Ever wondered, “How Big Is a 4×6 Photo?” It’s a popular size, but what does that mean in real measurements? Whether you’re printing photos for an album, a frame, or a scrapbook, knowing the exact size helps.

A 4×6 photo is small, but it holds big memories! In this guide, I’ll explain “How Big Is a 4×6 Photo?” in simple terms. You’ll learn its size in inches, centimeters, and pixels. Plus, I’ll share why it’s so popular and how to print it right. Let’s get started!

Understanding 4×6 Photo Dimensions

A 4×6 photo size is one of the most common print sizes. How big Is a 4×6 Photo? A 4×6 photo size measures 4 inches by 6 inches (or 4 * 6 photo size in inch). In metric units, that’s 10.16 cm x 15.24 cm (4×6 photo size in cm) or 101.6 mm x 152.4 mm (4×6 photo size in mm).

The 4×6 inch photo size in pixels depends on the resolution. At 300 DPI, it is 1200 x 1800 pixels for sharp prints. At 200 DPI, it is 800 x 1200 pixels, and at 150 DPI, it is 600 x 900 pixels. Higher DPI gives better quality.

If you edit in Photoshop, set the file to 4 x 6 inches paper size with 300 DPI. Use RGB mode for digital and CMYK mode for printing.
