Frequently Asked Questions

DPI (Dots Per Inch) matters for printing. For screen display, only pixel dimensions matter. For printing at standard quality: 300 DPI = print size in inches × 300 pixels. For example, a 3000×2000px image prints at 10×6.67 inches at 300 DPI. Web images only need 72–96 DPI. The "300 DPI equivalent" shown is the print size at 300 DPI quality.

Aspect ratio is the width-to-height relationship, simplified to the smallest whole-number ratio. Common ratios: 16:9 (widescreen), 4:3 (traditional), 1:1 (square), 9:16 (portrait/mobile). The checker calculates this automatically. Use the Aspect Ratio Calculator tool to convert between aspect ratios and target dimensions.
