Question: what is the standard width of a bar countertop?
Answer: Back bar tops are generally the same height as the front bar, but can vary. » Home bar tops are usually between 12- to 16-inches wide. Commercial bar tops vary from 20- to 28-inches in width, including a drink rail (or trough) on the server side of the bar. Drink rails are typically 3/4-inch deep by 4-inches wide.
