Social Image Sizes: The Right Dimensions Before You Export
Posting the wrong size means cropping surprises. This reference table lists the commonly used dimensions per platform and placement.
What is the Social Image Sizes Calculator?
Pick a platform and a placement to see the commonly used pixel dimensions and aspect ratio for that slot. This is a reference table, not a live spec feed: platforms change their specs, so verify the size in the platform's own guide before publishing.
How to use it
- Choose a platform.
- Choose a placement.
- Click Show Sizes and check the platform's own guide before publishing.

What size is an Instagram post image?

Frequently asked questions
Are these sizes guaranteed current?
No. Platforms update specs without notice, so treat this as a reference and verify before publishing.
What if my image is larger?
Larger images at the same aspect ratio usually scale down fine; the ratio matters more than exact pixels.
