3000 x 3000 pixels is a high-resolution square image built for print. At 300 DPI, the standard for sharp photo prints, that's exactly 10 x 10 inches; drop to 150 DPI, which still looks sharp on large posters and banners viewed from a few feet away, and the same file can print up to 20 x 20 inches.

Print resolution comes down to DPI: pixels divided by DPI gives you the print size in inches. A 3000 x 3000px image prints at 10 x 10 inches at 300 DPI, or up to 20 x 20 inches at 150 DPI.For color photo prints, canvas, and framed art, stick to 300 DPI. For posters and banners viewed from further away, 150 DPI still looks sharp and lets you print bigger from the same file.
Printing below about 150 DPI at your target size is where images start looking soft or pixelated. A 3000 x 3000px file gives you enough resolution to print up to 20 x 20 inches without hitting that limit.This size also holds up well for square-format art prints, album covers, and gallery pieces where viewers get close enough to notice detail.
Because it's well above what any screen displays, 3000 x 3000 pixels gives you headroom to crop or resize down for digital use without ever running short on detail.It's the safer choice any time you're not sure how big something will eventually be printed — you can always scale a large file down, but you can't add resolution back in after the fact.
