What Fits in Your Space, by Scale

The largest radius that fits a 4 by 8, a door, a shelf or a spare room, what will run on it in each scale, and what to build when a continuous loop does not fit.

Every page here is computed rather than written, so the figures match the calculator that produced them exactly. Where a figure is a hobby rule of thumb rather than a published NMRA standard, the page says so. Every table is plain HTML you can quote.
