8, 16, or 20 Feet: Which NH Storage Container Size Fits?
✔ NH-Based Dispatch
✔ 603-369-4464
The single question we hear more than any other is a simple one: what size container do I actually need? Order too small and you are stuck making a second trip or renting a second unit. Order too big and you are paying for air and wrestling with a load that shifts around on the drive. The good news is that MI-BOX of New Hampshire keeps it simple with three sizes: 8-foot, 16-foot, and 20-foot. Here is how to match the right one to your project without guesswork.
Start With What You Are Storing, Not the Square Footage
People often try to reverse-engineer a container size from their home’s square footage, but that number is misleading because it includes hallways, bathrooms, and closets you are not emptying. A far better method is to count the rooms’ worth of furniture and boxes you actually plan to load, then add a little margin for the awkward items, like bikes, a lawnmower, or a mattress, that never stack neatly. Walk the house and tally it in rooms. That single habit gets most NH homeowners to the right size on the first try.
As a quick starting point, think of it in rooms: one to two rooms points to the 8-foot, three to four rooms points to the 16-foot, and five or more rooms points to the 20-foot. Those are guidelines, not hard limits, because how you pack matters as much as how much you own. A garage full of loose gear eats space faster than the same volume packed into uniform boxes, so when your load is bulky or oddly shaped, round up rather than down.
The 8-Foot MI-BOX: Small Jobs and Tight Driveways
The 8-foot container is the workhorse for focused projects. It comfortably holds roughly a room or two of furniture and boxes, which makes it the right call for a studio or one-bedroom apartment, a dorm or seasonal cleanout, or the classic staging move where you pull excess out of the house before it goes on the market. It is also the easiest to place, so when a driveway is short or steep, the 8-foot is often the only unit that fits without blocking the garage or the sidewalk. Think of it as the surgical option: one clear job, in and out.
The 16-Foot MI-BOX: The Most Popular Choice
If you are not sure where to land, the 16-foot container is usually the answer, and it is the size most NH households end up choosing. It swallows roughly three to four rooms’ worth of belongings, which covers the typical two- or three-bedroom home, a mid-size move, or a whole-room renovation where the furniture needs to disappear for a few weeks. It hits the sweet spot on value: big enough that most families finish in a single container, small enough to sit on an average suburban driveway without drama. When people describe a normal household move, this is almost always the box they mean.
The 20-Foot MI-BOX: Whole-Home Moves and Big Projects
The 20-foot container is built for the big lifts. It handles roughly a four-bedroom home or larger, a full-house move, a major renovation, or a garage and basement cleanout that has been building for a decade. It is also the one contractors and small businesses reach for when they need real capacity for equipment, seasonal inventory, or jobsite materials. The trade-off is footprint: it needs a genuine stretch of flat, accessible driveway. If you have the room and the volume, though, consolidating into one 20-foot unit beats juggling two smaller ones.

When to Size Up, and When to Rent Two
A few rules of thumb save people from the most common sizing mistakes:
- When you are on the fence between two sizes, size up. The cost difference is modest next to the headache of running out of room mid-load.
- Loading over several weeks? Lean smaller and stage it. If you are packing slowly while your home is listed, an 8-foot you fill and swap can be tidier than a half-empty 20-foot sitting for a month.
- Storing long-term? Leave a walkway. Do not pack a container wall to wall if you will need to reach items later. Size up one step so you can keep an aisle.
- Big move plus a tight driveway? Two drops beat one squeeze. Two 8-foot or 16-foot units delivered in sequence can move a whole house even when a 20-foot cannot physically fit.
And remember there is no 12-foot option to agonize over. With three clear sizes, the decision comes down to how many rooms you are moving and how much driveway you have to work with. When in doubt, describe the job to us and we will point you to the size that fits.
