Common LinkedIn Sizing Mistakes

Unprofessional Header Images

Using casual or low-quality images in headers undermines your professional credibility. LinkedIn headers should be polished and professional.

Wrong Aspect Ratios

Images that don't match LinkedIn's expected ratios get cropped automatically, often cutting off important elements like text or logos.

Overly Promotional Posts

While properly sized images are important, overly sales-focused content performs poorly on LinkedIn compared to educational or thought leadership content.

Mobile Ignorance

Many LinkedIn users access the platform on mobile. Always ensure your resized images look professional on smaller screens.
