Formats & weights

  • PNG — best for sharp logos and text; use when transparency or crisp edges matter.
  • JPG — best for photographic backgrounds; save at high quality and optimise.
  • SVG — ideal for vector logos/icons; ensure fonts are outlined or embedded.

Max file size: 150 KB per creative (display). For high-res or source assets you may share larger files separately.

Colour space: sRGB, RGB only.

Accessibility & quality

  • Provide concise, descriptive alt text (e.g. “CALMSS — school-based therapeutic support”).
  • Maintain contrast ≥ WCAG AA for text over backgrounds.
  • Keep key text ≥ 14–16 px at 1x; avoid dense paragraphs in banners.
  • Leave safe padding around logos/text for responsive crops.
  • Prefer static creatives to ensure page performance and readability.
