Shelving units turn cluttered garages, basements, and closets into usable storage. The right shelf depends on what you store and how heavy it is. This guide covers the main types and the details that keep shelves safe.
Types of shelving
Steel boltless shelving is strong and easy to assemble, and it suits garages and basements. Wire shelving is ventilated and works for pantries and closets. Plastic shelving resists moisture and rust and is good for damp spaces. Wood or laminate looks nicer for living areas.
Weight capacity
Check the capacity per shelf, which is usually listed in pounds and assumes the weight is spread evenly. Do not exceed it, and put the heaviest items on the lower shelves for stability.
Anchoring
Tall shelving can tip, especially when loaded unevenly. Anchor it to a wall stud using the hardware or brackets recommended by the manufacturer, particularly in homes with children.
Measure and plan
Measure the height, width, and depth of your space, leaving room to walk and to open doors. Adjustable shelves let you change the spacing as your needs change.
Use bins and labels
Store small items in labeled, lidded plastic bins instead of cardboard boxes, which attract pests and absorb moisture. Group similar items together and keep the most-used items at eye level.
Garage and basement conditions
Temperature swings and humidity can damage some items. Raise items off the floor in case of leaks, and choose rust-resistant materials.
