What is the right A paper format for you?

The dimensions of the A-series paper sizes are determined by the ISO 216 international paper size standard. This originated in 19th century Europe and is the most commonly used page measurement standard.

If you are uncertain of what paper format size you should be using for your marketing media, then you can never go wrong in referring to the A-series. This series uses an aspect ratio of 1:√2, while the other sizes are defined by folding the paper in half, parallel to its smaller size. For example, the most frequently used paper size is the A4, which has a measurement of 210 x 297 mm or 8.27 x 11.7 in and is often used as flyers or standard-size posters.

Below is a list of A-format sizes which you can refer to as you consider using for your printing needs.

/* No-JS fallback: override the SSR collapsed state so full content is visible. The data-expanded="false" attribute is set in SSR to prevent FOUC for JS users; without JS there is no toggle to expand, so we must remove the truncation here. */ [data-split-content-block][data-expanded="false"] .split-content-body { max-height: none; overflow: visible; -webkit-mask-image: none; mask-image: none; }
