Pack a house safely by hinging at the hips instead of rounding the spine, keeping every load against your body, and capping box weight by size: roughly 16 kg for a small book box and 14 kg for a large linen box. Spread the work over eight to ten days, not one weekend.
What does safe lifting look like when you are packing?
Most packing injuries do not follow one heroic lift. They follow three hundred small lifts done with a rounded back.
The hip hinge is the movement that protects you. Stand close to the box. Push your hips backwards, let the knees bend as needed, and keep your chest facing forward rather than down at the floor. Your lower back holds its natural inward curve throughout. If the tailbone tucks under and the spine rounds into a C shape, you have stopped hinging and started bending.
Four rules govern every lift in a packing week:
- Test first. Tilt one corner. A corner that is hard to lift means a box too heavy to carry.
- Load close. Bring the box against your torso before you stand. Every 10 cm the load sits away from your body multiplies compressive force on the lumbar spine.
- Feet before shoulders. Step your feet around to change direction. Twisting the trunk under load is the fastest route to a disc injury.
- Exhale on effort. Brace lightly through the abdomen and breathe out as you stand.
The safest carry zone sits between your knuckles and your chest. The Canadian Centre for Occupational Health and Safety explains the reasoning behind load position and lifting posture.
How much should a moving box weigh in kg?
Box size tells you what belongs inside. Small boxes take dense items. Large boxes take bulky, light items. Reversing that rule produces a 30 kg box nobody can lift safely. The practical ceiling for a two-handed floor lift is about 20 kg, and lower over a long day.
| Box size | Volume | What goes in it | Target weight | Common mistake |
|---|---|---|---|---|
| Small (book box) | 1.5 cu ft, 42 L | Books, files, tools, canned goods | 11 to 14 kg | Filling it with hardcovers past 20 kg |
| Medium | 3.0 cu ft, 85 L | Small appliances, pantry goods, toys, shoes | 13 to 16 kg | Using it as a second book box |
| Large | 4.5 cu ft, 127 L | Linens, towels, cushions, lampshades | 11 to 14 kg | Adding dishes because the space is there |
| Extra large | 6.0 cu ft, 170 L | Duvets, pillows, winter coats, luggage | 7 to 11 kg | Reading the volume as permission to fill it |
| Dish barrel | 5.2 cu ft, 147 L, double wall | Plates, stemware, ceramics | 16 to 20 kg | Stacking plates flat, not on edge |
| Wardrobe | 10 cu ft with bar | Hanging clothing only | 9 to 14 kg | Loading boots into the base |
Write the weight class on the box, not just the room. A note reading “BOOKS, HEAVY, TWO PERSON” tells whoever lifts it what their spine is about to absorb.
Repetitive strain: the injuries that come from packing, not lifting
A packing week produces a specific pattern of complaints, and almost none involve a dramatic moment.
The crouch. Low cupboards keep you in a deep squat or half kneel for long stretches, loading the front of the knee. Use a kneeling pad and alternate which knee is down.
The tape gun wrist. A tape gun demands repeated wrist deviation and a hard thumb grip. Hundreds of repetitions in an afternoon irritate the forearm extensors and outer elbow. Swap hands every ten boxes and cut with a long arm stroke.
The stair carry. Descending stairs with a load is an eccentric task: the quadriceps lengthen under tension on every step. Take one step at a time, load in front of your hips.
The overhead reach. Move a step stool to reach closet shelves. A chair arm is a fall, not a shortcut.
Alternate task types every 20 to 30 minutes. Wrapping glassware seated is a genuine rest from carrying.
Packing it yourself versus hiring packers: cost, time and injury risk
Two packers finish a three-bedroom Calgary home in six to ten hours. One unpractised person needs roughly 25 to 35 hours across a week. Calgary rates run $60 CAD to $85 CAD per packer per hour, with a full-house pack often landing between $1,100 CAD and $2,600 CAD, plus $250 CAD to $500 CAD in materials. Those are ranges, and a quote shifts with stairs, access and glassware volume.
The health case sits separate from the cost case. A known disc problem, a dislocating shoulder, a recent surgery, a pregnancy, or emptying a parent’s house alone at 60 all change the arithmetic. Booking a crew for the kitchen and garage while you handle soft goods is a sensible middle path. Firms that sell packing services Calgary as a standalone line item, separate from transport, let you place paid labour exactly where your body needs it.
Ask whether packers are employees or subcontractors, and what happens if a box they packed arrives broken. The Canadian Association of Movers publishes consumer guidance at mover.net.
A packing-week schedule that spreads the load
Cramming a house into one weekend produces the day-three collapse. This nine-day plan keeps heavy days apart.
- Day 1: Buy materials and sort. No lifting. Decide what leaves the house.
- Day 2: Storage rooms and closets. Soft goods into large boxes. Two hours maximum.
- Day 3: Books, files and records into small boxes. The heaviest day, capped at three hours.
- Day 4: Rest from lifting. Label, book the condo elevator, confirm the truck.
- Day 5: Bedrooms. Wardrobe boxes and dressers. Mostly standing work.
- Day 6: Kitchen part one. Dishes and glassware into dish barrels, wrapped seated.
- Day 7: Rest or a light walk. Nothing over 5 kg.
- Day 8: Kitchen part two, pantry and appliances. Garage and tools.
- Day 9: Essentials box and final sweep. Nothing heavy before moving day.
Calgary adds constraints. Walk-ups in the Beltline and Sunnyside have no elevator, January stairs and alleys ice over, and a Chinook can swing the temperature 20 degrees in an afternoon. Book heavy carry days for the warmest daylight hours.
Hydration, breaks and pacing
Calgary sits at roughly 1,045 m above sea level, and indoor humidity often falls below 30 percent in winter. Both raise fluid loss during hard work. Aim for about 500 mL of water per hour of steady work, and eat a real meal rather than snacking through the day. Anyone on a fluid restriction for a heart or kidney condition should follow their physician instead.
Take a ten-minute seated break every hour, and set a timer, because absorbed packers notice fatigue only after form has degraded.
What genuinely needs two people or equipment
Some items are not a technique problem. They are a mass problem.
- Refrigerators: 100 kg to 140 kg. Appliance dolly with a strap, two people, defrosted 24 hours ahead.
- Washers and dryers: 60 kg to 90 kg each. Drums need transit bolts installed.
- Mattresses: a queen runs 25 kg to 45 kg and is awkward rather than heavy.
- Upright pianos: 180 kg to 400 kg. A specialist crew with a piano board.
- Gun safes: 150 kg to 400 kg. Specialist stair-climbing equipment.
- Aquariums: a 200 L tank weighs 30 kg empty, and must never move with water or gravel inside.
Team lifting fails on communication, not strength. Name one caller. Agree on the count, the route, and a word meaning “set it down now”. Match partners for height, because a 20 cm difference tips the load onto the shorter person.
Knowing when to stop
Pain radiating down one leg past the knee, numbness in a foot, or new weakness lifting the front of the foot means stop packing and contact your physician or a physiotherapist. Loss of bladder or bowel control alongside back pain is an emergency department visit. Chest pain or breathlessness during exertion means calling 911.
Soreness that eases within two to three days is ordinary. Pain that wakes you at night, or persists past a week, deserves an assessment. Albertans can reach a registered nurse through Health Link at 811. This article is general information, not medical advice.
Frequently Asked Questions
How much should a moving box weigh in kg?
Keep most boxes between 11 kg and 16 kg, with 20 kg as the ceiling for a two-handed floor lift. Small book boxes stop near 16 kg, large linen boxes near 14 kg. Lift-test every box before sealing it, because weight matters more than fullness.
How many days does it take to pack a three-bedroom house?
One unpractised person needs roughly 25 to 35 working hours, best spread across eight to ten days with rest days between heavy sessions. Two professional packers finish the same house in six to ten hours. Compressing the job into one weekend causes most packing injuries.
Can packing cause a repetitive strain injury?
Yes. Hundreds of tape gun cycles irritate the forearm extensors and outer elbow, prolonged crouching loads the front of the knee, and loaded stair descents strain the quadriceps. Rotating task types every 20 to 30 minutes and swapping hands reduces that repetition.
How much do packing services in Calgary cost?
Calgary packing rates run $60 CAD to $85 CAD per packer per hour, with full-house packing commonly quoted between $1,100 CAD and $2,600 CAD, plus $250 CAD to $500 CAD in materials. Prices vary with volume, fragile items and stair access, so collect three written quotes.
When should I see a physiotherapist after packing?
See a physiotherapist or your physician if pain radiates below the knee, if you notice numbness, tingling or weakness in a leg or foot, or if soreness has not improved after a week. Severe back pain with bladder or bowel changes needs emergency care immediately.
