FAQ

Frequently asked questions

What is the best all-purpose social media image size?

1080×1080px (1:1) is the safest cross-platform size — it displays cleanly on Instagram, Facebook, LinkedIn, and Threads. For vertical Stories and Reels, use 1080×1920px (9:16).

How often do social media image sizes change?

Roughly once a year as platforms tweak their feeds. This guide is dated 2026 and reviewed against each platform's current specs.

What size should I make a profile picture?

Upload at least 400×400px square. Most platforms crop profile pictures to a circle, so keep the subject centered.

Why do my images look blurry after uploading?

The file was likely too small, the wrong ratio, or over-compressed by the platform. Export at the exact pixel size, then compress to a sensible file size before uploading.
