Curve radius.

What is the difference between n ez track 11.25, 12.50, 14.00, 15.50, 17.50 and 19.00" curve radius?

A 11.25" radius will make a 22.50" diameter circle and a 19.00" radius will make a 38" diameter circle. Just double the radius on all of them to find out how big the circle. You will have to add a little extra for the total size. I don't know how wide the N track is but HO EZ is about 2" wide. With however wide the N EZ easy is, you add that measurement to the diameter. If the N track is 1.5" wide, then 19" radius would give you a total diameter of 39.5" around the outside edge.
Is that what you're asking?

Yes. Now I understand. Thank you.
