Standard boltless garage units are usually around 90cm wide.
Along 3m of wall, you can fit:
3 shelving units
That's 15 shelf tiers, giving roughly 2,100L of usable storage volume (assuming 5 tiers per unit).

Frequently asked questions
How much weight can garage shelving units hold?
It varies by product, but boltless steel shelving units commonly support 100-250kg per shelf, well suited to tools, paint tins and stored boxes. Always check the manufacturer's per-shelf weight rating before loading up heavier items.
Should I leave a gap between shelving units and the garage door?
Yes — check the clearance needed for an up-and-over or roller door to fully open before positioning units, and leave some space around a car if the garage is also used for parking.
Is it better to use fewer tall units or more shorter ones?
Taller units maximise storage for a given floor footprint, which usually matters more in a garage than shelf height, so it's generally worth going as tall as ceiling height and door clearance allow.
What should I store on the top shelves versus the bottom?
Keep heavier, frequently used items on lower or middle shelves for easy, safer access, and reserve the top shelves for lighter, less frequently needed items like seasonal decorations or spare parts.
