Frequently Asked Questions

What size should an Instagram post be?

1080 × 1080 for square, 1080 × 1350 for portrait (which occupies the most feed space) and 1080 × 1920 for stories and reels. Instagram downsamples anything larger, so 1080 pixels wide is the practical maximum.

What size is a YouTube thumbnail?

1280 × 720 pixels, a 16:9 ratio, under 2 MB. Remember it is displayed as small as 210 pixels wide in search results, so keep any text large.

What size should an Open Graph image be?

1200 × 630 pixels, a ratio of roughly 1.91:1. That is the size Facebook, LinkedIn and most chat apps use for link previews, and X accepts it for summary cards with large images.

Why does my image get cropped when I upload it?

Because its aspect ratio does not match what the platform expects, so it crops to fit — usually from the centre, cutting off whatever is at the edges. Resizing to the exact ratio first puts you in control of what gets kept.
