About Printer Paper Size

Who We Are

I am based in Fujairah, United Arab Emirates, where I live and work.

I'm Hafiz, and I run Printer Paper Size on my own. I have around ten years of experience as a technical support executive in customer support roles at multinational companies. My work has specialised in printer troubleshooting: diagnosing problems, explaining settings and helping end users resolve problems with their printers.

That experience shapes how I explain paper sizes here. Most paper problems people search for are not really about the paper itself. They are mismatches between the document size, the printer driver setting and the sheet loaded in the tray. A correct measurement helps, but it needs to be understood alongside those settings.

I also publish computer and printer troubleshooting videos on YouTube through my channel, BroExperts.

Our Story

The same questions kept recurring in support work. People needed a clear measurement, an explanation of a setting or a way to compare two sheets. Existing paper charts could be inconsistent, incomplete or buried in marketing pages. I built this site to bring those details together, with practical explanations that connect a size on a screen to the paper going into a printer.

What We Do

I publish paper dimensions, comparison diagrams and practical printing guides. You can compare two sheets, explore the printing tools or look up a size before changing your printer settings. I explain how units, orientation and printable margins affect the result, so a measurement is useful beyond the chart.

Trusted Sources and Measurement References

My printer support experience informs the explanations; published standards provide the measurement references. I link those sources so readers can check their scope and report discrepancies.

I check dimensions against the applicable published specifications. These are the references for the standardised families below; they do not imply endorsement of this site by a standards organisation.

• ISO 216 defines trimmed A-series and B-series paper sizes for writing paper and certain printed matter.
• ISO 269 specifies correspondence envelope sizes, including C-series envelopes. It is a withdrawn standard, retained here as a reference for those established dimensions.
• ANSI/ASME Y14.1 covers US engineering drawing sheet sizes and formats.
• DIN 476 (1922) is the German paper-format standard from which the A series derives.
• JIS P 0138 covers Japanese trimmed paper sizes, including the Japanese B series, which differs from ISO B.

A standard name matters as much as a size label. I keep that distinction visible so that similarly named sheets are not treated as interchangeable. When comparing two references, check the series, units and orientation first. A difference caused by rounding is not the same as a difference between two national formats. The original millimetre dimensions provide a useful starting point.

How precision and rounding are handled

ISO paper sizes are defined in whole millimetres. One inch equals exactly 25.4 mm; inch values are rounded for display. A rounded conversion does not change the underlying sheet dimensions. Pixel values depend on the chosen DPI, so a paper size alone cannot specify an image's pixel dimensions.

ISO B5 is 176 × 250 mm, while JIS B5 is 182 × 257 mm. These are different sheets, listed separately. Check the full designation before choosing a driver setting or comparing a measurement with a chart.

What this site is not

I do not sell paper and I am not affiliated with any printer manufacturer. A sheet size is not the same as a printer's printable area. That area depends on the model's margins, so matching the paper dimensions alone does not guarantee that content placed at the edge will print.

Corrections and feedback

If you believe a dimension is wrong, email printerpapersize@gmail.com. Include the page, the size designation and the measurement you are checking. I verify each report against the source standard before making a change.
