Print preparation
Image size is the printed artwork itself. Paper size includes any surrounding border. An 8 × 10-inch image with a one-inch border on every side needs a 10 × 12-inch sheet. Check your frame’s visible opening and any mat overlap before choosing dimensions.
Only when the image’s proportions match the opening inside those borders. Otherwise, keeping the full image usually means unequal borders; keeping equal borders means cropping. White Border Builder lets you explore both approaches.
Changing a resolution label alone does not add detail. For image sizing, PPI means pixels per inch: a 2400 × 3000-pixel file prints at 8 × 10 inches at 300 PPI. DPI describes printer dots. Sharpness also depends on the source image, compression, and any previous enlargement.
300 PPI is a useful planning target for detailed prints, rather than a guarantee or a rule for every image. Larger prints, viewing distance, and materials can change what works well. Ask the studio if you’re unsure about your file.
