If you model in N gauge you might like to have a go at answering the question from a fellow enthusiast.

“Could one of your readers please help me, by telling me what the smallest radius I could expect to have on a small N gauge layout to fit in either a box case or coffee table. I thought approx 2ft x 3ft max. I would like a figure of eight, or circle with extend loop on one end. Hoping one of your readers can help me.”
