UltraClipart♡ Read the number correctly
Pixels per inch (ppi) describes how densely an image's pixels are placed on paper. It is different from a printer's dots-per-inch setting. A 2,048-pixel image placed four inches wide has 512 ppi; the same file placed eight inches wide has 256 ppi. Nothing in the file has changed.
Around 300 ppi is a common starting point for detailed prints viewed closely, but it is not a universal pass/fail line. Ask your printer for its requirements. Adobe's explanation of printed image resolution describes the relationship between pixels and physical size.
Why the visible drawing can be smaller
The full exported canvas includes its transparent edges. A four-inch-wide image may contain a pumpkin that is only three inches wide inside that canvas. Crop empty space in the editor if exact visual size matters, then calculate again using the new export's dimensions. This calculator cannot see where the visible shapes begin.
Paper fit is not a printer guarantee
The calculation subtracts your chosen margins from the page size. Your printer may require a larger nonprinting area. “Use largest size that fits” preserves proportions and stays inside that calculated area; it does not add bleed, cut lines, or printer calibration. Measure a test print before producing repeated labels or cards.
What about vector PDFs?
A vector shape is not limited by a fixed raster pixel count in the same way. Use the studio's Print setup controls for paper, placement, and margins when exporting PDF. The calculator is primarily for WebP and other raster images you place in another document. Read our file format guide for the CMYK assumptions and PDF limitations.
