Formula
pixels = inches × DPI= 2400
Note
Simplified model: these are standard prepress and typographic relationships computed on nominal values. Real press bulk, paper caliper and shrinkage, ink limits for a given profile, font metrics and binding allowances vary by supplier and by job, so confirm with your printer and a proof before going to press.

How does this calculator turn a print size into a pixel count?+
It multiplies the physical width and height (in inches or centimeters) by your chosen PPI. A 6x4 inch print at 300 PPI needs 1800x1200 pixels; the same print at 150 PPI only needs 900x600 pixels.
What PPI should I target if I don't know the final printer?+
300 PPI is the safe standard for photo-quality output on most commercial and home printers. Going higher rarely adds visible detail since most printers and human eyes can't resolve much past that, so it mainly wastes file size.
Why does the calculator ask for units (inches vs. centimeters)?+
PPI is defined per inch, so centimeter inputs must be converted to inches internally before multiplying. Mixing up units is the most common reason people end up with an image four times too small or too large.
I need pixels for a large banner — can I just use a lower PPI?+
Yes, and you should. Banners and posters are viewed from several feet away, so 100-150 PPI looks sharp at that distance while keeping the file size and required pixel count manageable.
My camera or design software caps out below the pixel count this gives me — what now?+
You'll need to either lower the target PPI (acceptable if the print is viewed from a distance) or upscale the image, accepting some softness. There's no way to get more real detail than your source pixels contain.
