What is the main difference when comparing 4×6 vs 5×7 photo sizes?

When comparing 4×6 vs 5×7, the main difference is size and visual impact. A 4×6 photo is more compact and commonly used for everyday prints, while a 5×7 photo offers more space for details. Visuals Clipping discusses that 5×7 prints work better for framing and gifting. Meanwhile, 4×6 remains a practical option for albums and bulk printing. The larger 5×7 size also allows facial expressions and textures to appear clearer.
