Image resize guides
Find image dimensions, aspect ratios, and resizing guidance for posts, stories, thumbnails, banners, and profile images.
Resizing changes an image's pixel width and height so it fits the space where it will be displayed. A square profile image, a wide video thumbnail, and a vertical story all need different proportions. These guides explain dimensions and aspect ratios, and help you avoid stretched images or unexpected crops when a platform adjusts an upload. The right starting point is the size or shape requested by the destination, not a generic preset that may not match your layout.
Use this collection when you need dimensions for a post, story, banner, avatar, thumbnail, or marketplace listing. The articles cover platform-specific size requirements as well as general questions such as preserving quality, choosing a crop, and understanding the difference between resizing and compression. When you have the target dimensions, the resizer offers templates for supported social platforms and a custom option for other sizes.
A good workflow is to make a copy of the source image, select the dimensions required by the destination, and inspect the preview before saving. If the aspect ratios do not match, decide whether to crop the image or leave space around it; stretching can distort faces, logos, and product shapes. If the resized file is still too large, use the compression guidance after the dimensions are settled. Each guide links to related formats and settings when they solve a different part of the problem.
