How big is a standard ice maker?#
Ice makers are either a built-in undercounter unit, 15 or 24 inches wide and 34 to 35 inches tall, or a small portable countertop model 10 to 15 inches wide. The table below covers the undercounter and portable configurations so you can plan a built-in bar or a countertop spot.
Standard ice maker dimensions by configuration#
| Configuration | Width (in) | Height (in) | Depth (in) | Best for |
|---|---|---|---|---|
| Undercounter built-in (15-inch) | 15 | 34–35 | 24 | a home bar or kitchen island |
| Undercounter built-in (24-inch) | 24 | 34–35 | 24 | high-volume entertaining |
| Portable countertop | 10–15 | 13–16 | 14–20 | renters and quick-cube batches |

Installation clearances for a standard ice maker#
- Counter cutout height: 34–35 in in of undercounter height a built-in ice maker needs to slide beneath a standard countertop.
- Front venting: A built-in ice maker vents through the front toe kick, so it can sit flush between cabinets with no side gap.
- Water and drain: An undercounter ice maker needs a water supply line and a gravity or pump drain within reach of the cutout.
Will your standard ice maker fit? Clearances and door swing#
A built-in undercounter ice maker fits a cabinet cutout the same way a dishwasher does — plan a 34-to-35-inch cutout height so it aligns with the counter, matching the 15 or 24-inch width to the gap and its 24-inch depth to the cabinet run. Leave room at the back for the water line and, on drained models, the drain connection. A portable countertop unit needs no plumbing or cutout; it just needs about 14 to 20 inches of counter depth and clearance around it for airflow. Measure the cabinet opening for a built-in, or the counter footprint for a portable, before buying.

Standard ice maker sizes by type: undercounter built-in (15-inch), undercounter built-in (24-inch), portable countertop#
The three ice-maker options suit different setups. A 15-inch undercounter built-in, 34 to 35 inches tall and 24 inches deep, is the standard home-bar choice, slotting into a narrow cabinet gap with a plumbed water line. A 24-inch undercounter built-in, the same height and depth but wider, makes more ice for entertaining or a busy kitchen. A portable countertop model, 10 to 15 inches wide and only 13 to 16 inches tall, needs no plumbing and sits on the counter for a rental or temporary use. Choose undercounter for a permanent, higher-output install.
