Social Media Post Sizes Cheat Sheet by Platform

Overview

If you regularly publish to Instagram, Facebook, LinkedIn, X, or TikTok, you already know the problem: the file that looks right in your design tool can look cropped, padded, or oddly framed once it goes live. A dependable social media size guide helps, but the more durable solution is to pair current dimensions with a template system.

Based on current 2026 guidance from Hootsuite’s platform roundup, a few patterns are stable enough to treat as defaults. First, 1080 pixels wide remains a practical baseline for many feed and full-screen formats. Second, vertical and mobile-first aspect ratios, especially 4:5 and 9:16, tend to work better than older square-first habits on most networks. Third, profile and cover images still need platform-specific handling because display behavior varies more than standard post slots.

Here is the working cheat sheet most creators will need most often:

• Instagram: profile 320 x 320 px; landscape post 1080 x 566 px; portrait post 1080 x 1350 px; square 1080 x 1080 px; Stories/Reels 1080 x 1920 px
• Facebook: profile 196 x 196 px; landscape post 1080 x 566 px; portrait post 1080 x 1359 px; square 1080 x 1080 px; Stories/Reels 1080 x 1920 px; cover 851 x 315 px
• X: profile 400 x 400 px; landscape post 1280 x 720 px; portrait post 720 x 1280 px; square 720 x 720 px; cover 1500 x 500 px
• LinkedIn: profile 400 x 400 px; landscape post 1200 x 627 px; portrait post 720 x 900 px; square 1200 x 1200 px; cover 1128 x 191 px
• TikTok: profile 20 x 20 px listed in source guidance, though in practice higher-resolution source files are safer; vertical post 1080 x 1920 px; Story 1080 x 1920 px; landscape ad 1920 x 1080 px; square ad 640 x 640 px

Those numbers are the reference. The bigger editorial point is how to use them. Rather than designing every post from scratch, build a compact system of master files around the formats you publish most: square feed, vertical feed, story/reel, landscape card, cover image, and carousel slide. This approach saves time, protects visual consistency, and makes it easier to swap in design assets like icons, illustration packs, background textures, and branding mockups without constantly reworking the layout.

One useful caution from the source material: not every platform displays uploaded images exactly as designed in every context. Instagram is a clear example, where different post orientations can appear one way in-feed and another way on the profile grid. X cover images can also display differently depending on browser and monitor. The safest evergreen interpretation is simple: design to the recommended upload size, but keep critical text and logos away from edges and likely crop zones.

Template structure

A cheat sheet becomes much more valuable when it turns into a template library. The most efficient template structure is not one file per post, but one system with a few standardized artboards, safe areas, and modular layers.

Start with six master canvases:

1. Portrait feed: 1080 x 1350 px for Instagram-first posting
2. Square feed: 1080 x 1080 px for cross-platform reuse
3. Story/Reel vertical: 1080 x 1920 px
4. Landscape feed/card: 1200 x 627 px or 1280 x 720 px depending on your main destination
5. LinkedIn or X cover: dedicated cover files, never repurposed from post templates
6. Carousel slide set: usually square or portrait, depending on your primary platform

Within each master, use the same internal layer structure so anyone on your team can open and edit it quickly. A practical setup looks like this:

• Background layer: solid color, gradient, photo, or texture
• Image or illustration layer: product image, editorial photo, mockup, or vector graphic
• Headline group: main message, subhead, and optional label
• Brand group: logo, URL, handle, or campaign mark
• CTA group: swipe prompt, save/share prompt, or campaign tag
• Safe area guides: non-exporting overlays marking crop-sensitive zones
• Export notes: filename convention, destination platform, and version date

Safe areas matter more than many size charts suggest. A template that uses the full canvas is often technically correct but visually fragile. For story and reel graphics, keep the main text away from the top and bottom UI-heavy regions. For profile and cover images, assume some variation in desktop and mobile display. For Instagram portrait posts, remember that the feed and grid can emphasize different crops, so your focal point should sit comfortably within the center of the design.

A strong template also separates content from decoration. If your headline, product image, and CTA depend on a very specific composition, the file will be hard to adapt. Instead, treat design assets as modular components. Use icon sets for category markers, illustration packs for recurring campaign themes, and background textures for visual depth, but keep these elements swappable. This is especially helpful when building social media templates for recurring series such as weekly tips, event announcements, product drops, and quote cards.

If you want your files to stay useful over time, label them by function rather than by campaign. “IG-Feed-Portrait-Quote-v1” is better than “March Launch 3 final final.” Good naming is not glamorous, but it is one of the easiest workflow improvements you can make.

How to customize

The easiest mistake with a social media size guide is treating every platform as if it needs completely different creative. In practice, most teams do better with a shared visual system and a small number of platform-specific adjustments.

Begin with your primary publishing format. If your audience is mostly on Instagram and TikTok, build from portrait and 9:16 first. If your content performs best on LinkedIn, start with square and landscape. Then map each content type to its most natural frame:

• Announcements: square or portrait for feed visibility
• Educational tips: carousel or portrait
• Video promos: 9:16 for stories, reels, and TikTok
• Thought leadership or article shares: LinkedIn landscape or square
• Brand headers: platform-specific cover dimensions

Next, decide what should stay fixed across platforms. Usually this includes type styles, brand colors, icon language, spacing, and the position of recurring elements such as logos or category tags. What changes is often the crop, image scale, and amount of copy. Vertical formats can carry more stacked text; horizontal formats usually need shorter lines and clearer hierarchy.

Here are a few practical customization rules that keep templates flexible:

1. Design headline-first. If the message does not fit the format cleanly, the template is too rigid.
2. Use one focal point. On small screens, one image or one illustration usually outperforms a crowded collage.
3. Limit edge-dependent details. Borders, tiny corner logos, and bottom-aligned captions are more likely to crop badly.
4. Build alternate text blocks. Have short, medium, and long headline styles ready.
5. Create background options. Include plain color, photo, gradient, and texture versions for quick swaps.

This is where well-organized design assets become useful instead of decorative clutter. A compact set of icons templates mockups, illustration packs, and texture packs can extend one template system into many campaigns without making the brand feel inconsistent. If you rely on vector-based elements, you can resize them across portrait, square, and story formats with less quality loss than raster-only graphics.

For creators who need commercially usable graphic design assets without rebuilding every post manually, a small internal library beats a huge unorganized folder. Keep only the assets you actually use: a few icon families, a consistent set of background textures for designers, several editable social media templates, and any branded mockup elements that support launches or portfolio posts.

Examples

The best way to use this cheat sheet is to build repeatable template families instead of one-off files. Here are four examples that show how current social media post dimensions can drive a cleaner workflow.

1. The cross-platform promo set

Create one campaign in four sizes: 1080 x 1350, 1080 x 1080, 1080 x 1920, and 1200 x 627. Use the same background, headline, and key visual, then adjust the crop and text density. This gives you an Instagram portrait post, a universal square card, a story version, and a LinkedIn-friendly landscape share. For most teams, this is the highest-return starter pack.

2. The quote or tip carousel

Use a square or portrait format depending on your primary platform. Build a cover slide, content slide, stat slide, and CTA slide using the same margins and hierarchy. Keep page numbers and small labels inside a conservative safe area. If the same content needs to become a story sequence later, the text can be reformatted into 1080 x 1920 without changing the visual language.

3. The cover-and-profile refresh

Cover images deserve their own templates because they are displayed differently across platforms. X uses a 1500 x 500 cover, Facebook uses 851 x 315, and LinkedIn uses 1128 x 191. These are not interchangeable. The safest method is to keep one background image and one message system, then crop separately for each platform. Avoid placing important text at the far edges, and do not assume the desktop view is the only one that matters.

4. The vertical-first launch pack

If your strategy leans into reels, stories, and TikTok, start with 1080 x 1920 and adapt downward from there. Build a top-safe headline zone, a center focal area, and a lower CTA area that stays clear of interface overlays. Then export still graphics, motion slides, or short video covers from the same base file. This keeps brand consistency strong while matching mobile-first viewing habits.

To sharpen visuals for these formats, it helps to pull from cohesive creative assets rather than random stock folders. Textures, architectural surfaces, and bold lighting references can be especially effective for social campaigns with a modern editorial feel. Our guide to Photographing Brutalist Buildings: A Creator’s Guide to Lighting, Angles, and Textures is a good reference if you want to build stronger custom backgrounds or source images with a more deliberate graphic quality.

And if your brand language leans minimal, restrained, or structural, Concrete Confidence: How Gangnam Brutalism Shapes Modern Minimal Brand Identity can help you translate those visual ideas into repeatable social templates.

When to update

A size chart is only evergreen if you treat it as a living reference. The dimensions above are useful now, but your workflow should assume that platforms will revise display behavior, new post formats will appear, and older placements will matter less over time.

Revisit this cheat sheet when any of the following happens:

• A platform changes cropping or grid display. Instagram grid behavior is a common trigger because it affects how portrait and square posts appear in profile.
• You add a new publishing channel. A LinkedIn-first workflow is not the same as a TikTok-first workflow.
• Your design tool changes. Moving from Photoshop to Canva or Figma often changes how templates, shared libraries, and exports are managed.
• You start using more video or motion. Static post templates may need 9:16 variants with motion-safe zones.
• Your team publishes more frequently. More volume usually means template simplification becomes more important than visual experimentation.

A practical maintenance routine looks like this:

1. Audit your top five social templates every quarter.
2. Check current recommended dimensions for each destination platform.
3. Open your master files and confirm that safe areas still make sense.
4. Test one post in the live environment before updating the whole library.
5. Archive old sizes rather than deleting them immediately, in case campaigns still reference them.

If you maintain downloadable design assets or internal brand asset packs, add the update date to the template name or cover page. That single habit reduces confusion for future collaborators and makes it easier to tell whether a file is still current.

The broad lesson is simple: social media post dimensions are not just technical specs. They shape how a message is framed, how a visual hierarchy reads on mobile, and how reusable your template library becomes. Keep a short list of current dimensions close at hand, build around a few reliable master canvases, and refresh those files whenever platform behavior or your publishing workflow changes. That is the version of a social media size guide that stays worth revisiting.
