Are you planning to get some excellent bar chairs for your home? Are you wondering how to buy bar chairs online that won’t need to be returned because of a height mismatch? It’s important to understand the bar chair height calculation. Whether it’s kitchen bar chairs, outdoor bar chairs or restaurant bar chairs, most of them tend to be 75 to 85 cm in height. Most tall bar chairs also, in general, don’t exceed 85 cm in height. That said, the top of any modern bar chair to the underside of the seat usually measures 20 to 30 cm, which is ideal for kitchen island settings. Before you plan to buy bar chairs online, keep your kitchen island setting or the outdoor seating arrangement in consideration.
