How Big Is .7 Cu Ft Microwave? Size Guide

ByMeghan Splawn

Introduction

When shopping for a compact microwave, one of the first questions most people ask is, How Big Is .7 Cu Ft Microwave? On the surface, the answer seems simple. A .7 cubic foot microwave is considered a small, compact unit. However, cubic feet alone do not tell the full story of what that size actually looks like in your kitchen, how much real cooking space you get, or whether it will fit the dishes you use every day.

The term “cubic feet” refers to the interior capacity of the microwave cavity, not the total box size you see on the shelf. Two different .7 cu ft models can have slightly different exterior dimensions depending on their shape, door style, control layout, and manufacturer design. For this reason, learning how to translate cubic feet into inches is far more useful than relying on the capacity number by itself.

This size guide is built for anyone trying to figure out if a .7 cu ft microwave is the right fit for a dorm room, apartment, tiny kitchen, office break area, RV, or as a secondary microwave. By the end of this guide, you will know the typical exterior and interior dimensions, what fits inside, how it compares to nearby sizes, how to measure your space correctly, and the practical details that matter before you bring one home.

What Does .7 Cu Ft Mean?

Cubic feet is a measurement of volume. For a microwave cavity, it is calculated by multiplying the interior width, height, and depth together and converting that number into cubic feet. The decimal “.7” means seven-tenths of a cubic foot of empty space inside the cooking chamber.

It is easy to think of cubic feet like the space inside a box. However, a microwave is not a perfect rectangle with open air from corner to corner. The waveguide, turntable, housing, and door frame all take up space that you cannot use for food. The rated capacity is the calculated interior volume, but the usable space is slightly less than that number suggests.

Another important point is that manufacturers measure the interior cavity, not the entire appliance. When you see “0.7 cu ft” on a product label, that refers to the cooking cavity. The exterior is always larger. This is the key reason why asking How Big Is .7 Cu Ft Microwave? needs both answers: the interior capacity and the real footprint.

Typical Exterior Dimensions of a .7 Cu Ft Microwave

While exact numbers vary by model, most countertop .7 cu ft microwaves fall into a fairly narrow range. Knowing this range will help you judge clearance without needing the exact listing in front of you at all times.

For the vast majority of units in this class, the exterior dimensions tend to look like this:

  • Width: 17 to 19 inches
  • Height: 10 to 11 inches
  • Depth: 12 to 14 inches

Some ultra-compact designs can land slightly under those numbers, while others with wider control panels or deeper doors can creep a little over. Depth is the one people often forget. A unit listed as 18 inches wide and 10 inches tall can still be 13.5 inches deep from the very front edge of the door to the rear of the cabinet body. If your space is tight between a wall and the front edge of your counter, that depth matters just as much as width.

Keep in mind that “depth” in many listings means the body depth. With the door closed, you are working with that figure. With the door open, you will need extra clearance in front of the unit to load and unload safely without bumping into anything.

Interior Dimensions vs Usable Space

To get a realistic idea of what fits, it helps to look at typical interior cavity sizes for a .7 cu ft microwave. These are usually smaller than the exterior by a couple of inches on every side due to the insulated walls.

Across most models, interior dimensions fall close to the following range:

  • Interior width: 12 to 13.5 inches
  • Interior height: 7.5 to 8.75 inches
  • Interior depth: 10 to 11.75 inches

The usable space is not a flat cube. Since most units use a circular turntable, the limiting factor is often the diameter of that turntable rather than the raw corner-to-corner depth. A dish that is almost as wide as the cavity may still not rotate freely if it is oddly shaped or if it is placed too close to the back wall.

For example, a rectangular casserole dish with straight, sharp edges can be trickier to rotate than a round plate of a similar width. Flat, round dishes tend to make the best use of the space in a compact cavity.

Turntable Size and Dish Fit

If you want a practical answer to How Big Is .7 Cu Ft Microwave?, look at the turntable diameter first. This is the number that predicts most of your everyday use.

Most .7 cu ft microwaves come with a turntable between 10 and 12 inches in diameter. Many fall right around 10.6 inches, with some models using an 11 inch turntable. A few very tight designs use closer to 10 inches. (See Also:Can We Bake Cake In Microwave Oven)

With a 10 to 11 inch turntable, here is a realistic breakdown of common dish sizes:

  • 6 to 8 inch plates: Fit with plenty of room and rotate with ease.
  • 9 inch plates: Often fit, but may be snug on some 10 inch turntables. On an 11 inch turntable, most standard 9 inch dinner plates fit comfortably.
  • 10 inch plates: Only fit on select models with a larger turntable and a more open cavity. Many .7 cu ft units will not have enough clearance for a true 10 inch dinner plate to spin without rubbing.
  • Soup bowls: Most standard microwave-safe bowls up to around 7 to 8 inches in diameter are fine.
  • Mugs: Tall, narrow mugs usually fit fine, though very wide-handled mugs can interfere with rotation in the tightest cavities.
  • Small rectangular leftovers containers: Fit best if they are narrower than the turntable and sit fully on it. Long, narrow containers often work better than wide square ones.

The height limit is just as real. With an interior height of around 7.5 to 8.75 inches, you can usually fit a standard mug or a covered bowl, but a very tall lidded container may leave little headroom. If a lid is domed, it can come uncomfortably close to the top of the cavity.

How Big Is .7 Cu Ft Microwave Compared to Other Sizes?

Context is the easiest way to understand this size. Comparing .7 cu ft to the sizes you see most often will show you exactly where it sits.

  • .5 cu ft: Noticeably smaller. Often closer to 15 to 17 inches wide, with a turntable around 9 to 9.5 inches. Best for very limited tasks like reheating small snacks or a single mug.
  • .7 cu ft: The sweet spot for compact use. Gives more room for a proper plate than a .5 cu ft without jumping to a mid-size unit. Common for dorms, studios, and tight countertops.
  • .9 cu ft: A clear step up. Usually wider and deeper, with a larger turntable around 11 to 12 inches. Easier to fit larger plates and a wider range of containers.
  • 1.0 cu ft: Considered a small full-size for many homes. Noticeably bigger footprint and more versatile for frozen meals with larger trays.
  • 1.1 cu ft and above: Mid to large by countertop standards. Less ideal for the tightest spaces that a .7 cu ft is designed for.

The jump from .5 to .7 is usually more noticeable in plate fit than it is in raw cubic feet. The jump from .7 to .9 is also noticeable, but comes with more counter space required. For many people with strict space limits, .7 hits the best balance between usable room and minimal footprint.

Will a .7 Cu Ft Microwave Fit Your Space?

Before buying, think in terms of a “zone”, not just the open counter area. A microwave needs safe clearance on more than one side to be used comfortably and to allow for normal airflow.

Here are the practical points to check for a countertop .7 cu ft unit:

  • Width: Leave at least the full exterior width of the unit, with a little breathing room if it sits near other small appliances.
  • Depth: Account for the full depth from wall to front of the unit. If you plan to open the door fully, measure from the wall to the point the open door would reach.
  • Height clearance above: Check the vertical space above the intended spot. Many cabinets sit low over counters. Even though the unit is only around 10 inches tall, overhangs can be tighter than they look.
  • Front clearance: You need unobstructed space in front to pull out hot dishes safely. Avoid placing it in a spot where you would have to reach across something hot.
  • Wall placement: Leaving a small gap to an adjacent wall is fine for most countertop models, but cramming directly into a zero-gap corner with zero front room is rarely practical.
  • Power access: Make sure a standard outlet is within reach without stretching a cord across a walkway or sink area.

For dorm rooms, look at the open counter space between a fridge and a wall. For studio apartments, check unused counter real estate away from the main cooking flow. For RVs, account for cabinet doors or slide-outs that may block access.

What Can You Actually Cook in a .7 Cu Ft Microwave?

Knowing the size is only half the task. Knowing realistic use cases will help you decide if it meets your needs. A .7 cu ft microwave is best thought of as a reheating and light cooking unit, not a replacement for a full-size oven.

Here is a realistic look at what tends to work well, and what tends to be a stretch:

  • Great for: Leftovers on a 9 inch plate, oatmeal, instant soups, steam-in-bag vegetables, frozen burritos, hot drinks, pre-packed microwave meals designed for small portions, and softening butter.
  • Usually fine: Small baked potatoes, reheating two small items separately (one at a time), warming tortillas, or heating a single serving of rice.
  • Often a stretch: Large frozen entrées in wide trays, family-size leftovers spread flat, wide square meal trays, or anything that takes a 10 inch plate and also needs room to breathe.
  • Not ideal for: Trying to fit large cookware, browning like a traditional oven, or cooking oversized frozen meals intended for 1.0 cu ft or larger units.

The trick with a .7 cu ft unit is to use smaller containers on purpose. Round, microwave-safe dishes will always give you more usable room than wide, blocky ones. If you already own a favorite 10 inch plate, it is worth checking turntable fit before committing to this size.

Measuring Your Space: A Step-By-Step Guide

To avoid guesswork, use this straightforward approach. Do this with a tape measure, not by eye. Taking five minutes here will save you from a poor fit later.

  1. Pick your exact spot: Decide the fixed location where the microwave will live. Do not measure “open counter” in general, measure that specific zone.
  2. Measure width: Measure the available width from the left boundary to the right boundary of that spot in inches. Write down the tightest point if anything slightly narrows it.
  3. Measure depth: Measure from the back wall (or the furthest fixed object behind it) to the front edge of the counter. This is your max allowed depth for the unit itself.
  4. Measure height: Measure from the counter surface up to the lowest obstruction above, such as a cabinet bottom, shelf, or microwave hood lip. Check this at the very spot, not in the middle of the room.
  5. Check door swing clearance: Imagine the microwave door fully open. Measure from the front edge of that imagined spot forward with nothing in the way. Make sure there is room to safely remove hot food.
  6. Account for cord reach: Measure the distance to the nearest available outlet from your chosen spot. Avoid routes that would run the cord behind other heat-producing items.
  7. Test with a template: Cut a piece of cardboard to 18 x 13 x 10.5 inches as a rough stand-in for a typical .7 cu ft exterior. Place it in the spot and test width, depth, door swing, and access. This is the most reliable low-cost test.

When comparing to a listing, use the exterior measurements for width, height, and depth against your available space. Use the turntable diameter and your own dishes to judge interior fit. Both matter.

Practical Comparison Table

The table below gives a realistic, side-by-side view of how .7 cu ft stacks up against nearby sizes. These ranges reflect the most common countertop models rather than outliers.

Size (cu ft) Typical Exterior (W x H x D) Typical Interior (W x H x D) Typical Turntable Diameter Best For Plate Fit
.5 cu ft 15″ – 17″ x 9″ – 10″ x 11″ – 12.5″ 10.5″ – 12″ x 6.75″ – 7.5″ x 9″ – 10.25″ 9″ – 9.5″ Very tight spots, minimal use Up to ~8″ to 8.5″ plate (snug)
.7 cu ft 17″ – 19″ x 10″ – 11″ x 12″ – 14″ 12″ – 13.5″ x 7.5″ – 8.75″ x 10″ – 11.75″ 10″ – 12″ Dorms, studios, small countertops Up to ~9″ on most models, rare 10″
.9 cu ft 18″ – 20″ x 10.75″ – 11.75″ x 13″ – 14.75″ 13″ – 14″ x 8″ – 9″ x 11″ – 12.5″ 11″ – 12″ Small kitchen with more counter room Most 9″ to 9.5″ fit, many 10″ fit easier
1.0 cu ft 19″ – 21″ x 11″ – 12″ x 14″ – 15.5″ 13.75″ – 14.75″ x 8.5″ – 9.25″ x 12″ – 13.25″ 11.5″ – 12.5″ Everyday use in a modest kitchen 9.5″ to 10″ common, more flexible
1.1 cu ft 20″ – 21.75″ x 11.5″ – 12.25″ x 15″ – 16″ 14.25″ – 15″ x 9″ – 9.5″ x 12.75″ – 13.75″ 12″ – 12.75″ Larger portions, more varied dishes 10″ fits on many, easier with wider trays

Use this table as a realistic benchmark. When you see a specific listing, compare its exact numbers to your measurements rather than assuming every .7 cu ft unit is identical. (See Also:Can Paper Cup Go In Microwave)

Tips and Best Practices

Getting the size right is only part of a good choice. These practical tips will help you make the most of a .7 cu ft microwave once it is in place.

  • Prioritize turntable diameter: If plate fit is your top concern, sort by turntable size first. This tells you more than cubic feet alone.
  • Go round when possible: Use round, microwave-safe plates and bowls. They use the circular turntable far more efficiently than wide squares.
  • Leave front room: Do not push the unit flush against anything in front. Give yourself enough space to open the door fully and pull a hot dish straight out.
  • Mind overhead clearance: Check cabinets again after placing the cardboard template. Overhangs are easy to miss until you test with a full-height mockup.
  • Keep it away from edge clutter: Leave a little breathing room so steam does not hit nearby items and so you have safe handling space.
  • Use appropriately sized portions: A .7 cu ft unit rewards smaller, evenly spaced portions. They heat more evenly and leave less risk of blocking rotation.
  • Check container height: Before reheating a tall dish with a lid, quickly test headroom with the empty cavity in mind. Domed lids are the most common culprits.
  • Measure twice for tight spots: For dorms and RVs, measure width, depth, and height at least twice. A quarter inch can matter more than you expect.
  • Think long-term dishes: If you plan to use this as your main microwave for a while, test with the plates and bowls you actually eat off of, not the smallest ones you own.
  • Keep ventilation in mind: Follow normal countertop placement. Avoid boxing it into a fully enclosed, unventilated cabinet unless the unit is explicitly designed for that use.

Common Mistakes to Avoid

Most fit issues come from a few repeated mistakes. Avoiding these will make your decision much easier when figuring out How Big Is .7 Cu Ft Microwave? for your exact space.

  • Relying only on cubic feet: Two .7 cu ft units can look very different. Always check exterior dimensions and turntable size.
  • Measuring counter area, not the usable zone: An open stretch of counter may still be blocked by a cabinet overhang, a wall lip, or a nearby appliance.
  • Forgetting door swing: Plenty of people check width and depth, but forget how far the door opens. This is especially important if the unit sits near a fridge side or tight wall.
  • Assuming a 10 inch plate will fit: Only some .7 cu ft models can handle a true 10 inch dinner plate. For many, 9 inches is the realistic max with safe rotation.
  • Ignoring rear clearance: Pushing tight to the very back wall is usually fine for most countertop units, but always match to the listed depth and keep cords clear.
  • Using a box size estimate: Guessing based on a similar looking unit is risky. Get actual numbers for the exact model or use the ranges with a cardboard template.
  • Buying for “just in case” trays: If you only ever use your .7 cu ft for a 9 inch plate and small bowls, a larger unit may be unnecessary. Buy for what you actually use most.
  • Forgetting height for tall containers: A wide mug with a lid or a deep bowl can hit the top even if the base fits on the turntable.
  • Measuring with items already in the way: Clear the spot completely before measuring. Remove canisters, racks, or anything else that would crowd the zone.
  • Overlooking the front edge: Depth listed as “12.75 inches” means from rear to front of the body. If that puts the front at the very edge with no room to pull food out, it will feel awkward every single time.

Frequently Asked Questions

How big is a .7 cu ft microwave on the outside?

Most countertop .7 cu ft microwaves measure around 17 to 19 inches wide, 10 to 11 inches tall, and 12 to 14 inches deep. Exact numbers depend on the model, so always check the exterior listing for the unit you are considering.

What are the interior dimensions of a .7 cu ft microwave?

The interior cavity is usually about 12 to 13.5 inches wide, 7.5 to 8.75 inches tall, and 10 to 11.75 inches deep. These are estimates for most units. The usable space is less due to the turntable and the shape of the cavity.

What size turntable does a .7 cu ft microwave have?

Most .7 cu ft microwaves use a turntable between 10 and 12 inches in diameter. Many land around 10.6 inches. This is the most helpful number for knowing whether your plates and bowls will rotate freely.

Will a 9 inch plate fit in a .7 cu ft microwave?

On the majority of models with a 10.6 to 11 inch turntable, a standard 9 inch round plate fits well. On some units with a true 10 inch turntable, a 9 inch plate can be snug. Always test with your actual plate if it is one you use daily.

Will a 10 inch plate fit in a .7 cu ft microwave?

In most cases, no. A full 10 inch dinner plate is too large to rotate safely in the typical .7 cu ft cavity. Only a few models with a larger turntable and a very open interior can manage it, and even then it is often tight. For most units, 9 inches is the realistic maximum.

Is a .7 cu ft microwave much bigger than a .5 cu ft?

Yes, in practical use. The .7 cu ft class usually allows for a proper 9 inch plate and more flexible container shapes, while a .5 cu ft often limits you closer to 8 to 8.5 inches. The footprint grows a little, but for many people the extra usable room is worth it.

How much bigger is a .9 cu ft compared to a .7 cu ft?

A .9 cu ft unit is typically wider and deeper by about 1 to 2 inches on the exterior, with a larger turntable. That extra room makes 10 inch plates easier to fit and gives more flexibility with wider frozen meal trays. However, it will take up noticeably more counter space than a .7 cu ft.

Where is a .7 cu ft microwave best used?

It is a strong fit for dorm rooms, small apartments, studio kitchens, office break areas, guest spaces, and as a secondary microwave. It is also a common choice for tight counter setups where every inch counts. (See Also:Are All Pyrex Microwave Safe)

Does the .7 cu ft rating include the turntable?

No. The cubic feet rating refers to the interior cavity volume of the cooking chamber. The turntable sits inside that cavity and takes up a small amount of the physical floor space, but the rated capacity is still based on the measured cavity volume.

How much clearance does a .7 cu ft countertop microwave need?

Use the full exterior dimensions as your base. Make sure you have the width and depth of the unit, enough height under any overhang, and unobstructed front space for door swing. A small gap to nearby items is reasonable, but avoid fully enclosing it with no airflow path.

Can you fit a small casserole dish in a .7 cu ft microwave?

It depends on the dish. A narrow, round small casserole may fit on a 10.6 to 11 inch turntable. Wide, square, or long rectangular casseroles are much harder in this size. If the dish cannot rotate freely, heating will be uneven, so rotation is more important than forcing it in.

What is the most practical way to know if a .7 cu ft will fit?

Measure your exact spot in inches, make a cardboard template to the exterior size of the model you are considering, test door swing, and test with the plates and bowls you actually use. This covers both space fit and real dish fit better than any single number.

Conclusion

So, How Big Is .7 Cu Ft Microwave? In simple terms, it is a compact countertop unit that most often measures about 17 to 19 inches wide, 10 to 11 inches tall, and 12 to 14 inches deep on the outside, with a 10 to 12 inch turntable on the inside. The interior cavity offers just enough room for most 9 inch plates and everyday small dishes, but true 10 inch dinner plates will be a stretch for many models.

The real answer is not just cubic feet, but the combination of exterior footprint, interior cavity, and turntable diameter. For tight spaces like dorms, studios, and small kitchens, this size strikes a practical balance between taking up minimal counter space and still being useful for reheating, warming, and simple meals.
