JIS B6 in pixels

1512 × 2150 px

at 300 DPI, the print standard · JIS B6 is 128 × 182 mm · 3.3 megapixels

JIS B6 size in pixels has no single answer, because a pixel is a length only once a resolution decides how many fit in an inch. The JIS B6 pixel size is 1512 × 2150 px at the 300 DPI print standard and 363 × 516 px at the 72 DPI screen convention — every resolution in between is in the table below.

JIS B6 at every resolution

A sheet of paper has no pixel size of its own. It has a physical size — 128 × 182 mm, or 5.04 × 7.17 inches — and a pixel count only appears once you choose how many pixels go in each inch.

What the file size means for JIS B6

At 300 DPI an uncompressed JIS B6 is 9.3 MB, and at 600 DPI it is 37 MB — four times as much, because doubling the resolution doubles both dimensions. That squaring is the reason large formats become unwieldy so quickly: the same 300 DPI that produces a manageable file at small sizes produces 9.3 MB here.

If a file is going to a printer, ask what they want before choosing. 300 DPI is the safe default and 150 is often enough for anything read from more than arm's length.

Setting up the canvas

Width:      1512 px
Height:     2150 px
Resolution: 300 pixels/inch
Colour:     CMYK for print, RGB for screen
Bleed:      3 mm on every edge → 1583 × 2220 px

The bleed figure is the one people forget: artwork that runs to the edge must extend 3 mm past it on all four sides, so the working canvas is larger than the finished sheet.

Frequently asked questions

What is JIS B6 in pixels?

There is no single answer — it depends on the resolution. At the print standard of 300 DPI, JIS B6 is 1512 × 2150 pixels. On screen at 72 DPI it is only 363 × 516.

What resolution should an JIS B6 document be?

300 DPI for anything going to a commercial printer, which makes the canvas 1512 × 2150 pixels. 150 DPI (756 × 1075) is acceptable for a draft or an internal document. Large formats read from a distance can go lower — a poster viewed from two metres looks sharp at 150 DPI, and dropping to it here saves 7.0 MB of file.

How big is an JIS B6 file at 300 DPI?

About 9.3 MB uncompressed at 24-bit colour — 1512 × 2150 × 3 bytes. Compression brings that down a great deal for flat artwork and very little for a photograph, which is why a print-ready JIS B6 PDF is usually tens of megabytes.

How many megapixels is JIS B6 at 300 DPI?

3.3 megapixels. For comparison, JIS B6 at 600 DPI is 13.0 MP — quadruple, because doubling the resolution doubles both dimensions.
