How it works
- Physical width (inch) = Horizontal pixels/PPI; Fit inside print rectangle PPI = max(px/d); Fill rectangle with crop PPI = min(px/d)
- Worked example: 3000/300 × 2400/300 = 10×8 inch = 25.4×20.32 cm; 150 PPI ⇒ 20×16 inch
- Supported input limits: Horizontal pixels: 1 ≤ x ≤ 1000000; Vertical pixels: 1 ≤ x ≤ 1000000; Pixels per inch (PPI): 1e-12 ≤ x ≤ 1000000000000; Desired print width: 1e-12 ≤ x ≤ 1000000000000; Desired print height: 1e-12 ≤ x ≤ 1000000000000
Assumptions and limitations
Decimal SI prefixes use powers of 1000; binary IEC prefixes use 1024. One byte is eight bits. Transfer estimates assume constant throughput; video uses average bitrates and explicit overhead. Screen calculations assume square pixels. Printing preserves aspect ratio through fit or crop; image PPI is distinct from printer DPI. Exact storage ratios are retained; nonterminating decimal displays round to twelve places.
