Do you run 1/24 or just 1/32? The 1/24 cars obviously need more space. Like Broman said, the places where you most need inside borders is in back-and-forth esses and inside tight hairpin curves.
If you have a single 60-degree curve between straights, probably a half-width border would be fine. If your curve is 180 degrees or more, you need a little more inside border, especially for 1/24 cars.
Also, if you run full magnets, your cars won't slide around as much and won't need much inside border. Without magnets, cars will swing around more and need more borders both inside and outside.
