A queen bed is 60" wide by 80" long.
A king bed is 76" wide by 80" long
Mock up how much aisle and nightstand space you would lose with a 16" wider mattress to determine if it would work for you. Don't just measure, put something on the existing mattress on each side of the bed that reduces your nightstand on each side by 8" (cabinets will need to be remade) and reduces the walk-around space on each side by 8".
ETA - it's quite likely the cabinets above the nightstands will also need to be remade (or removed completely) to accommodate the wider headboard and sleeping space. And of course a new bed platform top/hinge/struts for the larger size and added weight. With the increased overhang on each side of the bed platform itself, a beefier thickness of plywood top (heavier) might be required.
