This article outlines recommended image sizes, formats, and display behavior across the Guusto platform. Following these guidelines helps ensure your images appear sharp, properly aligned, and consistent across web, mobile, and email experiences.
Why this matters
Using correctly formatted images will help you:
Avoid distortion, cropping, or blurriness
Ensure consistent branding across your workspace
Improve how content appears in emails and feeds
Reduce formatting issues and rework
How image sizing works
Image “dimensions” in this guide refer to display container sizes, not upload limits.
Images are automatically scaled to fit their container
Aspect ratio is always preserved
The largest dimension (width or height) is constrained
Example:
An image that is 200 × 100 pixels inside a 50 × 50 container will display as 50 × 25 pixels.
