Packing Mistakes That Lead to Broken and Lost Items

Most of the damage that shows up when you unpack was not caused by the truck, the road, or bad luck. It was decided weeks earlier, in the way a box was filled, sealed, and labeled. A cracked serving bowl or a missing remote almost always traces back to a small choice made under time pressure or in the wrong assumption about how a box behaves once it leaves your hands. This guide walks through the packing mistakes that quietly create breakage and loss, why each one matters, and what to do differently. It covers the errors to avoid, not the full technique for packing a box correctly (see our guide on how to pack a box correctly) or which supplies to buy (see our guide on essential packing supplies).

Why Most Breakage and Loss Is Avoidable

A box in transit is not sitting still. It gets stacked, leaned on, slid across a truck floor, and jostled over thousands of feet of road. Items break when they can move inside the box, when the box itself collapses, or when the wrong things are stacked on top of each other. Items go missing when nobody can tell what is inside a box or whether it ever arrived. Both failure modes are predictable, which means both are largely preventable with attention up front.

There is also a financial reason to take this seriously, and it surprises a lot of people. If you hire a licensed interstate mover and pack your own boxes, the federal agency that regulates household moves notes that if the articles you pack are damaged, it may be more difficult to establish your claim against the mover for the boxes you packed. In plain terms, a box you sealed yourself is your responsibility in a way the mover’s own packing is not.

On top of that, the default liability level most movers carry, called Released Value protection, makes the mover responsible for no more than 60 cents per pound per article. A damaged ten-pound lamp recovers six dollars under that coverage, regardless of what it cost you. (How that coverage works in detail is covered in our guides on released versus full value protection and filing a damage claim.)

The takeaway is simple. Whether you are moving across town or across the country, the box you pack is the one you are most on the hook for. Packing it well is not busywork; it is the cheapest insurance you have.

Overpacking and Underpacking Boxes

The two most common mistakes pull in opposite directions, and both end in damage.

Overpacking is the urge to make every box “count” by cramming it full and heavy. A book box loaded to the brim can weigh more than anyone wants to lift safely, and weight is exactly what causes problems. An overloaded box strains its own seams, sags in the middle, and is far more likely to be dropped because whoever is carrying it loses their grip or their footing. Heavy boxes also tempt people to drag, kick, or set them down hard, and every one of those movements is a chance for what is inside to crack. Stairs make all of this worse (see our guide on moving boxes down and up stairs safely).

Underpacking is the quieter mistake. A box that is only half full, or full but loose, has empty space, and empty space is where damage lives. When the truck turns or brakes, the contents slide, tip, and slam into each other and into the box walls. A partially filled box also can’t bear the weight of anything stacked on top of it. Instead of supporting the load, the lid caves in and crushes whatever is inside.

The fix sits between the two extremes. You want each box full to the top so nothing shifts and the box can be stacked, but light enough that it holds its shape and can be carried without a struggle. A practical habit: put the heaviest items in small boxes and the lightest, bulkiest items in large boxes. That single rule prevents most overweight book boxes and most flimsy, half-empty large ones. Lift-test every box before you tape it. If you have to brace yourself to pick it up, take something out.

Skipping Cushioning and Wrapping

The mistake here is treating the box as the protection. It isn’t. The box keeps things contained and stackable, but it does nothing to stop the contents from knocking against each other. Cushioning does that, and skipping it is one of the surest paths to a box full of broken pieces.

Three errors show up again and again:

Leaving gaps. Any empty pocket inside a box lets items travel. Filler in the gaps, the corners, the top, and the bottom keeps everything locked in place so a sharp stop doesn’t turn into a collision.
Not wrapping fragile items individually. Two glasses packed naked will find each other on the first bump. Each fragile item needs its own wrap so glass never touches glass, ceramic never touches ceramic.
Forgetting the bottom and top layers. A rigid item resting directly on the box floor takes the full force of being set down. A cushioned bottom layer absorbs that shock, and a top layer keeps the lid from pressing down on the contents.

It is worth saying what cushioning is for rather than what to buy, since supplies are their own topic. The job is to eliminate movement and absorb shock. If you can shake a sealed box and hear or feel things rattling, it is not ready. Add filler until it goes quiet. That quiet is the sound of a box that will arrive intact.

A related error is mislabeling fragility in your own head. People reliably protect the obvious things, the wine glasses and the framed photos, and forget the lamp bases, the picture frames buried in a wardrobe box, the small electronics tucked beside heavier gear. If an item would be expensive or impossible to replace, it gets wrapped, full stop.

Poor Labeling and No Inventory

Breakage is one failure. Loss is the other, and loss is almost always a labeling and tracking problem rather than a packing one.

The mistake is sealing boxes with no clear marking and no master list. An unlabeled box is invisible. Movers and helpers can’t tell which side is up, which boxes are fragile, or which one holds the thing you need on night one. Worse, when a box doesn’t arrive, you may not even realize it is gone, because you never had a record of how many boxes existed in the first place. A box that nobody is counting is a box that can quietly disappear.

This matters well beyond convenience. If you use a professional interstate mover, the mover is required to prepare an inventory, a descriptive list of your shipment showing the number and condition of each item, and you and the mover both sign it. You have the right to note any disagreement before you sign, and you should keep your copy, because if an item is missing or damaged at delivery, your ability to dispute it may depend on those notations. The mover’s inventory and your own box list work together: one tracks the shipment, the other tells you what is inside each box and whether all of them showed up. Without your own count, you are trusting that nothing fell through the cracks.

This post is about the mistake of skipping the system, not the system itself. For how to build a labeling scheme that actually works, with what to write on every box, how to color-code or number, and how to keep a simple inventory, see our guide on how to label moving boxes. The mistake to avoid here is just as important as the method: never seal a box you can’t identify later, and never finish a move without a count of how many boxes you started with.

Leaving Packing to the Last Minute

Almost every mistake above gets worse under time pressure, which makes procrastination the mistake that multiplies the others. When you are packing in a panic the night before, you overstuff boxes to finish faster, you skip cushioning because it slows you down, and you stop labeling because you just want it done. Rushed packing isn’t a separate problem so much as a guarantee that the earlier ones happen.

Last-minute packing also forces bad triage. You sweep whole drawers and shelves into boxes without sorting, so fragile and sturdy items end up jumbled together, and things you meant to keep with you, chargers, medications, documents, get buried in a sealed box you can’t find. Decluttering goes out the window too, which means you pay to move and risk breaking things you didn’t even want.

The countermeasure is to start early and pack in layers of urgency. Begin with what you use least, off-season clothes, books, decor, spare linens, and work toward daily-use items, so the careful, fragile packing happens while you still have time and patience. Pack one room at a time and finish it before opening the next, which keeps your inventory honest and your fragile items wrapped instead of rushed. Keep a first-night essentials box out of the system entirely so the things you need immediately never get sealed away in the scramble (see our guide on packing a first-night essentials box). Time is the resource that makes good packing possible. Run out of it, and every other mistake on this list comes along for free.

A clean unpacking on the other end is mostly the result of unglamorous habits: right-sized boxes, no empty space, every fragile thing wrapped, every box labeled and counted, and enough runway to do it without panic. None of it is complicated. It just has to happen before the truck arrives, not after the damage is done.
