Social Media Image Sizes: The Complete 2026 Guide for Every Platform

Getting your social media image sizes wrong costs you more than you might think. A stretched Facebook cover photo, a cropped LinkedIn banner, or a TikTok Reel with text buried under the like button — these are the kinds of avoidable mistakes that make an otherwise well-run business look unprofessional online.

This guide covers the current image dimensions for every major platform, updated for 2026. Beyond a list of numbers, you will find guidance on safe zones for vertical video, a practical batch-resizing workflow, and notes on designing social ads that meet UK Advertising Standards Authority requirements for legibility. Whether you handle your own social media or brief an in-house team, keep this page bookmarked.

2026 Social Media Image Size Cheat Sheet

If you need the numbers quickly, start here. The table below covers the most commonly used image placements across the major platforms. Detailed breakdowns for each platform follow below.

One quick note on file format before the platform detail: use JPG for photographs and PNG for graphics, logos, or any image containing text. PNG preserves sharp edges without compression artefacts. For most platforms, keep file sizes under 8 MB.

Why Social Media Image Sizes Matter for Your Brand

Uploading the wrong dimensions is not just untidy; it’s wrong. It actively works against the credibility you are trying to build.

A pixelated profile photo suggests your brand does not pay attention to detail. A Facebook cover image with your phone number cropped out means customers cannot reach you from the one place they looked. A LinkedIn banner that looks fine on desktop may display completely differently on mobile — and the majority of LinkedIn users now access the platform on their phones.

There is also a reach dimension to this. Instagram and TikTok both favour content that uses their native aspect ratios because the platforms do not need to reprocess or crop it before displaying it. Non-native formats can quietly reduce your organic reach without any notification.

Think of your social profiles as your visual shop front. The care you take with images signals something about the care you bring to your work.

Platform-by-Platform Image Dimensions

The specifications below cover the major platforms that SMEs in Northern Ireland, Ireland, and the UK are actively using. Each section includes the key placements — profile photo, cover or banner, feed posts, and any video or stories format where relevant. Check the safe zones section after this if you are designing for vertical video formats; dimensions alone will not tell you where it is safe to place text.

Instagram Image Sizes

Instagram is the most visually demanding platform to get right. It uses three feed orientations, full-screen vertical formats, and a grid view that crops everything to a square — meaning your design decisions for a portrait post affect how it looks in two completely different contexts.

Profile photo: 320 x 320 pixels. Instagram displays this as a circle, so keep your logo or headshot centred with clear space around the edges. Text near the corners of your square image will be cut off.

Feed posts come in three orientations. Square (1080 x 1080 pixels, 1:1) is the safest cross-platform option for repurposing content. Portrait (1080 x 1350 pixels, 4:5) is the recommended format for feed posts specifically—it takes up more screen real estate, improving visibility in the feed. Landscape (1080 x 566 pixels, 1.91:1) is the least effective for organic reach and is better suited to specific use cases, such as panoramic photography or widescreen video stills.

On your profile grid, all images display as squares regardless of their original orientation. Keep the most important visual information within the central square area of any portrait or landscape image you upload.

Stories and Reels: 1080 x 1920 pixels (9:16). Full-screen vertical. Read the safe zones section below before you design anything for these formats — significant portions of the screen are covered by Instagram’s own interface elements.

Facebook Image Sizes

Facebook remains the most widely used social platform for SMEs running local advertising across Northern Ireland, Ireland, and the UK. Getting your profile and cover images right is basic housekeeping, but it is often done poorly — particularly on mobile, where the cover photo is displayed in a narrower crop than on desktop.

Profile photo: 170 x 170 pixels on desktop, displayed as a circle. Upload at a higher resolution (at least 400 x 400) and let Facebook compress it; this produces a noticeably sharper result than uploading at the minimum resolution.

Cover photo: 1200 x 628 pixels. Facebook displays this at 820 x 312 pixels on desktop and 640 x 360 on mobile. Design with the mobile crop in mind and avoid placing contact details or critical branding near the top or bottom edges.

Feed post photos: 1200 x 630 pixels, or 1080 x 1080 for square format. Square displays more consistently across devices and is the recommended size for carousel posts.

Facebook Stories: 1080 x 1920 pixels (9:16). The same safe zone considerations as Instagram apply.

For businesses running paid social campaigns on Facebook, the standard ad image size is 1200 x 628 pixels (1.91:1). Keep text minimal within the image itself — heavy text coverage reduces reach on Facebook ads regardless of how well targeted the campaign is.

LinkedIn Image Sizes

LinkedIn is where B2B credibility is built, and the visual standards expected here are higher than on more casual platforms. A blank company page banner, or one clearly designed for a different dimension and then stretched to fit, undermines the professional impression you have spent time establishing.

Personal profile photo: 400 x 400 pixels, displayed as a circle. Use a clear, professional headshot.

Personal banner: 1584 x 396 pixels. This is a wide, shallow format that many users either leave blank or fill with a generic image. It is a missed opportunity — particularly for business owners and senior team members who use LinkedIn for client-facing activity.

Company page logo: 300 x 300 pixels. This appears next to every post your company page publishes, so quality matters.

Company page banner: 1128 x 191 pixels. This is narrower than the personal banner and requires a design tailored to the format. Scaling down a landscape image rarely produces a professional result.

Feed post image: 1200 x 628 pixels for landscape, 1080 x 1080 for square. Square tends to display most consistently across devices on LinkedIn.

If your team manages a LinkedIn company page alongside your website and is finding it difficult to keep both consistent, ProfileTree’s content marketing service can help build a publishing structure that keeps your channels aligned.

X (Twitter) Image Sizes

X, formerly Twitter, is not primarily a visual platform, but that does not mean your images should be an afterthought. The header photo in particular is often neglected — leaving the default background or uploading a blurred landscape image on an otherwise active account undercuts the impression you are making.

Profile photo: 400 x 400 pixels, displayed as a circle.

Header photo: 1500 x 500 pixels. On desktop, the profile photo overlaps the lower-left corner of the header image. Keep important design elements clear of that area.

In-stream images: 1600 x 900 pixels (16:9). X no longer forces-crops images in the timeline the way it once did — clicking through shows the full image at its original dimensions. Keep the subject matter centred for the preview crop that appears before a user clicks.

TikTok Image Sizes

TikTok’s format is almost entirely video-based, but profile image quality still matters — particularly as more UK businesses use TikTok as a discovery channel.

Profile photo: 200 x 200 pixels. It appears next to every piece of content you post and at a very small display size. Keep it simple, bold, and identifiable at a glance.

Video: 1080 x 1920 pixels (9:16). The safe zone section below is essential reading before you design TikTok video content. The interface elements on TikTok — username, caption, and the engagement button column on the right-hand side — cover more of the screen than on any other platform, and the placement is not immediately obvious until you have published content that disappears behind them.

For SMEs exploring short-form video, ProfileTree’s video production service covers scripting, filming, and editing specifically for social formats, including TikTok and Instagram Reels.

YouTube Image Sizes

YouTube is the second-largest search engine in the world. For businesses investing in video content, how your channel looks matters beyond the quality of individual videos.

Channel art (banner): 2560 x 1440 pixels. YouTube displays this at different dimensions depending on the device — from 2560 x 423 on a television to 1546 x 423 on a desktop to 1280 x 350 on a tablet. Design your banner so that the core information sits within the central 1546 x 423 area; anything outside that zone will be cropped on smaller screens.

Profile photo: 800 x 800 pixels, displayed as a circle.

Video thumbnail: 1280 x 720 pixels (16:9), under 2 MB, saved as JPG, GIF, BMP, or PNG. The thumbnail is one of the highest-leverage design decisions for any YouTube channel. It directly affects click-through rate — use high contrast, readable text at small sizes, and a consistent visual style across your uploads.

Standard video resolution: 1920 x 1080 pixels for HD. 1280 x 720 is the minimum to meet HD requirements.

ProfileTree’s YouTube marketing service includes channel optimisation and thumbnail design alongside video production — relevant for businesses building a content library rather than publishing occasional one-off videos.

Pinterest Image Sizes

Pinterest is an underused traffic source for UK SMEs, particularly in sectors such as interiors, food, fashion, and craft. For businesses in those industries, the platform can drive sustained referral traffic if content is formatted correctly.

Profile photo: 165 x 165 pixels, displayed as a circle.

Standard Pin: 1000 x 1500 pixels (2:3). Pinterest is a vertical-first platform. Landscape images perform poorly. The 2:3 ratio is the standard — anything significantly taller than this risks being collapsed by the feed algorithm.

Google Business Profile Image Sizes

Google Business Profile images are among the most commercially significant images your business publishes online, and they are frequently overlooked by SMEs who focus their visual effort on Facebook and Instagram. These images appear directly in Google Search and Google Maps results — often the first impression a local customer gets of your business.

Logo: 720 x 720 pixels. Cover photo: 1080 x 608 pixels (approximately 16:9). Business photos: Minimum 720 x 720 pixels, between 10 KB and 5 MB.

Businesses with complete, high-quality photo sets on their Google Business Profile consistently receive more direction requests and website clicks than those with incomplete or low-quality images. It is one of the first things ProfileTree’s SEO team checks when auditing a local business’s digital presence in Northern Ireland or across the UK.

Safe Zones for Vertical Video

Knowing that TikTok and Instagram Reels use 1080 x 1920 pixels is essentially useless if you place your key content in an area covered by the platform’s own interface. This is the detail most image size guides skip, and it is where most Reels and TikTok content goes wrong.

On TikTok, the following UI elements are fixed on the screen. The username, caption, and audio track label sit across the bottom 35% of the screen. The like, comment, share, and follow buttons occupy the right-hand side, roughly from the 40% mark down to the bottom. The TikTok logo sits in the lower-right corner.

On Instagram Reels, the layout is similar. The username, audio name, and caption sit across the bottom, 25-35% of the screen. Engagement buttons occupy the right-hand side, taking up approximately 15% of the screen width in the lower half. A progress bar runs across the very bottom.

The practical rule is straightforward: keep your text, logo, and any call to action within the upper 50% of the 9:16 frame, centred horizontally with margin on both sides. If you are designing in Canva, look for the safe zone overlay before placing any text elements.

For businesses running paid social ads on these platforms, this matters beyond aesthetics. Any disclaimer text — terms and conditions, pricing qualifications, or regulatory notices required under UK Advertising Standards Authority guidelines — must clear these zones and remain legible on a mobile screen. For financial services, property, and healthcare advertisers in the UK, illegible or cropped disclaimer text is not just a design problem; it is a compliance risk.

How to Batch-Resize Images Quickly

Managing image dimensions across six or more platforms becomes unsustainable when you manually export a separate file for each placement. The following workflow is how social media managers handling multiple client accounts typically approach it.

Start by designing at the largest required size. For most workflows, this is 1080 x 1920 pixels (9:16), which covers Stories, Reels, and TikTok. Keep your key message and any text within the upper 50% of the canvas, centred horizontally.

From that master file, export scaled versions. In Canva, the Resize function on the paid plan generates the same design at multiple dimensions in a single step: 1080 x 1080, 1080 x 1350, and 1200 x 628 from one canvas. In Adobe Photoshop, set up multiple artboards and export them together. In Lightroom, save custom pixel-dimension presets for each platform in the Export dialogue and apply them in a single export run.

Before scheduling anything, visually check each version. The 9:16 to 1:1 crop is where content most commonly breaks — elements placed in the lower third of the vertical version disappear entirely when the image is cropped to square. A thirty-second visual check on each export prevents the more embarrassing errors from going live.

For SMEs without a dedicated design resource, Canva’s free tier covers most standard social image creation needs. The paid plan becomes worthwhile once you regularly manage content across three or more platforms — the resize function alone is worth the subscription cost in time saved.

Conclusion

Social media image sizing is the kind of foundational task businesses get wrong once, rarely revisit, and then wonder why their content looks inconsistent. The platforms update their specifications regularly, and what was accurate in 2021 may now actively mislead you. Keep this guide bookmarked, verify dimensions against official platform documentation before major campaigns, and always design for safe zones rather than dimensions alone.
