Recommended Image Sizes for SureDash

When customizing your SureDash portal, using the correct image sizes ensures your design looks sharp, consistent, and professional. 

Below are the recommended dimensions for different areas of the portal.

Space Banner Image

• Recommended Size: 1920 x 600 px (updated from the old 1920 x 384 px)
• Tip: Use a wide, panoramic image with centre-focused content so important details don’t get cut off on smaller screens.

Portal Logo

• Recommended Size: 300 × 75 px (rectangular)
• Alternative (for icon logos): 512 × 512 px
• Tip: Transparent PNGs work best. Use the rectangular size for header-style layouts, and square only if your logo mark fits that shape.

Portal Favicon

• Recommended Size: 64 x 64 px
• Tip: Keep it simple and recognizable, since favicons are displayed small in browsers.

User Profile Picture

• Recommended Size: 98 × 98 px
• Tip: Use a clear portrait or brand graphic. It’s displayed in a small circular frame, so keep it simple.

Profile Cover Image

• Recommended Size: 728 × 292 px
• Tip: Use a wide image with the main subject centered. This area displays behind the user’s profile details, so avoid placing important text near the edges.

Space Thumbnails (Grid/List views)

• Recommended Size: 1200 x 675 px
• Tip: Similar to social media share previews. Works well for clean titles or illustrative images.

Post / Discussion Thumbnails

• Recommended Size: 800 x 266 px
• Tip: This size works well when sharing articles, discussions, or posts inside spaces.

Create Perfectly-Sized AI Images (Nano Banana or ChatGPT)

AI tools like Nano Banana don’t always follow size instructions from text alone.
To make sure your generated images are the correct size, here’s the trick:

Upload a blank image in your desired dimensions as a reference.

 The AI will then generate your design within that size.

This method helps the AI “lock” onto the right aspect ratio, just as Adam Preiser explained in the community.
