How wide is the seat on a drafting chair?

Most standard drafting chair seats range from 18" to 21" wide. Big and tall models typically offer 22"–24" seat widths. Seat width affects user comfort — a seat that's too narrow creates pressure on the outer thighs, while one that's too wide can prevent proper lumbar contact with the chair back. When selecting a drafting chair for multiple users, choose a width appropriate for your widest frequent user.
