Convert Pixels per inch to Pixels per yard

Convert Pixels per inch (PPI) to Pixels per yard (px/yd) instantly and accurately.

Conversion Formula

px/yd = PPI × 36

About Pixels per inch

The pixel per inch (PPI) is the universal standard for digital image resolution, defining how many pixels occupy one linear inch in a digital image, sensor, or display. Formally referenced in ISO 12232 (digital still cameras) and EXIF/TIFF (tags 0x011A/0x011B), PPI is both a capture parameter (scanner/sensor density) and a display characteristic. Display milestones: Macintosh 128K (1984): 72 PPI; Apple iPhone 4 Retina (2010): 326 PPI - above the human perceptual threshold at 25 cm; iPhone 15 Pro (2023): 460 PPI. Print benchmarks: 150 PPI (large-format, 1 m viewing); 300 PPI (standard offset, ISO 12647-2); 400-600 PPI (fine-art Giclée). EXIF stores PPI as unsigned RATIONAL; the historical default is 72/1, a carry-over from the original Macintosh screen standard. 1 PPI = 1/0.0254 px/m ≈ 39.37 px/m = 2.54 px/cm.

About Pixels per yard

The pixel per yard (px/yd) is an imperial resolution unit used in textile printing, wide-format graphics, and fabric digitising, where roll widths and run lengths are measured in yards. The yard is exactly 0.9144 m = 36 in (Weights and Measures Act 1963; NIST Handbook 44), giving 1 px/yd = 1/36 PPI ≈ 0.02778 PPI. Wide-format inkjet printers (Roland RE-640, Mimaki JFX200) resolve up to 1440 DPI = 51,840 px/yd. Fabric digital printers for dye-sublimation operate at 300-600 DPI ≈ 10,800-21,600 px/yd. Flag and banner printing standard for photographic quality at 1 m viewing distance is ≈ 720 px/yd. 1 px/yd = 1/36 PPI ≈ 0.027778 PPI ≈ 1.111 px/m.
