SharePoint: Header, Logo & Layout Tips

Key insights

• SharePoint site header overview: Customize the top area of modern SharePoint sites to control logo, title, layout and background.
  Access the editor via Settings > Change the look > Header. Only site owners can edit headers and header properties can inherit from a hub site.
  When no logo is uploaded, SharePoint shows a mandatory square logo thumbnail.
• Layout options: Choose from Compact (default), Standard, Minimal, and Extended layouts to change height, logo size, and navigation placement.
  Note: Minimal and Extended may be unavailable in some government clouds and will auto-transition to Compact or Standard.
• Design tab features: Add a background image, adjust overlay and opacity, and set the image focal point to control cropping and emphasis.
  Choose built-in font packages for title and navigation. Be aware of an SVG restriction on group-connected sites for image uploads.
• Logo and image guidance: Upload a primary site logo (non-square allowed) and a square thumbnail for lists and search (64x64 px).
  Recommended sizes: site logo ~192x64 px; extended banner ~2560x164 px to avoid stretching or blurry rendering.
• How to apply changes: Preview and apply edits from the Header editor to save the new header.
  The command bar hides in view mode for a cleaner experience and the built-in tools enable no-code customization by non-developers.
• Benefits and best practices: Use consistent branding, improve user experience, and keep sites uniform through hub site inheritance.
  Test header visuals in your target cloud, use recommended image sizes, and ensure a clear logo to prevent display issues.
