Digital Toolbox

Blueprint for Social Media Image Sizes

A pixelated, poorly cropped image reads as sloppy craftsmanship, the same as a bad cut ruins a piece of timber. Every platform below crops differently, and the difference between a sharp post and a stretched one usually comes down to uploading the wrong pixel count, not the wrong photo.

Meta now prioritizes 4:5 vertical posts over the square crop it pushed for a decade: a portrait image simply takes up more of a phone screen than a square one, and Meta's own 2026 ranking signals favor it. That single shift is why almost every number below skews taller than it used to.

This page gets updated whenever the specs move, not left to go stale. Below is the current, field-tested reference for your digital toolkit, stripped of the fluff.

A 1080 by 1080 square post compared to the taller 1080 by 1350 portrait post that now outperforms it in feed 1:1, old default 1080×1080 4:5, current default 1080×1350
Same width, more height. The 4:5 crop on the right claims roughly 25% more vertical space in a mobile feed than the square crop on the left ever did.
Five common image aspect ratios, drawn to scale, from tall 9:16 Stories to wide 1.91:1 social previews 9:16 1080×1920 4:5 1080×1350 1:1 1080×1080 16:9 1920×1080 1.91:1 1200×630
Five ratios, drawn to true relative scale: Stories, a vertical feed post, a square post, a 16:9 hero, and a 1.91:1 social preview.

1. Instagram

2. Facebook

3. LinkedIn

4. X (formerly Twitter)

5. TikTok & YouTube

6. Threads & Pinterest

Threads rides on Instagram's image pipeline, so nothing here is a new number to learn: reuse Instagram's 1080×1350 for a feed post and 1080×1920 for a full-screen image. Pinterest is the one platform still built around tall pins rather than square or 4:5 crops.

The Long Game

The Strategy for Lasting Impact

Do not chase every minor layout alteration with panic. Instead, construct a blueprint around sturdy foundations. Establish baseline assets at 1080px wide for mobile feeds, use clean PNG formats for text-based graphics, and routinely check how your imagery renders across desktop and mobile.

The Common Standards

Most modern site platforms and social media crawlers favor these three ratios:

RatioBest ForCommon Resolution
16:9Standard featured images, hero sections, YouTube thumbnails1920 × 1080
4:3Older blog layouts, photography-heavy sites1200 × 900
1.91:1Social “Open Graph” previews (Facebook, LinkedIn, X)1200 × 630

Why 16:9 Wins

  • Device compatibility: most screens (laptops, TVs, and phones in landscape) are natively 16:9
  • The fold: wide enough to be featured without pushing all your text content below the fold
  • Social previewing: a 16:9 image rarely crops awkwardly on Facebook or LinkedIn. They’ll just shave a few pixels off the top and bottom to hit their 1.91:1 requirement

Technical Best Practices

Beyond just the shape, keep these golden rules in mind to keep your site fast and pretty:

Whatever the ratio, keep the width at 1200px or wider: the floor for Google Discover and for a full-size social card.

The “Hero” Exception

If your featured image is a hero background (an image that spans the entire top of the page with text over it), ratios matter less than focal points. In these cases, use a wider ratio like 21:9 or 3:1 to prevent the image from taking up the entire vertical screen on a laptop.

Pro tip: check whether your site platform forces “hard cropping.” Some will force whatever you upload into a specific ratio, which can lead to some accidental “headless” team photos.

Getting the dimensions right is the easy part. Keeping a consistent posting schedule on top of it is where most small businesses run out of hours in the week. If that’s where you’re stuck, see how social media management works, or get in touch and we’ll take it off your plate.
