Image size and resolution for social media
You upload a carefully shot photo to Instagram and it shows up blurry, with weird patches or pixelated. Frustrating. The size and resolution of images for social media decide whether your content looks professional or sloppy, and almost nobody gets it right on the first try. Here's what you need so your photos come out sharp on any platform.
Why your photos come out blurry on social
Every network compresses the images you upload brutally to save space on their servers. That compression is what wrecks your designs: you get patches, blur and pixelated edges. It's not your camera's fault, it's the platform's recompressor.
The way to beat it is to upload the image already optimized at the exact size each network asks for, so the algorithm touches it as little as possible.
The sizes that work in 2026
Each format has its ideal size. Upload an image in the right ratio and the network recompresses it less:
- Instagram square: 1080×1080 px (1:1 ratio).
- Instagram vertical / feed: 1080×1350 px (4:5), the format that takes up the most screen space.
- Stories and Reels: 1080×1920 px (9:16).
- Facebook post: 1200×630 px.
- LinkedIn post: 1200×627 px.
- Covers / headers: check each network's current size, they change often.
Correct weight, resolution and format
Beyond dimension, control these three settings and you'll notice the difference:
- Resolution: between 72 and 96 dpi. You don't need more on social; what counts is the pixel dimension.
- Weight: aim for around 100 KB when you can. The lighter the image goes in, the less the compression crushes it.
- Format: JPEG for photos, PNG for graphics with flat colors, text or vector compositions.
- Color profile: RGB, never CMYK. That's the classic mistake from people coming from print: CMYK looks dull and shifts colors on screen.
Tools to get them ready
You don't need Photoshop for this. With Canva you get each network's sizes already set as templates, and with GIMP (free) you control size, weight and format in detail. Always export to the platform's exact size before uploading.
Taking care of the size and resolution of your social media images isn't a designer's whim: a sharp photo signals there's a business behind it that cares, and that drives more engagement and more trust. It's the same standard we apply to the brand and content management of our clients.
Frequently asked questions
1080×1080 px for square, 1080×1350 px for vertical (4:5), and 1080×1920 px for stories and reels. Uploading the exact size reduces compression and improves sharpness.
Because every network compresses images to save space. If you upload the photo already optimized at the right size and weight, the platform recompresses it less and it looks better.
Between 72 and 96 dpi, in JPEG for photos and PNG for flat graphics, always in RGB color profile (never CMYK).
