The working
Pixels are inches multiplied by the resolution.
- Width: 5.5 in × 600 = 3,300, which rounds to 3300 pixels.
- Height: 8.5 in × 600 = 5,100, which rounds to 5100 pixels.
Bleed is extra image past the trim line, so that a cut that lands slightly off still leaves ink to the edge. Print shops usually ask for 0.125 in on every side of a US size, which makes the file 3450 × 5250 pixels.
Is your photo big enough?
To fill Half Letter at 600 DPI an image needs at least 3300 × 5100 pixels. Cropped to fill the sheet:
- A 12 megapixel phone photo (4000 × 3000) gives 471 DPI: short of 600, so it would be upscaled or printed softer.
- A 24 megapixel camera photo (6000 × 4000) gives 706 DPI: enough.
- A 48 megapixel photo (8000 × 6000) gives 941 DPI: enough.
At 600 DPI the pixels of a print blend together from about 5.7 inches (15 cm) away. 600 DPI is used for line art, small text and scans that will be enlarged. It is also the native resolution of many office laser printers.
