Enter your pixel dimensions and instantly see every standard poster, photo, and art print size your image supports — at 300 DPI, 150 DPI, and 72 DPI.
Open the Calculator →The most common problem when printing digital files is discovering too late that the image doesn't have enough resolution for the intended size. The relationship is straightforward: a 3000 × 2400 pixel image at 300 DPI (the standard for print quality) produces a 10 × 8 inch print. The same image at 150 DPI produces a 20 × 16 inch print — twice the size, but visibly softer. PrintCalc works in both directions: enter your pixel dimensions to see every size your image supports at each quality tier, or enter the print size you want to find out how many pixels you need.
The 300 DPI standard exists because human vision stops resolving individual dots at about that density when viewing print at normal reading distance (roughly 12–18 inches). For large-format prints hung on a wall — banners, trade show graphics, and posters viewed from several feet away — 150 DPI is perfectly adequate and often indistinguishable from 300 DPI to the naked eye. The guides below explain when each quality level is appropriate.
Aspect ratio matters as much as resolution. An 8×10 print uses a 4:5 ratio; a 4×6 print uses a 2:3 ratio — the same ratio as most DSLR and mirrorless camera sensors. Printing a DSLR image at 8×10 without cropping is impossible without either white borders or significant cropping at the top and bottom. PrintCalc flags which standard sizes match your image's aspect ratio exactly and which will require cropping.
The reference guides below cover the most common print size questions, including Etsy digital download requirements and standard poster dimensions.

Read guide →300 DPI is the standard for professional print quality — it's what print labs use as the minimum for sharp output. 150 DPI works for large-format prints viewed from a distance. 72 DPI is screen resolution only and will produce blurry prints. For anything you'll frame or send to a print lab, aim for 300 DPI.
Divide your image width in pixels by DPI to get print width in inches. A 3000 × 2400 image at 300 DPI prints at 10 × 8 inches. At 150 DPI, the same image prints at 20 × 16 inches. PrintCalc does this automatically and shows every standard size your image supports at each quality level.
The most common US poster sizes are 11×14 (gallery/movie), 11×17 (event/tabloid), 18×24 (standard), and 24×36 (large theatrical). Standard frames are widely available for all four. Less common sizes typically require custom framing.
Provide files at 300 DPI at the largest intended print size. An 8×10 at 300 DPI requires a 2400 × 3000 pixel file. Include multiple aspect ratios: 4×6 (2:3), 5×7, 8×10 (4:5), and A4 for international customers.
DPI (dots per inch) technically refers to printer output; PPI (pixels per inch) refers to digital image resolution. In practice the terms are used interchangeably. When a print lab asks for 300 DPI, they mean 300 pixels per inch of the intended print size.
You can upscale with software, but you can't recover detail that was never there. Standard upscaling makes a blurry image larger and still blurry. AI upscalers (Topaz Gigapixel, etc.) can produce usable results for prints viewed from a normal distance, but native 300 DPI source always produces sharper results.
