Spec sheets give width, depth and height, but the space a refrigerator really needs is larger. Doors need room to swing fully open; drawers need room to extend; most self-contained units need clearance around their air intakes and outlets; and a technician needs to reach the condenser and controls. Together these define the working footprint.
In Indian kitchens and shops, where space is expensive, footprint often decides the format: an undercounter instead of an upright, a sliding-door cooler instead of a swing-door one, a worktop instead of a separate table and refrigerator. Height matters too, especially under lofts, staircases and low ducting. Also check the delivery path: doorways, lifts, stairs and corridors the unit must pass through.
A cloud kitchen in Mumbai fitting out a 200-square-foot unit might choose two worktop undercounters and one upright freezer instead of a larger reach-in, because the reach-in's door swing would block the only aisle.
