A3 Paper Print Usages
The A3 paper feature is ideal for organisations that have a lot to say. The large surface area is perfect for conveying relevant company information, embroidering with bespoke visuals, or carving out crucial projects without being restricted in space.
An in-demand and cost-efficient paper size, A3 paper is most typically used to create a canvas, A3 poster, A3 flyer, and even a mathematical chart. A3 paper is multifunctional and used by a plethora of industries; a paper format most commonly used to render project activities and large scale presentations.
An additional advantage to A3 measurements is that this paper type is extremely lightweight. It can be hung on walls and bulletin boards or perhaps folded to formulate a flyer; this can then be handed out to passers-by or posted with a custom-made envelope as a mail-out campaign.
SRA3 vs A3 Paper Size
SRA is an abbreviated term that stands for ‘Supplementary Raw Format A’; a slightly larger size than its corresponding ‘A’ paper. In regards to desktop printers, commercial print machines simply can’t print edge-to-edge, so the extra SRA3 size allows flexibility and a little movement to get around this issue.
For example, if we are printing a blank or transparent A3 flyer, the SRA3 method will print in the middle of a sheet with around 3mm of extra print around the edges referred to as the ‘bleed’. The outer unprinted area is then trimmed down leaving a finished and perfectly trimmed edge-to-edge A3 print. As a London print shop, we supply flat sheet printing in SRA3 format to other trade printers; as it is an economical and highly efficient solution that keeps production costs at a minimum!
With a 320 x 450 mm generous SRA3 size, there is plenty of room to get your creative wheels turning with this desirable in-demand print size. One SRA3 sheet can print:
- 1 x A3
- 2 x A4
- 4 x A5

FAQ's
What is the difference between SRA3 paper and A3 paper?
SRA3 printing involves using paper sizes measured in SRA rather than “A” sizing. SRA stands for “supplementary raw format A” and is of a slightly larger size. For example, the standard measurements for A3 paper are 297mm x 420mm, whereas SRA3 paper’s measurements are 320mm x 450mm.
SRA sizes are larger than “A” sizes because the measurement takes into account the white border on the edge of the paper, this added paper area gives you more room for error when cutting your unfinished sheets as it acts as a deterrent away from cutting into your final product.
Although the product you will receive is larger than its standard “A” size, please ensure your artwork stays within the maximum printable area.
