At 100 DPI, each inch of print uses 100 pixels. Lower DPI stretches the same file over a larger area; higher DPI keeps the print smaller but sharper for close viewing.
Example print size at 100 DPI
A 3000×2000 px image at 100 DPI prints about 76.2 × 50.8 cm (quality: Suitable for viewing from a distance). Use the table below to compare other DPI targets with the same pixels.
Is 100 DPI good for printing?
It depends on viewing distance and content. Photo books and fine art usually aim near 300 DPI. Posters and canvas often look fine around 150 DPI. Billboard and banner work can be much lower.

FAQ
How big can I print at 100 DPI?
Take pixels ÷ 100 for inches on each side. Example: 3000×2000 px → 76.2 × 50.8 cm at 100 DPI.
Does raising the DPI number improve a small image?
No. Without more pixels, a higher DPI target only forces a smaller print if you want that density.
