Why has this one been chosen? It’s actually fairly simple to explain and understand. If you look at the heights of restaurant bars and the unique bar tables, 30 inches is the perfect height. One other reason is the natural make up of the human body in terms of height; it works great for 30” barstools.
To look more in depth at why the 30 inch bar stool is considered standard height lets look at the home kitchen. The design of a kitchen in most homes has a countertop or island of some sort. The manufacturers have come up with a standard height of between 40-44 inches for these counters. This height works great for these bar stools and allows for ample leg room under the counter overhangs. The height is really comfortable for resting your elbows, eating dinner, or simply enjoying your favorite beverage.
The overhangs on a lot of counters or breakfast bars work great for the 30 inch bar stools. The space between the stool seats and overhangs are anywhere form 10-15 inches which is the perfect amount for an average persons leg to fit comfortably. This is another reason this bar stool works so well in a lot of different circumstances.
Because of the natural height of the human body a 30 inch seat
height puts the body in a really comfortable position when sitting. Most bar
stools have a foot rail of support beam halfway between the seat and the floor.
This allows the user a place to put their feet and take the pressure off their
thighs and buttocks. The most important thing is being able to sit in a comfortable
position without lower back pain for longer periods of time. This position works
well for common heights, as there are other heights available for those who need
it.
Another reason the 30 inch bar stool is considered standard
height is due to the bars and tables in restaurants and pubs. These tables sit
higher than the average dining table heights. So like the home counter heights,
they allow someone sitting on these stools to have comfortable leg room and
a good seating position to eat dinner and enjoy their favorite beverage.
