Storage unit packing checklist
This free storage unit packing checklist estimates how many boxes and supplies you need, then prints a labeled plan you can pack from. It's built for storage moves, so it favors sturdy boxes and clear labels. No account, no sign-up, nothing to buy. Add your rooms below, then print or save the checklist.

How this works
- The tool is preset to a storage move — confirm the move type or adjust it if some items are going elsewhere.
- Add each room or space you're packing into storage and set roughly how full it is.
- Read your box count and supply list at the top, then tweak box sizes if you prefer heavier or lighter loads.
- Print or save the checklist and the box labels so every box is marked before it goes in the unit.
- Pack rarely-used spaces first and keep a running list of what's in the unit.
Packing tips
- Label every box on at least two sides and the top — in a packed unit you'll only see the side facing the aisle, so a box's most-visible face should tell you what's inside.
- Leave a walkable aisle down the middle and along one wall so you can reach boxes at the back without unloading the front.
- Keep boxes off a concrete floor — set them on a pallet, plywood, or a layer of cardboard, since bare concrete can wick moisture upward.
- Use sturdy, uniform boxes and don't overfill them; boxes on the bottom of a stack carry the whole column, and a crushed box in the middle brings the stack down.
- Pack heaviest boxes (books, tools, dishes) low and light boxes (linens, lampshades, décor) on top, keeping single boxes under about 40 pounds so they're safe to lift after months in storage.
- Skip anything that attracts damp or pests — no food, no liquids, no live plants — and toss a few desiccant packs or a moisture absorber in with fabrics and paper.
Frequently asked questions
How many boxes do I need for a storage unit?
It depends on how much you're storing, not the unit's size. Add the rooms or spaces you're packing above and the tool estimates a box count and supply list for you. A few pieces of furniture plus a closet or two often lands in the 15–30 box range, but your actual number can be higher or lower.
What kind of boxes hold up best in storage?
New or lightly-used corrugated boxes in a few standard sizes stack best and resist crushing. Uniform sizes let you build stable, square stacks. Avoid grocery or liquor-store boxes that have already been compressed, and reserve plastic bins for items most vulnerable to damp.
Are plastic bins better than cardboard for long-term storage?
For most items, sturdy cardboard is fine and stacks more predictably. Plastic bins with lids are worth it for things you most want to protect from moisture and pests — photos, documents, textiles, and electronics. Don't seal bins airtight if the contents were even slightly damp, since trapped moisture can cause mildew.
How should I arrange boxes inside the unit?
Put things you won't touch for a while at the back and along the walls, and anything you might need against the aisle. Leave a clear path down the center so you can reach the back. Stack heavy on the bottom, light on top, and keep stacks square and no taller than you can safely reach.
Should I label boxes differently for storage than for a move?
Yes — for storage, label the side of the box, not just the top, because boxes get stacked and you'll only see the vertical face. Include a short contents note and a number, and keep a master list (a photo of each label works) so you know what's in the unit without opening boxes.
Can I put anything in the checklist directly into storage without boxing it?
Furniture, mattresses, and appliances usually go in as-is, though covers or moving blankets help. The tool counts boxes and packing supplies for the items that need boxing; large furniture isn't boxed, so it won't add to your box total. Drain and dry appliances like fridges before storing them.
What shouldn't go in a storage unit?
Skip food, liquids, live plants, and anything flammable or perishable — most facilities prohibit these and they attract pests or leak. Be cautious with items sensitive to heat or cold in a non-climate-controlled unit, such as candles, vinyl records, electronics, and some fabrics.
