Moving boxes and shipping boxes are not the same job
A shipping box has to survive one trip through a courier network and then it is done. A moving carton has to be lifted repeatedly by people, stacked six or eight high in a truck, and in a commercial context often used again on the next job. That changes what matters:
- Handling strength over burst strength. Moving cartons are gripped, carried, and set down hard. Edge crush performance and a clean, square fold matter more than surviving a conveyor drop.
- Consistent sizing beats variety. Trucks load efficiently when cartons are the same footprint. A move done in eleven random box sizes wastes truck space and slows the load.
- Reusability has real value. A commercial mover that treats cartons as multi-use inventory rather than consumables gets a very different cost per job.
The practical takeaway: for moving work, standardize on two or three carton sizes and buy them in volume, rather than buying whatever sizes happen to be on hand.
Sizing the order: how many boxes do you actually need
These are working estimates, not guarantees. Adjust for how much paper your operation still keeps.
Office moves, per workstation:
- 4 to 6 small cartons for files, books, binders, and personal items
- 3 to 5 medium cartons for desk contents, peripherals, and supplies
- 1 to 2 larger cartons per shared area for lamps, signage, and bulky light items
- Add 15 percent overall, every move runs longer than the estimate
Common areas add up faster than people expect. A single supply closet, kitchen, or server room can absorb 20 to 40 cartons on its own. Walk each one before finalizing the count.
Residential jobs, rough guide per room:
- Kitchen: 10 to 15 cartons, weighted toward small and medium
- Bedroom: 8 to 12 cartons
- Living room: 6 to 10 cartons plus protective material for screens and glass
Why small cartons matter more than large ones
The most common mistake in a move order is skewing too large. Big cartons feel efficient and then get filled with books, files, or tools until nobody can lift them safely. That is how you get dropped loads, injury reports, and a split carton on a stairwell landing.
Rules that hold up on real jobs:
1. Dense contents go in small cartons. Paper, books, files, tools, hardware. If it is heavy per cubic foot, it goes in the smallest carton that fits.
2. Light and bulky goes in large cartons. Linens, cushions, packing material, plastic goods, empty containers.
3. Nothing over about 50 lbs per carton if people are carrying it by hand all day. Your team will be doing this for eight hours, not once.
4. Fill every carton to the top, even if the last few inches are packing material. A half-full carton collapses when something is stacked on it.
Tape, wrap, and the supplies people forget
Boxes are the part everyone remembers. These are the ones that run out mid-job:
Tape. Budget roughly one case of 36 rolls per 200 to 250 cartons, and more if your team is taping bottoms twice, which they should be on anything holding weight. Buying tape by the case rather than by the roll typically cuts the per-roll cost by around a third, and on a move you are always using more than you planned.
Stretch wrap. Not just for pallets. Wrap filing cabinets closed, bundle cables, secure drawers, protect upholstered furniture from dust, and hold loads to a dolly. On office moves, wrap consumption is often the difference between a clean job and a damaged-furniture claim. Keep both a standard hand roll and something narrow for bundling.
Labels and markers. Label the side of the carton, not the top. Once cartons are stacked in a truck or a receiving room, the top face is invisible. Mark the destination room, not just the origin, this is the single change that most shortens the unpack.
Dollies, straps, and blankets. Not packaging, but the thing that stops a supply plan from working if it is missing. Confirm availability before the move date.
Sequencing your supply so it arrives when you need it
The realistic failure mode on a GTA move is not buying the wrong boxes, it is running out at the wrong moment. Sequence the order in three waves:
1. Pre-pack wave, two to three weeks out. The bulk of your cartons, plus tape and markers, so staff can pack archives and low-use areas early.
2. Top-up wave, a few days out. Order the sizes you burned through faster than expected. This is where a local supplier matters, you are not waiting on a courier from another province.
3. Move-day buffer. Keep a reserve of small cartons, one spare case of tape, and a roll of stretch wrap on the truck. Something always needs to be re-packed on the spot.
For GTA jobs that means same-day local delivery, walk-in pickup at our North York location, or pickup-only at our Mississauga and Scarborough locations, so a shortfall on the morning of the move is an hour of inconvenience rather than a lost day.
What to do with the cartons afterward
For commercial movers, sort cartons into three piles at the end of every job: good enough to reuse as is, usable for internal storage only, and recycling. Flattened, dry, indoor storage keeps reusable cartons in service far longer. Corrugated loses meaningful strength when it gets damp, so a stack left in a yard or an unheated bay over a GTA winter is effectively write-off inventory by spring.
For a one-time office move, offer surplus flattened cartons to staff or to another local business before recycling them. They are still a saleable asset for somebody.
Your move supply checklist
1. Count workstations and common areas, then add 15 percent
2. Standardize on two or three carton sizes, skewing toward small
3. Cap carton weight at about 50 lbs for hand-carried loads
4. One case of tape per 200 to 250 cartons, bottoms taped twice on anything heavy
5. Stretch wrap for cabinets, cables, dollies, and furniture, not just pallets
6. Label the side of the carton with the destination room
7. Order in three waves: pre-pack, top-up, move-day buffer
8. Sort and dry-store reusable cartons the same day the job ends
