A good resolution for high-quality 8x10 prints is typically 2400 x 3000 pixels, which corresponds to 300 pixels per inch (PPI or DPI) at the 8x10 inch print size. This resolution ensures sharp detail and professional print quality. Key points:

• 300 DPI is the standard for photo-quality prints, so for an 8x10 print, multiply 8 inches by 300 DPI (2400 pixels) and 10 inches by 300 DPI (3000 pixels)

• A resolution of 2400x3000 pixels equals about 7.2 megapixels, which is sufficient for crisp, detailed prints at this size

• Lower resolutions like 240 PPI (1920x2400 pixels) can still produce good quality prints but 300 PPI is preferred for the best sharpness and detail

• For casual or poster-quality prints viewed from a distance, 150-200 DPI may be acceptable, but for close viewing, 300 DPI is recommended

In summary, for high-quality 8x10 prints, aim for a resolution of 2400 x 3000 pixels at 300 DPI. This ensures the print will be sharp, clear, and professional-looking.
