Where can I find a website with all the singns needed on a layout? RR crossing, stop signs, warning signs ect. Also, what % do you print in for O scale?

I saw a few ad signs on here, what size do you print them in?

Look above on this site you will see a listing "signage" on the "Scenery Sourcelist"

I don't use a specific percent, rather bring the sign you want into something like paint, find out what size it will be when printed, then alter it to whatever size you require.

Check railfonts.com. Look at their Street Signs Font and Railroad Signs Font.
Nice thing about a font, you can make it as large or as small as needed with no degradation.

Goto Google and do a search, for example, stop sign. Then at the top of the page click on "Images". Google returns 157 million images that relate to the search term "stop sign". Usually it is easy to find a good image within the first couple pages of the search results. Click on the image you want and google will take you to the page where it found the image. Also at the top of that page it will have a button that says "see full size image". Click that and you'll see just the image. Right click and save the image to your computer.

The hard part is figuring out how to scale the image to print it out the proper size. This will be different on a case-by-case basis and you may have to experiment or do further research. For example, a stop sign is commonly 30 inches across opposite flats but also come in other sizes (24", 36", 48").

If you want a 30" sign to be 1:48 scale then divide 30" by 48 and you get 0.625 inches. If you need to convert 0.625" to a ruler measurement then multiple by 16 and you get 10 (16ths of an inch) which can be simplified to 5/8". So, the final print-out should be 5/8" across the sign. "what % do you print in for O scale?" will depend on the size and resolution of the image you saved and will be different on a case-by-case basis. The software you use my also effect your final print size. You'll have to play around to figure out how to get the exact final size that you want.
