RAW Series
SRA1
Belonging to the ISO 216 standard, SRA1 paper size is a significant player in the international paper size arena. This format measures 640mm by 900mm, providing ample space for various printing and design needs. Its dimensions are strategically designed to allow for bleed during printing processes, ensuring a flawless finish post-trimming.
As part of the Supplementary Raw Format A (SRA) series, SRA1 holds a unique position. It's larger than the A series sizes, offering additional flexibility for commercial applications. This makes it an ideal choice for large-scale projects such as posters or architectural plans.

The SRA series is not as widely recognized as its A and B counterparts; however, its importance cannot be understated in professional settings where precision matters. The extra space provided by SRA1 allows designers and printers to push boundaries without compromising on quality.
Interestingly enough, despite being part of an international standard, the use of SRA1 varies greatly across different regions. While it's commonly used in Europe and Asia, it's less prevalent in North America where ANSI standards dominate.
SRA1 is more than just a paper size—it's a tool that enables creativity while maintaining high standards of precision and quality. Whether you're designing a poster or drafting an architectural plan, choosing SRA1 ensures your work stands out with professional-grade clarity.
