briefs. Full details on each platform, including safe zones and file format guidance, follow below the table.

One quick note before the platform detail: use JPG for photographs and PNG for graphics, logos or anything with text, and keep most files under 8 MB unless a platform specifically asks for larger.

Why Social Media Image Sizes Matter

Uploading the wrong social media image sizes isn’t just untidy, it actively works against the credibility a business is trying to build. A pixelated profile photo suggests a brand that doesn’t pay attention to detail. A Facebook cover image with a phone number cropped out means customers can’t reach you from the one place they looked. A LinkedIn banner that looks fine on desktop can display completely differently on mobile, where most LinkedIn members now browse.

There is a reach dimension too. Instagram and TikTok both favour content in their native aspect ratio because the platform doesn’t need to reprocess or crop it before display, and non-native formats can quietly reduce organic reach without any notification ever appearing in your analytics. Getting your social media dimensions right the first time is basic housekeeping that pays off every time you post, and it’s far cheaper than redesigning a campaign after launch because half the text disappeared behind a caption box.

Think of a social profile as a shop front. It’s a small detail, but the care taken over image dimensions and aspect ratio says something about the care behind the product or service on offer. If keeping every platform’s sizes straight feels like a moving target, our social media marketing team handles this as part of ongoing content management for several clients.

Instagram Image Sizes

Instagram is the most visually demanding platform to get right, and its social media image sizes come in more variations than most. It uses three feed orientations, a full-screen vertical format, and a grid view that crops everything to a square, so a design decision made for one orientation affects how the same image looks in a completely different context elsewhere on the profile.

Profile photo: 320 x 320 pixels, displayed as a circle. Keep a logo or headshot centred with clear space around the edges; text near the corners of a square image gets cut off entirely.

There’s no single Instagram size that covers every placement. Feed posts come in three aspect ratios. Square (1080 x 1080, 1:1) is the safest option for repurposing content across platforms. Portrait (1080 x 1350, 4:5) is the recommended format for feed posts specifically, since it takes up more screen space in the feed and tends to improve visibility. Horizontal (1080 x 566, 1.91:1) performs worst for organic reach and suits panoramic shots or widescreen video stills rather than everyday posting.

On the profile grid, every image displays as a square regardless of its original aspect ratio, so keep the most important visual information within the central square of any portrait or horizontal upload, particularly faces, logos and any text that needs to remain legible.

Safe Zones for Instagram Reels and Stories

Reels and Stories run at 1080 x 1920 pixels (9:16), full-screen vertical, and this is where most social media image sizes guides stop short. Knowing the dimensions is close to useless if a design sits behind Instagram’s own interface. The username, audio name and caption occupy the bottom 25 to 35% of the screen. Engagement buttons take up roughly 15% of the screen width down the right-hand side of the lower half, and a progress bar runs across the very bottom edge.

The practical rule: keep text, logos and any call to action within the upper 50% of the frame, centred horizontally with margin on both sides. Canva’s safe zone overlay is worth switching on before placing a single text element, and it takes seconds to check once the habit sticks.

Facebook Image Sizes

Facebook remains one of the most widely used platforms for SMEs running local advertising across Northern Ireland, Ireland and the UK, and getting the social media image sizes right here is basic housekeeping that’s often done poorly, particularly on mobile, where the cover photo displays in a narrower crop than on desktop. Facebook’s social media dimensions catch out even experienced marketers because desktop and mobile crop the same upload differently.

Profile photo: 170 x 170 pixels on desktop, shown as a circle. Upload at a higher resolution (400 x 400 minimum) and let Facebook compress it; the result is noticeably sharper than uploading at the minimum size and takes no extra effort.

Cover photo: 1200 x 628 pixels, though Facebook displays it at 820 x 312 on desktop and 640 x 360 on mobile. Design with the mobile crop in mind and keep contact details or key branding away from the top and bottom edges, since that’s exactly where the crop trims first.

Feed post photos: 1200 x 630 pixels, or 1080 x 1080 for square, which displays more consistently across devices and suits carousel posts. Stories follow the same 1080 x 1920 dimensions and safe zone rules as Instagram, so one Story design can often serve both platforms.

For paid campaigns, the standard Facebook ad image size is 1200 x 628 (1.91:1). These image dimensions and this aspect ratio also work well for boosted posts. Keep text coverage light within the image itself; heavy text reduces reach regardless of how well the campaign is targeted or how strong the offer behind it is.

LinkedIn Image Sizes

LinkedIn is where B2B credibility gets built, and the visual bar here sits higher than on more casual platforms. Getting LinkedIn’s social media image sizes right takes minutes and pays off in credibility every time someone views the page. A blank company banner, or one clearly designed for a different ratio and stretched to fit, undermines the professional impression a business has spent time building through its posts and comments.

Personal profile photo: 400 x 400 pixels, circular crop, using a clear professional headshot rather than a cropped group photo.

Personal banner: 1584 x 396 pixels, a wide, shallow format that many people leave blank. That’s a missed opportunity, particularly for business owners and senior staff who use LinkedIn for client-facing activity and thought leadership.

Company page logo: 300 x 300 pixels, appearing beside every post the page publishes, so it needs to read clearly at a small size.

Company page banner: 1128 x 191 pixels, narrower than the personal banner and needing a design built for that aspect ratio rather than a scaled-down horizontal image, which rarely looks intentional. These image dimensions are easy to get wrong if a designer starts from the personal banner template instead.

Feed post image: 1200 x 628 for horizontal orientation, 1080 x 1080 for square. Square tends to display most consistently across devices. Businesses juggling LinkedIn’s social media dimensions alongside a wider content calendar often find it easier with a proper publishing structure behind it; our content marketing team builds that structure for clients whose channels need to stay consistent without a full-time hire.

TikTok, X and YouTube Image Sizes

Three more platforms round out the core set of social media dimensions most SMEs need on file: TikTok for short-form video, X for real-time updates, and YouTube for long-form content and search visibility. These social media image sizes matter less on a daily posting basis but still shape first impressions, and each platform favours its own aspect ratio for the header or profile placement.

TikTok

TikTok’s format is almost entirely video, but profile image quality still matters as more UK businesses use the platform for discovery rather than just entertainment. Profile photo: 200 x 200 pixels, shown at a small display size, so keep it bold and identifiable at a glance. Video: 1080 x 1920 pixels (9:16).

TikTok’s interface covers more of the screen than any other platform: username, caption and audio label sit across the bottom 35%, engagement buttons run down the right-hand side from roughly the 40% mark to the bottom, and the TikTok logo sits fixed in the lower-right corner. The same upper-50%-safe-zone rule from Instagram Reels applies here, only with slightly more margin needed at the bottom edge.

X (Twitter)

X isn’t primarily a visual platform, but the header image is often neglected. Profile photo: 400 x 400 pixels, circular. Header photo: 1500 x 500 pixels; the profile photo overlaps the lower-left corner on desktop, so keep key design elements clear of that area. In-stream images: 1600 x 900 pixels (16:9). X no longer forces timeline images the way it once did, but keeping the subject centred still matters for the preview crop shown before a user clicks through to the full post.

YouTube

YouTube is the second-largest search engine in the world, and channel presentation matters beyond individual video quality. Channel art: 2560 x 1440 pixels, though YouTube displays it differently by device, from 2560 x 423 on a television down to 1280 x 350 on a tablet. Design the core message to sit within the central 1546 x 423 area so nothing important gets cropped on smaller screens. Profile photo: 800 x 800 pixels, circular.

Video thumbnail: 1280 x 720 pixels (16:9), under 2 MB, saved as JPG or PNG; thumbnails are one of the highest-impact design decisions on the platform because they drive click-through rate directly, often more than the title itself. Businesses building a proper video library rather than posting the occasional clip may want thumbnail design handled alongside production; that’s part of what our video production service covers from scripting through to the final export.

Pinterest and Google Business Profile Image Sizes

Two more social media image sizes are worth getting right, even though these placements see less daily attention than the platforms above. The image dimensions and social media dimensions here differ sharply from the mostly square formats covered so far.

Pinterest

Pinterest is an underused traffic source for UK SMEs in interiors, food, fashion and craft. Profile photo: 165 x 165 pixels, circular. Standard Pin: 1000 x 1500 pixels (2:3); Pinterest is vertical-first, and this aspect ratio is the one to design around from the start rather than adapt afterwards, since horizontal images perform poorly there.

Google Business Profile

Google Business Profile images are among the most commercially important images a business publishes, appearing directly in Google Search and Maps results, yet they’re frequently overlooked by SMEs who focus their visual effort on Facebook and Instagram instead. Logo: 720 x 720 pixels. Cover photo: 1080 x 608 pixels (roughly 16:9). Business photos: minimum 720 x 720 pixels, between 10 KB and 5 MB. Complete, high-quality photo sets consistently correlate with more direction requests and website clicks than incomplete or low-quality ones, and checking this is one of the first things our SEO team reviews when auditing a local business’s presence.

Why Your Images Look Blurry: File Formats and Compression

Getting the social media image sizes and aspect ratio right on paper doesn’t guarantee a sharp result once a platform’s compression algorithm has finished with the file. Even correct social media dimensions can look soft once a platform compresses the file down for its own servers. Use JPG for photographs and PNG for graphics, logos or anything containing text; PNG preserves sharp edges without the compression artefacts that ruin fine detail. WebP is worth using where a platform supports it, since it tends to hold quality at a smaller file size than either of the older formats.

The most reliable fix for blurry uploads is over-exporting: saving a design at roughly twice the pixel dimensions the platform asks for, so the platform’s own compression algorithm has more information to work with rather than stretching a file that was already at the minimum size. As Ciaran Connolly, founder of ProfileTree, puts it: “Every platform compresses on upload, so we always export client assets larger than the spec and let the platform do the shrinking, not the other way round.”

Keep most files under 8 MB, check the exported version at its actual display size before publishing, and avoid trusting a design tool’s preview, which rarely reflects the compression a platform applies afterwards.

Accessibility: Alt Text and Image Dimensions

Correct social media image sizes support accessibility as well as appearance. Getting the image dimensions right also helps here: a design that’s legible at its intended dimensions is more likely to be legible to someone using a screen magnifier or viewing on a low-end device with a small screen.

Alt text matters just as much as the dimensions themselves. Write a plain, factual description of what the image shows rather than stuffing it with keywords; most platforms display alt text to screen reader users, and some also use it to inform how content gets recommended. Avoid relying on text baked into an image to convey information a customer needs, such as an offer, a date or a phone number, since screen readers can’t read pixels. Where text in an image is unavoidable, repeat the same information in the caption.

A Quick Batch-Resizing Workflow

A consistent process for producing social media image sizes across platforms saves far more time than it costs to set up, and keeping a master reference of your social media dimensions means you’re not rebuilding the same chart every quarter. Managing image dimensions across six or more platforms becomes unsustainable once every placement gets exported by hand. Start by designing at the largest size needed, typically 1080 x 1920 for Stories, Reels and TikTok, keeping the key message within the upper half of the canvas from the outset.

From that master file, export scaled versions. Canva’s paid Resize function generates several dimensions from one canvas in a single step; Photoshop can export multiple artboards together; Lightroom lets you save custom export presets per platform and reuse them on every project afterwards.

Before scheduling anything, check each exported version visually rather than assuming the export tool got it right. The move from a 9:16 canvas to a 1:1 crop is where content most often breaks, since elements placed in the lower third of the vertical version can disappear entirely once squared off. A thirty-second check on each export catches the more embarrassing errors before they go live.
