POD Size Calculator (USA)
Estimate how much portable storage space your move needs. Enter your rooms, boxes, and large items to see the total volume, the recommended container size, and how many containers it will take — with a side-by-side comparison of PODS, U-Box & PACK-RAT.

How to Use the POD Size Calculator
Estimate the storage volume your move needs, get a recommended container setup, and compare sizes across providers in four steps.
Pick your home profile
Choose a home size to auto-fill typical room counts, or select Custom to enter your own. Set the furnishing level to match how packed your rooms actually are.
Count your rooms
Enter bedrooms, living and dining rooms, kitchens, home offices, and garage or storage areas. Garages hold the most volume per room, so don’t skip them.
Add boxes, items & buffer
Count small, medium, and large boxes plus major appliances and bulky items, then set a loading buffer so there’s room to stack and secure everything safely.
Compare and save your result
Pick your provider to see the recommended container setup, how many units you need, and space utilization — then download the PDF report to share or quote against.
What’s Included
Everything you need to size portable storage with confidence — from room-by-room volume to a provider comparison.
Recommended container setup
Finds the smallest single container that fits your load, or the most efficient combination of units when one won’t do it.
Total volume in cubic feet
Builds your volume from room counts, box counts, appliances, and bulky items, scaled by how heavily furnished your home is.
Side-by-side size comparison
Compare every size a provider offers — units needed, total capacity, and how full each option would be — with the best fit flagged.
Loading buffer control
Adds breathing room to your estimate so items can be stacked and strapped properly, instead of assuming a perfectly tight pack.
Volume breakdown & charts
See volume split across bedrooms, living areas, kitchen, garage, boxes, and bulky items, with a category bar chart and distribution doughnut.
Downloadable PDF report
A branded two-page report with your recommendation, size comparison, volume breakdown, and full itemization — ready to print or share.

Built for Your Move
Whether you’re storing between homes or shipping a whole household, the calculator meets you where you are.
Container-move first-timers
Never booked a portable container? Ordering the wrong size means a second unit or a wasted delivery. Get the volume right before you reserve anything.
Provider comparers
Weighing PODS against PACK-RAT or U-Box? Container sizes differ between them, so run your volume through each to see which lineup actually fits your load.
Renovators & in-between movers
Storing part of a home during a remodel or a gap between closings? Count only the rooms going into storage and size a container around exactly that.
Get a Sharper Estimate
Seven quick habits that make your container-size estimate more reliable.
- 1Be honest about furnishing level. The multiplier moves your total by a wide margin. If closets are full and rooms are crowded, choose Packed full rather than Average.
- 2Don’t forget the garage. Garages, basements, and sheds carry more volume per room than bedrooms, and they’re the easiest space to overlook when counting rooms.
- 3Keep the buffer at 10–15%. Containers get loaded by hand, not by algorithm. A buffer leaves room to stack, pad, and strap without a last-minute repack.
- 4Two smaller units can beat one big one. If utilization comes out low, check the comparison list — a different size mix may waste far less space.
- 5Disassemble before you estimate. Bed frames, tables, and shelving pack much flatter than their listed volume, so you may fit more than the number suggests.
- 6Check driveway and permit rules. Container size is limited by where it can legally sit. Confirm clearance, surface, and any street-placement permit before booking.
- 7Confirm capacity with the provider. Published dimensions vary by region and change over time. Use this as a planning tool, then verify the exact unit you’re quoted.
Frequently Asked Questions
Answers to the most common questions about sizing a portable storage container.
How does the POD size calculator work?
It builds your total volume in cubic feet from three inputs: the rooms you’re moving, the boxes and large items you’re taking, and a loading buffer for stacking room. Room volumes are scaled by your furnishing level, so a packed home counts for more than a sparse one. That total is then matched against the container sizes your chosen provider offers to recommend the best setup, how many units you need, and how full each would be.
What size POD do I need for my home?
As a rough guide, the smallest containers suit a studio or a single room, mid-size units handle roughly a 2 to 3 bedroom home, and the largest sizes are aimed at 3 to 4 bedroom homes. Larger households commonly need more than one container. These are starting points only — a heavily furnished home can easily need the next size up, which is why the calculator sizes from your actual room and item counts rather than bedrooms alone.
How do PODS, U-Box, and PACK-RAT containers differ?
They offer different size lineups. PODS and 1-800-PACK-RAT each provide a small, medium, and large container, with the small sizes differing slightly between them. U-Haul’s U-Box uses a single, much smaller container instead, so a full-home move typically means several units rather than one large one. Because the sizes differ, the same volume can produce a very different recommendation depending on which provider you select.
What is the loading buffer and why does it matter?
No container packs to 100% of its rated volume. Odd shapes leave gaps, and you need working space to stack, pad, and strap items so nothing shifts in transit. The loading buffer adds a percentage on top of your belongings to account for that. Around 10 to 15% is realistic; raise it if you have many awkward items, lower it only if you’re confident in a very tight pack.
Is it cheaper to get one large container or two small ones?
It depends on the provider’s pricing and how efficiently each option fills. One container generally means one delivery, one pickup, and one transport charge, which usually favors a single larger unit. But if a large container would sit half empty, two smaller ones can waste far less space. Use the comparison list to see units needed and utilization for every size, then price those specific setups with the provider.
How accurate is the volume estimate?
It uses typical per-room and per-item volume figures, so treat the result as a solid planning ballpark rather than a guarantee. Real-world usage depends heavily on how you pack: disassembling furniture and filling gaps can gain you noticeable space, while awkward or fragile items lose it. Container capacities also vary by provider and region, so confirm the exact unit dimensions before you book.
