Anyone know a good resource for standard structural measurements? On my "To-Do" list is a scratch build, I know HO is 1:87, but I need to know what the 1:1 should be before I can make it 1:87.
Standard 1 story structure, standard door, standard garage door, etc etc...
It all depends on you and your taste. If you want a small square bungalow you can make a 20 by 20 (400 sq feet) or if you want a big house like 80 by 40 (3200 sq ft.) I would say the average garage door is around 9 ft. tall the average door around 6.5 tall and the aveage ground to roof peak is anywhere from 12 to 18 depending on roof angle. Just play around with it. For your calculation needs. http://www.csgnetwork.com/modrrscalecalc.html
Well... In all, previous replies were correct. It varies by the date, and location also. A building in modern California varies allot from 1880's Wild west, ect.
If you want it "correct" you have to find a prototype blueprint.
There's plenty of commercial doors & windows, such as Grandt Line & Pikestuff garage doors too. Thats another way at getting a default "correct" size.
Perhaps a nice resource would be the one of the archturectual design standard books from before CAD came around. They had all common standards for the era they were printed. These were not cheep when I was in practice but since CAD became the norm I am sure that older copies can be had for a song. If you are designing modern day then one of the inexpensive CAD consumer programs for house design would have what you need. Perhaps the cheepest way is to look at older copies of MR or RMC and study the plans they published.
