The working
Pixels are inches multiplied by the resolution.
- Width: 5.5 in × 150 = 825, which rounds to 825 pixels.
- Height: 8.5 in × 150 = 1,275, which rounds to 1275 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 863 × 1313 pixels.
