Prismic Preview Asset Standards

This skill governs the creation and optimization of preview images for Prismic Slices and Custom Types. Use these guidelines to ensure the Page Builder remains performant and visually cohesive for content editors.

📐 Image Dimensions & Scaling

To ensure components look crisp in the Prismic UI without causing interface lag:

  • Optimal Size: 2000 x 1200 pixels.
  • Minimum Size: 800 x 600 pixels (avoid smaller to prevent pixelation).
  • Aspect Ratio: Always favor Landscape (16:9 or 3:2).
    • Note: Vertical images result in significant letterboxing within the wide-format Page Builder list.

⚙️ Technical Specifications

  • File Formats: Use .png or .jpeg.
  • File Weight: Aim for 200KB – 500KB.
    • Rationale: Heavy images degrade the performance of the Slice Machine and Page Builder interface.
  • Capture Method: Prioritize the Slice Machine "Screenshot" button to capture local development components at high resolution (~2300px wide).
