The generally accepted standard is that the stripes should be spaced 2 1/2 feet apart. However, there may be some variance depending on the specific width of your parking lot. Consult with a professional to get the most accurate guidance for your unique situation.

It depends on the parking lot's design and the purpose of the stripes. Generally, they should be placed far enough apart so that cars can park between them without obstruction. However, if the lot is meant for a specific type of vehicle (like a bus), then the stripes may need to be closer together to accommodate that type of vehicle.
