Why 18"x26"? Revisited
Posted: Tue Aug 09, 2016 9:35 am
Hey Everyone,
I have never been able to find an answer to what I thought would be a simple question: Why are Records of Survey sheets 18" x 26" format?
A couple searches of these forums led me to part of the answer, thanks to this discussion http://clsaforum.californiasurveyors.or ... ize#p27184
The Statute of 1933, Chapter 506, Section 11(d), paragraph 2:
"Such record of survey shall be a map made in good draftsmanlike manner on one or more sheets of tracing cloth of good quality, of the uniform size of eighteen by twenty-six inches..."
My assumption is that this size was standard for "tracing cloth" at this time in the industry, but I can't find any proof of that, and you know what they say about assumptions. I would love it if someone has any additional information on the background of this size requirement. However, whatever the reasoning ultimately is, no modern paper size in any of the standardized systems has an exact equivalent to 18"x26", though there is an 18" US Web roll that exists. Web rolls are miles long and are intended for newsprint or other mass produced magazines, not single sheet products.
Paper sizes that come close:
ARCH C is 18" x 24" - 2" shorter in width. I have heard of people getting 18" ARCH C rolls, but most ARCH C rolls are in landscape width at 24".
ISO A2 is 16.5" x 23.4" - 1.5" shorter in height and over 2" shorter in width.
ANSI C is 17" x 22" - 1" by 4" shorter.
If we wanted to go to a larger size, giving ourselves more real estate instead of less:
ARCH D is 24" x 36"
ISO A1 is 23.4" x 33.1"
ANSI D is 22" x 34"
After 83 years of 18"x26" I think we might want to consider conforming to a recognized standard paper size. I know this isn't a "hot button" issue, and is probably trivial in the eyes of some, but I think adhering to national or international standards would be another step forward for the profession.
Is there a reason that 18"x26" should be kept as the requirement? Can we put those paper cutters to bed?
