Average Size Of Microwave

Let’s be honest: you’ve probably never stood in your kitchen and thought, “Gosh, I wonder if my microwave is average-sized.” That’s fine—it’s not a question that keeps you up at night. But the truth is, the average size of a microwave is a sneaky little fact that can save you from buying a machine that either dwarfs your countertop or forces you to reheat pizza slices on their tiptoes.

So, what is the magic number? Most countertop microwaves hover around 1.1 to 1.6 cubic feet of internal space. That’s roughly the size of a small, sad cat or a large, happy loaf of bread. Externally, they’re usually about 20 to 22 inches wide, 12 to 15 inches tall, and 15 to 17 inches deep—though manufacturers love to fudge these numbers like a politician at a pie-eating contest.

The Goldilocks Zone of Nuking

Here’s a shocking fact: your microwave’s “average” size wasn’t chosen by scientists, but by pizza. Yep, the 12-inch diameter of a standard frozen pizza is the literal ruler engineers use. If your microwave is too small, you get cold crust edges. Too big, and you’re just showing off—and heating up empty space. So the average size is the Goldilocks sweet spot: just right for a pizza, a bag of popcorn, or a leftover burrito that’s seen better days.

But hold up—there’s a catch. That 1.1–1.6 cubic foot range isn’t universal. Compact microwaves (0.5–0.9 cubic feet) are essentially for dorms and sad office break rooms where hope goes to die. Meanwhile, family-sized monsters (2.0 cubic feet and up) can fit a whole rotisserie chicken, which sounds impressive until you realize it also takes up half your counter and weighs as much as a toddler with a cement backpack.

The Sneaky Truth About “Average”

You might think every microwave sold today is average, but you’d be wrong. Surprise! The most common size sold in America is actually 1.1 cubic feet, according to industry insiders. Why? Because it fits neatly under most cabinets without making you re-arrange your spice rack like a game of Jenga. Also, it’s big enough to reheat a plate of spaghetti, but small enough that you can still pretend your kitchen looks like a magazine cover.

Here’s where it gets weird: the average microwave’s height is often a lie. Many models list themselves as 12 inches tall, but that’s the body—the actual footprint includes a 2-inch butt (the ventilation hump). That hump is why your microwave doesn’t slide under a cabinet unless you measure after buying it. Welcome to adulthood.

Bigger Isn’t Always Better

You might be tempted to buy a 2.2 cubic foot behemoth, thinking you’ll cook a Thanksgiving turkey in it. You won’t. You’ll just use it to microwave coffee for three years. Besides, a too-big microwave actually heats less evenly, because the microwaves bounce around like pinballs in an empty warehouse. Stick to the average, and your food will thank you—no cold spots in your mac and cheese.

On the flip side, a too-small microwave (0.7 cubic feet) means you’ll be cutting TV dinners in half and angrily rotating plates like a DJ who hates their job. Avoid that. The average size is your quiet, reliable friend who never asks for much—except maybe a wipe-down every February.

Final Mini-Wave of Wisdom

So next time you’re at a big-box store, stare at the microwaves with newfound respect. The average size isn’t boring—it’s a brilliant compromise between “I need to heat this bagel” and “I live in a tiny apartment where my oven is also my laundry basket.” Remember: 1.1 cubic feet is the number that keeps the world spinning, one sad leftover at a time. Now go pop some corn—but double-check that your microwave is actually level. You’re welcome.
