In order to know how to select stools or chairs, it is fair to say that chair dimensions can vary drastically from design to design, especially considering the vast style options available. For instance the seat height on a bar stool can vary greatly from a standard kitchen chair.
For the most part though, it is fair to assume the following typical chair dimensions:
- Seat width: 16"-20"
- Seat depth: 15"-18"
- Seat height from floor: 18"-20"
- Armrest height (full): 8”
- Armrest width: 2"
- Average Set back of armrest from front: 2"-3"
- Seat back height: 16"-20"
