Off-Spec Images Can Get Cropped
Each platform has a fixed display ratio, so uploading an image sized differently from the recommendation can cause important parts to get cropped or leave unwanted white space. It helps to check a platform's recommended size before posting.
Sizes Can Change Over Time
Platforms periodically update their policies, which can shift recommended sizes slightly β for anything important, it is safer to check that platform's current guidelines before posting.
Frequently Asked Questions
Are these sizes always fixed?
Platforms update their policies periodically, which can shift recommended sizes slightly, so for important content it's safer to check that platform's latest guidelines before posting.
Is it okay to upload an image larger than the recommended size?
Most platforms will automatically resize it to fit the ratio, but for precise control over composition, it's best to crop and edit to the recommended ratio yourself before uploading.
