Facebook Image Requirements

Facebook's image requirements have evolved significantly in 2025, especially with the platform's renewed focus on community building and local business features. Here's what you need to know:

Facebook Post Dimensions:

• Shared Image: 1200 x 630px (1.91:1 aspect ratio)
• Cover Photo: 1200 x 315px (mobile: 1200 x 675px)
• Profile Picture: 360 x 360px (displays at 170 x 170px)
• Event Cover: 1920 x 1080px (16:9 aspect ratio)

"The key to Facebook success in 2025 is understanding that the platform prioritizes authentic, community-focused content. Your visuals should reflect real moments and genuine connections."

// Dynamic Facebook image sizing function
function optimizeForFacebook(imageType, originalWidth, originalHeight) {
  const facebookSizes = {
    post: { width: 1200, height: 630, ratio: 1.91 },
    cover: { width: 1200, height: 315, ratio: 3.81 },
    profile: { width: 360, height: 360, ratio: 1 },
    event: { width: 1920, height: 1080, ratio: 1.78 }
  };
  
  const targetSize = facebookSizes[imageType];
  if (!targetSize) return null;
  
  // Calculate optimal dimensions maintaining aspect ratio
  let newWidth, newHeight;
  const originalRatio = originalWidth / originalHeight;
  
  if (originalRatio > targetSize.ratio) {
    // Image is wider than target
    newHeight = targetSize.height;
    newWidth = Math.round(newHeight * originalRatio);
  } else {
    // Image is taller than target
    newWidth = targetSize.width;
    newHeight = Math.round(newWidth / originalRatio);
  }
  
  return {
    width: Math.min(newWidth, targetSize.width),
    height: Math.min(newHeight, targetSize.height),
    cropNeeded: newWidth > targetSize.width || newHeight > targetSize.height
  };
}

// Usage example
const result = optimizeForFacebook('post', 1920, 1080);
console.log('Optimized dimensions:', result);
