Best Image Sizes for Social Media in 2026

Why Do Social Media Image Sizes Matter?

Are you wondering what is the best size for social media post graphics? Every platform is different. If your photo is too big or too small, the app will stretch it, blur it, or cut off the most important parts. Using the best size for social media posts ensures your profile looks clean, professional, and gets you more likes and shares.

Instagram Image Sizes

Instagram loves square and tall photos because most people use it on their phones.

• Profile Picture: 320 x 320 pixels. Try our Crop Image Tool to make an exact circle for your avatar.
• Square Post: 1080 x 1080 pixels. Need to fix a photo? Use our Instagram Resizer.
• Stories & Reels: 1080 x 1920 pixels.

Facebook Image Sizes

Facebook needs good photos for both pages and groups.

• Profile Picture: 170 x 170 pixels.
• Cover Photo: 820 x 312 pixels. If your camera takes massive photos, shrink them with the Image Resizer first.
• Shared Post: 1200 x 630 pixels.

LinkedIn Image Sizes

LinkedIn is for professionals. Cloudy or messy pictures look very bad here.

• Profile Picture: 400 x 400 pixels.
• Background Cover: 1584 x 396 pixels. Backgrounds have strange dimensions, so using a Cropper is highly recommended.
• Article Image: 1200 x 627 pixels. Keep file sizes small using the Image Compressor so the page loads fast.

X (Twitter) Image Sizes

Twitter moves fast. Images that stay in the center get the best results.

• Profile Photo: 400 x 400 pixels.
• Header Image: 1500 x 500 pixels.
• In-stream Photo: 1600 x 900 pixels. Twitter can break heavy pictures, so dropping them under 2MB by compressing to 200KB helps a lot.

Conclusion

No matter which platform you use, starting with high-quality, correctly sized images is the easiest step to growing your page. Instead of fighting with complex software, you can just use a Bulk Image Resizer to process a whole folder of posts at once!
