RAW Series
SRA3+
Belonging to the ISO 216 standard, SRA3+ is a unique paper size that stands out in its category. This format, measuring 320mm x 450mm, offers an additional margin compared to the traditional A3 size. The extra space is specifically designed for print bleed - a critical aspect in professional printing where the printed area extends beyond the intended page size.
The SRA3+ paper size is part of the Supplementary Raw Format (SRA) series, which complements the A series in ISO 216. This series provides sizes that are slightly larger than their A-series counterparts, allowing for essential extras such as print bleed and trim allowance.

Interestingly, while most commonly used in countries adhering to ISO standards like Europe and Asia, SRA3+ has also found its place within industries globally due to its practicality. It's particularly favored by graphic designers and print professionals who appreciate its additional space for creative flexibility.
In comparison with ANSI standards predominantly used in North America, there isn't a direct equivalent for SRA3+. However, it closely aligns with ANSI B (11" x 17"), albeit offering more width and height. This difference further emphasizes SRA3+'s unique position within global paper sizes.
Ultimately, whether you're creating brochures or designing intricate layouts requiring professional printing techniques, SRA3+ offers an edge with its extra margin space - a testament to thoughtful design meeting practical needs.
