There are generally three different height measurements for kitchen and dining room tables: standard height (also sometimes called dining height), counter height, and bar height. The height refers to how far off the ground the eating surface of the table stands. The standard height for a kitchen or dining room table stands between 28 and 30 inches.
What is counter height? Counter height is anywhere between 34 and 36 inches off the ground, while bar height is even taller than that. Bar height tables have an eating surface that is anywhere from 40 to 42 inches off the ground.
To get a picture in your head of what each height table looks like, first imagine most dining room or kitchen tables you see. This is standard height or dining height. Next, imagine your kitchen counters, where you most likely prepare food, store kitchen appliances, and more. Named appropriately, this is counter height. Bar height is a little bit of a stretch up, close to what you'll see in restaurants and pubs where people gather for a drink.
