Image rules

Guidelines for sharp, fast-loading images in emails and on funnels or landing pages.

Email template image recommendations

Section titled “Email template image recommendations”

  • Logo: Display around 120–200 px wide; upload around 240–400 px wide for sharpness. For a typical horizontal logo, 200 × 50 px display / 400 × 100 px upload works well. Product documentation often uses a header-logo example around 50 × 200 px as a sensible display size.

  • Top banner / hero image: 600 × 200–300 px display; upload 1200 × 400–600 px. That matches the CRM’s default email width and the common email-builder guidance to use roughly 600–660 px minimum, or double that for retina screens.

  • Full-width content image: 600 px wide display; upload 1200 px wide.

  • 2-column email image: About 264–330 px wide display; upload about 528–660 px wide.

  • 3-column product/image block: About 164–220 px wide display; upload about 328–440 px wide.

  • Social icons: Show them around 24–32 px; upload 48–64 px so they stay crisp. That follows the same “upload roughly 2× the rendered size” rule used for sharp email images.

  • Email background image: Use only if really needed; keep it lightweight and roughly 1200 px wide or less. Note that larger background files load slower, and not all email clients support background images, so a fallback background color is smart.

Funnel / landing page image recommendations

Section titled “Funnel / landing page image recommendations”

  • Header / navbar logo: Usually 150–250 px wide on the page; upload roughly 2× that size. A common working file is 400 × 100 px for a horizontal logo. Product documentation uses a header-logo example around 50 × 200 px as a reasonable display size.

  • Hero image / main section image: 1600 × 900 px is a very safe working size. If you want extra headroom for large screens, use 1920 × 1080 px. The CRM recommends 16:9 images such as 1600 × 900 or 1920 × 1080 for slider-style hero visuals.

  • Image slider / gallery images: Keep every slide the same aspect ratio, ideally 16:9, using 1600 × 900 or 1920 × 1080.

  • Regular section/content image: 800–1200 px wide is usually enough for most content blocks, because sizing images close to their real display size avoids uploading giant files.

  • Team photo / testimonial avatar: 300 × 300 px or 400 × 400 px works cleanly for square profile images, with separate mobile sizing if needed.

  • Favicon: Make it square. Google says it must be at least 8 × 8 px, and recommends larger than 48 × 48 px; MDN notes 16 × 16 px is a common browser favicon size. A good workflow is to design from a 512 × 512 px master and export smaller favicon versions from it.

Best file formats

Section titled “Best file formats”

For funnel / landing page photos, use JPG or WebP; for graphics that need transparency, use PNG. The CRM media library supports common image formats including JPEG/JPG, PNG, SVG, WEBP, GIF, TIFF, and HEIC. For email images, safer/common formats in mainstream email builders are JPG/JPEG, PNG, and GIF.

Best loading rule

Section titled “Best loading rule”

If you want the fastest, smoothest setup in the CRM, use this:

  • Email full-width image: 600 px display / 1200 px upload
  • Landing page hero: 1600 × 900 px
  • Logo: upload at about 2× the display size
  • Always compress before upload
  • Avoid oversized images just because the CRM can accept them

Resize images before upload where possible—that’s the sweet spot between sharp and fast-loading. Mailchimp’s image guidance also recommends avoiding oversized files and keeping images under about 1 MB.
