How Big Can I Print My Photo? (Pixels & Megapixels to Inches Chart)
Divide your photo's pixel width and height by 300 (fine art) or 150 (canvas) to find your exact maximum print size—plus when to use 4× browser upscaling.
Technician Summary (The Short Version)
- •The formula is simple: Print Inches = Pixels ÷ DPI.
- •A 12 MP iPhone/Android photo (3024 × 4032 px) prints at 10×13" at 300 DPI, 15×20" at 200 DPI, and 20×26" at 150 DPI.
- •Text messaging apps (SMS, WhatsApp, Messenger) strip photos down to 1–2 MP. Always transfer the original camera roll file via AirDrop, USB, or cloud link.
