Why 300 DPI matters

At 300 DPI

Your cover looks crisp and professional when printed. Text is sharp, images are clear, colors are vibrant. Readers see a quality product.

Below 300 DPI

Your cover looks pixelated or blurry. Text appears fuzzy. Images have visible blocks or artifacts. Readers think it's amateurish. KDP may reject it.
