Social platforms quietly tweak their image specs every year, and 2026 is no exception. In this guide, RichAds ad network’s team gathers current social media poster size requirements for ten platforms.
Plus, there’s a consolidated reference table, built for affiliate teams who’d rather check one page than ten when prepping creatives.
Wrong dimensions kill creatives before anyone clicks. Most affiliate teams already pair organic social with paid networks like the RichAds advertising network, which covers push, pop, Telegram mini apps, native, direct click, and pre-roll video ads. But social-native sizes still matter for pre-landing pages, organic warmup posts, and the dozen creative variants every campaign chews through.
Here’s what’s inside:
- The five aspect ratios that cover roughly 95% of social placements.
- Current social media post size and social media banner sizes across ten platforms.
- One consolidated reference table covering every placement type.
- Source links to every platform’s official spec page.
Why social media post size still matters in 2026
Post size matters because platforms reward creatives at native dimensions, and mobile feeds crop anything that doesn’t fit. Pixel discipline moves CTR more than most teams realize.
A few things are pushing this in 2026. Platforms now crop and compress off-spec uploads aggressively. Mobile dominates feed sessions, which makes 9:16 the default battlefield. And every “ideal” size is a moving target.
Social media image sizes shift with each algorithm tweak, and visual content built last quarter may already be off-spec. Meta quietly shifted feed priority from 1:1 square to 4:5 portrait around 2022 to 2023, giving creators more vertical real estate.
Here’s the catch. Building four or five social media post dimensions per concept eats design hours, but skipping the variants leaves performance on the table.

The ratio cheatsheet: 1:1, 4:5, 9:16, 16:9, 1.91:1
Five aspect ratios cover roughly 95% of social placements. Pick the right social media ratio for each placement and you can size any creative without opening a spec page.
| Ratio | Orientation | Where is it used? | Is it useful in 2026? |
| 1:1 | Square | Ad networks, cross-platform fallback | The old workhorse, fading in mobile feeds |
| 4:5 | Portrait | Feed posts on Instagram, Facebook, LinkedIn, Threads | Default for feeds, biggest mobile real estate |
| 9:16 | Vertical | Stories, Reels, Shorts, TikTok, Spotlight, Snap | Full-screen mobile standard |
| 16:9 | Horizontal | YouTube long-form, in-stream video, desktop video players | Landscape default |
| 1.91:1 | Landscape | Link ad cards, Open Graph previews, FB/IG link units | The link card standard |
Anything else, like cover photos, profile pics, and the rest of the social media banner sizes you’ll need, lives in the platform sections below.
Post sizes for every platform
Numbers below are current as of 2026, cross-checked against each platform’s official spec docs. For paid traffic on the RichAds ad network, ad formats run on fixed slot dimensions. Push, pop, Telegram mini apps, native, and direct click all use predefined slots rather than custom uploads.
Facebook banner sizes
Facebook mixes legacy cover crops with feed-first specs.
- Profile photo: 320×320 px, displays as a 176×176 circle on desktop and a 196×196 circle on mobile.
- Cover photo: 851×315 px upload, with a minimum size of 400 × 150 px. Keep brand elements centered.
- Feed post: 1080×1080 px (1:1) or 1080×1350 px (4:5).
- Stories and Reels: 1080×1920 px (9:16).
- Event cover: 1920×1005 px (1.91:1).
- Single-image link ad: 1200×630 px (1.91:1).

4:5 portrait now outperforms 1:1 on organic reach.

Instagram banner sizes
Instagram is the most dimension-sensitive platform in the deck.
- Profile photo: 320×320 px upload, crops to a circle.
- Feed post (square): 1080×1080 px (1:1).
- Feed post (portrait): 1080×1350 px (4:5). The dominant feed format in 2026.
- Stories and Reels: 1080×1920 px (9:16).
- Carousel: all slides locked to the first slide’s ratio, ideally 1080×1080 or 1080×1350.

Design at 4:5 and crop down if you need a square for the profile grid.

X/Twitter banner sizes
X keeps tweaking the profile UI, but image specs stay stable.
- Header: 1500×500 px (3:1). Crops differently on mobile and desktop.
- Profile photo: 400×400 px (1:1).
- In-feed image: 1600×900 px (16:9) or 1080×1080 px (1:1).
- Promoted post image: 1200×675 px (16:9).

X compresses aggressively above 5 MB, so pre-compress to under 1 MB at 85 to 90% quality before upload.

LinkedIn banner sizes
LinkedIn runs two completely different cover specs depending on profile type.
- Personal profile photo: 400×400 px (1:1).
- Personal cover: 1584×396 px (4:1).
- Company logo: 300×300 px.
- Company cover: 1128×191 px (5.9:1).
- Feed post: 1200×1200 px (1:1) or 1080×1350 px (4:5).
- Link share image: 1200×627 px (1.91:1).

The personal cover safe zone is narrower than it looks because the profile photo blocks the right side.

Pinterest banner sizes
Pinterest is the lone holdout where 2:3 still rules.
- Profile photo: 165×165 px (1:1).
- Cover photo: 800×450 px minimum (16:9).
- Standard pin: 1000×1500 px (2:3).
- Idea pin and video pin: 1080×1920 px (9:16).

The algorithm actively limits distribution for low-resolution images and anything taller than 1500 px. Copy-pasting Instagram 4:5 creatives here costs you real estate.

Snapchat banner sizes
Snapchat is full-screen vertical end-to-end. Every ad placement uses the same dimensions.
- Snap Ads, Spotlight, Story Ads: 1080×1920 px (9:16).
- Profile icon: 320×320 px minimum (1:1).

Keep text and CTAs away from the top 150 px and bottom 330 px where UI overlays sit. Rarely a top affiliate channel, but worth the specs for spend tests.

YouTube banner sizes
YouTube’s biggest trap is the channel art safe zone.
- Profile photo: 800×800 px (renders as a 98×98 circle).
- Channel art upload: 2560×1440 px (16:9).
- Channel art safe zone: 1546×423 px center stays visible on every device, including TVs and tablets.
- Video thumbnail: 1280×720 px (16:9), max 2 MB.
- Shorts: 1080×1920 px (9:16).

Most channels make the mistake of stretching text across the full 2560 width and watching it vanish on mobile.

TikTok banner sizes
TikTok is uncompromisingly vertical. Every surface runs the same ratio.
- Profile icon: 200×200 px minimum (1:1).
- In-feed video: 1080×1920 px (9:16).
- Spark Ads: inherit the source post’s ratio.
- TopView and brand takeovers: 1080×1920 px (9:16).

The real spec is the safe zone. Keep critical content in the central area of the canvas. The top 150 px carry the username, the bottom 440 px are taken by caption and CTA, and the right 120 px hold the action rail.

Google Business Profile banner sizes
Often forgotten in social plans, but it’s the first thing a branded-search visitor sees.
- Logo / profile photo: 720×720 px ideal, 250×250 px minimum.
- Cover photo: 1080×608 px (16:9).
- Post image: 1200×900 px (4:3).

Google crops images differently on Maps and Search, so leave breathing room on the edges.

Threads banner sizes
Threads borrows Instagram’s conventions almost wholesale, with a few small twists.
- Profile photo: 320×320 px (1:1).
- Feed post (square): 1080×1080 px (1:1).
- Feed post (portrait): 1080×1350 px (4:5).
- Link card: 1200×600 px (2:1 ratio).

Cross-posting from Instagram works one-to-one. Text-only posts still outperform images on reach in 2026.

Worth remembering
Keep one master template per ratio (1:1, 4:5, 9:16, 16:9, 1.91:1) and rebuild it whenever a platform ships spec changes.
For affiliates running RichAds traffic, whether push, pop, native, direct click, or the increasingly popular Telegram mini apps, the spec list is much shorter. That’s part of why paid networks scale faster than organic-social creative pipelines.

FAQ
The 2026 default is 1080×1350 px (4:5) for feed posts and 1080×1920 px (9:16) for verticals. Teams running RichAds alongside organic usually keep one template per ratio and update it quarterly.
Most 2026 specs for social media post size in pixels converge on 1080 px on the shortest side for feed posts, 1080×1920 px for full-screen verticals, and 1200×627 px for link cards. The RichAds advertising network recommends keeping a 1080-wide master template as the safest baseline. Full breakdown in the table above.
Five ratios cover almost everything. Use 4:5 for feed posts, 9:16 for Stories and Reels, 16:9 for YouTube, 1:1 as a fallback, and 1.91:1 for link cards. Affiliate teams scaling on the RichAds ad network usually map these to a small set of master templates per campaign.
No single standard exists. Common 2026 covers include Facebook 851×315, X 1500×500, LinkedIn personal 1584×396, and YouTube 2560×144. The RichAds advertising network and other paid platforms skip this entirely since ad formats use platform-defined slots.
