PAPER SIZE · PIXELS · DPI
Convert paper sizes and pixel dimensions
Calculate pixel dimensions for ISO, JIS, US Letter, Legal, ANSI, photo, and envelope sizes at a selected DPI/PPI. Convert pixel dimensions back to physical units.
Choose a page size, orientation, and resolution. Results include inches and metric measurements for print and screen planning.
What size should be recalculated?
By default, 300 PPI is a guideline for high-quality printing. For web layouts, 72–96 PPI is typically used. Printer DPI (drops per inch) is another characteristic. The fractional part can be separated by a period or comma.

DPI and PPI are not the same thing
The pixel density of the image is used for calculation: PPI (pixels per inch). The interface retains the familiar DPI/PPI signature. The calculation is simple: size in inches × PPI = size in pixels. The pixel size is rounded to the nearest whole number, so a slight difference when converted back is normal.
300 PPI is selected by default as a common benchmark for quality printing. For screen layouts, set to 72 or 96 PPI; the actual size of the image on the display depends on the pixel density of the screen and the viewing scale.

Possibilities of paper size converter
- ISO formats A/B/C, JIS B, US Letter/Legal/Tabloid, ANSI, Architectural Series, Photo Sizes and Envelopes.
- Converting sheet format to pixels and image size in pixels to physical units.
- Adjustable density 1–2400 DPI/PPI, popular presets from 72 to 600, portrait and landscape orientation.
- Custom size in mm, cm or inches, pixel rounding and search for nearby paper formats.
By default, 300 PPI is selected as a common benchmark for printed graphics. This is an image size calculation, not an adjustment to the printer's physical resolution.
