Decision guide
Take width and height as separate measurements. The smallest quart label tells you only part of the fit.
Duo Mini 3QT is 10 inches wide and 11.2 high. RIO Mini 4QT is 13.82 inches wide and 10.08 high. Duo is the better fit for a narrow gap, while RIO can be better for a low shelf with spare width. Neither closed measurement means it is acceptable to cook in the cupboard.
Someone who cooks tomorrow’s lunch along with tonight’s dinner may get more from a six-quart vessel than a couple who make a single small meal. Servings cannot be predicted from nominal quarts. Look at a suitable recipe, its liquid requirement and the lower fill line for expanding foods.
Before heating, decide where an open or removed lid will go. The place where you operate it also has to meet the manual’s steam and surrounding-clearance rules. A shelf that is fine for storing the cooker can still be unsuitable for using it.

The shorter body is not the narrower one next to a standard six-quart Duo.
