First, measure the height of your counter or table and use the below chart to determine the proper bar stool height when shopping.
Short /Table Height Bar Stools
These stools are shorter than counter or bar height stools and can be a good alternative to chairs at the table.
Counter Height Bar Stools
These stools are the ideal height for a 36-inch counter top or to have on their own for extra seating. They are smaller than the typical stool you see in restaurant or bar and are a great addition to your home bar or kitchen space.
Bar Height Stools
A 30-inch stool is the perfect height for a standard 42-inch bar or counter top. These stools also work great in a workspace like the garage. These are the same size stools you see in a restaurant or bar and are taller than the average dining chair.
Additional measurements to consider when choosing a bar stool are the spaces between each stool and between the stool and the surface height.
For stool spacing, look to have about 26-30 inches measured from the center of one stool to the center of the stool next to it. This allows for optimal space for eating, working and socializing.
For leg spacing, account for 9-12 inches between the top of the stool seat and the bottom of your countertop or bar surface.
