Image Size Reference Table

A raster image is a pixel-based graphic, and resizing refers to changing that pixel grid for a new destination. The table below compares common presets so it is easier to choose the smallest dimension that still matches the platform you are targeting.

Frequently Asked Questions

What is the difference between resizing and cropping?

Resizing changes the pixel dimensions of the image, while cropping removes part of the frame to fit a target shape or aspect ratio.

When should I keep the aspect ratio?

Keep the aspect ratio when you want to avoid stretching people, products, or interface screenshots.

Why do social media presets matter?

Preset dimensions reduce platform-side cropping so the image looks closer to your intended composition.

Can a resized image still look sharp?

Yes, if the output dimensions fit the destination and you avoid extreme upscaling beyond the source resolution.
