How Big Is a 0.7 Cubic Feet Microwave? Dimensions and Fit Explained

A 0.7 cubic feet microwave typically measures about 17 to 18 inches wide, 10 inches high, and 12 to 13 inches deep on the outside, though exact size varies by model.

A 0.7 cubic feet microwave is one of the most common compact countertop sizes sold in the US, and its exterior footprint is always larger than the cooking space inside it. That gap between the number on the label and the space it eats on your counter is where fit problems start.

The capacity figure describes the interior cavity only. Two microwaves with the same 0.7 cu ft rating can still sit differently on your counter, because width, depth, and height are set by each brand separately.

What Does 0.7 Cubic Feet Actually Measure?

0.7 cubic feet is the interior cooking volume, not the outer size. The cavity is the space your plate spins in; the cabinet around it adds insulation, the door, the control panel, and the turntable mechanism.

This is why a 0.7 cubic feet microwave can’t be sized from the capacity alone. A GE retailer listing reports a cavity of roughly 12 inches wide by 8-3/16 inches high by 12 inches deep on one 0.7 cu ft GE model, while the outside of that same class of unit runs wider and taller. Always shop from the product dimensions on the spec sheet, never from the cubic-foot rating.

Retail listings describe this size class for small kitchens, apartments, dorms, offices, and RVs: these are built for countertop placement, not built-in cabinets.

Real Dimensions From Current 0.7 Cu Ft Models

GE’s JES1072SHSS lists 10.1875 inches high, 17.3125 inches wide, and 12.75 inches deep. Midea’s MMC07S2AST lists 10.19 by 17.03 by 12.79 inches. Toshiba’s 0.7 CU. FT. Microwave Oven comes in at 9.5 high, 17.1 wide, and 12.2 deep.

Width varies by about a third of an inch, depth by more than half an inch, and height by nearly seven-tenths of an inch. That’s small on paper, but it’s the difference between clearing a cabinet lip or not.

Toshiba’s 9.5-inch height is the standout if you’re sliding a unit under a low cabinet. The 9.6-inch turntable means the largest plate it comfortably spins is a standard dinner plate, not a big serving platter. If that trade-off matters, it’s worth comparing how every model in this class handles plate size and power before committing, which is where a tested rundown of the best 0.7 cubic feet microwave options saves a lot of tab-hopping.

How to Check Whether One Will Fit

Measure the space first, then compare it against the product dimensions, not the shipping box. Shipping dimensions include foam and cardboard and can run several inches larger than the appliance itself — a common reason a “perfect fit” turns out not to be.

Add door swing to your math. An open door projects well past the closed depth, so a unit sitting 13 inches deep can need 30 inches or more of clear space in front of it.

Leave room for ventilation. GE Appliances, Midea, and Toshiba all publish clearance requirements in each model’s owner’s manual, and those numbers vary by unit. Check the manual before placing anything near a wall or inside a cabinet.

Common Fit Mistakes to Avoid

• Treating capacity as footprint. The 0.7 cu ft figure says nothing about width or depth.
• Using shipping size. Compare product dimensions, not the carton’s outer measurements.
• Forgetting the open door. Closed depth understates the real space needed during use.
• Assuming all 0.7 cu ft units match. Widths, depths, turntable sizes, and weights all shift between brands.

One caveat: current manufacturer listings for these three models don’t include stable direct pricing, so don’t anchor on a number before checking the retailer page yourself.
