Calculate depth of field from aperture, focal length, sensor size, and subject distance. See near and far focus limits for sharp photos.
Calculate correct exposure with the exposure triangle. Set ISO, aperture, and shutter speed for balanced photos in any lighting situation.
Convert focal length between camera sensor sizes using crop factor. Find full-frame equivalent focal length for APS-C, MFT, and more.
Divide pixel count by DPI to get print size in inches. Higher DPI yields smaller but sharper prints; lower DPI allows larger prints with softer detail.
Print width (in) = pixel width / DPI300 DPI is standard for close-viewing photo prints; 150–200 DPI suits large posters viewed from a distance; canvas wraps often use 100–150 DPI.
Max size = pixels ÷ DPIUpscaling in software adds interpolated pixels but not real detail. Stay within 1.5–2× native resolution for acceptable large-format output.
Megapixels = (width × height) / 1,000,000Updated: July 2026
4000 × 3000 pixels at 300 DPI yields roughly 13.3 × 10 inches — an 8×10 crop fits comfortably with room to spare.
6000 × 4000 pixels at 150 DPI prints up to 40 × 26.7 inches — suitable for wall art viewed from several feet away.
A 4032 × 3024 image exceeds 300 DPI at 4×6 inches, making small prints sharp even from mobile cameras.
Screens use 72–110 PPI; prints need 150–300 DPI depending on size and viewing distance. Always use print-appropriate DPI values.
Maximum dimensions from pixels may not match 8×10 or 16×20 ratios. Plan crops or borders so important content is not cut off at standard print sizes.
Image pixel dimensions and target print resolution (DPI) determine how large you can print before pixels become visible. Enter width, height, and desired DPI to find maximum print size in inches or centimeters.
