Frequently Asked Questions

What size should a WordPress featured image be?
1200x628 pixels is the best universal size. It matches the Open Graph (OG) image ratio used by Facebook and LinkedIn when your post is shared, and works well with most WordPress themes.
Does featured image size affect SEO?
Indirectly, yes. Large, unoptimized images slow down page load times, which hurts SEO. Use properly sized and compressed featured images. Also add descriptive alt text for accessibility and image search rankings.
Why does my featured image look different on social media?
Social platforms crop images to their own ratios. Facebook and LinkedIn use 1.91:1 (which matches 1200x628). Twitter uses 2:1. Using 1200x628 gives the best results across most platforms.
Should I use the same image size for all WordPress posts?
Yes, consistency is important. Using the same dimensions for all featured images ensures your blog page, archives, and related post grids look clean and professional.
