Social Media Image Size Guide (2026)

Updated August 11, 2026

Why image size matters on social media

Every social platform displays images at specific dimensions. Upload the wrong size and the platform crops it — often badly, cutting off faces or text — or stretches it until it looks unprofessional. Sizing an image correctly before you upload puts you in control of exactly what is shown.

Below are the current recommended dimensions for the main platforms. Resize any photo to these exact dimensions with the image resizer, or crop it to the right shape first with the image cropper — both run in your browser.

Instagram

Image Dimensions
Square post 1080 x 1080
Portrait post 1080 x 1350
Story or Reel 1080 x 1920

Portrait posts take up more feed space than square ones, which is why many creators prefer them.

YouTube

Image Dimensions
Video thumbnail 1280 x 720
Channel banner 2560 x 1440

The channel banner is shown at different crops on phone, desktop, and TV, so keep important elements near the center.

X (Twitter)

Image Dimensions
Header banner 1500 x 500
In-feed post image 1200 x 675

Facebook, LinkedIn, TikTok, and Pinterest

Image Dimensions
Facebook cover photo 820 x 312
LinkedIn profile banner 1584 x 396
TikTok video 1080 x 1920
Pinterest pin 1000 x 1500

Two tips for sharp social images

  1. Start from a large source. Crop your photo to the target's shape first with the image cropper, then resize it to the exact pixels. Starting from a photo larger than the target keeps the result sharp — enlarging a small image looks soft.
  2. Mind the file size. Platforms re-compress what you upload, but a smaller starting file uploads faster. If needed, run the result through the image compressor.

Dimensions do shift as platforms redesign, but the sizes above reflect current guidance. When in doubt, a larger image at the right aspect ratio is always safer than a small one.

Frequently asked questions
