Wrong size costs you: either you overpaid for unused space, or you got too tight and had to disassemble everything. Here's how to calibrate.
Operators use standards. The most offered:
1m³ — small boxes, documents, seasonal. Fits ~10 medium boxes.
2m³ — 1 big piece + boxes. Bike, appliance.
4-5m³ — 1 full bedroom (bed, wardrobe, nightstand + boxes).
6-9m³ — full 1-2 bedroom apartment.
10-15m³ — 3-bedroom house.
15-30m³+ — business, commercial inventory, large house.
Use a calculator that considers each item by typical market volume:
3-seat sofa: 1.2m³ · Double bed: 1.5m³ · Wardrobe: 2m³ · Fridge: 0.9m³ · Dining table: 0.9m³ · TV: 0.2m³ · Medium cardboard box: 0.1m³.
Sum it all, add 15-20% slack to circulate inside the box and reach the back.
Almost nobody has slack. Almost everyone overstuffs. That means:
• Furniture stacked at heights it can't bear (sofa on headboard → scratches).
• To grab a box at the back, you remove everything and rebuild.
• You give up storing a chair, it ends in the trash.
Diff between 5m³ and 6m³: typically $20-40/month. Diff between actually opening the box and disassembling everything per visit: 1 hour of your time per visit.
If you visit 2x/month, 1 extra hour = real money per year. Almost always greater than the size upgrade.
Sum volumes, add 15-20% slack, round up. Use [our calculator](/en/calculator/) or [ask our concierge](/en/contact/) with your item list.
