How big is JIS B5 in inches and pixels?

182 × 257 mm is approximately 7.1654 × 10.1181 inches, or 18.2 × 25.7 cm. At 300 ppi, portrait is 2150 × 3035 pixels; landscape swaps those counts. Pixel dimensions depend on the resolution you choose.

Will an ISO B5 design fit on JIS B5?

Its nominal outline fits with 6 mm spare width and 7 mm spare length. Printer margins and envelope or binder clearance may reduce usable space. A fit-to-page print command may enlarge the design; use actual size when its physical scale matters.

Is Japanese B6 the same as ISO B6?

JIS B6 is 128 × 182 mm; ISO B6 is 125 × 176 mm. Select them to compare both outlines, or compare JIS B6 against A6 at 105 × 148 mm. Do not infer a Japanese B dimension from the ISO B name.

Compare Japanese JIS B5 with ISO B5 · Compare ARCH with ANSI drawing sheets
For an existing PDF, place four A6 pages on an A4 or Letter sheet with PDF N-up; export there, then print at actual size. To convert arbitrary artwork dimensions, use Pixels to Print Size.

A4 and Letter are not interchangeable. A4 is 5.9 mm narrower and 17.6 mm taller. Changing document page size can reflow content; print-time fit scaling changes its physical size instead. Printer margins, borderless support, bleed and accepted paper depend on the device or print service. Nominal outline fit does not guarantee clearance inside an envelope. These diagrams compare sheets to each other, not to actual screen inches.
